Aortic Dissection

An abdominal aortic aneurysm occurs when there is focal dilation of the abdominal aorta caused by weakening in the aortic wall. This results in an increased diameter of the aorta over time.

Thoracic aortic dissection occurs when the intima of the aorta becomes compromised and “tears” or “dissects” a new layer that fills with blood between the intima and the media.
