Few patients with an embolism derived from apparently normal thoracic aorta with no other disease have been reported. We were presented with a case of a floating thrombus originating from the ligamentum arteriosum that caused multiple embolic episodes in the bilateral common iliac and superior mesenteric arteries. From our findings, we recommend a surgical approach for a floating thrombus in the aorta to prevent further embolism.
