Stanford type A aortic dissection with intimal intussusception.

A 51-year-old man presented with acute chest pain and loss of consciousness. Computed tomography showed no intimal flap in the ascending aorta and clear dissection involving the aortic root and arch, as well as the descending aorta. At surgery, the intimal tear was found to be circumferential and dissection extended to the proximal aortic arch with intussusception of the intimal layer. Emergency graft replacement of the ascending aorta was performed successfully and his postoperative course was uneventful.
