Variceal Bleeding

Variceal bleeding refers to the occurrence of bleeding from enlarged and fragile blood vessels called varices. Varices are most commonly found in the esophagus and stomach, but they can also occur in other parts of the gastrointestinal (GI) tract, such as the rectum. Varices develop when there is increased pressure in the portal vein, the large vein that carries blood from the digestive organs to the liver. This increased pressure can result from liver cirrhosis or other conditions that cause portal hypertension.

The most common cause of variceal bleeding is cirrhosis of the liver. In cirrhosis, the liver undergoes extensive scarring and becomes nodular, disrupting normal blood flow within the liver and leading to increased portal vein pressure. However, other conditions that cause portal hypertension, such as portal vein thrombosis, Budd-Chiari syndrome, and schistosomiasis, can also lead to varices and variceal bleeding.


Aortic dissections usually occur due to weaknesses in the inner layer of the aortic wall. Factors that can contribute to the development of aortic dissections include:

  1. High blood pressure (hypertension): This is the most common risk factor for aortic dissection.
  1. Atherosclerosis: The buildup of plaque within the arteries can weaken the aortic wall.
  1. Connective tissue disorders: Certain genetic conditions, such as Marfan syndrome and Ehlers-Danlossyndrome, can predispose individuals to aortic dissections.
  1. Trauma: Severe blunt trauma to the chest or aortic region can cause an aortic dissection, although this is less common.
  1. Pregnancy: Aortic dissections can rarely occur during pregnancy or childbirth.

Symptoms of variceal bleeding can vary depending on the severity of the bleed but may include:

 1. Vomiting of bright red blood or “coffee ground” material (partially digested blood).

2. Passage of black, tarry stools (melena) due to the presence of digested blood in the stool.

3. Low blood pressure and rapid heart rate due to blood loss.

4. Weakness, lightheadedness, or fainting.

Variceal bleeding can be life-threatening and requires urgent medical attention.

Diagnosis and Treatment

Diagnosis of variceal bleeding is typically based on clinical presentation and confirmed by endoscopy, where a flexible tube with a camera (endoscope) is inserted into the esophagus and stomach to visualize and identify the varices.

Treatment for variceal bleeding aims to stop the bleeding, prevent rebleeding, and manage the underlying cause of portal hypertension. Treatment options may include:

  1. Endoscopic therapy: Endoscopy can be used to directly treat bleeding varices. Techniques such as band ligation or sclerotherapy can be used to stop active bleeding and prevent future bleeding episodes.
  1. Medications: Vasopressin analogs, somatostatin analogs, or their derivatives may be administered to constrict blood vessels and reduce bleeding.
  1. Transjugular intrahepatic portosystemic shunt (TIPSS): This is a procedure where a shunt is placed to connect the portal vein to a hepatic vein, bypassing the liver and reducing portal vein pressure.
  1. Balloon tamponade: In severe cases, a balloon may be placed in the esophagus to compress bleeding varices temporarily.
  1. Liver transplantation: In cases of advanced liver disease, liver transplantation may be considered as a definitive treatment option.

Preventing variceal bleeding involves managing the underlying cause of portal hypertension, such as treating liver cirrhosis and other liver diseases. Additionally, lifestyle modifications such as avoiding alcohol, following a low-sodium diet, and taking medications as prescribed can help reduce the risk of complications.


If you suspect variceal bleeding or experience symptoms of severe GI bleeding, seek immediate medical attention. Early diagnosis and appropriate intervention can significantly improve outcomes and reduce the risk of complications.
