Early Intraluminal Frozen Elephant Trunk Stent Graft Thrombosis After Aortic Arch Surgery.

Early postoperative intraluminal thrombosis is a frequent complication post FET surgery. Smaller stent graft sizes, larger or partially covered aneurysms, and major bleeding are associated with early thrombosis. Slight FET oversizing, prompt thoracic endovascular aortic repair completion, and early reintervention for major bleeding may prevent early thrombosis.
