Studies On Using Small Caliber Cephalic Vein To Construct The Autogenous Radial-cephalic Hemodialysis Access

Object: To discuss the patency of the autogenous radial-cephalic hemodialysis access using small caliber cephalic vein.Methods: From August 2005 to January 2008, 67 patients with uremia received operation of radial-cephalic hemodialysis access in the Qingpu Zhongshan Hospital of Fudan University. All patients were the first time to establish autogenous arteriovenous fistula(AVF). The experimental group(EG) consisted of 40 patients who use the Fogarty catheter.The fistula were placed only for veins 2.5mm) make up control group(CG).They received the traditional operation. Follow up the patency rates and complication rates of the fistula after procedure.Results: Follow up the information of all the 67 patients completely. The shortest follow-up was 2 month and the longest was 31 month. Mean follow-up was 18 months. 5 AVFs were failure in EG and 4 in CG. 58 patients had received hemodialysis using radial-cephalic access. Primary and secondary patency rates were 64% and 72% at 12 months for EG and 60% and 76% at 12 months for CG, respectively. The patients in the two groups had different complication rates(12.5% vs7.4%), P<0.05.Conclusions: The method is convenience to overcome the stenosis of the vessels.Partial patients who have small caliber cephalic vein can get ideal access. The longterm effects need to be observed further more.
