Gastrointestinal Angiodysplasia in Patients with Chronic Kidney Disease and Hepatic Cirrhosis

Autors

Angiodysplasia (AD), gastric antral vascular ectasia (GAVE or watermelon stomach), radiation-induced vascular ectasia and Dieulafoy’s lesions are considered sporadic lesions and they can induce gastrointestinal bleeding (1). AD is the most common vascular abnormality of the gastrointestinal tract, probably the most common cause of recurrent gastrointestinal hemorrhage in patients with renal failure (2) and an important cause of erythropoiet-inresistant anaemia in dialyzed patients. Angiodysplasia injuries developed in the gastric antrum were first described in 1953 and named GAVE, being characterized as submucosal capillary dilatation and fibromuscular hyperplasia (3).
