Aortic Aneurysm Size Chart. However as more than 90 of AAAs are infrarenal a normal-sized suprarenal aorta does not exclude an AAA. Risk of rupture is proportional to the size of the aneurysm.
It is estimated that an abdominal aortic aneurysm that is over 55 cm in diameter will rupture within one year in about 3 to 6 out of 100 men. Diameter between 5cm and 59cm have risk between 1 in total 30 and 1 in total 7. Medium AAA 45cm to 54cm across.
Intervention should be considered when the diameter of a thoracic aortic aneurysm reaches 55 cms in men and 50 in women.
