The following are the major diseases or complications that may be contributed to by abdominal aortic aneurysm (AAA) (abdominal aortic aneurysm):
Cardiovascular System (I00-I99)
- Aortic dissection (synonym: aneurysm dissecans aortae) – acute splitting (dissection) of the wall layers of the aorta (main artery), with a tear of the inner layer of the vessel wall (intima) and hemorrhage between the intima and the muscular layer of the vessel wall (outer media), in the sense of aneurysm dissecans (pathological widening of the artery); can lead to the following disorders in particular:
- Acute renal failure
- Apoplexy (stroke)
- Paraplegia
- Aortic valve insufficiency – defective closure of the aortic valve of the heart.
- Aneurysm rupture (rupture (tear) of aneurysm; free or covered) – risk depends on diameter and growth rate:
- 1-2% for a diameter <5 cm
- 20-40% for a diameter > 5 cm
The risk of rupture for small aneurysms (3.0-5.5 cm) is 0-1.61/100 person-years over all [S-3 guideline].
- Hypovolemic shock (within seconds of free aneurysm rupture).
