Perigraft Hematoma Following Late Transgraft Hemorrhage More Than 10 Years after Thoracic Aortic Replacement for Takayasu’s Arteritis

Abstract

Here, we present a rare case of perigraft hematoma secondary to late transgraft hemorrhage after thoracic aortic replacement. A woman with Takayasu’s arteritis underwent total arch replacement with elephant trunk primary and descending aortic replacement secondary to a knitted Dacron graft for a thoracic aortic aneurysm. Computed tomography revealed sudden protrusion of the ascending aortic graft proximal to the first branch 11 years after the first operation, which gradually enlarged with extravasation. Re-total arch replacement was performed under moderate circulatory arrest and antegrade cerebral perfusion. Surgical findings confirmed a perigraft hematoma caused by transgraft hemorrhage without graft infection or rupture.
