The snuffbox arteriovenous fistula for vascular access:28 cases report

Objective To determine the establishment,patency rate,complication and applicability of internal arteriovenous fistula at anatomical snuff-box.Methods Twenty-eight chronic renalfailure patients have been established internal arteriovenous fistula at anatomical snuff-box below the carpal joint since July,2007,end-to-side anastomosis between cephalic vein and the dorsal branch of arteria radialis,for clinical hemodialysis 6 weeks later.Results Twenty-eight patients were all operated for first time,the instant pantency rate during the operation was 100%.3 patients were operated again on standard side for vascular occlusion,and 2 patients for insufficient blood flow during hemodialysis 6 weeks later.28 patients had the follow-up after operation from 2 months to 4 years.The fistula worked well with less complications,1 year pantency is 75%.Conclusion The snuffbox AV fistula enlarges the puncture range,and preserves the proximal vessels.It can be the first choice of blood access for chronic hemodialysis patients who have good vessel condition.
