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
Pathophysiology of aneurysm
Risk of rupture of aneurysm
Indication for AAA repair
