First dorsal metacarpal arterialized venous (FDMAV) flap: intraoperative salvage of an ischemic FDMA flap by arteriovenous supercharging—a case report in thumb reconstruction

Abstract

Skin reconstruction because of deep wound on the dorsal thumb surface could be challenging. First dorsal metacarpal artery (FDMA) flap could provide excellent functional and cosmetic results. Although it is rare, intraoperative flap ischemia due to poor arterial inflow is possible. We describe an arteriovenous supercharging technique used to successfully revascularize a FDMA flap.Level of evidence: Level V, therapeutic study.
