o:2964 Long-term follow-up of endovascular treatment for trans-atlantic inter-society consensus II type B iliac lesions in patients aged <50 years en 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]: 0.152e0.553; P ¼ 0.0001), lower preprocedural ankle-brachial index (HR: 2.438; 95% CI: 1.04e5.715; P ¼ 0.047), lesion length >5 cm (HR: 0.838; 95% CI: 0.746e0.943; P ¼ 0.003), and diabetes (HR: 2.005; 95% CI: 1.010e3.980; P ¼ 0.047) had significant influence on decreasing primary patency. CONCLUSION: 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. 91552100 126453769 1552101 0890-5096 1552099 10.1016/j.avsg.2011.09.008 2023-10-13T09:31:24.428Z 44 yes 46 Đorđe Radak 0000-0003-3199-5613 46 Srđan Babić 0000-0001-9659-9190 46 Dragan Sagić 0009-0002-2516-6480 46 Zelimir Antonić 0009-0002-2516-6480 46 Vladimir Kovačević 0000-0002-7165-6096 46 Predrag Stevanović 0000-0002-6321-7376 46 Slobodan Tanasković 0000-0003-4216-6693 46 Vuk Sotirović 46 Petar Otašević 0000-0002-0362-5765 application/pdf 441158 https://unilib.phaidrabg.rs/o:2964 no yes 18 Podatak o licenci prema https://v2.sherpa.ac.uk/id/publication/10584 70 92000001 71A11 Annals of Vascular Surgery 26 8 1057 1063 2012
