Comparison of the Efficacy and Safety Between Intravenous Thrombolysis, Direct Endovascular Therapy, and Bridging Therapy for Acute Basilar Artery Occlusion in Cerebral Infarction Patients

To compare the efficacy and safety of intravenous thrombolysis (IVT), direct endovascular therapy (EVT), and bridging therapy (BT=IVT+EVT) for acute basilar artery occlusion cerebral infarction.One hundred and fourteen patients with acute basilar artery occlusion cerebral infarctions admitted between January 2020 and August 2023 were selected. Differences in the reperfusion rate, prognosis, incidence of stroke-associated pneumonia, and mortality rate were compared among the three groups.There was no statistically significant difference in the percentage of patients who achieved successful reperfusion (86.8% vs. 84.2%) or complete reperfusion (72.1% vs. 68.4%) between the direct EVT and BT groups (both P>0.05). There were no statistically significant differences in the rates of symptomatic intracranial haemorrhage (3.7% vs. 10.3% vs. 10.5%, P=0.763). There were statistically significant differences in the rates of good prognosis (mRS score 0-2) (59.3% vs. 30.9% vs. 26.3%, P=0.021), stroke-related pneumonia (29.6% vs. 66.2% vs. 36.8%, P=0.002), and mortality (14.8% vs. 48.5% vs. 42.1%, P=0.010) among the three treatment groups. According to the binary logistic regression analysis, a good prognosis was independently associated with a baseline National Institutes of Health Stroke Scale (NIHSS) score <=10 (odds ratio [OR], 3.714; 95% confidence interval [CI], 1.207-11.430; P =0.022) and the incidence of stroke-associated pneumonia (OR, 0.640; 95% CI, 0.484-0.845; P=0.002).Although there were differences in prognosis, mortality, and incidence of complications among the three treatment groups, after adjusting for confounding factors, prognosis was independently correlated only with the baseline NIHSS score and stroke-associated pneumonia but not with treatment methods.
