Abstract: Introduction: up to the present day, there were no published multicenter randomized researches, that could compare combined concept of thrombectomy, including different methods of stent-retrievers traction with elements of aspiration and thrombolysis. There is no data on the effect of embolic complications after extraction of thrombus from cerebral arteries on outcomes of treatment. Aim: was to increase the effectiveness of treatment of patients with ischemic stroke basing on a comparison of results of various methods of endovascular thrombectomy from cerebral vessels and intravenous thrombolysis, and on the base of assessment of effect of distal embolism on treatment outcomes in acute period of ischemic stroke. Materials and methods: we carried out statistical analysis of results of different methods of thrombectomy in 75 patients and intravenous thrombolysis in 75 patients in acute phase of ischemic stroke. Effect of embolic complications after thrombectomy on outcomes of treatment of ischemic stroke was determined. Results: groups of patients were comparable in age, neurological deficit, sex, localization and stroke subtype. The first group is burdened by the proportion of documented cerebral artery occlusion, diabetes mellitus and ischemic stroke in anamnesis. Differences in deaths and disability rates were not reliable. Thrombectomy demonstrated neurological deficit regression at all evaluation intervals, as well as the superiority of 2 times at achievement of functionally independent outcome in comparison with intravenous thrombolysis group. Conclusions: a concept to thrombectomy, that supposes different methods of use of stent-retrievers and aspiration demonstrates better functional outcomes in treatment of ischemic stroke in the acute phase compared with intravenous thrombolysis. Embolic complications of reperfusion treatment adversely affect ischemic stroke outcomes and should be considered as a factor requiring minimization. References 1.
