Abstract

Complications after a median sternotomy incision, which is used currently in most open heart surgery, are serious, although it is infrequent. Reconstruction of the sternal defect resulting from dehiscence of median sternotomy is still big challenge to the most plastic surgeons. Since vascularized greater omentum was transposed to eliminate mediastinal wound problems, many vascularized regional muscle flaps became mainstay in reconstruction of median sternotomy wound. We treated 13 patients with median sternotomy dehiscence between October of 1993 and March of 1998. In two patients, the wound problems were so confined to superficial tissue that debrided and closed primarily. Eleven patients with deep wound infection were managed with vigorous debridement of all necrotic tissues and resultant defects were covered with regional muscle flaps: rectus myocutaneous flap(3) and bilateral pectoralis advancement flap(8). We used the pectoralis major advancement flaps without counter incision at humeral insertion site and the dissections were limited only medial to the anterior axillary line to preserve the axillary fold. In five patients with larger defects, we elevated muscle and cutaneous flaps separately to make these flaps more mobile. Large portion of two rectus abdominis flaps could not survive, whereas pectoralis advancement flaps had mo special wound problems. Only one patient developed fistula due to remained wire, regardless to flap surgery.
