【摘要】：目的探讨高分辨率磁共振成像(HR-MRI)在评估椎动脉夹层(VAD)方面对血管腔、血管壁结构及成分的显示效果。方法回顾性纳入2012年1月至2016年4月连续就诊且完成数字减影血管造影、磁共振血管造影、磁共振成像(MRI)和HR-MRI的5例VAD患者作为研究对象,比较和分析HR-MRI对VAD的诊断价值。结果HR-MRI能确定以下内容:(1)椎动脉粥样硬化斑块由大量脂质核心组成;(2)VAD内存在大面积的"假腔"和完全塌陷的"真腔";(3)HR-MRI能有效区分先天性椎动脉发育不全和动脉粥样硬化斑块。此外,基于经典MRI的病因诊断,在HR-MRI扫描后,2例患者加入了降脂药物治疗,2例患者在短时间内使用双重抗血小板药物。结论将HR-MRI应用于VAD患者的诊断中,能更详细地阐明受影响血管壁的状况,有助于临床医师更好识别个体患者的发病机制并选择最佳治疗药物。
[Abstract]:Objective to evaluate the value of high resolution magnetic resonance imaging (HR-MRI) in the evaluation of vascular lumen, wall structure and composition of vertebral artery dissection (VAD). Methods from January 2012 to April 2016, 5 patients with VAD underwent digital subtraction angiography (DSA), magnetic resonance imaging (MRI) and magnetic resonance imaging (HR-MRI). To compare and analyze the diagnostic value of HR-MRI in VAD. Results HR-MRI can determine the following contents: (1) the atherosclerotic plaque of vertebral artery consists of a large number of lipid cores, (2) there is a large area of "false lumen" and "true cavity" of complete collapse in VAD. (3) HR-MRI can effectively distinguish congenital vertebral artery dysplasia from atherosclerotic plaques. In addition, based on the etiological diagnosis of classical MRI, after HR-MRI scanning, 2 patients were treated with lipid-lowering drugs and 2 patients were treated with dual antiplatelet drugs in a short time. Conclusion the application of HR-MRI in the diagnosis of VAD patients can clarify the condition of the affected vascular wall in more detail and help clinicians to better identify the pathogenesis of individual patients and select the best therapeutic drugs.
