Influencing Factors of Recanalization after Intravenous Thrombolysis with Urokinase in Acute Cerebral Infarction Patients

摘要

Background: Intravenous thrombolysis (IVT) with urokinase is the standard reperfusion therapy for acute cerebral infarction (ACI) in China. Only about 30% patients who use urokinase for IVT can recanalize. Therefore, this study aimed to analyze the influencing factors of recanalization after IVT using urokinase in ACI patients. Methods: A total of 391 consecutive patients with a diagnosis of ACI from January 2013 to October 2019 were enrolled and divided into 2 groups: patients without recanalization and patients with recanalization. Related data were collected and analyzed. Results: Univariate analysis showed that there were significant differences in gender, atrial fibrillation, erythrocyte mean corpuscular volume, platelet large cell ratio (P-LCR), glucose (GLU), and severity of ICAS between patients without recanalization and patients with recanalization ( p < 0.05). Multivariate logistic regression analysis indicated that P-LCR (odds ratio [OR] = 0.17, 95% confidence interval [CI] = 0.03–0.89, p = 0.04), GLU (OR = 0.28, 95% CI = 0.11–0.67, p = 0.004), and ICAS severity (OR = 0.48, 95% CI = 0.32–0.76, p = 0.001) were the influencing factors of recanalization. Conclusion: For patients with higher levels of P-LCR, GLU, or ICAS severity, the recanalization rate might decrease after ACI.
