MATERIAL AND METHODS: A bi-center prospective, non-randomized study was conducted on 100 patients (mean age 59.14 ± 8.53; 64 men) who underwent endovascular treatment of iliac occlusive disease between January 2013 and November 2017. We evaluated baseline data, procedure, and follow-up results for the entire group, and according to Trans-Atlantic Inter-Society Consensus (TASC II) classification. The majority of patients (60%) were treated for severe claudication; 56 (56%) patients had TASC B occlusions, 28 patients TASC C, and 16 patients TASC D. RESULTS: The mean length of the occluded segments was 61.41 ± 35.15 mm. Procedural complications developed in 6 patients (6%). Mean ankle-brachial pressure index increased from 0.40 ± 0.12 preoperatively to 0.82 ± 0.16 postoperatively. The mean follow-up was 33.18 ± 15.03 months. After 1 and 5 years, the primary patency rates were 98% and 75.1%, and the secondary patency rate was 97% respectively. Regarding occlusion complexity there were no statistical significant differences in primary patency rates (TASC B vs. C vs. D: p = 0.19). There were no statistically significant differences in primary patency rates between patients in different clinical stages, as well as between the type of stents, and location of the occlusion. CONCLUSION: In our study, endovascular treatment for iliac artery occlusions proved to be a safe and efficient approach with excellent primary and secondary patency rates regardless of the complexity of occlusions defined by TASC II classification. This study is aligned with the notion that in well selected patients, endovascular therapy can be the treatment of choice even in complex iliac lesions if performed by experienced endovascular interventionists in high volume centers. https://unilib.phaidrabg.rs/o:2798 doi:10.1371/journal.pone.0222893 ISSN: 1932-6203 http://creativecommons.org/licenses/by/4.0/legalcode application/pdf 879212 bytes Endovascular treatment of different types of iliac occlusions: results from an observational study eng
