대장의 Angiodysplasia 1례

Angiodysplasia is an important vascular lesion of the gastointestinal tract, located at the site of ectasia of intestinal submucosal veins and overlying mucosal capillaries. It is a major cause of morbidity from gastrointestinal bleeding in old age, but rather rare in children. Its cause is still unknown, though is mostly considered to be acquired as a result of a degenerative process associated with aging.
