How often should you have your popliteal aneurysm checked?

Annually: Once a year by ultrasound should be enough. You don't have to be concerned about treatment until it reaches a diameter of around 2cm. We don't worry about rupture. It is the formation of a blood clot and blockage of flow to the foot which is more likely to occur. These can be fixed surgically by replacing the short segment of artery or stenting.

Up to your surgeon: If you have popliteal artery aneurysm you are at risk for leg amputation. Doppler and cta will give needed info. May need surgery or covered stent soon depending on size of aneurysm, amount of clot in aneurysm and amount of associated peripheral artery disease. Otherwise your doctor will recommend follow up. You are at increased risk of abdominal aortic aneurysm so get an ultrasound of that area.
