title: Intimo-intimal intussusception and other unusual manifestations of aortic dissection.
abstract: Four cases with unusual aortic dissection found unexpectantly at the time of operation, and their aortographic and anatomic findings and surgical treatment are described. One of the patients had a type I aortic dissection with intimo-intimal intussusception and another had a type I dissection with one portion of the intimal wall unidentifiable up to the origin of the innominate artery. One patient had a type III dissecting aneurysm with retrograde dissection into the aortic arch and ascending aorta, and the fourth patient had a dissecting aneurysm involving the ascending aorta and the innominate, right common carotid, and right vertebral arteries with a re-entry at the aortic arch.
