title: Rupture of a previously thrombosed thoracoabdominal aneurysm.
abstract: Spontaneous thrombosis of abdominal aortic aneurysms is rare. A patient with a 12-cm thoracoabdominal aneurysm developed sudden thrombosis of his aneurysm. He was treated with axillobifemoral bypass. He went on to rupture 7 months later. While spontaneous thromboses of abdominal aortic aneurysms have been previously reported, we did not find any reports of a thrombosed thoracoabdominal aneurysm or a subsequent rupture of this type of aneurysm. The literature on thrombosis of aneurysms is reviewed as well as proposed etiologies for thrombosis and subsequent rupture. We believe that resectional therapy may be warranted even in high-risk patients.
