【摘要】:目的探讨核磁共振液体衰减反转恢复(FLAIR)序列血管内高信号(FVH)在急性后循环多发性脑梗死中的临床意义。方法收集2013年1月~2015年10月在我科住院的后循环脑梗死患者62例,其中多发性脑梗死患者28例,单发脑梗死患者34例。均行头部MRI检查,包括磁共振弥散加权像(DWI)、T_1加权像和FLAIR序列。比较两组患者的一般资料、常见脑血管病危险因素、实验室检查及影像学资料。采用Logistic回归分析后循环多发性脑梗死相关的危险因素。进一步探讨FVH的产生机制。结果后循环多发性脑梗死组与单发脑梗死组在性别、年龄、高血压、糖尿病、胆固醇、甘油三酯、低密度脂蛋白、心律失常、吸烟等方面差异无统计学意义(P0.05)。与后循环单发脑梗死比较,多发性脑梗死组FVH更多见、严重程度更高(P0.001)。Logistic回归分析显示FVH为后循环多发性脑梗死的独立危险因素(OR值1)。结论 FLAIR序列血管内高信号可作为后循环多发性脑梗死的参考征象,预示后循环严重狭窄。
