MECHANICAL THROMBECTOMY IN ACUTE ISCHEMIC STROKE: A SINGLE-CENTER EXPERIENCE
Aim. To assess the results of a single-center experience in the endovascular treatment of acute ischemic stroke and compare the results with existing studies. Methods. 12 patients with acute ischemic stroke who underwent TREVO stent-retriever mechanical thrombectomy at Federal State Budgetary Institution “Research Institute for Complex Issues of Cardiovascular Diseases” were included in the study. The following primary outcomes were measured: 90-day modified Rankin scale (mRS) score, first pass effect (FPE) and TICI 2b-2/3, the incidence of postoperative hemorrhages and mortality at 90 days. Results. The majority of patient were male (66.7%) aged 59.5 [57.5; 66.5] years. All patients suffered from hypertension. Of them, 8 patients (61.5%) had a positive history of coronary artery disease. Seven patients (53.8%) smoked and had heart rhythm disorders. The median baseline NIHSS score was 13. 75% of patients had baseline mRS≥4 scores. 25% of patients out of 33.3% with tandem middle cerebral artery-internal carotid artery occlusions underwent carotid artery stenting. Good clinical outcomes (mRS≤2 at 90 days) were achieved in 77.8% (7/9) of survived patients. The 90-day NIHSS score was 4 [1; 5]. The first pass effect and TICI 2b-3/3 were achieved in 50% and 91.7% of patients. The incidence of postintervention hemorrhages and mortality at 90 days were 33.3% and 25% respectively. Conclusion. Stent retriever mechanical thrombectomy reported promising clinical results in a small cohort of patients with acute ischemic stroke.
