Excellent performance of one-stage brachial–basilic arteriovenous fistula

Abstract

Background. According to the National Kidney Foundation-Dialysis Outcomes Quality Initiative (NKF-DOQI) and the European Guidelines, the first and second choice for vascular access for haemodialysis are the radial–cephalic and brachial–cephalic arteriovenous fistula (AVF). Autogenous fistulas have a longer functional lifetime, less thrombotic complications and a lower infection risk compared with prosthetic implants. If it is impossible to create a brachial–cephalic AVF or after failure, either a brachial–basilic (BB) or a prosthetic forearm loop AVF may be considered. To determine the outcome of BB-AVFs, we retrospectively surveyed the results of this type of vascular access. Methods. All BB-AVF patient records over a 6 year period were subtracted from an academic hospital registry. Primary failure and primary, assisted primary and secondary patency rates were calculated with the Kaplan–Meier method. Sex, diabetes mellitus (DM), pre-operative duplex diameters, complications and interventions were recorded and correlated with the patency rates. Results. A total of 31 BB-AVFs were created in a one-stage surgical procedure. Of the patients, 36% were male and 19% had DM. Only one patient had a primary failure, leaving 30 (97%) of the BB-AVFs functional for dialysis treatment. Four patients died within 1 year after the operation, one of them from a catheter sepsis. Primary, assisted primary and secondary patency rates after 1 year were, 58, 83 and 90%, respectively. Patient characteristics and pre-operative duplex parameters did not influence patency rates. Conclusion. The BB-AVF is an excellent third choice option for vascular access.
