[Simultaneous operation for lung tumor and cardiovascular disease].

Successful simultaneous operation for lung tumor and cardiovascular disease was performed in three cases. A 76-year-old man with stage I lung cancer and ischemic heart disease underwent a partial lobectomy following single coronary artery bypass grafting through a median sternotomy. A 62-year-old man with stage I suspected lung cancer and thoracic aortic aneurysm underwent a partial segmentectomy before aneurysmectomy and patch closure using vascular prosthesis through a left posterolateral thoracotomy. These two cases were performed under extracorporeal circulation. A 69-year-old man with bronchogenic carcinoma and abdominal aortic aneurysm underwent a left upper lobectomy with standard lympho node dissection following aneurysmectomy and grafting using vascular prosthesis. As a simultaneous procedure, limited operation for lung tumor, especially for stage I non-small cell lung cancer, is acceptable for cases in using extracorporeal circulation. On the other hand, except emergency ruptured cases of abdominal aortic aneurysm, standard radical operation for lung cancer as a simultaneous procedure is preferred for cases such as lung cancer accompanied with abdominal aortic aneurysm without extracorporeal circulation.
