摘要目的 探讨上臂人工血管移植透析内瘘的建立方法及临床应用价值. 方法参考国外文献设计了腋动脉与腋静脉建立上臂U形人工血管移植内瘘,腋动脉与肘窝贵要静脉作上臂直桥式内痿,肱动脉与腋窝腋静脉制作上臂直桥式内瘘,采用3种方法为20例长期血液透析患者建立了上臂人工血管移植透析通路.患者男9例,女11例.年龄37～64岁,平均54岁.透析时间2～15年.结果 20例手术操作均一次成功,术后6～8周用于临床穿刺透析,透析血流量220～300ml/min,血液再循环在正常范围,完全满足长期血液透析治疗的需要.结论 当前臂或上臂由于各种原因不能制作自体动静脉内瘘和前臂血管移植内瘘时,上臂腋窝制作人工血管移植血管内瘘是行之有效的方法.

abstractsObjective To investigate the application of expanded p01ytetrafluoroethylene(ePTFE)grafts in upper arm to build arteriovenous aCCeSS for hemodialysis. Methods ePTFE graft vascular access was built in the upper arm in 20 uremia patients.Three operation strategies were applied according to the reference,including loop grafts connected axillary artery and axillary vein,straight graft connected axillary artery and elbow basilic vein,and bridge connected elbow brachial artery and axillary vein. Results Twenty operations were successful and after 6-8 weeks the fistula of all cases were used in hemodialysis.The blood flows were 220-300 ml/min without re-circulation found.Conclusion ePTFE graft arteriovenous vascular access in the upper arm could be an alternative for hemodialysis patients who are difficult to build native arteriovenous fistula.
