[Concomitant off-pump coronary artery bypass and left lower lobectomy for lung cancer;report of a case]

A 58-year-old man had an abnormal shadow in the left lower lobe on his computed tomography, and also had stenosis of the coronary arteries. Preoperative coronary angiography revealed severe stenosis of right coronary artery (RCA), left anterior descending artery (LAD), and left circumflex branch(LCx). The diagnosis of lung cancer was made by transbronchial lung biopsy. Initially, we scheduled to undergo surgery of both the heart and lung in 2stage operation. However, before surgery, the infection of cavity was caused by tumor growing, so we performed the surgery in 1stage operation. Off-pump coronary artery bypass and left lower lobectomy with lymph node dissection was concomitantly performed. The postoperative course was uneventful. He was discharged after confirming the patent bypass grafting on the 13th postoperative day. Histopathological diagnosis was squamous cell carcinoma without lymph node metastasis. Lung cancer and ischemic heart disease can be surgically treated simultaneously, benefitting selected patients.
