Efficiency of mechanical thrombectomy in acute ischemic stroke patients

Abstract

The aim of this single-center study is to assess the outcomes in patients with acute ischemic stroke underwent endovascular mechanical thrombectomy. The data and outcome of patients who were admitted due to acute ischemic stroke caused by a large vessel occlusion in the anterior or posterior circulation and treated with endovascular stent retriever mechanical thrombectomy between 2014 and 2018 were retrospectively evaluated. Recanalization success was assessed based on Thrombolysis in Cerebral Infarction (TICI) scores, and the TICI grades 2b and 3 were considered as ‘successful’. Functional outcomes of the patients were assessed by modified Rankin Scale (mRS) at the 3rd month follow up and a score of ≤2 points was considered as ‘good clinical outcome’. Successful recanalization was achieved in 34 patients (69%). At the 3rd month follow-up, 23 patients (46,9%) had mRS scores of ≤2 points. The overall mortality rate at the 90th day was %30 (n=15). After endovascular thrombectomy, symptomatic intracranial hemorrhage was seen in 9 patients, groin hematoma due to vascular access in 5 patients, which did not require additional treatment, and pseudoaneurysm in 3 patients. Stent retriever mechanical thrombectomy is an effective and safe procedure in patients admitted due to acute ischemic stroke caused by large vessel occlusion. [Med-Science 2020; 9(3.000): 700-3]
