What is an aortic aneurysm?

Weak wall

Aneurysm
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. The pressure inside the aorta and the wall weakness will result in dilatation of the aorta and it could burst.

Is aortic aneurysm inherited?

Depends

Aorta
An aortic aneurysm can be the result of inherited conditions like Marfan's syndrome. Conversley, aortic aneurysms may appear 'de novo' in those without a family history and only clinical risk factors such as atherosclerosis and hypertension. Since the relationship between genetics and environment is complex, if there is a family history one should always be extra vigilant and monitor.

Aneurysm
The aorta is a living organ. Has 3 layers. Intima,media,adventitia. The aortic wall is nourished by the vasa vasorum. Arteriosclerosis creates cholesterol plaque, the vasa vasorum occlude, the media slowly dies and becomes replaced by collagenous tissue,pressure and collagenase activity weaken wall and it dilates excessively, if not repaired claims 17,000 americans/yr.70%infrarenal

Dr. George T Tsai answered:

Aortic aneurysm same as dissection?

No

Open-uri20121023-16981-1yf5loh
Aneurysm is the dilation of your artery that can rupture if it gets too big overtime. A dissection is when the layers of your artery separate - generally associated with traumatic injuries (blunt or sharp), it is usually an acute event. Sometimes you can see dissection when the aneurysm starts to leak. Make friend with a vascular surgeon
