Skin Perforator Flaps: An Algorithm for Leg Reconstruction

ABSTRACT

The local fasciocutaneous flap has the advantage of low donor site morbidity when used for the coverage of lower limb defects. However, flap reliability remains a major problem with its use. Perforator flaps are indicated for several clinical problems. The versatility of the perforator flap makes it ideal for the reconstruction of extremities. Between September 2007 and November 2010, 34 skin perforator flaps were raised in 33 cases. Flaps which were executed as peroneal artery flaps were 13, 0.16 flaps were raised as posterior tibial artery perforator flaps, and 5 flaps as medial sural medial gastrocnemius muscle perforator skin flap. A segmental perforator was dissected and retained. Thirty-two flaps survived completely and none exhibited venous compromise. In one patient, flap was lost completely and the other showed partial tip necrosis. Complicated flaps were responded to conservative treatment. Skin perforator flap represents a technical advancement over conventional lower limb skin flaps because of its improved vascularity. It provides the surgeon with additional reconstructive options in reconstruction of difficult areas and injuries of leg. Clinical judgment is essential to assess the potential vascular territory of the flap.
