Core Tip

Core Tip: Floating thrombus within the thoracic aorta is a rare but a life-threatening source of systemic emboli. The pathogenesis of floating aortic thrombi is not yet fully understood. Occult aortic dissection is a potential cause of floating aortic thrombus, which is most commonly detected at autopsy. Misdiagnosis may cause repeated recurrence of floating thrombus. We report a floating aortic thrombus caused by occult aortic dissection identified with the assistance of a three-dimensional printed model. Thoracic endovascular repair was the optimal treatment method in this patient, with promising results. Similar cases have not previously been reported.
