They may be infrarenal (most common) or suprarenal. They usually start below the renal arteries and end above the iliac bifurcation. They can be saccular or fusiform, often with atherosclerotic plaques and large mural thrombi. AAA are usually asymptomatic until they rupture, at which point they are rapidly deadly and have a terrible prognosis. The mortality is 80%, and only 50% ever reach the hospital alive. Anterior ruptures into the abdominal cavity have the highest mortality and rarely reach the hospital alive. Posterior ruptures into the retroperitoneum limits bleeding somewhat, having a lower mortality. | ||

Surgery may be endovascular or open. Endovascular aneurysm repair (EVAR) is preferred. Entry to the aorta is achieved through the femoral or iliac arteries. An expandable stent graft is place inside the lumen of the AAA. | Surgery may be endovascular or open. Endovascular aneurysm repair (EVAR) is preferred.
