[Concomitant lobectomy for lung cancer under intraaortic balloon pumping and coronary bypass grafting].

A 71-year-old man was admitted because of an abnormal shadow on the chest X-ray film. Chest computed tomography (CT) revealed a tumor in the right upper lobe. The diagnosis of lung cancer was made by transbronchial lung biopsy. He had suffered an infarction of the inferior myocardial wall at the age of 55 years. Preoperative coronary angiography revealed total occlusion of segment 1, 75% stenosis of segments 5 and 6, and 90% stenosis of segment 13. Since these coronary lesions could cause perioperative and postoperative myocardial infarction, the patient was scheduled to undergo surgery of both the heart and lung in a one-stage operation. Under intraaortic balloon pumping (IABP), we performed a right upper lobectomy of the lung, and coronary artery bypass grafting with cardiopulmonary bypass through median sternotomy. During the lobectomy and first postoperative day, a stable circulation was achieved with IABP. The postoperative course was uneventful. At present, that is 33 months after the operation, the patient presents no sighs of recurrence of lung cancer and has not suffered any anginal attack during follow-up. Lung cancer and coronary artery disease can be treated simultaneously by this procedure.
