We performed endovascular stent grafting of a perforated descending aorta, caused by empyema after surgery for lung cancer, in a 75-year-old man. After diagnosing hemorrhage from a perforation of the proximal descending aorta, caused by left empyema, the perforation was repaired with a saphenous vein patch and a pectoralis major muscle flap. However, re-hemorrhage from the same lesion occurred 2 months postoperatively. Temporary hemostasis was achieved with gauze packing and he was transferred to our hospital for endovascular stent grafting. The infection did not resolve after fenestration, so the descending aorta was cropped out to the fenestration lesion. Therefore, endovascular stent grafting was performed on the same day. Postoperatively the bleeding stopped completely without any signs of graft infection, and he was transferred to another hospital on postoperative day 9. No re-hemorrhage or graft infection of the aortic perforative lesion occurred in the early postoperative period. However, the patient died of massive bleeding from the aorta wall of the proximal stump of the stent graft, caused by recurrence of the infection 2 months after the 2nd operation. In this situation, endovascular scent grafting provides the only chance of saving the patient's life. If endovascular stent grafting is performed as a lifesaving procedure, meticulous operative technique is imperative.

We investigated the quality of life (QOL) after thoracic or thoraco-abdominal aneurysmectomy in patients who had undergone the procedure within the past 15 years. We compared preoperative to postoperative performance status (PS). Defining PS in the following manner: one increase in that PS grade indicated mild worsening while an increase is by 2 or more indicated severe worsening. Maintenance was indicated by no change of PS after surgery. The QOL maintenance rate was calculated based on the following formula.
QOL maintenance(%)=No. of no change case/No. of operated cases-No. of death×100
There were a total of 74 cases in whom follow-ups could be carried out after surgery. Among them, there were ascending and aortic arch aneurysms in 19 cases, descending aortic aneurysms in 20 cases, dissecting aneurysms in 27 cases and thoraco-abdominal aortic aneurysms in 8 cases. The QOL maintenance rate in the type B dissecting aneurysms was comparatively high (85.7%). There were cases of severe worsening of PS in the ascending and aortic arch aneurysms and type A dissecting aneurysms and the QOL maintenance rate was 50% in each other. We should obtain high operative results due to improve the QOL maintenance rate, and devise the operative procedure without functional disorders of the organs after surgery.

Morphology, location, timing of operation, and complications of multiple aortic aneurysms were investigated in 14 patients (10 men and 4 women with a mean age of 66 years). The locations of the aneurysms were as follows: aortic arch and thoracoabdominal aorta in 1, aortic arch and infrarenal abdominal aorta in 6, descending thoracic aorta and suprarenal abdominal aorta in 1, descending thoracic aorta and infrarenal abdominal aorta in 5, and thoracoabdominal aorta and infrarenal abdominal aorta in 1. Thoracic aortic aneurysms had a mean diameter of 63±13mm. The mean diameter of the abdominal aortic aneurysms was 54±13mm. In 1 patient, thoracoabdominal and infrarenal abdominal aortic aneurysms were operated on simultaneously. Eight patients, 5 with aneurysms of the aortic arch and infrarenal abdominal aorta, 2 with aneurysms of the descending aorta and infrarenal abdominal aorta, and 1 with aneurysms of the aortic arch and thoracoabdominal aorta, underwent two-staged operation. Aortic arch aneurysm was operated first in 3 patients, and abdominal aortic aneurysm in 5. Postoperative complications included spinal cord injury in 1 patient, bowel necrosis in 1, renal impairment in 2, respiratory impairment in 2, and hepatic impairment in 1. There was no perioperative death. Three late deaths occurred. Two staged operation is better for multiple aortic aneurysms. The first operation should be performed for the larger aneurysm.
