Aortic Floating White Thrombus in an Ascending Aortic Graft After Aortoplasty.

We encountered a 75-year-old man who underwent total arch replacement for a thoracic aortic aneurysm, then ascending aortoplasty for hemolysis due to a kinked ascending aortic graft. He presented with exhaustion and anemia 3 years later. Computed tomography revealed a large floating thrombus in the ascending aortic graft attached to the dorsal suture line. The thrombus developed after the graft kink was released, and although the dorsal mural thrombus disappeared, a floating white thrombus remained. Clinicians should ensure that the ascending graft is in a natural position without bending or kinking to reduce the risk of postoperative thrombus formation.
