Arterial dissection

Changed by Andrew Murphy, 11 Jul 2016

Updates to Article Attributes

Body was changed:

Arterial dissection occurs when blood enters the media through a tear or ulcer in the intima and tracks along the media, forming a second blood-filled channel within the wall. The normal lumen lined by intima is called the true lumen and the blood-filled channel in the media is called the false lumen. The false lumen is at a higher pressure than the true lumen due to poor outflow.

Causes

In most cases the vessel wall is abnormal.
