ABSTRACT
Objective:To investigate the effectiveness and safety of endovascular therapy for acute progressive stroke caused by large vessel occlusion (LVO).Methods:Patients with progressive stroke caused by LVO admitted to the Department of Neurology, Yueyang Central Hospital from January 2019 to February 2022 were retrospective included. Patients with an Alberta Stroke Program Early CT Score (ASPECTS) or posterior circulation ASPECTS (pc-ASPECTS) ≥6 after progression were selected for endovascular therapy, including mechanical thromboectomy, thrombus aspiration, balloon angioplasty, stenting, or a combination of the above methods. Patients in the time window (anterior circulation within 12 h and posterior circulation within 24 h) and outside the time window (anterior circulation >12 h, posterior circulation >24 h) as well as those in the anterior and posterior circulation were compared.Results:A total of 20 patients with progressive stroke caused by LVO received endovascular treatment were included. There were 17 males and 3 females, aged 59.45±12.06 years. Three patients (15%) developed asymptomatic intracranial hemorrhage, and 12 (60%) had a good outcome 3 months after procedure. There were no statistically significant differences in the rate of successful vascular recanalization, incidence of intracranial hemorrhage, and the rate of poor outcomes between patients within and outside the time window and between the patients with anterior and posterior circulation.Conclusion:Endovascular therapy may be safe and effective for patients with progressive stroke caused by LVO with ASPECTS or pc-ASPECTS scores ≥6.
