Immediate and long-term outcome of stenting of proximal parts of aortic arch branches

Complex clinical-ultrasound study was carried our in 29 patients before and after stenting of 29 subclavian arteries (SA) and 2 brachiocephalic trunks (BCT). In 28 cases damage of SA/BCT was presented as stenosis and in 3 cases as SA occlusion. Сlinical picture of vertebrobasilar insufficiency and/or upper limb ischemia took place in 97% of patients. Ultrasound diagnostics of aortic arch branches showed high informativity of the method in revealing the degree of the SA/BCT damage. Technical success was achieved in 94% of cases. Twenty seven (93%) patients were examined in dynamics, with average term of observation of 16 months [12, 30]. On color-coded duplex scanning, re-stenosis was detected in 18.5% of observations (5 patients). Re-stenosis was clinical asymptomatic in 3 of 5 patients. Smoking was found to be the only significant risk factor associated with re-stenosis.
