A peripheral artery aneurysm is when this condition affects an artery other than the aorta (the main artery in the body). This condition most often appears in an artery in the legs or neck. Several types of peripheral artery aneurysms exist:

  • Renal artery aneurysm: An aneurysm in the artery delivering blood to the kidneys
  • Femoral artery aneurysm: An aneurysm in the arteries in your groin
  • Popliteal artery aneurysm: An aneurysm in the artery behind the knees
  • Carotid artery aneurysm: An aneurysm in the artery in the neck


The symptoms of this condition vary based on which artery is affected and include:

  • High blood pressure
  • Pain on one side of the abdomen
  • Sudden leg pain
  • Weak or numb legs
  • Painful or discolored toes
  • Fainting
  • Stomach pain
  • Throbbing lump in neck, arm, leg, groin
  • Sores that won’t heal on fingers, toes

Diagnosis: What tests are needed?

To accurately identify the location of an aneurysm, you may require one or more tests, which could include ultrasound testing, a CT scan, an MRI, or an angiogram.

At Advanced Surgical Technology, we offer several diagnostic tests in-office, including:

  • Ankle-brachial index (ABI)
  • Arterial ultrasound
  • Diagnostic angiogram

We provide a range of tests for a pre-surgical workup and always ensure you are comfortable and fully informed throughout testing, diagnosis treatment, and recovery.

Treatment for a peripheral artery aneurysm in Mt. Vernon and Centralia

Your treatment plan will be customized to match your specific condition. The approach will reflect the location and size of the problem, the condition of your blood vessels in the area, and your general state of health.

For smaller peripheral artery aneurysms, we may recommend closely monitoring the condition, along with lifestyle changes. For larger aneurysms, a grafting procedure is most often the best and least invasive approach.

What is a graft?

A grafting procedure involves rerouting the blood supply flowing through the bulging area of the artery. A graft, whether natural or synthetic, is placed to bypass the aneurysm. It is most commonly performed endoscopically, a less invasive approach than open surgery, which is rarely needed.

What causes a peripheral artery aneurysm?

The causes behind developing a peripheral artery aneurysm are not fully understood, but some factors are known to increase risk:

  • Obesity
  • Smoking

Peripheral artery aneurysm in leg

The most common place a peripheral artery aneurysm develops is in the popliteal artery, the artery on the back of the lower thigh, running to the knee. Other common locations where peripheral aneurysms occur include the femoral artery (groin), carotid artery (neck), and the arteries supplying blood to your arms. If you have been diagnosed with a peripheral artery aneurysm in one leg, it is more likely you will develop (or have already developed) one in the other leg.
