Introduction. Intravenous thrombolysis (IT) is the primary method of reperfusion therapy for ischemic stroke. Over the past couple of years, there has been a global trend towards the predominant use of the bolus forms of thrombolytic drugs that is caused by necessity to increase the reperfusion therapy rate to achieve its best outcomes.Aim. To evaluate the efficacy and safety of the use of non-immunogenic staphylokinase for IT in ischemic stroke in real-world clinical practice of the regional vascular center.Materials and methods. The clinical outcomes of the cohort of 50 patients who underwent IT with non-immunogenic staphylokinase were analysed.Results. The age of the patients ranged from 46 to 94 years and averaged 71.8 ± 10.0 years; 22% of patients were over 80 years of age. The NIHSS score at admission varied from 3 to 23 scores and averaged 11 (8-14) scores. 36% of patients had large artery occlusions. 14% of patients received a step-wise reperfusion therapy. The median door-to-needle time was 23 (18-26) minutes. 52% of patients didn’t develop any infarction area during control neuroimaging. 62% of patients required no further rehabilitation. Hospital mortality was 12%. 18% of patients developed hemorrhagic conversion mainly in the form of hemorrhagic infarction. 1 patient had a symptomatic hemorrhagic conversion. Major bleeding and angioedema were not observed.Conclusion. The analysis of 50 consecutive cases of IT in ischemic stroke using non-immunogenic staphylokinase indicates the high efficiency and safety of this method of reperfusion therapy.
