Thrombus on the intraluminal felt strip. A possible cause of postoperative stroke.

We report a case of a 60-year-old woman who received an operation for acute aortic dissection and who had a postoperative complication of multiple cerebral infarction. Through aggressive investigation using transesophageal echocardiography, a mobile thrombus on the intraluminal felt strip used for the enforcement of the dissecting aortic wall was detected as the possible source of the cerebral thromboembolism. After anticoagulation therapy was started, the mobile thrombus growing on the intraluminal felt strip disappeared, and no new lesions of cerebral thromboembolism occurred.
