Clinical Observation on Three Types of Upper Extremity Autogenous Arteriovenous Fistulas for Hemodialysis
Objective To analyze the differences、clinical characters and complications of three types of autogenous arteriovenous(AV) fistulas for hemodialysis, so as to provide guidance foroperation methods and their clinical application to hemodialysis. Methods 72 patients undergoing autogenous AV fistula procedures were divided into wrist AV fistula group(48 cases), snuf-box AVfistula group(14 cases) and elbow AV fistula group(10 cases) accordingto color doppler Ultrasonographic evaluation before operation. The operation time, mature time of AVF, complication data and diameter of AVF, blood flow for hemodialysis, venous diameter and influence on cardiac functionwere recorded. Results Operation time of the three types of operation showed no statistic difference(P>0.05). there is statistic difference in AVF mature time(F=36.423,P=0.000); The differences of complications data, diameter of AVF, blood flow for hemodialysis, venous diameter and influence on cardiac function in the three groups is not significant(P>0.05). Conclusion Color Doppler Ultrasonographic evaluation and clinical characters can provide optimal choice for AVF operation. Snuf-box AV fistula can be the first choice for patients with satisfactory vascular access, while elbow AV istula can be used for those with poor vascular access or with forearm fistula failure.
