基于高分辨核磁血管成像技术的急性卒中患者颅内动脉狭窄特征分析

Feature Analysis of Intracranial Artery Stenosis in Patients with Acute Stroke Based on High-resolution Nuclear Magnetic Angiography

目的探究高分辨核磁血管成像技术下不同急性卒中患者颅内动脉狭窄部位的分布特征。方法收集80例急性卒中患者的年龄、性别、狭窄部位信息,对不同人群动脉狭窄部位分布进行描述,多组连续变量比较用方差分析,计量资料比较用χ~2检验,危险因素分析用单因素logistic回归。结果研究发现,80例患者的平均年龄为(61.70±12.41)岁,不同年龄段患者的狭窄部位分布存在差异(χ~2=22.75,P<0.0001),不同性别患者的狭窄部位也存在差异(χ~2=12.23,P=0.0169),在男性患者中年龄是影响动脉狭窄部位的因素,在各年龄段中性别均不是影响因素。结论不同年龄、不同性别急性卒中患者颅内动脉狭窄部位分布不同,研究结果以期提高卒中患者的诊治的精准性,为减少卒中疾病负担提供一定依据。

Objective To explore the distribution characteristics of extracranial and extracranial artery stenosis in patients with different acute stroke under high resolution magnetic resonance angiography.Methods The age,sex and stenosis site information of 80 patients with acute stroke were collected,and the distribution of arterial stenosis in different population was described.Multiple groups of continuous variables were compared by analysis of variance,measurement data were compared by chi-square test,and risk factors were analyzed by univariate logistic regression.Results the average age of 80 patients was (61.70±12.41) years old.There were differences in the distribution of stenosis sites among different age groups (χ~2=22.75,P<0.0001),and there were also differences between different genders (χ~2=12.23,P=0.0169).Age was the factor affecting the location of arterial stenosis in male patients,but not in all age groups.Conclusion the distribution of intracranial arterial stenosis is different in patients with acute stroke of different ages and genders.The results of this study are expected to improve the accuracy of diagnosis and treatment of stroke patients and provide a basis for reducing the burden of stroke.
