MATERIALS AND METHODS: From January 1999 to February 2010, 56 patients (25 men with a mean age of 58 ± 8 years) underwent endovascular treatment for CTO of the SA. Duplex scans and arteriograms confirmed occlusion in all cases. Indications for recanalization were subclavian steal syndrome in 33 patients (58.1%), arm claudication in 13 patients (23.2%), and coronary ischemia in 7 patients (12.5%) who had a history of previous coronary artery bypass grafting that included left internal thoracic artery graft. Three patients (5.4%) were treated before the scheduled coronary artery bypass surgery, which included left internal thoracic artery graft. After successful recanalization, all arteries were stented, and all of the patients were followed-up at 1, 3, 6, and 12 months after surgery and annually thereafter. RESULTS: Successful recanalization of the SA was achieved in 46 patients (82.1%), and the complication rate was 7.1%. During follow-up (mean 40 ± 26 months; range 2 to 125), the primary patency rates after 1 and 3 years were 97.9% and 82.7%, respectively. At the end of follow-up, 76% of the arteries showed no evidence of restenosis. Univariate analysis failed to identify any variable predictive of longterm patency of successfully recanalized SA. CONCLUSION: Percutaneous transluminal angioplasty with stenting of the complete total occlusion of the SA is a safe and effective procedure associated with low risks and good long-term results. https://unilib.phaidrabg.rs/o:2950 doi:10.1007/s00270-011-0144-8 cobiss:125938953 ISSN: 0174-1551 Key words: clinical practice, angioplasty/angiogram, subclavian artery, chronic total occlusion, recanalization, peripheral vascular, arteriosclerosis occlusion http://creativecommons.org/licenses/by/4.0/legalcode Podatak o licenci prema https://v2.sherpa.ac.uk/id/publication/16401?template=romeo Initial and long-term results of endovascular therapy for chronic total occlusion of the subclavian artery CardioVascular and Interventional Radiology(35) Babić, Srđan Sagić, Dragan Radak, Đorđe Antonić, Želimir Otašević, Petar Kovačević, Vladimir Tanasković, Slobodan Ružičić, Dušan Aleksić, Nikola Vučurević, Goran
