Colonic angiodysplasia. Clinical, endoscopic, arteriographic signs and histopathological correlations.
The main clinical, endoscopic and radiographic findings in thirty documented cases of colonic angiodysplasia or vascular ectasia are described. We emphasise the association with colonic diverticulosis and cardiovascular pathology, describe the histological changes, summarize the present physiopathological hypothesis, and consider the various therapeutic approaches.
