Postoperative complications necessitating right lower lobectomy in a heart-lung transplant recipient with previous sternotomy.

Heart-lung transplantation for treatment of end-stage cardiopulmonary disease continues to be plagued by many problems. Three primary ones are the technical difficulties that can be encountered, particularly in those patients who have undergone previous cardiac operations, the additional restriction on donor availability imposed by the lack of satisfactory preservation techniques, and the need for lung size compatibility. Two of these difficulties and others surfaced postoperatively in a heart-lung transplant recipient who presented a series of unique operative and therapeutic challenges. A 42-year-old woman with chronic pulmonary hypertension and previous atrial septal defect repair underwent a heart-lung transplantation in August 1985. The operative procedure was expectedly complicated by bleeding from extensive mediastinal adhesions from the previous sternotomy and bronchial collateralization. Excessive chest tube drainage postoperatively necessitated reoperation to control bleeding from a right bronchial artery tributary. Phrenic nerve paresis, hepatomegaly, and marked abdominal distention caused persistent atelectasis and eventual right lower lobe collapse. Arteriovenous shunting and low oxygen saturation necessitated right lower lobectomy 15 days after transplantation, believed to be the first use of this procedure in a heart-lung graft recipient. Although oxygenation improved dramatically, continued ventilatory support led to tracheostomy. An intensive, psychologically oriented physical therapy program was initiated to access and retrain intercostal and accessory muscles. The tracheostomy cannula was removed after 43 days and gradual weaning from supplemental oxygen was accomplished. During this protracted recovery period, an episode of rejection was also encountered and successfully managed with steroid therapy. The patient continued to progress satisfactorily and was discharged 83 days after transplantation. She is well and active 20 months after discharge.
