下肢人工血管动静脉内瘘的远期通畅分析

Analysis of long-term patency in hemodialysis patients with lower extremity arteriovenous grafts

目的评价下肢人工血管动静脉内瘘(arteriovenous grafts,AVG)的远期通畅情况。方法回顾性分析重庆医科大学附属第一医院金山血液透析通路中心2015年1月1日~2017年10月1日新建AVG患者临床资料。结果成功随访19例,6月、12月、24月的初级通畅率分别为79%、63%、31%,辅助初级通畅率分别为100%、95%、69%,次级通畅率为100%、100%、100%。影响通畅的事件包括:狭窄、血栓、假性动脉瘤。结论下肢AVG通畅率较低,但仍可作为上肢血管资源耗竭患者的血液透析通路。

Objective To analyze the long-term patency in hemodialysis patients with lower extremity arteriovenous grafts(AVG).Method This was a retrospective analysis including 19 lower extremity AVGs constructed during January 2015 to October 2017.Their primary,assisted primary and secondary patency rates were calculated.The events leading to patency failure were analyzed.The stenosis sites were described.Results A total of 19 patients were enrolled in this study.At the 6th month,12th month and 24th months,the primary patency rates were 79%,63%and 31%respectively,the assisted primary patency rates were 100%,95%and 69%respectively,and the secondary patency rates were all 100%.Conclusion Lower extremity AVG had lower patency rate,but it still can be optional in patients with unusable upper extremity vein.
