Floating aortic arch thrombus involving the supraaortic trunks: Successful treatment with supra-aortic debranching and antegrade endograft implantation

摘要

A floating thrombus within the aortic arch is a rare condition that is generally detected after cerebral, visceral, or peripheral embolization. Endovascular exclusion of such mobile thrombus has been described but exclusively involved the descending aorta, or debranching of the supra-aortic trunk was done by open surgical bypass procedure. We present a case with a floating thrombus that extended throughout the whole aortic arch and involved all of the supra-aortic trunks. The pathology was treated by debranching the supra-aortic trunks using a new nonsutured Viabahn-based (W. L. Gore & Associates, Flagstaff, Ariz) technique (Viabahn Open Revascularization TEChnique [VORTEC]) for revascularization of the left common carotid artery and performing an antegrade endograft implantation from the ascending aorta, distal to the origin of the feeding graft for debranching, to the descending aorta in one procedure.
