Intrathoracic transposition of a pectoralis major and pectoralis minor muscle flap for empyema in patients previously subjected to posterolateral thoracotomy.
The latissimus dorsi muscle flap cannot be used to eliminate an empyema cavity in patients who have previously undergone posterolateral thoracotomy, because of the division of this muscle. Moreover, thoracoplasty alone cannot sufficiently eliminate an empyema cavity that includes the thoracic apex, where space remains between the clavicle and the first rib. Therefore, we constructed a flap from the pectoralis major (P.Ma) and pectoralis minor (P.Mi) muscles to eliminate empyema cavities in five patients who had undergone lobectomy (n = 3) or pneumonectomy (n = 2) via posterolateral thoracotomy from 3 months to 40 years previously. All five patients had bronchopleural fistulae, and because of the previous upper lobectomy or pneumonectomy, they had large empyema cavities including the thoracic apex. Open-drainage thoracotomy was performed due to severe infection, and intrathoracic transposition of the P.Ma and P.Mi muscle flap with simultaneous thoracoplasty was carried out 7-124 weeks (mean 38 weeks) later. The P.Ma and P.Mi muscle flap easily reached the apex space with sufficient obliteration of the empyema cavity. All of the patients remained free of empyema 12-85 months after thoracic closure. The P.Ma and P.Mi muscle flap is useful for eliminating empyema cavities including the thoracic apex in patients who have previously undergone a posterolateral thoracotomy.
