Abstract:
Objective:To investigate the independent predictors of the long-term clinical outcomes in patients with branch atheromatous disease (BAD) in lenticulostriate artery (LSA) territory.Methods:Patients with LSA-BAD admitted to the Department of Neurology, Zhongnan Hospital of Wuhan University from January 1, 2016 to June 1, 2019 were enrolled retrospectively. Their demography, vascular risk factor, and baseline clinical data were collected. The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the severity of stroke. The clinical outcomes were evaluated by the modified Rankin Scale at 6 months. 0-2 was defined as good outcome, and >2 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of clinical outcomes in patients with LSA-BAD. Results:A total of 81 patients with LSA-BAD were enrolled. Their age 59.20±11.75 years (range, 39-81 years), 53 were male (65.4%), and median baseline NIHSS score was 1.0 (interquartile range, 0-4.0). Forty-one patients (50.6%) received intravenous thrombolysis. At 6-month follow-up after the onset, 63 patients (77.8%) had a good outcome, and 18 (22.2%) had a poor outcome. The baseline NIHSS score of the poor outcome group was significantly higher than that of the good outcome group (6.5 [0-9.0] vs. 1.0 [0-3.0]; Z=2.395, P=0.017), while the proportion of mild stroke (61.6% vs. 98.4%; χ2=17.595, P<0.001) and patients receiving intravenous thrombolysis (38.9% vs. 54.0%; χ2=4.450, P=0.035) were significantly lower than those of the good outcome group. Multivariate logistic regression analysis showed that after adjusting for other confounding factors, venous thrombolysis was independently correlated with the good outcome (odds ratio 0.099, 95% confidence interval 0.011-0.924; P=0.042), while the high baseline NIHSS score was independently associated with the poor outcome (odds ratio 1.736, 95% confidence interval 1.262-2.388; P=0.001). Conclusion:Intravenous thrombolysis is helpful to improve the outcomes of patients with LSA-BAD, and a higher baseline NIHSS score is an independent predictor of the poor outcome.
