[A successful surgical case report of impending rupture of the true thoraco-abdominal aortic aneurysm induced by thrombosed-type acute aortic dissection (Stanford type A)].

Impending rupture of the true aneurysm of the thoraco-abdominal aorta induced by acute aortic dissection (Stanford type A) is very rare, and decision making of the therapeutic plain is difficult. A 88-year-old woman manifested severe back pain with hypotension. Chest computed tomographic examination revealed a true aneurysm of the thoraco-abdominal aorta and acute thrombosed-type aortic dissection (Stanford type A) with cardiac tamponade. Under the diagnosis of impending rupture of the thoraco-abdominal aortic aneurysm induced by acute aortic dissection (Stanford type A), graft replacement of the thoraco-abdominal aortic aneurysm and pericardial drainage were successfully performed. Two months later, computed tomographic examination revealed disappearance of the thrombosed false lumen in the ascending aorta.
