Single-stage treatment of sternal wound complications in heart transplant recipients in whom pectoralis major myocutaneous advancement flaps were used.
Treatment of sternal wound complications is controversial, particularly in immunosuppressed heart transplant recipients. Regardless of the severity of infection, we combine immediate, aggressive débridement with bilateral pectoralis major myocutaneous advancement flaps in a single procedure. Compared with management with pectoralis major turnover flaps or distant pedicled muscle flaps, treatment of these sternal wounds with pectoralis major myocutaneous advancement flaps is simpler and quicker and provides better aesthetic results. Furthermore, because pectoralis major myocutaneous flaps are based on the thoracoacromial arteries, whether or not the internal mammary arteries have previously been harvested for coronary grafts is irrelevant. Twenty consecutive heart transplant recipients with sternal wound complications were treated with this technique. No intraoperative or perioperative deaths occurred. The morbidity rate was 30%, with seroma treated by needle aspiration in four patients (20%) being the most common complication. Only one patient had a postoperative wound infection. All patients had excellent functional and aesthetic results.
