摘要
目的 探索前循环闭塞性脑卒中急性期磁敏感血管征(susceptibility vessel sign, SVS)阳性的影响因素。材料与方法 回顾性分析2020年7月16日至2022年6月24日河南省人民医院161例大脑中动脉闭塞并进行MRI检查的急性脑卒中患者资料,都包含可读的磁敏感加权成像(susceptibility-weighted imaging, SWI)信息。根据是否存在SVS比较了患者的特征,进行了单变量统计分析,然后将单变量统计分析中有意义的变量纳入到多变量统计分析。结果 SVS阳性(SVS+)与患者年龄、卒中病因、合并房颤/房扑均有关(P<0.05)。多因素分析显示,合并房颤/房扑是SVS+的独立危险因素[比值比(odds ratio, OR)=4.296;95%CI:1.248-14.791;P=0.021]。在症状出现-MRI时间方面,SVS+组和SVS阴性(SVS-)组之间差异无统计学意义。结论 在考虑症状出现-MRI时间的情况下,仍支持SVS作为急性缺血性脑卒中病因诊断的临床标志物。
Objective:To investigate the influencing factors of susceptibility vessel sign(SVS)in acute anterior circulation occlusive stroke.Materials and Methods:We retrospectively analyzed the data of 161 patients with acute stroke who underwent middle cerebral artery occlusion and MRI examination from July 162020 to June 242022,and all contained readable susceptibility-weighted imaging(SWI)information.The characteristics of the patients were compared according to the presence or absence of SVS.Univariate statistical analysis was performed,and then meaningful variables from the univariate statistical analysis were included in the multivariate statistical analysis.Results:SVS+was significantly correlated with age,cardiogenic stroke subtype and the combination of atrial fibrillation/flutter(P<0.05).Multivariate analysis showed that combined atrial fibrillation/flutter was an independent risk factor for SVS+(OR=4.296;95%CI:1.248-14.791,P=0.021).The difference between SVS+and symptom onset-MRI time was not statistically significant.Conclusions:SVS is still supported as a clinical marker for the diagnosis of the cause of acute ischemic stroke,even when symptom onset-MRI time is considered.
