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.
