Angiodysplasia is the most common vascular lesion of the gastrointestinal tract, and this condition may be asymptomatic, or it may cause gastrointestinal (GI) bleeding.
In the small bowel, 30 to 40% of bleeding is caused by abnormal blood vessels in the wall of the small bowel. These abnormal blood vessels have many names, including angioectasias, angiodysplasias, or arteriovenous malformations (AVMs).he small bowel (or small intestine) is the longest portion of the gastrointestinal (GI) tract. It is called small because it is thin or narrow compared with the large bowel (also known as the colon), but it is much longer than the large bowel (14 feet on average).
