Comparison of clinical efficacy and safety between intravenous thrombolysis and endovascular therapy in patients with acute large vessel occlusion stroke of the posterior circulation

Abstract

To investigate the efficacy and safety of intravenous thrombolytic (IVT) therapy and endovascular (EV) therapy in patients with acute posterior large vessel occlusion stroke (PLVOS). A total of fifty patients with acute PLVOS were randomly divided into the IVT group and EV group. The general baseline data, post-treatment vascular recanalization rate, National Institute of Health Stroke Scale (NIHSS) score before and after intervention, prognosis, and perioperative complications were compared between the two groups. There were no significant differences in the overall baseline data between the two groups (p > 0.05). The post-treatment recanalization rate was significantly higher in the EV group (88.00%) than in the IVT group (64.00%, p < 0.05). The NIHSS score at 24 h post-admission was significantly lower and prognosis was significantly better in the EV group than in the IVT group (both p < 0.05). The EV group had significantly lower overall complication rate (16.00%) than the IVT group (48.00%, p < 0.05). Compared with IVT therapy, EV therapy can effectively improve neurological damage, vascular recanalization rate and prognosis as well as reduce the incidence of perioperative complications in patients with acute PLVOS.
