A survival case of painless chronic type A aortic dissection with a history of stroke and anticoagulant use

We report the case of a patient with completely painless chronic aortic dissection, who presented to another hospital with a left hemiparesia 3 months ago and received anticoagulation therapy with a diagnosis of ischemic stroke. Most of her symptoms had resolved when she presented to our outpatient clinic except for numbness of her left hand and dysphasia. Physical examination found a diastolic murmur at the left sternal border and a bruit over the right carotid artery. Transthoracic echocardiography and carotid sonography demonstrated aortic dissection with extension into the internal right carotid artery and severe aortic regurgitation. Surgery was performed successfully and the patient was discharged. This case emphasizes that the diagnosis of a completely painless aortic dissection with only neurologic symptoms at presentation can be extremely difficult and should always be considered as a cause of ischemic stroke to avoid catastrophic antithrombolytic or anticoagulation therapy. © 2010 Wiley Periodicals, Inc.
