Intestinal angiodysplasia as a cause of severe intestinal hemorrhage--report of 4 cases
Angiodysplasia of the small intestine alone cannot be differentiated histologically from hereditary hemorrhagic telangiectasia (Morbus Rendu-Osler-Weber). Isolated localisation in the small intestine is rare and requires surgery in the event of massive bleeding. Four cases of bleeding from angiodysplasias of the small intestine in patients having undergone surgery at our institution over a ten-year period are presented. In three patients the particular intestine was resected. Two of these patients had an uneventful follow-up of even and ten years, one patient relapsed and was rehospitalized for surgical treatment. The fourth patient, who showed angiodysplasias scattered over the entire small intestine, had no further bleeding over a three-year period after transmural ligations of the lesions found by intraoperative endoscopical diaphany.
