Femoral Aneurysm

Make an Appointment

A femoral aneurysm is bulging and weakness in the wall of the femoral artery, located in the thigh. Femoral aneurysms can burst, which may cause life-threatening, uncontrolled bleeding. The aneurysm may also cause a blood clot, potentially resulting in leg amputation.

Causes of Femoral Aneurysms

The exact cause of femoral aneurysms is not known, though atherosclerosis may play a key role. Trauma to the artery may also cause a femoral aneurysm.

Are You at Risk?

You may be at risk for a femoral aneurysm if you:

  • Have high cholesterol
  • Have high blood pressure
  • Smoke
  • Have a bacterial infection
  • Have had blood-vessel reconstruction in one or both legs

Many femoral aneurysms have no symptoms. The most common symptom is pain below the knee.

Femoral Aneurysms: Diagnosis & Treatment

We can diagnose you with tests that include:

  • Ultrasound
  • Computed tomography (CT) scan
  • Magnetic resonance imaging (MRI) scan
  • Angiography

Surgery is generally required to treat femoral aneurysms. Your surgeon will replace the artery with a graft or create a bypass around the area of the artery where the aneurysm is located.

It's important for you to carefully control high blood pressure with medication, if necessary.
