Successful surgical treatment of impending rupture of thoracoabdominal aortic aneurysm in an elderly patient with severe pulmonary emphysema

Abstract

In a case of successful surgery for impending thoracoabdominal aortic aneurysmic rupture, an 83-year-old man with severe pulmonary emphysema was transferred to our hospital diagnosed with impending aneurysmic rupture. The aneurysm had been pointed out 2.5 years ago but surgical repair was not undertaken due to the patient's severe pulmonary emphysema. After admission, computed tomography showed an enlarging saccular thoracoabdominal aortic aneurysm. Emergency surgery was conducted because of severe pain below the left costal margin. We resected the wall of the saccular aortic aneurysm and reconstructed the aorta with an on-lay patch under femoro-femoral bypass and selective visceral organ perfusion. Tracheostomy provided respiratory care on the day following surgery. The patient was weaned from respiratory support 6 days after surgery. Postoperative aortography showed that the reconstructed thoracoabdominal aorta functioned satisfactorily. The patient remains in good health 18 months after surgery.
