Salvage of an Avascular Thumb by Arteriovenous Flow Reversal and a Microvascular “Kite” Flap: Case Report

Abstract

This case report describes the salvage of an avascular thumb by retrograde venous arterialization. The thumb survived with a 30 percent tissue loss at the radial aspect. Soft-tissue reconstruction and contour correction were achieved with a new microvascular free flap--the free "kite" flap--from the contralateral index finger. Aesthetic and functional results were excellent, and the patient returned to his original occupation. It can be concluded that retrograde arterialization can provide successful salvage in replantation and revascularization under favorable circumstances.
