A 55-year-old man was transferred to our cardiovascular center because of right hemothorax and hemorrhagic shock. Emergency CT scan revealed a thoracoabdominal aortic aneurysm (Crawford's type I-A) ruptured into the right thorax. The aneurysm was exposed by Stoney's spiral opening approach. A 24 mm Cooley Dacron graft was implanted in end-to-end fashion between the descending thoracic aorta and the abdominal aorta just above the celiac artery. The use of aortic artery cannula, femoral artery cannula and flexible polyvinyl tube provided safe and simple means as a temporary bypass during this graft replacement. Postoperative course was uneventful.
