Thrombectomy vs. medical management for large vessel occlusion strokes with minimal symptoms.

Publication date: Aug 01, 2023

Patients with acute ischemic stroke (AIS) presenting mild symptoms with a low National Institutes of Health Stroke Scale (NIHSS) score ≤8 and also found to have an intracranial large vessel occlusion (LVO) undergo endovascular thrombolysis (ET) or medical management alone. The current study aimed to evaluate the safety and effectiveness of medical management vs. ET therapy among patients with mild AIS symptoms (NIHSS score ≤8) accompanied by LVO. The present meta-analysis included articles involving mild AIS, LVO, thrombectomy/ET and medical management alone published in full-text form (from 1980 to 2022). Collected variables included: First author name, covered study period, publication year, the total number of patients and age, number of males, presence of diabetes mellitus, hypertension, atrial fibrillation, prior ischemic stroke, location, NIHSS of admission, modified Rankin scale, bleeding, morbidity and mortality. After the initial search and applying all exclusion and inclusion criteria, eight articles were left in the final article pool. The total number of patients who underwent ET was 569, compared with 1097 with medical management for LVO strokes with minimal symptoms. The findings of the present meta-analysis study point out that ET management may be associated with a high risk of bleeding and mortality in patients with LVO presenting with mild symptoms (NIHSS score ≤8).
