    Abstract:
    Debranching thoracic endovascular aortic repair for aortic arch pathology is an important alternative to total arch replacement. However, the problem of intraoperative stroke due to atherosclerotic changes in the aorta remains. We apply our minimally invasive mini-cardiopulmonary bypass system to prevent intraoperative stroke during the endovascular procedure. Once debranching from the right axillary artery to the left common carotid and the left axillary artery is constructed; only the brachiocephalic artery is a pathway to the brain. After mini-cardiopulmonary bypass using the debranching graft is established, all cerebral perfusions are not only maintained, but retrograde blood flow from the brachiocephalic artery to the aortic arch is secured. All endovascular procedures can be performed under this situation. Our technique could be effective for preventing intraoperative stroke for endovascular repair with the debranching method for aortic arch pathology.
