Two cases of recurrent bleeding from the gastro-intestinal tract are described. The initial diagnosis and the identification of the lesions at laparotomy were difficult problems. In both cases the bleeding was due to a vascular lesion of the small bowel, referred to as angiodysplasia. The lesions were detected before operation by selective angiography and identified at laparotomy by a preoperative and an intraoperative injection of a vital stain through the catheter into the feeding vessels.
本文描述了两例胃肠道反复出血的病例。初次诊断以及剖腹手术时对病变的识别是难题。两例出血均由小肠血管病变所致，这种病变被称为血管发育异常。术前通过选择性血管造影检测到病变，并在剖腹手术时通过术前及术中经导管向供血血管注射活性染料来识别病变。
