An unusual case of femoral arteriovenous fistula associated with acute limb ischemia following femoral vein catheterization for hemodialysis

Um caso incomum de fístula arteriovenosa femoral associada a isquemia aguda de membro após cateterização da veia femoral para hemodiálise

Abstract

Co-occurrence of acute limb ischemia (ALI) and arteriovenous fistula (AVF) as a manifestation of inadvertent arterial injury during percutaneous femoral vein dialysis catheter insertion is a rare and dangerous, but preventable complication. Iatrogenic femoral AVF commonly presents late, with leg swelling or high output cardiac failure. However, the co-occurrence of a femoral AVF with both progressive leg swelling, and acute thromboembolism has not been previously reported. We report the case of an iatrogenic femoral AVF with superficial femoral artery (SFA) thrombosis and distal embolism in a 53-year-old female who underwent percutaneous femoral access for temporary hemodialysis. Both the SFA and AVF were managed with open surgical repair.
