Classification of Ao Dz
|
|
|
|
Fusiform circumferential
|
most common in aorta, true aneurysm
|
|
|
Fusiform sacular
|
more common in cerebral artery
|
|
|
False or pseudo-aneurysm
|
disruption in arterial wall, leads to clot, fibrous material accumulation = "aneurysm," not true dilation of vessel wall; common in femoral artery
|
|
|
Dissecting sacular
|
Blood flows from lumen into middle layer of artery and cause adventitia to dilate out that looks like aneurysm or vice versa; outside can collapse into lumen and inhibit flow
|
