Combined resection of the aorta under a temporary bypass for advanced lung cancer invading the aorta

Abstract

Combined resection of the aorta were performed under a temporary bypass in 2 patients with advanced lung cancer invading the aorta. Case 1 : A 64-year-old man had large-cell carcinoma of the left-upper lobe invading the descending aorta. Left-upper lobectomy and combined resection of the adventitia of the aorta were performed under a temporary bypass between the left subclavian artery and the descending aorta. Case 2 : A 48-year-old man had adenocarcinoma of the left-lower lobe invading the descending aorta. Left-lower lobectomy combined with tubular resection and reconstruction of the descending aorta were performed under a temporary bypass between the proximal and distal side of the tumor in the descending aorta. Combined resection of the aorta under a simple temporary bypass is a useful technique for controlling lung cancer invading the aorta without assisted circulation.
