[Idiopathic Ascending Aortic Thrombosis with Multiple Embolism:Report of a Case].

ABSTRACT

Ascending aorta thrombosis unaccompanied by an aneurysm or a primary hypercoagulable state is rare. We report a surgical case of ascending aorta thrombosis with multiple emboli. A 44-year-old woman visited the hospital for evaluation of dysarthria and was diagnosed with multiple cerebral infarcts. Contrast-enhanced computed tomography (CT) revealed a mass in the ascending aorta and the brachiocephalic artery. We performed emergency removal of the masses and endarterectomy with cardiopulmonary bypass under hypothermic circulatory arrest. Histopathological examination of the resected specimen showed thrombi. The patient had an uneventful recovery and was discharged 12 days postoperatively. No recurrent thrombus or hypercoagulable state was observed for 3 years postoperatively.
