Twelve consecutive patients presenting with unexplained recurrent gastrointestinal bleeding were investigated by selective visceral angiography. A cause for the bleeding was shown in all 12 cases, and in eight the lesion responsible was diagnosed radiologically as an area of angiodysplasia. Abnormal areas were pinpointed by fluoroscopy and examination of the resected bowel with a dissecting microscope after injecting the vessels with barium. Histologically these areas had various microvascular abnormalities. Angiodysplasia is a useful descriptive radiological term, but does not seem to represent a single pathological entity.
对12例不明原因复发性胃肠道出血的连续患者进行了选择性内脏血管造影检查。所有12例均显示出出血原因，其中8例经放射学诊断，出血病变为血管发育异常区域。通过荧光透视定位异常区域，并在向血管内注入钡剂后，用解剖显微镜检查切除的肠段。组织学上，这些区域有各种微血管异常。血管发育异常是一个有用的描述性放射学术语，但似乎并不代表单一的病理实体。
