介绍一例92岁高令女病人,两年来发生四次短期下消化道出血。作钡餐、钡灌肠造影未见异常。作纤维结肠镜检查,只发现回盲瓣上有一糜烂斑,活检病理报告为炎症。作上肠系膜动脉造影,发现回盲部动脉影紊乱成团,静脉早期显影;作回结肠动脉超选择性造影,更清楚地见到该动脉分支扭曲、扩张,动脉相晚期就清楚见到引流静脉,诊为回结肠动脉发育不良。因高龄,又有心脏病史、脑血管意外史,当时还有房颤情况,不宜手术治疗。采用聚乙烯醇经导管栓塞发育不良的回结肠动脉。栓塞前24小时清理肠道并口服抗菌素,为万一并发肠坏死需手术切除作好准备。把6.5F聚乙烯导管经上肠系膜动脉引入回结肠动脉的两个分支中,将经过压缩处理的聚乙烯醇分别栓入血管中,随后作造影,证实血管分支堵塞成 An example is a 92-year-old woman with a high order who has had four short-term lower gastrointestinal bleeding in two years. Barium meal, barium enema no abnormalities. For fiber colonoscopy, only found on the ileocecal valve has a erosion spot, biopsy reported as inflammation. For the superior mesenteric artery angiography, found ileocecal artery chaos into a group, early visualization of the vein; for the superior mesenteric artery angiography, more clearly see the branch of the artery distorted, dilated, clearly see the late arteries of the drainage veins , Diagnosed as back to the colon artery dysplasia. Due to old age, another heart history, history of cerebrovascular accidents, there was atrial fibrillation, not surgical treatment. Polyvinyl alcohol catheter embolism dysplastic ileocolic artery. The intestine was cleared 24 hours prior to embolization and oral antibiotics were prepared for surgical resection in case of intestinal necrosis. The 6.5F polyethylene catheter was introduced through the superior mesenteric artery back into the two branches of the colonic artery, the polyvinyl alcohol after compression were respectively inserted into the blood vessel, followed by contrast, confirmed that the blood vessel blockage into
