Iliac Aneurysms: Diagnosis & Treatment

We can diagnose you through tests that include:

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

You and your healthcare provider will choose a treatment method that suits your needs. Options include:

  • Close monitoring: You may undergo regular screenings to check the size and growth of the aneurysm to determine if treatment is necessary.
  • Lifestyle changes: Steps such as quitting smoking, controlling diabetes and eating a low-fat diet to reduce cholesterol may help keep the aneurysm from growing.
  • Medication: You may receive medicine to reduce your cholesterol or blood pressure.
  • Surgery: UVA uses minimally invasive endovascular techniques (only requiring a small incision in the groin) to repair iliac aneurysms. Your surgeon may use a stent-graft or perform open surgery to repair the aneurysm.
