摘　　要：目的探讨肘部动静脉内瘘的手术方法及在血液透析中的应用。方法 2006年5月至2012年5月完成肘部动静脉内瘘术22例。采用肘关节横纹下2～3 cm横切口,其中桡动脉与肘正中静脉端侧吻合17例,侧侧吻合2例,2例采用头静脉与肱动脉进行侧侧吻合,1例采用贵要静脉与肱动脉进行侧侧吻合。所有患者围手术期均采用彩色多普勒进行动态观察评估。结果平均手术时间为(120±16.15)min。在手术中无外科并发症。术后内瘘均立即通畅,前臂可触及动脉搏动。平均内瘘成熟时间为(41±8.15)d。术后早期1例因动脉搏动欠佳出现血栓阻塞。2例出现短暂性前臂局部水肿。其余患者未出现盗血综合征,动脉瘤,栓塞,感染,出血等并发症。结论肘部动静脉内瘘是维持血液透析患者一个理想和安全的选择。手术方法应根据患者肘部血管的解剖学特点进行选择。Objective To investigate the use of vascular access in maintenance hemodialysis and the complications of elbow arteriovenous fistulas （AVF）. Methods From our database of consecutive vascular access operations, we reviewed 22 patients from May 2006 to May 2012 for all elbow arteriovenous fistulas. A transverse skin incision was made 2-3cm below the elbow crease. Radial artery and brachial artery were used as the in-flow conduit in 19 patitens and 3 patients respectively. The median cubital vein was anastomosed to the radial artery in end-to-side fashion in 17 cases and side-to-side fashion in 2 cases, the cephalic vein and the basilic vein were anastomosed to the brachial artery in side-to-side fashion in 2 cases and 1 case respectively. All patients were evaluated with preoperative ultrasound imaging by the operating surgeon. Results Mean operative time was 120±16.15min. There were no major intraoperative complications. Immediate patency and a palpable distal radial pulse were presented in all the patients. Mean time to fistula maturation was 41±8.15 days. Early fistula failure was seen in one patient because of thrombosis. Early transient ann edema were seen in two patients. No patient developed a vascular steal syndrome, pseudoaneurysm, infection and bleeding during the perioperative time. Conclusions An elbow AVF is a reasonable and safe alternative for maintenance hemodialysis access when a radiocephalic AVF is not possible. There are various valid options from which to choose to best accommodate each patient＇s antecubital anatomy.
