50 Cases of Balloon Dilatation of Internal Arteriovenous Fistula Clinical Effect Evalution

Objective:In order to evaluate the operation methods and the clinical effect of the forearm internal arteriovenous fistula for blood purification.Methods:From July 2005 to January 2012,we had summarized 50 patients with urinemia who received the forearm internal arteriovenous fistula by the catheter in the Department of Nephrology of the first affiliated hospital of Ji-nan University.We usually choose the nondominant arm to operate,after the distal of the artery and vein were ligated,we inserted the catheter into the proximal vessels to dilate the cephalic vein and/or the radial artery.We performed an end-to-side anastomosis with a 7-0monofilament suture.Results:We examined the AVF by palpation and auscultation just after operation、1、2、3 hour and continuous 7 days postoperatively.The mean length of follow-up was 60 months,The patency rate was over 90%,and 30 patients who received blood purification have used the autogenous radial-cephalic internal arteriovenous fistula over 3 years,The AVF blood flow was larger than 250 ml/min during blood purification.Conclusion:The autogenous radial-cephalic internal arteriovenous fistula operation by the catheter have a high achievement ratio,and the patency rate was 95%.The method is successful in overcoming the stenosis of the cephalic vein and/or the radial artery,and the patients gain a quit good clinical effect.
