What is a dissecting aneurysm?
Dissecting aneurysms are not true aneurysms but rather hematomas within the arterial media that occur almost exclusively in the aorta. An intimal tear allows access of blood to the media, and luminal blood pressure causes propagation of the thrombus through the arterial media over the course of hours to days (Fig.

Can an aneurysm turn into a dissection?
An aneurysm can occur anywhere in the aorta. Having an aortic aneurysm increases the risk of a tear in the aortic lining (aortic dissection), as shown in the image on the right.
Can aortic dissection happen slowly?
First, slowly progressive aortic dissection, particularly painless aortic dissection, is easily underestimated, resulting in a delayed diagnosis.
