Dissecting Aneurysms

Dissection, Blood Vessel

An aneurysm caused by a tear in the TUNICA INTIMA of a blood vessel leading to interstitial HEMORRHAGE, and splitting (dissecting) of the vessel wall, often involving the AORTA. Dissection between the tunica intima and TUNICA MEDIA causes luminal occlusion. Dissection at the media, or between the media and the outer ADVENTITIA causes aneurismal dilation.
