Ruptured type B acute aortic dissection（AAD）is a life-threatening condition, in which surgical treatment most often yields unsatisfactory results. We report a case of a ruptured type B AAD in a 67-year-old man detected on computed tomography that required a partial aortic arch replacement with reconstruction of the left subclavian artery with adjunct deep hypothermic circulatory arrest（DHCA). Although the patient had a postoperative stroke, he recovered markedly with rehabilitation. DHCA and open proximal anastomosis are useful for the surgical treatment of type B AAD, however, an elaborate strategy to prevent an intraoperative cerebral embolism is especially important.
