Malformacja naczyniowa jelita czczego przyczyną krwotoku z przewodu pokarmowego – opis przypadku

Abstract Vascular malformation is a rare cause of bleeding from the lower gastrointestinal tract. We present a case of 16-year-old patient with a hemorrhage from the gastrointestinal tract, which led to the life-threatening anemia. Gastroduodenoscopy and colonoscopy were performed and did not locate a bleeding site. Consecutively, an exploratory laparotomy did not locate the pathology either. A bleeding site was visualized by computed tomography angiography (CTA) of the abdomen. Relaparotomy was performed and the 4-centimeter part of the intestine and a small jejunal vascular malformation were histopathologically revealed.
