Intestinal arteriovenous malformation (AVM) is an uncommon cause of gastrointestinal hemorrhage and is difficult to diagnose. Selective visceral angiography is essential to make the diagnosis and to localize the lesion. We treated two patients in whom AVMs of the small intestine were located by means of arteriography and intraoperative selective mesenteric venous pressure and PO2 measurements. The local venous return from an intestinal AVM is characterized by elevated venous pressure and PO2 levels compared with the venous drainage of adjacent normal intestine.
肠道动静脉畸形（AVM）是胃肠道出血的一种罕见病因，且难以诊断。选择性内脏血管造影对于做出诊断和确定病变位置至关重要。我们治疗了两名患者，通过动脉造影以及术中选择性肠系膜静脉压力和氧分压测量确定了小肠动静脉畸形的位置。与相邻正常肠段的静脉引流相比，肠道动静脉畸形的局部静脉回流表现为静脉压力和氧分压水平升高。
