title: Bilateral persistent sciatic arteries complicated with chronic lower limb ischemia.
abstract: BACKGROUND
  Persistent sciatic artery (PSA) is a rare vascular anomaly associated with a higher rate of aneurysm formation or thromboembolic complications causing lower extremity ischemia.
  
  
  METHODS
  A 15-year-old female patient with bilateral PSA presented with lower extremity ischemia. Considering the age and symptoms of the patient, we did not perform any intervention, but continued surveillance with duplex ultrasonography in case of the high incidence of aneurysmal formation or thromboembolic event.
  
  
  CONCLUSIONS
  Epidemiology, development, anatomical structure, diagnosis and treatments of PSAs are discussed.
  
  
  CONCLUSIONS
  PSAs, are prone to early atheromatous degeneration and aneurysm formation. Treatment of a PSA mainly dependent on the symptoms is either by surgical procedures or by endovascular interventions.
