Conservation of Major Leg Arteries When Used as Recipient Supply for a Free Flap

Abstract

The potential hazards of using proximal segments of leg arteries for end-to-end anastomosis to vessels in free flaps are examined, and alternatives are proposed. The convservation of the major tibial arteries seems highly desirable, to minimize any subsequent development of ischemic complications. Turning a free flap upside down moves the anastomosis to the distal part of the extremity, thus conserving most of the muscular branches of the recipient artery. Cutting the recipient artery distally and bending it back in recurrent fashion also allows for easy end-to-end anastomosis, with many technical advantages.
