[A Nonagenarian Case of Less Invasive Two-stage Operation for Endoleak Following Thoracic Endovascular Aortic Repair].

ABSTRACT

A 85-year old male with hoarseness due to distal aortic arch aneurysm underwent zone 1 thoracic endovascular aortic repair( TEVAR) with two-debranching at our hospital. Five years after the TEVAR (90 years old), computed tomography( CT) revealed typeⅠa endoleak due to migration of proximal end of the graft. Anatomically, additional TEVAR was impossible. To minimize the invasiveness, a two-stage surgery was planned. First, under deep hypothermic circulatory arrest, the ascending aorta was replaced with the brachiocephalic artery reconstruction and insertion of a stented vascular prosthesis distally through partial sternotomy to preserve the debranching bypass. Six days after the surgery, a transcatheter stent graft was placed from the stented vascular prosthesis to the native descending aorta. Postoperative course was uneventful, and CT scan showed no endoleak.
