Abstract Objective: To discuss the correlations between the ESSEN stroke risk score(ESRS) and intracranial vascular stenosis, vascular branch density and the infarct size respectively by the retrospective analysis of intracranial vascular characteristics in the cerebral infarction patients. Methods: 104 cerebral infarction patients confirmed by head MRI examinations and 3D-TOF-MRA in our department from July 2016 to June 2017 were investigated retrospectively. General information of patients were registered, the ESRS score and the infarct size were measured, and the features including the number of intracranial vessels with stenosis and the vascular branch density were analyzed. Patients were divided into low risk group and high risk group according to the ESRS. The differences of vascular characteristics including the vascular stenosis rate, the vascular branch density and the infarct size between two groups were compared by Chi-square analysis. The correlations between the ESRS and the intracranial vascular stenosis, vascular branch density and the infarct size were analyzed by the Spearman rank correlation. Results: The low risk group showed lower rate of intracranial vascular stenosis and higher vascular branch density than the high risk group. The ESRS was moderately positively correlated with the intracranial vascular stenosis, moderately negatively correlated with the vascular branch density and weakly positively correlated with the infarct size. Conclusion: The ESRS shows high correlation with intracranial vascular lesions, and high risk patients have more possibility of intracranial vascular stenosis.
