Abstract

New-onset antegrade Stanford type B aortic dissection (TBAD) after endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) is rare. The extension of aortic dissection leads to various symptoms and affects the stent graft. Moreover, various symptoms may arise owing to a stent graft being present. We describe 2 cases of complicated acute TBAD occurring after EVAR, which were ultimately fatal. The case in which rupture occurred could not be treated and the patient died. In another case with bilateral lower extremity malperfusion caused by collapse and occlusion of the endograft, extra-anatomical bypass was performed. Although the collapsed endograft gradually re-expanded, the patient ultimately died because of multiorgan failure. We have reviewed the literature and analyzed the treatment of complicated TBAD after EVAR.
