  • Title: [Versatility of rectus abdominis muscle or myocutaneous flap--report of seven cases].

    Abstract:
    The rectus abdominis muscle, due to its strategic location in the abdomen with its dual blood supply and wide arc of transposition, is ideally suited to repair defects over the chest, abdomen, groin and perineum. The muscle is generally based on the superior epigastric artery, deep inferior epigastric artery and their associated capillary communications. From September 1989 to September 1990, at Taichung Veterans General Hospital, seven cases were presented utilizing unilateral rectus abdominis muscle or myocutaneous flap for local or free tissue transfer. The recipient areas included abdomen, groin, perineum, lower leg and a penis reconstruction. Of all flaps that survived, one developed minor skin necrosis causing urethral orifice stricture and urethrocutaneous fistula that later required repair. All cases achieved the surgical goals. There was no donor site infection, nor abdominal wall herniation but persisted wound pain in 2 cases was noted during the follow-up period. All patients resumed daily activity without limitation about six weeks postoperatively. The large skin territory with abundant soft tissue offers versatile flap design. The dissection is simple, speedy and straight foreward. The deep inferior epigastric vessels are long and their calibers are suitable for vascular anastomosis. Usually, the donor sites are primary closed. We recommend this flap as one to be considered in reconstruction planning and as a donor material for free tissue transfer.
