Is a descending aortic aneurysm more dangerous than an ascending aortic aneurysm?

Is a descending aortic aneurysm more dangerous than an ascending aortic aneurysm?

Depends: Aneurysms are dangerous because many people don't know they have them until they rupture. Screening is important for people over 65 with family history of aneurysm, smoking or htn.

The problem is that when arteries (including the aorta) get too large, their walls become weak and prone to tear (dissection) or rupture. If this happens in the aorta it can be a catastrophe. Management of aortic aneurysms depends on where it is, how big, whether it's growing, ...Read more

How does an ascending aortic aneurysn differ from a descending aortic aneurysm?

How does an ascending aortic aneurysn differ from a descending aortic aneurysm?

Couple of things: Ascending aortic aneurysms occur anywhere from just after the heart to just after the takeoff of the blood brain vessels.

Generally speaking, ascending aneurysms are usually operated on, and descending are usually medically managed. Complicated topic. ...Read more

What is a dissecting aortic aneurysm?

Serious condition: An aortic dissection is when a tear develops in the inner layer of the aorta [which is a large blood vessel that branches from the heart] and blood enters between the inner and middle layers, causing them to separate. If the wall ruptures, then it is often fatal. If detected and treated early on, your chances of survival improves. With appropriate treatment your risk of death is 10%. ...Read more

Weak wall: The aorta is a living pipe. It has 3 layers, the inner layer or intima, the middle layer or media were some muscle like cells dwell and the adventitia rich in collagen fibers. The process of arteriosclerosis may result in slow death of the media which then gets replaced by collagen scar.
