[A case report of left postero-lateral thoracotomy for simultaneous CABG and left lower lobectomy].

Surgical management of patients with concomitant resectable lung lesions and critical cardiac disease is controversial. We report a case of concomitant pulmonary and cardiac surgery via a left thoracotomy. A 67-year-old male was admitted to our hospital complaining of recurrent bloody sputum and an abnormal shadow on chest X-ray. Chest CT and MRI showed a tumor in the left lower lobe (S10), with invasion of the diaphragm. A diagnosis of squamous cell carcinoma was obtained by transbronchial lung biopsy. The patient had a history of angina pectoris, and stress testing was positive. Coronary angiography showed 90% stenosis at segment 5, suggesting a risk of perioperative or postoperative myocardial infarction. This necessitated simultaneous surgical treatment for lung cancer and ischemic heart disease. A lobectomy of the left lower lung was performed, followed by coronary artery bypass grafting (CABG), using the great saphenous vein. The postoperative course was uneventful except for the occurrence of cholecystitis. Lung cancer and ischemic heart disease can be safely treated simultaneously via a single incision, with and benefit for selected patients.
