Summary
Arteriovenous fistula (AVF) is now the optimal method of obtaining vascular access for
dialysis. Measures such as systemic anticoagulation have been proposed as means of increasing
patency rates but enough evidence does not exist to support their use. The investigators
aimed to evaluate the efficacy of preoperative heparin injection on patency of AVF during the
first 24 hours after surgery and to determine whether such measure can be used to prevent
early thrombosis of the vascular access.
