doi:10.7517/issn.1674-0475.211209

Abstract

Abstract: This paper discussed the predictive value of CT middle cerebral artery regional collateral scoring system - Tan score for recurrent infarction in elderly patients with acute ischemic stroke (AIS). 140 elderly AIS patients were selected, including 33 patients with recurrent infarction (observation group) and 107 patients without recurrent infarction (control group), the differences of clinical data, laboratory indexes and Tan score between the two groups were observed. The age of the observation group was significantly higher than that of the control group (P<0.05). Compared with the control group, the proportion of fibrinogen (FIB) and Tan score ≤1 in the observation group were higher (P<0.05), while the blood flow velocity of middle cerebral artery in the observation group were lower (P<0.05). Tan score was positively correlated with middle cerebral artery blood flow velocity (r=0.485, P<0.05). Logistic regression showed age, middle cerebral artery blood flow velocity and Tan score were the influencing factors of recurrent infarction in elderly AIS patients (P<0.05). The area under ROC curve of recurrent infarction predicted by Tan score was 0.685, P<0.05, and the sensitivity and specificity were 76.00% and 67.50% respectively. CT middle cerebral artery regional collateral scoring system Tan score has certain application value in predicting recurrent infarction
