title: Endovascular Treatment of the Subclavian Artery Steno-Occlusive Disease.
abstract: OBJECTIVE
  The aim of our study was to compare immediate and long-term results of endovascular interventions for the treatment of steno-occlusive disease of subclavian arteries (SAs) depending on the length of lesion.
  
  
  METHODS
  Between 2010 and 2013, we performed 245 endovascular procedures to treat patients with atherosclerotic steno-occlusive disease of SAs. All patients were examined and subdivided according to the received results into 2 groups: 125 patients with stenosis of SA were included in the first group and 120 patients with occlusion of SA were included in the second group. The patients were then followed up at 6, 12, 24, 36, and 48 months after endovascular interventions. Follow-up visits contained symptomatic evaluation, clinical assessment with physical examination, complete neurological evaluation, and serial color Doppler ultrasonography.
  
  
  RESULTS
  Transitory ischemic attacks in the vertebrobasilar system were intraoperatively developed by 1 patient from the first group (.8%) and 3 patients from the second group (2.5%). Reinterventions in the long-term period were carried out in 9 (7.2%) cases in the first group and 12 (10%) cases in the second group (P = .43). The cumulative primary stent patency at 4 years was 89.8% in the first group and 87% in the second group (P = .4).
  
  
  CONCLUSIONS
  In the case of SA occlusion on the first stage, it is expedient to carry out endovascular recanalization followed by stenting. Our study revealed an increased risk of stent thrombosis or in-stent restenosis in patients with stents >40 mm.
