移植物动脉-动脉通路在血液透析中的应用效果

Application of arterio-arterial grafts access in hemodialysis

前瞻性纳入2021年3月至2023年12月于北京市海淀医院行移植物动脉-动脉通路(AAG)的13例患者。男6例,女7例,年龄(59±13)岁,透析龄4.0(1.8,10.0)年。建立“弓”型AAG 9例,“α”型AAG 4例,随访时间10(7,16)个月。术后3、6、12个月初级和次级通畅率分别为92.3%和100%、81.8%和90.9%、57.1%和57.1%。2例次发生狭窄;5例次发生血栓形成;2例患者发生感染。可见,AAG手术操作简单,创伤小,长期通畅率较高,可作为无法建立常规透析通路患者新的血管通路类型。

Patients who underwent arterio-arterial graft(AAG)surgery at Beijing Haidian Hospital from March 2021 to December 2023 were prospectively included.A total of 13 cases(6 males and 7 females)aged(59±13)years were collected,with a dialysis history of 4.0(1.8,10.0)years.Nine cases of"bow"-type AAG and 4 cases of"α"-type AAG were established.The follow-up time was 10(7,16)months.The primary patency and secondary patency rates at 3,6 and 12 months after surgery were 92.3%and 100%,81.8%and 90.9%,57.1%and 57.1%,respectively.Stenosis,thrombosis and infection occurred in 2,5 and 2 cases,respectively.The current study indicates that AAG surgery is simple,minimally invasive,and has a high long-term patency rate.It can be used as a new type of vascular access for patients who fail to establish conventional dialysis access.
