摘　　要：目的探讨切割球囊治疗高压球囊扩张失败的狭窄闭塞人工血管内瘘(AVG)的有效性和安全性。方法回顾性分析2017年1月至2019年2月广州医科大学附属第二医院血管外科高压球囊扩张狭窄闭塞AVG病变失败(残留狭窄>50%)后续采用切割球囊治疗的32例患者的病例资料,统计分析狭窄闭塞位置,术后即时、3、6、12个月通畅率及技术并发症情况。结果共32例患者,其中主要狭窄病变位于人工血管静脉吻合口27例(84.38%),静脉吻合口合并人工血管穿刺点2例(6.25%),静脉吻合口合并动脉吻合口2例(6.25%),头静脉弓1例(3.13%)。切割联合高压球囊治疗成功30例,技术成功率93.75%(30/32),另2例(6.25%,静脉吻合口端闭塞)经切割、高压球囊扩张后使用覆膜支架。切割球囊破裂发生2例(6.25%),无切割球囊相关性血肿或动脉瘤发生。随访(9.4±0.8)个月,治疗后3、6、12个月初始通畅率分别为90.63%(29/32)、59.38%(19/32)、28.13%(9/32),辅助通畅率分别为100.00%(32/32)、84.38%(27/32)、65.63%(21/32)。结论高压球囊开通AVG狭窄闭塞病变失败可采用切割球囊提高内瘘寿命,其3、6个月通畅率、安全性较高,但中长期通畅率的进一步提高有赖于新技术、新材料的应用。Objective To investigate the efficacy and safety of percutaneous cutting balloon(PCB)angioplasty for the treatment of hemodialysis arteriovenous graft(AVG)stenosis or occlusion after to high-pressure balloon angioplasty failure.Methods From January 2017 to February 2019,32 cases of AVGs stenosis or occlusion treated with PCB in our department after failure of high-pressure balloon angioplasty(residual stenosis>50%)were enrolled,positions and numbers of stenosis,and immediate,3,6 and 12-month patency rate were recorded.Results A total of 32 patients,the main lesions were located at the graft-to-vein anastomosis in 27 cases(84.38%),puncture points of artificial graft in 2 cases(6.25%),graft-to-artery anastomosis in 2 cases(6.25%),and arch of cephalic vein in 1 case(3.13%).Thirty cases were successfully treated by cutting balloon combined with high-pressure balloon,the technical success rate was 93.75%(30/32),other 2 cases(6.25%)were combined with covered stent implantation.There were 2 cases(6.25%)of cutting balloon rupture,without hematoma or aneurysm formation.The follow-up time was(9.4±0.8)months.The primary patency rate was 90.63%(29/32)at 3 months,59.38%(19/32)at 6 months and 28.13%(9/32)at 12 months after treatment.The patency rate of 3,6 and 12 months were 100%(32/32),84.38%(27/32),65.63%(21/32),respectively.Conclusion PCB can improve the service life of AVGs after fuilure of high-pressure balloon angioplasty.The patency rate and safety are relatively higher in 3 and 6 months,but further improvement mid-and long-term patency requires new technologies and materials.
