[Simultaneous pulmonary resection and endovascular repair for patients with coexisting primary lung cancer and aneurysm].

The surgical strategy for coexisting lung cancer and aneurysm is controversial owing to the risk of aneurysm rupture during the perioperative period of pulmonary resection. We performed simultaneous pulmonary resection and endovascular repair in 2 patients with coexisting lung cancer and aneurysm. Case 1:A 74-year-old man presented at our hospital with cT2aN0M0 lung cancer and a 5.0 cm abdominal aortic aneurysm. Because computed tomography indicated the possibility of advanced lung cancer, we decided to perform simultaneous surgery for lung cancer and the aneurysm. Under general anesthesia, endovascular aneurysm repair was performed before right lower lobectomy with lymphadenectomy. The postoperative course was uneventful, and the patient was discharged on postoperative day 12. Case 2:A 72-year-old man presented at our hospital with cT2aN1M0 lung cancer, a 5.0 cm left internal iliac artery aneurysm, and right renal cell carcinoma( RCC). Because the lung cancer was advanced and the patients needed following surgical treatment for RCC, we decided to perform simultaneous surgery for lung cancer and the aneurysm. Under general anesthesia, endovascular aneurysm repair was performed before right upper lobectomy with lymphadenectomy. The postoperative course was uneventful, and the patient was discharged on postoperative day 11.
