ABSTRACT
Objective:To compare the clinical outcomes of endovascular therapy in acute stroke patients with anterior circulation tandem occlusions caused by atherosclerosis or dissection.Methods:A retrospective cohort study. A total of 98 patients with anterior circulation tandem lesions undergoing endovascular therapy in the Wuhan NO.1 Hospital (March 2016 to March 2022) were analyzed. Median age was 64(55,71) years old, and 82.7% (81/98 cases) were males. According to the lesion etiology, the patients were divided into atherosclerosis and dissection groups. The differences in clinical outcomes between the two groups were investigated, including favorable 90-day functional outcome (modified Rankin Scale score of 0-2), successful reperfusion (modified Thrombolysis in Cerebrovascular Infarction score of 2b-3), symptomatic intracranial hemorrhage, stroke-associated pneumonia, 90-day all-cause mortality, and average hospitalization days. Logistic regression analysis was used to adjust for potential confounders affecting functional outcomes in both groups, and to determine odds ratios and 95% confidence intervals.Results:Seventy-one patients were grouped into the atherosclerotic cause and 27 into the dissection cause cohorts. The rate of favorable 90-day functional outcome was 43.7% (31/71 cases) in the atherosclerosis group versus 55.6% (15/27 cases) in the dissection group (adjusted odds ratio=1.339; 95% confidence interval, 0.374-4.798; P=0.654). No significant differences were found in other clinical outcomes between the two groups (all P>0.05). Conclusion:The clinical prognosis of patients with tandem lesions caused by atherosclerotic stenosis or artery dissection was similar after endovascular therapy. Future studies are still needed to verify our results.
ABSTRACT
Objective To investigate the predictors of death after endovascular mechanical thrombectomy (EMT) in patients with acute vertebrobasilar occlusive stroke (VBOS).Methods Patients with acute VBOS treated with EMT in Wuhan No.1 Hospital were enrolled retrospectively.The demographic and clinical data were collected.According to whether the patients died at 90 d after procedure,they were divided into survival group and death group.The demographic and clinical data were compared between the two groups.Multivariate logistic regression analysis was used to determine the independent risk factors for death at 90 d after EMT.Results A total of 47 patients were enrolled.The median age was 62 years,34 were males (72.3％),the median baseline National Institutes of Health Stroke Scale (NIHSS) score was 16,42 patients (89.4％) had recanalization (modified Thrombolysis in Cerebral Infarction [mTICI] 2b/3 grade),and 12 (25.5％) died within 90 d after procedure.Univariate analysis showed that the baseline NIHSS score (26 [21-28]vs.12 [5-23];Z=-3.165,P=0.002),percentage of neutrophil (81.61％ ± 11.82％ vs.72.20％ ± 12.09％;t =-2.137,P =0.033),neutrophil/lymphocyte ratio (10.54 ±7.17 vs.4.98 ±3.57;t =-2.393,P=0.017),and incidence of sICH (25.0％ vs.2.9％;x2 =5.627,P=0.018) in the death group were significantly higher than those in the survival group,while the percentage of lymphocyte (12.00％ ± 9.04％ vs.20.67％ ±10.39％;t =-2.429,P=0.015) was significantly lower than that of the survival group.Multivariate logistic regression analysis showed that high baseline NIHSS score (odds ratio [OR] 1.243,95％ confidence interval [CI] 1.046-1.318;P =0.038),high neutrophil/lymphocyte ratio (OR 1.278,95％ CI 1.002-1.630;P =0.049) and symptomatic intracranial hemorrhage (OR 5.088,95％ CI 1.065-38.718;P =0.046) were the independent predictors for death.Conclusion High baseline NIHSS score,high neutrophil/lymphocyte ratio and symptomatic intracranial hemorrhage are the independent predictors for death within 90 d after EMT in patients with acute VBOS.
