Dissection (medical)

MRI of an aortic dissection1 Aorta descendens with dissection2 Aorta isthmus

In medical pathology, a dissection is a tear within the wall of a blood vessel, which allows blood to separate the wall layers. By separating a portion of the wall of the artery (a layer of the Tunica intima or tunica media), a dissection creates two lumens or passages within the vessel, the native or true lumen, and the "false lumen" created by the new space within the wall of the artery.
