[Surgical treatment of ruptured descending aortic aneurysm to the right extra thoracic space: a case report].

A fifty-nine year-old woman was emergently admitted to our hospital for the aneurysm in descending aorta. She complained of severe back pain and dysphagia, and showed extreme hypotension. Aortic angiography was performed immediately. It revealed the aneurysm of descending aorta (phi 7.2 cm) and abdominal aorta (phi 3.5 cm), and also showed obstruction of bilateral common iliac arteries. On chest X-ray, a diffuse shadow of the right-sided chest was found. Through chest drainage, fresh blood was let out from extrapleural space. On the next day, the drainage blood markedly increased. Subsequently, emergent operation was performed. The operation consists of resection of aortic aneurysm with grafting and aortofemoral bypass with a Y shaped graft. The patient survived the operation and was discharged without any disability.
