**Question:** True regarding gastric antral vascular ectasia (GAVE)

A. GAVE is a common cause of gastrointestinal bleeding in cirrhosis patients
B. GAVE is associated with portal hypertension
C. GAVE is a rare disorder affecting only the esophagus
D. GAVE is always associated with an underlying malignancy

**Correct Answer:** B. GAVE is associated with portal hypertension

**Core Concept:** Gastric antral vascular ectasia (GAVE) is a condition characterized by abnormal dilation and tortuosity of the vessels in the antrum of the stomach. It is a rare clinical entity, but when present, it is often associated with underlying conditions that lead to portal hypertension.

**Why the Correct Answer is Right:** GAVE is typically associated with portal hypertension, a condition characterized by increased vascular resistance in the portal vein system. This condition leads to dilation and ectasia (abnormal enlargement and tortuosity) of the vessels in the antrum of the stomach, giving rise to the clinical presentation of GAVE.

**Why Each Wrong Option is Incorrect:**

A. GAVE is not a common cause of gastrointestinal bleeding in cirrhosis patients. While portal hypertension is a common cause of gastrointestinal bleeding in cirrhosis patients, GAVE itself is not the most common reason for gastrointestinal bleeding in this group. Other causes, such as esophageal varices, gastric varices, and Mallory-Weiss tears, are more common.

C. GAVE is a rare disorder affecting only the esophagus. As stated earlier, GAVE is a rare condition affecting the antrum of the stomach, not the esophagus.

D. GAVE is always associated with an underlying malignancy. While GAVE can be associated with various conditions, it is not always associated with malignancy. Other causes of GAVE include autoimmune disorders, connective tissue diseases, and liver disease (particularly cirrhosis and portal hypertension).

**Clinical Pearl:** Understanding the association between GAVE and portal hypertension is crucial, as it helps guide appropriate diagnostic and therapeutic strategies. In cases where GAVE is suspected, further evaluation for portal hypertension and its underlying causes is essential.
