Bipedicled fasciocutaneous flaps in the lower extremity

Abstract

It is well known that a bipedicled skin flap permits survival of longer flaps due to the secondary recruitment of vascularity. Inclusion of the deep fascia with such a flap, obeying the principles of the single-pedicled fasciocutaneous flap, provides even greater security for the immediate transposition of yet larger or riskier flaps without the need for delay maneuvers. This variation is especially valuable for the management of difficult wounds encountered in the lower extremity when no other local options may be available. Thirteen local bipedicled fasciocutaneous flaps including both vertical and horizontal orientations, without isolation of any discrete fascial perforators, have been successfully used for soft tissue coverage in the distal leg and ankle with only three (23%) minor complications as untoward sequelae. Another major advantage of this bipedicled version of the fasciocutaneous flap was that the inclusion of a distal pedicle simultaneously may be designed to prevent bone or tendon exposure at the donor site that otherwise frequently is a concern with a unipedicled flap.
