目的评估下肢人工血管动静脉内瘘(arteriovenous graft，AVG)在终末期肾脏病患者中应用的效果及安全性。方法回顾性分析在重庆医科大学附属第一医院血管外科建立下肢人工血管动静脉内瘘作为血管通路的11 例患者的临床病例资料。结果手术操作均1 次成功，患者在术后4～8 周开始使用人工血管，初级通畅率为100%，血流量可达200～360ml/min。术后随访3～19 个月，期间未发现人工血管感染等不良并发症。结论下肢人工血管动静脉内瘘作为在上肢血管资源耗竭后的终末期肾脏病患者中的选择是可行的。

Objective To assess the clinical application of arteriovenous grafts in lower extremities in end-stage renal disease patients. Methods The clinical data of 11 patients treated with arteriovenous grafts in lower extremities for hemodialysis vascular access in our hospital were analyzed retrospectively. Results All operations were successfully performed, and all of the fistula were used for blood access in hemodialysis after the operation for 4～8 weeks. Primary patency rate was 100%, and the blood flow ranged from 200 ml/ min to 360ml/min. Patients had no postoperative complications such as graft infection during the follow-up period of 3～19 months. Conclusions Lower extremity arteriovenous graft is feasible for end-stage renal disease patients with exhausted arm access sites.
