Varices

Varices are abnormally dilated submucosal veins, primarily in the distal esophagus or proximal stomach, that develop as a consequence of portal hypertension, most often due to chronic liver disease such as cirrhosis.^[1] These varices form collateral pathways between the portal and systemic venous systems when blood flow through the liver is obstructed, leading to increased pressure in the portal vein and subsequent enlargement of veins in the gastrointestinal tract.^[2] Esophageal varices are the most common type and pose a significant risk of rupture and life-threatening hemorrhage, particularly in patients with advanced liver disease.^[3] The primary cause of varices is portal hypertension, which arises from intrahepatic resistance in cirrhosis (accounting for over 90% of cases), often linked to alcohol abuse, viral hepatitis, or non-alcoholic fatty liver disease.^[4] Less common etiologies include prehepatic causes like portal vein thrombosis, posthepatic conditions such as Budd-Chiari syndrome or right-sided heart failure, and intrahepatic factors like schistosomiasis.^[2] Risk factors for development and bleeding include the size of the varices, presence of red wale markings on their surface, severe liver dysfunction (e.g., Child-Pugh class C cirrhosis), and continued alcohol consumption.^[4] Approximately 30% of patients with cirrhosis have varices at diagnosis, increasing to 90% over 10 years, with an annual bleeding risk of 5-15%.^[2] Clinically, varices are often asymptomatic until rupture occurs, presenting with sudden, massive upper gastrointestinal bleeding manifested as hematemesis (vomiting of blood), melena (black, tarry stools), or hematochezia (bright red blood in stool).^[1] Bleeding episodes can lead to hypovolemic shock, anemia, and hepatic encephalopathy, with a mortality rate of 10-20% within six weeks of the initial bleed.^[3] Diagnosis is confirmed via upper endoscopy, which allows visualization of varices and assessment of bleeding risk, while laboratory tests evaluate liver function and coagulopathy.^[1] Management focuses on prevention through non-selective beta-blockers (e.g., propranolol) or endoscopic band ligation for high-risk varices, with acute bleeding treated by vasoactive drugs (e.g., octreotide), endoscopic therapy, and balloon tamponade if needed; refractory cases may require transjugular intrahepatic portosystemic shunt (TIPS).^[3] Overall, varices represent a critical complication of portal hypertension, underscoring the importance of screening and early intervention in at-risk populations.^[2]

Overview

Definition

Varices are abnormally dilated, tortuous, and elongated submucosal veins in the gastrointestinal tract, typically measuring greater than 3 mm in diameter.^[5] They occur primarily in the esophagus, stomach, or rectum and represent a pathological response to elevated pressure within the portal venous system.^[1] This dilation distinguishes varices from normal veins, which maintain diameters under 3 mm and lack the tortuous elongation characteristic of varices.^[6] The term "varices" originates from the Latin varix, meaning a twisted or dilated vein.^[7] The condition was first systematically described in the 19th century in relation to portal hypertension, with French anatomist Marie Philibert Constant Sappey providing early observations of esophageal varices in 1859 through detailed postmortem examinations.^[5] These initial descriptions laid the groundwork for understanding varices as collateral vessels forming due to obstructed portal blood flow, though the full hemodynamic implications were not clarified until later.^[8] Varices differ from telangiectasias or angiomas, which are smaller vascular malformations involving dilation of superficial capillaries or arterioles, often less than 1 mm in diameter and confined to the mucosal surface rather than the submucosa.^[9] Telangiectasias represent ectatic changes in terminal vessels without the pronounced elongation seen in varices, while angiomas typically denote benign proliferative lesions rather than pressure-induced venous dilation.^[10]

Classification

Varices are classified anatomically based on their location within the gastrointestinal tract, which influences their clinical management and bleeding risk. Esophageal varices, the most common type, are dilated submucosal veins primarily located in the distal esophagus, within the lower 5 cm above the gastroesophageal junction.^[2] Gastric varices occur in the stomach and are subdivided using the Sarin classification: gastroesophageal varices type 1 (GOV1) extend along the lesser curvature as a continuation of esophageal varices; type 2 (GOV2) involve the fundus; isolated gastric varices type 1 (IGV1) are confined to the fundus; and type 2 (IGV2) appear in other gastric locations.^[5] Ectopic varices develop in atypical sites outside the esophagus and stomach, such as the duodenum, small bowel, colon, or anorectal region, while rectal varices specifically involve dilated veins in the rectum, distinct from common hemorrhoids.^[11] Etiologically, varices arise from portal hypertension, categorized as cirrhotic or non-cirrhotic based on the underlying cause. Cirrhotic varices result from intrahepatic portal hypertension due to chronic liver diseases like cirrhosis, which accounts for the majority of cases.^[12] Non-cirrhotic varices stem from prehepatic causes (e.g., portal vein thrombosis), intrahepatic non-cirrhotic etiologies (e.g., schistosomiasis or idiopathic non-cirrhotic portal hypertension), or posthepatic obstructions (e.g., Budd-Chiari syndrome).^[13] Morphologically, varices are graded by size, form, and endoscopic features to assess bleeding risk, with large varices (>5 mm) carrying a higher probability of hemorrhage.^[14] The Baveno criteria classify esophageal varices as small (<5 mm in diameter) or large (≥5 mm), incorporating high-risk stigmata like red wale signs—longitudinal, dilated venules resembling whip marks on the variceal surface.^[5] The Japanese Research Society for Portal Hypertension system further details form (F1: small, straight; F2: enlarged, tortuous; F3: nodular, coil-shaped), color (white or red-blue), and red color signs (e.g., red wale marks, cherry-red spots, or hematocystic spots, graded by density as +, ++, or +++).^[5] In patients with cirrhosis, esophageal varices are present in 50-60% of cases, while gastric varices occur in approximately 20%.^[14]^[15]

Epidemiology

Prevalence and Incidence

Varices, particularly esophageal and gastric types, occur in 40% to 80% of patients with cirrhosis, with prevalence increasing alongside disease progression from compensated to decompensated stages.^[16]^[14] In compensated cirrhosis, varices are detected in approximately 30% to 40% of cases, while rates approach 80% or higher in decompensated cirrhosis.^[17]^[18] The annual incidence of new variceal development among cirrhotic patients without prior varices is about 8%, reflecting the progressive nature of portal hypertension in chronic liver disease.^[19]^[20] Regional variations in varices prevalence are closely tied to underlying etiologies of cirrhosis. In Europe and North America, where alcohol-related liver disease accounts for 50% to 60% of cirrhosis cases, varices prevalence among affected patients ranges from 50% to 60%.^[20]^[21] In Asia, dominated by viral hepatitis (particularly HBV and HCV), prevalence is approximately 50% to 70% in cirrhotic populations, with variations due to earlier detection and intervention in viral cases.^[21]^[22] In Africa and South America, schistosomiasis contributes significantly in endemic areas, where 20% to 50% of individuals with advanced schistosomal liver disease develop portal hypertension and varices.^[23]^[24] The annual incidence of first variceal bleeding in untreated patients with medium to large varices is 15% to 25%, underscoring the high risk in advanced cases.^[2]^[20] As of 2025, epidemiological trends show a decline in varices-related complications in high-income countries, driven by direct-acting antiviral therapies that have reduced hepatitis C prevalence and associated cirrhosis by up to 20% since 2015.^[20]^[25] Conversely, rising non-alcoholic fatty liver disease (NAFLD)—now termed metabolic dysfunction-associated steatotic liver disease (MASLD) to better reflect metabolic factors—affecting over 30% of adults globally and emerging as a leading cirrhosis cause in Western regions, is projected to increase varices incidence by 10% to 15% over the next decade. Global incidence of variceal bleeding in cirrhosis is estimated at 10-20% annually for at-risk patients.^[26]^[21]

Risk Factors

The development of varices is primarily driven by underlying conditions that cause portal hypertension, with cirrhosis being the most common etiology.^[2] Among cases of cirrhosis leading to varices, alcohol-related liver disease accounts for approximately 40% in the United States, often resulting from chronic heavy consumption.^[27] Chronic viral hepatitis B and C contribute to about 30% of cirrhosis cases associated with varices, particularly in regions with higher prevalence of these infections.^[28] Non-alcoholic fatty liver disease (NAFLD), now termed metabolic dysfunction-associated steatotic liver disease (MASLD), now accounts for approximately 20-25% of cirrhosis cases in the US, emerging as a leading cause alongside alcohol-related disease, as viral hepatitis contributions have declined.^[29] Other notable risk factors include portal vein thrombosis, which underlies 5-10% of variceal cases through non-cirrhotic portal hypertension.^[30] In endemic regions such as parts of Africa, South America, and Asia, schistosomiasis is a significant cause, leading to presinusoidal portal hypertension and varices in affected populations.^[31] Congenital or inherited liver diseases, including conditions like alpha-1 antitrypsin deficiency or Wilson's disease, represent rarer contributors to variceal development.^[32] Modifiable risk factors play a key role in preventing variceal formation. Excessive alcohol intake exceeding 40 g per day for men or 20 g per day for women substantially elevates the risk of alcohol-related cirrhosis and subsequent varices.^[33] Obesity, defined as a body mass index greater than 30 kg/m², promotes NAFLD progression to cirrhosis and varices, particularly in the context of metabolic syndrome.^[33] Untreated HIV co-infection with hepatitis B or C accelerates liver fibrosis and increases the likelihood of varices by up to threefold compared to hepatitis alone.^[34] Non-modifiable risk factors include demographic characteristics that influence variceal prevalence. Male sex is associated with a 1.5:1 higher risk of developing varices compared to females, likely due to differences in disease progression and exposure patterns.^[32] Advanced age over 50 years correlates with increased variceal incidence, as cumulative liver damage from chronic conditions accumulates over time.^[32]

Pathophysiology

Portal Hypertension

Portal hypertension is defined as an elevation in the hepatic venous pressure gradient (HVPG) exceeding 5 mmHg, with normal values typically ranging from 1 to 5 mmHg; values above 10 mmHg indicate clinically significant portal hypertension, at which point complications such as variceal formation become more likely.^[12] This condition arises from increased resistance to portal venous flow and/or augmented blood inflow into the portal system, leading to sustained elevation in portal venous pressure, which normally measures 5 to 10 mmHg.^[35] Portal hypertension serves as the hemodynamic prerequisite for the development of portosystemic collaterals, including varices.^[36] The classification of portal hypertension is based on the anatomic site of obstruction or resistance to blood flow, divided into prehepatic, intrahepatic, and posthepatic categories. Prehepatic causes involve obstruction before the liver, such as portal vein thrombosis or splenic vein thrombosis, without altering hepatic architecture.^[12] Intrahepatic portal hypertension, the most common form, results from liver parenchymal diseases like cirrhosis, where sinusoidal obstruction syndrome or schistosomiasis leads to increased intrahepatic resistance; cirrhosis accounts for the majority of cases in Western countries.^[12] Posthepatic causes occur due to obstruction after the liver, exemplified by Budd-Chiari syndrome (hepatic vein thrombosis) or right-sided heart failure, which back up pressure into the portal system.^[12] In cirrhosis, the primary pathogenic mechanism involves a marked increase in intrahepatic vascular resistance due to architectural distortion from fibrosis, regenerative nodules, and endothelial dysfunction, which narrows sinusoids and impairs vasodilation.^[36] This fixed resistance is compounded by dynamic factors, including hepatic stellate cell activation and reduced nitric oxide bioavailability.^[36] Concurrently, splanchnic vasodilation—driven by bacterial translocation, shear stress, and increased vasodilators like nitric oxide and carbon monoxide—expands the splanchnic vascular bed, elevating portal inflow and exacerbating the pressure gradient.^[37] This dual mechanism of increased resistance and inflow characterizes the hyperdynamic circulation in advanced liver disease.^[38] The gold standard for measuring portal hypertension is the HVPG, calculated as the wedged hepatic venous pressure (WHVP, reflecting sinusoidal pressure) minus the free hepatic venous pressure (FHVP), obtained via hepatic vein catheterization.^[39] An HVPG greater than 5 mmHg confirms portal hypertension, while reductions below 12 mmHg post-intervention predict low risk of complications.^[39] Non-invasive estimates, such as transient elastography or shear-wave elastography, assess liver stiffness as a surrogate for fibrosis-related resistance, with stiffness values above 20-25 kPa correlating with clinically significant portal hypertension in cirrhosis patients.^[40] These ultrasound-based techniques offer accessible screening but require validation against HVPG for precision.^[40]

Variceal Formation

Varices form as a pathological adaptation to portal hypertension, where increased portal pressure drives the development of portosystemic collateral circulation to decompress the portal system. In the esophagus, this occurs primarily through shunting via the left gastric (coronary) vein, which drains into the azygos vein through submucosal esophageal veins, forming dilated collaterals known as esophageal varices.^[2] This shunting increases blood flow and pressure within these veins, leading to progressive dilation.^[19] The mechanical stress on these veins follows Laplace's law, where wall tension (T) is proportional to transmural pressure (P) multiplied by radius (r) divided by wall thickness (h): T = P × r / h. As pressure rises and the vein dilates, tension escalates, particularly since wall thickness does not proportionally increase, predisposing the varices to further expansion and potential rupture.^[19] Initial dilation begins in the submucosa, where the loose connective tissue allows outward expansion; over time, endothelial thinning occurs due to shear stress, accompanied by local inflammation that weakens the vessel wall and promotes rupture risk.^[2] Several factors accelerate variceal formation. A hepatic venous pressure gradient (HVPG) exceeding 12 mmHg is a critical threshold for variceal bleeding risk; approximately 90% of patients with cirrhosis develop varices within 10 years.^[2] Cytokine-mediated angiogenesis, particularly involving vascular endothelial growth factor (VEGF) upregulated in response to hypoxia, further drives collateral vessel proliferation and splanchnic hyperemia.^[19] Hypoxia-inducible factors (HIFs), such as HIF-1α, are activated in the hypoxic microenvironment of dilated veins, inducing pro-angiogenic genes like VEGF and exacerbating neovascularization.^[41]

Clinical Presentation

Asymptomatic Varices

Asymptomatic varices represent a silent phase of portal hypertension in patients with cirrhosis, where dilated esophageal or gastric veins are present but do not cause noticeable symptoms such as gastrointestinal bleeding or discomfort. These varices are typically detected incidentally during routine screening endoscopy in individuals with known liver disease, occurring in 30-60% of cirrhotic patients overall, with prevalence ranging from 30-40% in those with compensated cirrhosis to higher rates in decompensated cases.^[18]^[14] Small varices, defined as those less than 5 mm in diameter, are the most common form in this stage and carry a low annual bleeding risk of approximately 5%.^[2]^[3] Clinically, asymptomatic varices are associated with compensated cirrhosis, where liver function remains relatively preserved, and patients exhibit no signs of acute complications like hematemesis, melena, or anemia related to variceal hemorrhage. This phase underscores the importance of early detection through screening, as varices can progress silently without intervention; studies indicate that 10-12% of small varices enlarge to medium or large size annually in untreated patients.^[17] The absence of symptoms allows for proactive monitoring rather than urgent management, aligning with guidelines that emphasize surveillance to prevent progression to high-risk states. Monitoring for asymptomatic varices involves periodic endoscopy, with recommendations tailored to disease severity; for patients with Child-Pugh class A cirrhosis and small varices, surveillance every 1-2 years is advised, while those at lower risk may require endoscopy every 2-3 years.^[42] Screening via endoscopy, as detailed in diagnostic protocols, remains the gold standard for identifying these varices early and assessing their characteristics.^[42] This approach enables timely adjustments in care to mitigate potential future risks without overtreatment in the asymptomatic period.

Symptomatic Bleeding

Symptomatic bleeding from esophageal or gastric varices represents a life-threatening complication of portal hypertension, manifesting as acute upper gastrointestinal hemorrhage. The most common initial symptom is hematemesis, which appears as bright red blood in approximately 40% of cases or coffee-ground emesis in another 30-40%, reflecting slower bleeding or partial digestion of blood in the stomach. Melena, characterized by black, tarry stools due to digested blood, is observed in up to 60% of patients and often accompanies or follows hematemesis. In severe presentations, patients may experience syncope, weakness, or signs of hypovolemia, with hypotension and shock developing in 30-40% of cases, particularly when blood loss exceeds 30% of total volume. Physical examination reveals signs of hemodynamic instability and chronic liver disease exacerbation. Tachycardia is nearly universal in active bleeding, serving as an early indicator of volume depletion, while pallor reflects anemia from significant blood loss. Abdominal tenderness may occur due to distension from blood accumulation, and patients often exhibit stigmata of cirrhosis such as ascites, jaundice, or encephalopathy. Post-bleeding, liver function deteriorates, with the Child-Pugh score typically worsening by one or more classes, correlating with increased short-term mortality risk. Key endoscopic predictors of variceal rupture and bleeding severity include variceal size greater than 5 mm, which elevates the annual bleeding risk to 15-30% compared to 5% for smaller varices, and the presence of red wale markings—longitudinal dilated venules on the variceal surface—indicating impending hemorrhage. Advanced liver disease, specifically Child-Pugh class B or C, further stratifies risk, with annual bleeding rates of 20-40% in these groups due to higher portal pressure and impaired hemostasis. These features guide urgent intervention to mitigate rupture likelihood. Despite advances in care, variceal bleeding carries substantial morbidity, with in-hospital mortality ranging from 10-20% per episode, primarily from exsanguination, aspiration, or multiorgan failure in decompensated cirrhosis. Without prophylactic or therapeutic measures, rebleeding occurs in 60-70% of survivors within the first 1-2 years, though early recurrence within 6 weeks approaches 30-40% and is associated with 50% mortality if uncontrolled. Brief reference to acute management, such as vasoactive drugs and endoscopy, underscores the need for rapid stabilization to improve outcomes.

Diagnosis

Endoscopy

Upper gastrointestinal endoscopy, also known as esophagogastroduodenoscopy (EGD), serves as the gold standard for diagnosing esophageal varices due to its ability to provide direct visualization of the esophageal mucosa.^[43] This procedure allows for the assessment of varix size, location, and the presence of high-risk stigmata, such as cherry-red spots, which indicate impending rupture and elevated bleeding risk.^[44] During EGD, the endoscope is inserted through the mouth to examine the esophagus, stomach, and duodenum, enabling precise identification of varices typically located in the distal esophagus.^[45] Screening with EGD is recommended for all patients with cirrhosis to detect varices early, particularly in those with compensated advanced chronic liver disease.^[46] However, the Baveno VII consensus criteria, established in 2022 and refined in subsequent studies through 2025, incorporate non-invasive tools like transient elastography (liver stiffness measurement ≤15 kPa) and platelet count (≥150 × 10⁹/L) to rule out clinically significant portal hypertension and spare up to 20-30% of patients from unnecessary endoscopy.^[46]02565-6/abstract) For those not meeting sparing criteria, such as liver stiffness ≥20 kPa or low platelets, EGD is advised, with follow-up surveillance every 1-3 years depending on findings.^[46] Endoscopic findings are classified using systems like Paquet's grading (I-IV) based on varix size and form: grade I (small, straight varices), grade II (medium, straight), grade III (medium, tortuous), and grade IV (large, coiled or circumferential).^[47] Biopsy is rarely performed due to the risk of provoking bleeding or perforation, which occurs in less than 0.1% of diagnostic cases but can be higher in fragile variceal tissue.^[48] Complications of EGD in cirrhotic patients are infrequent but include sedation-related aspiration pneumonia in approximately 1-2% of cases, particularly in those with encephalopathy or ascites, and bleeding provocation in less than 1%.^[49] These risks are mitigated through careful patient selection and procedural monitoring. Complementary imaging techniques, such as transient elastography, support but do not replace endoscopic confirmation.^[46]

Imaging Techniques

Ultrasound with Doppler is a primary non-invasive imaging modality for assessing portal hypertension and detecting features associated with varices. It evaluates portal vein flow velocity, direction, and congestion index, as well as hepatic artery resistance index, to identify abnormalities indicative of portal hypertension. B-mode ultrasound can also detect splenomegaly, a common sign of portal hypertension, with spleen length greater than 13 cm suggesting increased risk.^[50]^[51]^[52] Transient elastography, such as FibroScan, provides liver stiffness measurement (LSM) to estimate hepatic fibrosis, which correlates with variceal risk in portal hypertension. LSM values greater than 25 kPa, particularly when combined with low platelet counts, indicate a high risk for high-risk gastroesophageal varices in patients with compensated cirrhosis, guiding the need for further evaluation. This technique is rapid, reproducible, and avoids radiation, making it suitable for screening.^[53]^[54] Computed tomography (CT) angiography and magnetic resonance imaging (MRI) angiography offer detailed visualization of portosystemic collaterals and varices. Contrast-enhanced CT depicts esophageal and gastric varices as enhancing tubular or serpiginous structures along the esophageal wall, with multiplanar reconstructions aiding in mapping collateral pathways. These modalities serve as surrogates for hepatic venous pressure gradient (HVPG) assessment by quantifying collateral extent and liver morphology, though they involve radiation (CT) or longer scan times (MRI).^[55]^[56]^[57] Endoscopic ultrasound (EUS) enhances assessment of gastric and ectopic varices by providing high-resolution imaging of their depth, size, and flow characteristics using Doppler. It distinguishes intramural from extramural varices and evaluates perforating veins, offering superior detail for periesophageal and perigastric structures compared to standard transabdominal ultrasound.^[58]^[59] As of 2025, artificial intelligence (AI)-enhanced CT has emerged for automated variceal detection, achieving sensitivities around 90% in identifying and grading esophageal varices through radiomics and deep learning models. These tools analyze contrast-enhanced images to predict variceal presence and bleeding risk noninvasively, improving efficiency in high-volume screening.^[60]^[61]

Prevention

Primary Prophylaxis

Primary prophylaxis refers to interventions aimed at preventing the first episode of variceal bleeding in patients with cirrhosis who have not experienced prior hemorrhage but are identified as at risk through endoscopic evaluation.^[46] The cornerstone of this approach is pharmacological therapy with non-selective beta-blockers (NSBBs), which decrease portal pressure by reducing cardiac output and causing splanchnic vasoconstriction, typically achieving a 15-20% reduction in hepatic venous pressure gradient (HVPG). Common agents include propranolol, administered at 20-40 mg twice daily, or carvedilol at 6.25-12.5 mg daily, with dosing titrated to achieve a target resting heart rate of 55-60 beats per minute while maintaining mean arterial pressure above 82 mmHg.^[62]^[63] NSBBs are indicated for patients with medium or large esophageal varices, or small varices accompanied by red wale signs—endoscopic features indicating increased bleeding risk, such as red spots or stripes on the variceal surface.^[64] Risk stratification via endoscopy identifies these high-risk features, guiding the need for prophylaxis.^[65] In such patients, NSBBs reduce the risk of first variceal bleed by 40-50% and improve overall survival.^[66]^[67] For patients intolerant to NSBBs due to side effects like hypotension or bradycardia, endoscopic band ligation (EBL) serves as an effective alternative, involving placement of rubber bands to obliterate varices in sessions repeated every 4-6 weeks until eradication is achieved.^[68] Recent guidelines, including the 2022 Baveno VII consensus and 2025 clinical reviews, recommend carvedilol as the preferred NSBB for primary prophylaxis, particularly in combination with other measures for Child-Pugh B or C cirrhosis to optimize portal pressure reduction and decompensation prevention.^[46]^[63]

Secondary Prophylaxis

Secondary prophylaxis aims to prevent recurrent bleeding in patients who have survived an initial episode of variceal hemorrhage, a critical intervention given the high risk of rebleeding, which can reach 60-70% within 1-2 years without treatment.^[69] The standard approach involves combined therapy using endoscopic band ligation (EBL) and non-selective beta-blockers (NSBBs), such as propranolol or nadolol, which has been shown to be superior to either modality alone in reducing rebleeding rates.^[70] This combination eradicates esophageal varices in approximately 70-90% of patients after 3-6 endoscopic sessions, typically performed at intervals of 2-4 weeks, and reduces the risk of rebleeding by about 60% compared to monotherapy.^[71]^[72] Indications for secondary prophylaxis encompass all patients with cirrhosis who have experienced variceal bleeding, with therapy recommended lifelong unless the patient undergoes liver transplantation, which resolves the underlying portal hypertension.^[73] In cases where NSBBs are contraindicated due to conditions such as refractory ascites, hypotension, or severe bradycardia, isosorbide mononitrate may serve as an alternative pharmacological agent, though it is less effective alone and should be combined with EBL when possible.^[74] Monitoring involves repeat endoscopy every 2-4 weeks during the eradication phase to assess progress and complications, transitioning to surveillance endoscopy every 3-6 months after variceal obliteration to detect recurrence, which occurs in 20-50% of cases.^[71] Hepatic venous pressure gradient (HVPG) measurement, if available, guides therapy optimization; an HVPG below 12 mmHg or a reduction of at least 20% from baseline predicts a low risk of rebleeding and favorable outcomes.^[69]

Treatment

Acute Management

The acute management of variceal bleeding prioritizes hemodynamic stabilization through initial resuscitation measures. Patients require immediate assessment and support of airway, breathing, and circulation, with intravenous access established for fluid resuscitation using crystalloids to maintain systolic blood pressure between 90 and 100 mmHg and heart rate below 100 beats per minute. Blood transfusions with packed red blood cells are administered to target a hemoglobin level of 7-8 g/dL, as restrictive strategies reduce rebleeding risk without increasing mortality. Coagulopathy is corrected judiciously with fresh frozen plasma or platelets only if clinically indicated, guided by viscoelastic testing to avoid over-transfusion.^[75]^[75]^[75]^[75] Vasoactive pharmacotherapy is initiated as soon as possible, ideally within 30 minutes of presentation, to reduce portal pressure and control bleeding. Preferred agents include terlipressin administered as a continuous infusion of 4-6 mg over 24 hours or octreotide with an initial bolus of 50 mcg intravenously followed by 50 mcg per hour infusion; these drugs decrease hepatic venous pressure gradient by approximately 15-20%, improving hemostasis rates. Therapy is continued for 2-5 days or at least 24-48 hours post-hemostasis.^[75]^[75]^[76]49673-9/fulltext) Airway protection is critical in cases of massive hematemesis or altered mental status, with endotracheal intubation recommended to prevent aspiration, particularly if oxygen saturation falls below 90%. Routine nasogastric tube placement is avoided due to rebleeding risk.^[75]^[75] Pre-endoscopy antibiotic prophylaxis with ceftriaxone 1 g intravenously daily for up to 5 days is standard in patients with advanced liver disease (e.g., Child-Pugh class B or C cirrhosis) to prevent bacterial infections, as the risk of spontaneous bacterial peritonitis approaches 20% without prophylaxis, and this intervention improves survival. This recommendation, reaffirmed in 2025 guidelines, applies particularly to those with advanced liver disease.^[75]^[75]01535-6/fulltext) Following stabilization, urgent endoscopic hemostasis is performed within 12 hours to achieve definitive control of the bleeding source.^[75]

Definitive Therapy

Definitive therapy for varices focuses on procedural interventions to achieve hemostasis and eradicate variceal sources following initial stabilization, typically after acute management with pharmacotherapy such as vasoactive agents.^[64] Endoscopic band ligation (EBL) serves as the primary intervention for esophageal varices, involving the placement of rubber bands to ligate and obliterate the varices during endoscopy. This technique achieves initial hemostasis in approximately 90% of actively bleeding cases and facilitates variceal eradication over multiple sessions, reducing rebleeding risk.^[64] For gastric varices, particularly those in the fundus, endoscopic injection of cyanoacrylate glue is the standard approach, providing initial hemostasis success rates of 80-90% by polymerizing upon contact with blood to seal the varix.^[77] This method promotes thrombosis and fibrosis, with obliteration rates reaching 86-97% after repeated injections, though it carries risks of glue embolization if not administered precisely.^[78] Balloon tamponade using the Sengstaken-Blakemore tube offers temporary mechanical compression of esophageal and gastric varices as a bridge to more definitive measures in uncontrolled bleeding scenarios. It controls acute hemorrhage in over 80% of cases initially, but efficacy is short-lived, with rebleeding occurring in up to 30-50% upon deflation, necessitating prompt transition to endoscopy or other interventions.^[79] Complications arise in approximately 10-20% of applications, including aspiration pneumonia, esophageal perforation, and mucosal ulceration, underscoring its role as a temporizing rather than curative strategy.^[80] For refractory variceal bleeding unresponsive to endoscopic and pharmacological efforts, or pre-emptively in high-risk patients (e.g., Child-Pugh C <14 or Child-Pugh B with active bleeding) who achieve initial hemostasis, transjugular intrahepatic portosystemic shunt (TIPS) placement via interventional radiology decompresses portal hypertension by creating a shunt between the portal and hepatic veins (pre-emptive within 72 hours, ideally <24 hours; salvage for refractory within hours). This procedure reduces the hepatic venous pressure gradient (HVPG) by more than 50% in the majority of patients, achieving hemostasis in 90-100% of cases and preventing rebleeding.^[81] With the use of covered stents, primary patency rates reach 80% at one year, though hepatic encephalopathy remains a notable adverse effect in 20-30% of recipients.^[82]^[83] Recent advancements as of 2025 have enhanced outcomes for gastric varices through endoscopic ultrasound (EUS)-guided coil embolization combined with cyanoacrylate glue injection, allowing precise targeting of the varix and feeding gastrorenal shunt under real-time imaging. This hybrid technique yields variceal obliteration rates of up to 95%, with lower rebleeding incidences (6-9%) compared to traditional methods, particularly in complex anatomical configurations.^[84] Technical success exceeds 95%, and it reduces the need for multiple sessions, marking a shift toward minimally invasive eradication.^[85]

Complications and Prognosis

Immediate Complications

Variceal bleeding can lead to hypovolemic shock in approximately 13% of cases, characterized by hemodynamic instability due to significant blood loss, which requires immediate resuscitation with fluids and blood products to prevent multi-organ failure.^[86] If untreated, hypovolemic shock associated with variceal hemorrhage carries a mortality rate of up to 40-50% in severe cases, primarily from exsanguination or secondary complications like acute kidney injury.^[87] Aspiration pneumonia can occur in patients with variceal bleeding, particularly those with severe hematemesis or using balloon tamponade, with reported rates up to 20% in high-risk subgroups, and it significantly increases the risk of prolonged hospitalization and ventilator support.^[88] Endoscopic interventions for variceal bleeding carry specific short-term risks. Following endoscopic band ligation (EBL) for esophageal varices, ulceration at the ligation site commonly develops in most patients as part of the healing process, with bleeding from these ulcers occurring in 3-10% of cases, typically presenting as minor bleeding that is managed conservatively with proton pump inhibitors and observation, though severe cases may necessitate repeat endoscopy.^[89] For gastric varices treated with cyanoacrylate glue injection, embolization complications arise in 2-5% of procedures, potentially leading to pulmonary or systemic migration of glue, resulting in embolism, infarction, or sepsis, which demands vigilant post-procedure monitoring including imaging if symptoms like chest pain or hypoxia occur.^[90] Bacterial infections are a frequent immediate sequela of variceal bleeding, driven by bacterial translocation from the gut due to portal hypertension and circulatory changes, culminating in sepsis in about 20% of patients within the first 48 hours despite prophylactic antibiotics.^[91] This translocation exacerbates systemic inflammation and coagulopathy, contributing to a twofold increase in short-term mortality if sepsis develops.^[92] Despite initial therapeutic interventions such as vasoactive drugs and endoscopy, rebleeding occurs in 20-30% of patients within the first 5 days, often due to incomplete hemostasis or clot disruption, and it is associated with a rebleeding-specific mortality of up to 30%.^[93] Early rebleeding is more common in those with advanced liver disease or active bleeding at index endoscopy, underscoring the need for intensive care unit monitoring during this critical period.^[94]

Long-term Outcomes

The long-term prognosis for patients with esophageal varices, primarily arising from portal hypertension in cirrhosis, is influenced by the underlying liver disease severity and implementation of prophylaxis. Prognosis is also assessed using the Child-Pugh classification, where class C patients have higher bleeding and mortality risks.^[4] With effective primary prophylaxis using non-selective beta-blockers or endoscopic variceal ligation, 1-year survival rates reach 80-85% in compensated cirrhosis, reflecting reduced bleeding risk and preserved liver function. In contrast, 5-year survival among cirrhotics with varices averages around 50%, as progressive decompensation leads to multi-organ failure in many cases.^[95]^[96] A Model for End-Stage Liver Disease (MELD) score exceeding 15 at diagnosis strongly predicts poorer outcomes, with increased risks of recurrent bleeding and mortality due to advanced fibrosis and portal pressure elevation.^[97] Variceal recurrence remains a significant challenge after initial eradication through endoscopic therapy. Following successful obliteration with band ligation combined with beta-blocker maintenance, varices recur in 20-30% of patients over 2-5 years, often necessitating surveillance endoscopy every 6-12 months to detect and retreat early regrowth. Liver transplantation markedly improves long-term survival, achieving 85-95% at 5 years in eligible cirrhotics by addressing the root cause of portal hypertension, though access is limited by donor availability and patient selection criteria.^[98]^[99] Quality of life in patients with varices is often compromised by ongoing psychological and physical burdens. Persistent fear of rebleeding contributes to heightened anxiety and depression, particularly in those with moderate-to-large varices, correlating with lower health-related quality-of-life scores on validated scales like the Chronic Liver Disease Questionnaire. Post-hemorrhage, nutritional deficits are common, stemming from acute blood loss, temporary nil-per-os status, and exacerbated malabsorption in cirrhosis, leading to sarcopenia and micronutrient deficiencies that further impair daily functioning.^[100]^[101] As of November 2025, insights from the Phase 2 NAVIGATE trial highlight potential advances in preventing variceal development. Belapectin, a galectin-3 inhibitor, reduced the incidence of new varices by approximately 23% at 36 months in patients with compensated metabolic dysfunction-associated steatohepatitis (MASH) cirrhosis and portal hypertension, compared to placebo, with sustained benefits in the per-protocol population (p<0.05 for key subgroups). This suggests a role for antifibrotic therapies in altering long-term disease trajectory, pending Phase 3 confirmation.^[102]
