Hybrid repair of an aortic arch aneurysm using double parallel grafts perfused by retrograde flow in endovascular repair combined with left subclavian artery surgical bypass

Abstract

Despite its invasive nature, open surgical repair is still the first choice to treat aortic arch aneurysms. With the advancement of endovascular technology, thoracic endovascular aortic repair (TEVAR) has gained popularity in treating aortic aneurysms; however, blood flow preservation of the supra-arch branches remains a complicated challenge. This case report describes a hybrid procedure that successfully treated a patient with aortic arch aneurysm by combining the parallel grafts perfused by retrograde flow in the TEVAR procedure and a carotid-subclavian artery bypass.
