目的：评价选择性血管造影对血管畸形所致消化道出血的定位和定性诊断意义，以及血管内栓塞治疗的结果。材料和方法：１１例不明原因的消化道出血患者通过血管造影诊断为胃肠血管畸形。本组年龄范围在１５～７０岁之间，平均年龄４８岁，均有反复消化道出血病史，出血量较小时，每次３００～５００ｍｌ之间，较大时在１２００～１５００之间，最大量估计达３０００ｍｌ。血管造影顺序一般按肠系膜下动脉－肠系膜上动脉－腹腔动脉方式。血管栓塞剂选用钢圈、明胶海绵、ＰＶＡ微粒三种。结果：在１１例胃肠血管畸形中，由腹腔动脉干及分支合并肠系膜上动脉干供血的４例，由肠系膜上动脉分支供血的７例；发生在胃及十二指肠圈附近的８例，而发生于空肠下段回结肠段的３例。除５例接受手术治疗外，６例行血管内栓塞治疗。结论：选择性血管造影对于胃肠血管畸形可提供直接的影像诊断依据；血管内栓塞术是值得推荐的胃肠血管畸形首选治疗方法。
Objective: To evaluate the significance of selective angiography in the localization and qualitative diagnosis of gastrointestinal hemorrhage caused by vascular malformation, and the results of endovascular embolization. Materials and Methods: Eleven patients with gastrointestinal bleeding of unknown origin were diagnosed as gastrointestinal vascular malformations by angiography. The age range of 15 to 70 years old, with an average age of 48 years old, have a history of repeated gastrointestinal bleeding, bleeding is small, each time between 300 ~ 500ml, larger between 1200 ~ 1500, the largest Estimated up to 3000ml. Angiography sequence generally according to the superior mesenteric artery - superior mesenteric artery - celiac artery. Vascular embolic agent selection steel ring, gelatin sponge, PVA particles three. RESULTS: Of the 11 cases of gastrointestinal vascular malformations, 4 were from the celiac trunk and the branch superior mesenteric artery, 7 were from the superior mesenteric artery, and 8 were from the stomach and the duodenum , And occurred in the lower jejunum colon segment in 3 cases. In addition to 5 cases of surgical treatment, 6 cases of endovascular embolization. Conclusion: Selective angiography can provide a direct diagnostic basis for gastrointestinal vascular malformations. Endovascular embolization is the preferred treatment for gastrointestinal vascular malformations.
