Outcome of Simultaneous and Staged Microvascular Free Tissue Transfer Connected to Arteriovenous Loops in Areas Lacking Recipient Vessels

Abstract

Temporary arteriovenous loops provide adequate recipient vessels and flow to supply microvascular free flap tissue transfer in areas lacking recipient vessels and in which no other reconstructive options exists. No statistical differences in complications and overall outcome were found between immediate or secondary free tissue transfer. Meticulous monitoring of microvascular perfusion, however, is mandatory in both approaches and early intervention is necessary to ensure successful tissue transfer.
