【摘要】 目的 探讨空回肠血管畸形出血部位的术中定位方法。方法 1995年12月至2005年11月，复旦大学中山医院对16例空回肠血管畸形病人，经选择性肠系膜血管造影证实具体出血动脉后，再进一步对出血分支动脉行超选择性插管，置入导引钢丝作为术中定位标记。结果 肠血管畸形位于空肠9例、回肠6例、空肠加结肠1例。手术时均顺利找到标记物并切除病变肠管，从而获得满意疗效。结论 经选择性肠系膜血管造影明确畸形的肠血管后，置入标记物作为术中寻找病变部位的定位标记，是一种非常有效的方法。

Mesenteric angiographic selective location of jejunoileal vascular malformations with combined use of the guide wire LING Yue-xin*, TONG Sai-xiong, AI Zhi-long, et al. *Department of General Surgery, Zhongshan Hospital, Fudan University, Shanghai 200032, China Corresponding auther: TONG Sai-xing, E-mial: sxtong@ zshospital.net Abstract Objective To study the intraoperative location of jejunoileal vascular malformations. Methods 16 cases of jejunoileal vascular malformation were diagnosed by mesenteric selective angiography. Subsequent superselective catheterization of a bleeding branch was performed. The guide wire was placed as a marker for intraoperative location. Results 9 cases of intestinal vascular malformation were located in the jejunum, 6 in the ileum, 1 in the jejunum and colon. At operation, the guide wire could easily be found and subsequent surgical resection performed successfully. Conclusion Placing the guide wire as a marker by angiographic techniques is quite useful in locating intraoperatively the exact bleeding site of jejunoileal vascular malformation.
