title: Long-term follow-up of endovascular treatment for trans-Atlantic inter-society consensus II type B Iliac lesions in patients aged <50 years.
abstract: BACKGROUND
  To study the initial and long-term results of endovascular treatment in patients aged <50 years with trans-Atlantic inter-society consensus-II type B unilateral iliac lesions and chronic limb ischemia.
  
  
  METHODS
  From January 2000 to February 2010, 60 consecutive endovascular interventions were performed on 23 women and 37 men aged ≤50 years. After successful treatment, all patients were followed up at 1, 3, 6, and 12 months after the procedure and every 6 months thereafter.
  
  
  RESULTS
  Successful percutaneous revascularization of the iliac artery was achieved in 56 patients (93.3%). The early vascular-related complication rate was 6.7%. The primary patency rates at 1, 3, and 5 years were 88%, 59%, and 49%, respectively. Cox univariate analysis revealed that an age range of 45 to 50 years (hazard ratio [HR]: 0.290; 95% confidence interval [CI]: 0.152-0.553; P = 0.0001), lower preprocedural ankle-brachial index (HR: 2.438; 95% CI: 1.04-5.715; P = 0.047), lesion length >5 cm (HR: 0.838; 95% CI: 0.746-0.943; P = 0.003), and diabetes (HR: 2.005; 95% CI: 1.010-3.980; P = 0.047) had significant influence on decreasing primary patency.
  
  
  CONCLUSIONS
  Endovascular treatment of TASC-II type B iliac lesions in patients aged <50 years is a safe procedure with low procedural risk. Primary patency rates at 1, 3, and 5 years were 88%, 59%, and 49%, respectively.
