Rupture risk of AAA increases with increasing aortic diameter and this catastrophic event is associated with a mortality of 50 - 80%. The force of blood pumping can split the layers of the artery wall, allowing blood to leak in between them. Curci JA, Thompson RW. AAAs are classified by location as either suprarenal or infrarenal aneurysms.Men of advanced age are at increased risk for their formation; smoking and hypertension are also major risk factors.AAAs are frequently asymptomatic and therefore detected incidentally.
