摘要： 目的探讨覆膜支架治疗人造血管动静脉内瘘(arteriovenous graft，AVG)狭窄的疗效。方法回顾性分析在重庆医科大学附属第一医院血管外科使用覆膜支架治疗AVG 狭窄患者的临床病例资料。结果纳入患者6 例，在置入覆膜支架前平均经过2.7 次皮腔内血管成型术治疗。4 例为吻合口后狭窄，2 例为静脉流出道狭窄。术后平均随访时间(13.0±3.3)个月，术后3、6、12 个月初级通畅率分别为83%，67%和40%，次级通畅率均为100%。结论覆膜支架治疗AVG 短期通畅率较高，且在处理人工血管其他并发症上也有优势。

Abstract: Objective To investigate the treatment efficacy of covered stent for arteriovenous graft (AVG) stenosis in hemodialysis patients. Methods The clinical data of AVG stenosis treated by covered stent in our center were retrospectively analyzed. Results This method was used in 6 cases. Before stent placement, they had received average 2.7 times of percutaneous transluminal angioplasty. The stenosis located at the veins near anastomosis in 4 cases and at the venous outflow tracts in 2 cases. They were followed up for 13±3.3 months. The primary patency rates at 3, 6 and 12 months were 83%, 67% and 40%, and the secondary
patency rates were 100%. Conclusion Short-term patency rate of covered stent treatment for AVG stenosis is satisfactory. Covered stent also has the advantages of treating other AVG complications.
