At What Size Should an Aortic Aneurysm Be Repaired?

If the aneurysm is more than 5.5 centimeters in size, or if it's rapidly getting larger, your doctor may recommend surgery to repair the aneurysm. In many cases, doctors will run a catheter through the patient's femoral artery in the groin to the site of the aneurysm in the aorta, then implant a stent graft.

What size does an aortic aneurysm burst?

The larger an aneurysm is, the greater the chances are that it will rupture. It is estimated that an abdominal aortic aneurysm that is over 5.5 cm in diameter will rupture within one year in about 3 to 6 out of 100 men.

What size is considered a large aneurysm?

Aneurysms are also classified by size: small, large, and giant. Small aneurysms are less than 11 millimeters in diameter (about the size of a large pencil eraser). Large aneurysms are 11 to 25 millimeters (about the width of a dime).
