Aim: was to estimate results of endovascular treatment of subclavian arteries lesions.

Materials and methods: study analyzes results of endovascular treatment of patients with occlusive-stenotic lesions of subclavian arteries. For the period 2014-2018, 87 endovascular interventions were performed on subclavian arteries. Indication for surgery was occlusion of subclavian artery or stenosis of more than 70% with the development of steal-syndrome. Before surgery, all patients underwent duplex scanning of brachiocephalic vessels and CT angiography of branches of the aortic arch with cerebral phase. There was no difference in severity of symptoms and comorbidity between patients with stenosis or occlusions (р>0,05). In case of stenosis, direct stenting of subclavian artery was performed. For occlusions, mechanical recanalization was performed using hydrophilic wires, balloon angioplasty followed by stenting. In all cases, we used a balloon-expandable stent.

Results: technical success was achieved in 98,8% of interventions. There were no lethal outcomes, myocardial infarction, or stroke. In one patient, brachial artery thrombosis occurred in early postoperative period; thrombectomy from the brachial artery was performed with restoration of blood flow. Patency of subclavian artery after 1 and 3 years was 100% and 94%, respectively.

Conclusions: endovascular interventions for occlusive-stenotic lesions of subclavian arteries is an effective and safe method of treatment of vertebrobasilar insufficiency.
