Gastronintestinal vascular dysplasia as a cause of persistently recurring melaena is reported in two patients with von Willebrand's disease. Colonic wall vasculature was affected in one patient, the abnormality being demonstrated both radiologically and at operative hemicolectomy undertaken to control bleeding. Abnormalities in the vasculature of the duodenal and jejunal walls were found in the second patient at operation and necropsy, though not demonstrated by angiography.
两名患有血管性血友病的患者被报告患有胃肠道血管发育异常，这是持续性反复黑便的一个原因。一名患者的结肠壁血管系统受到影响，通过放射学检查以及为控制出血而进行的手术半结肠切除术均证实了这种异常。在第二名患者的手术和尸检中发现十二指肠和空肠壁血管系统存在异常，尽管血管造影未显示出这种异常。
