One-stage operation for descending thoracic aortic aneurysm and left lung cancer: a case report

Abstract

We performed concomitant graft replacement for descending thoracic aortic aneurysm and pulmonary resection for squamous cell carcinoma of the left upper lobe in a 79-year-old man. The tumor reached the parietal pleura. No distance metastasis was found, and the tumor was diagnosed preoperatively as a stage IIB (N0, M0, T3) tumor. The descending thoracic aortic aneurysm was saccular, with greatest diameter being 55 mm, and extending from TH5 to TH8. A left upper lobectomy was performed, and after irrigation with a large volume of saline diluted with povidone iodine, graft replacement for the aortic aneurysm was performed under femoro-femoral partial bypass. To prevent postoperative graft infection, the greater omentum was dissected and placed over the resected pulmonary hilum and the graft. The patient's postoperative course was uneventful. There was no sign of infection, and the patient was discharged 1 month after surgery. Artificial graft wrapping with the greater omentum was useful for the prevention of the postoperative graft infection in this case of surgical treatment of lung cancer and descending thoracic aortic aneurysm.
