Intimo-intimal intussusception and other unusual manifestations of aortic dissection.
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.
