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

Abstract

Complex clinical-ultrasound study was carried our in 29 patientsbefore and after stenting of 29 subclavian arteries (SA)and 2 brachiocephalic trunks (BCT). In 28 cases damage ofSA/BCT was presented as stenosis and in 3 cases as SA occlusion.Сlinical picture of vertebrobasilar insufficiency and/orupper limb ischemia took place in 97% of patients.Ultrasound diagnostics of aortic arch branches showed highinformativity of the method in revealing the degree of theSA/BCT damage. Technical success was achieved in 94% ofcases. 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 in18.5% of observations (5 patients). Re-stenosis was clinicalasymptomatic in 3 of 5 patients. Smoking was found to be theonly significant risk factor associated with re-stenosis.
