Reconstruction of limb soft-tissue defects: using pedicle perforator flaps with preservation of major vessels, a report of 45 cases

Abstract

We report on 45 pedicle perforator flaps without harvesting major vessels in limb reconstruction. Of our patients, 25 had major vessel injury resulting from their initial injury. In the upper extremities, there were 13 posterior interosseous artery perforator flaps, four ulnar artery perforator flaps and three radial artery perforator flaps. In the lower extremities, there were 16 peroneal artery perforator flaps with an axis on the sural nerve, five peroneal artery perforator flaps with an axis on the superficial peroneal nerve and four posterior tibial artery perforator flaps with an axis on the saphenous nerve. There were 42 successes, one total flap loss, one epidermal necrolysis and one distal tip necrosis. Greater utilisation of pedicle perforator flaps probably will occur because they are technically simple to execute, violate only the involved extremity, do not sacrifice a major source vessel, bring similar local tissues into a defect, avoid prolonged immobilisation and do not require microsurgical expertise. The concept of the pedicle perforator flap can be applied to the same axis of a neurocutaneous flap, even in cases with injured cutaneous nerves. © 2008.
