Overview
In medicine (gastroenterology), angiodysplasia is a small, acquired vascular malformation of the gut. It is a common cause of otherwise unexplained gastrointestinal bleeding and anemia, especially after sixth decade of life. Lesions are often multiple, and frequently involve the cecum or ascending colon, although they can occur at other places. Treatment may be with endoscopic interventions, medication, or occasionally surgery.
Historical Perspective
The first case of angiodysplasia was described in a letter to the London Medical Gazette by Phillips as a vascular abnormality causing bleeding from the large bowel in 1839. However, the term "Angiodysplasia" was coined by Galdabini in 1974. Due to the unknown etiology of these lesions, multiple terms have been used, like arteriovenous malformation, telangiectasia, angioma, and hemangioma.
