aortic dissection

a pathologic process, characterized by splitting of the media layer of the aorta, which leads to formation of a dissecting aneurysm. Classified according to location as follows: type I involves the ascending aorta, transverse arch, and distal aorta; type II is confined to the ascending aorta; type III extends distally in the descending aorta usually from a starting point just distal to the left subclaviar artery.

while we are talking about aortic dissection:
aneurysms causes aortic dissection but what causes aneurysms??

aneurysms in the ascending aorta is caused by hypertension while aneurysms in the abdominal aorta is caused by atherosclerosis.

Quote:
aneurysms in the abdominal aorta is caused by atherosclerosis

or inflammatory AAAs

There are two variants of AAAs

the mycotic AAA which is the atherosclerotic infected by lodgement of salmonella ( suppurative organism ) for ex. or
the Inflammaotry AAA which is a dense periaortic fibrosis with a chronic cellular inflammatory infiltrate

Genes also can play a role if ur talking about marphan syndrome as an etiological factor

Mechanism of Marphan in AAA :

Since it is a genetic CT ( connective tissue ) component defect , proteolysis of abnormal collagen by macrophage enzymes will also lyse all ECM component in the arterial wall predisposing it to an atherosclerotic plaque

iatrogenic factors also can have a strong link with both aneurysm and dissecting hematoma

------

AAAs = abdominal aortic aneurysms - legal abb.

but i was wondering

if atherosclerosis leads to hypertension can we say that an AAA can aggrevate an ascending aortic aneurysm ?
