Soft-tissue reconstruction in thoracic surgery.

Abstract

Reconstructive techniques using omental and myocutaneous flaps are widely used in the treatment of infected sternotomy wounds. To illustrate their wider role in thoracic reconstruction, we have retrospectively reviewed our experience over the last 5 years. We used complex omental and myocutaneous flaps in 30 patients: 19 men and 11 women with a mean age of 53 +/- 4 years (range, 43 to 75 years). In 18 patients, these techniques were used to provide soft-tissue cover after chest wall resection, and in 12 cases complex myocutaneous flaps were used to obliterate chronic intrathoracic cavities. Rectus muscle was used in 11 of 24 muscle flaps, and omentum was used in 12 cases. There were 23 rotational flaps and seven free myocutaneous flaps with microvascular anastomosis. There were no operative deaths, and there were three complications. In 2 patients with infected lesions, loss of the free flap required subsequent revision. In 1 patient, infection developed underneath a prosthesis, which was treated with drainage and rib resection. In all other cases, the primary aim of the operation was achieved without complications. The vascularity of the omentum should encourage its wider use, especially when infection exists preoperatively. Excellent results can be achieved when using the rectus muscle as a complex myocutaneous flap. The use of free flaps should be reserved for difficult cases and used only in the absence of infection.
