Experience of stenting of the extracranial part of the internal carotid artery in patients with acute ischemic stroke

Abstract

Aim. To present the experience of stenting of the extracranial internal carotid artery (ICA) in case of tandem steno-occlusive carotid lesion in the most acute phase of ischemic stroke.Materials and methods. From December 2018 to December 2021, 29 patients with acute ischemic stroke, because of tandem steno-occlusive lesions of the ICA and intracranial arteries, underwent endovascular surgery to restore cerebral blood flow.Results. Successful restoration of cerebral blood flow (according to the mTICI 2b–3 scale) achieved in 22 (75.9 %) patients. Four (13.8 %) patients had stent thrombosis in the early postoperative period. The incidence of symptomatic hemorrhagic transformation observed in 2 (6.9 %) patients. The frequency of a favorable functional outcome (Rankine 0–2) on the 30th day was 20.7 %, mortality – 24.1 %.Conclusion. Stenting of the extracranial ICA in patients with acute ischemic stroke improves the efficiency of restoration of cerebral blood flow. The use of low doses of glycoprotein receptor blockers prevents stent thrombosis in the early period after implantation and does not increase the incidence of symptomatic hemorrhagic complications.
