Most small or slow-growing abdominal aortic aneurysms do not rupture. However, large or fast-growing abdominal aortic aneurysms may. Depending on the size and rate at which the aneurysm is growing, treatment may vary from watchful waiting to emergency surgery. More recently there is new technology being implemented.
Aneurysms are usually defined as a localized dilation of an arterial segment greater that 50% its normal diameter. Most aortic aneurysms occur in the infrarenal segment (95%). The average size for an infrarenal aorta is 2 cm; therefore, AAAs are usually defined by diameters greater than 3 cm.
