- ANEURYSM: risk of rupture or embolism.
- DISSECTION: disruption of blood flow, potential rupture.
- ## RUPTURE: massive hemorrhage.
Common outcome of Aortic Aneurysm/Dissection/Rupture?
- ANEURYSM: gradual enlargement/ potential rupture.
- DISSECTION: Organ ischemia, extension of Dissection.
- RUPTURE: rapid death or severe morbidity.
Urgency of Aortic Aneurysm/Dissection/Rupture?
- ANEURYSM: needs monitoring but no intervention, unless symptomatic or large.
- DISSECTION: Often emergent.
- RUPTURE: Immediate emergency.
Aortic Aneurysm risk factors?
-Atherosclerosis
-hypertension
-trauma
-marfan syndrome
-hypotension
-smoking
-Family Hx
-Syphillis and other infections

- VASCULAR EMERGENCY - can result in loss of life or limb if not treated correctly.
