We studied 147 patients who underwent 171 interventions of transluminal balloon angioplasty with carotid artery stenting (CAS). Mean degree of stenosis measured by angiography before the intervention was 74±10%. Technical success (residual stenosis <30%) was achieved in 97% cases. Acute stroke during the intervention and in the early postoperative period was registered in 17 (11.6%) subjects: 11 (7.5%) patients had TIAs, 3 (2.05%) had “minor” stroke and 3 (2.05%) had “major” stroke. No events of myocardial infarction or death were observed. One hundred thirty-three patients (90%) were followed-up in the long-term perspective (21 [13; 38] months). Ipsilateral stroke was diagnosed in one patient (0.8%). No events of restenosis (≥50%) were observed in 155 cases of CAS. Asymptomatic stent occlusion was recorded 11 months after intervention in one patient (0.6%) who had subtotal stenosis of ipsilateral intracranial internal carotid artery. Thus, acute neurological deterioration develops mainly in the perioperative period, but the rate of stroke is low (4.1%). CAS is an effective method to prevent stroke in the long-term perspective in patients with extracranial carotid stenosis.
