A Randomized Clinical Trial of Low-dose Warfarin Therapy for Improving the Longevity of Permanent Arteriovenous Catheters.

Background: The patency of a permanent arteriovenous catheter plays a significant role in the functioning of the catheter among patients dependent on the hemodialysis. Thrombosis formation is one of the most critical reasons for the short-term efficacy of the embedded catheters. The present study aimed to evaluate the efficacy and safety of warfarin for hemodialysis catheter failure prevention.
