Aortic Aneurysm (Definition)

"Aneurysm" has scary implications for many people. It just means an enlargement of an artery. 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 aortic dissection differs from aortic aneurysm?

How does aortic dissection differs from aortic aneurysm?

Aneurysm/Dissection: An aneurysm is an area where the aorta has ballooned out compared to the aorta below and above. The more expanded the greater the risk of rupture. Dissection is when there is a disruption of the inner layer of the aorta and blood can flow between the layers. This often will cause blockages of aortic branch vessels resulting in stroke, heart attack, and bowel/kidney infarction, etc. ...Read more

What is the largest abdominal aortic aneurysm repaired?

Largest AAA repaired: You shouldn't think about it as, " is it too big to repair?" many anatomic details as well as a person's overall medical condition go into the decision as to if an aneurysm can be repaired.

What is a dissecting aortic aneurysm?

Amanda Xi Dr. Xi
14 doctors agreed:

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

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. In descending aneurysm, the site is any of the remaining aorta. This becomes complicated because one type can also turn into the other. Generally speaking, ascending aneurysms are usually operated on, and descending are usually medically managed. Complicated topic. ...Read more
