| 目的 分析自发性头颈动脉夹层(spontaneous cervicoce-rebral artery dissection,SCAD)在高分辨力磁共振成像(high-resolution magnetic resonance imaging,HRMRI)中的影像学特征与急性缺血性卒中的相关性。 方法 对23例确诊为自发性头颈动脉夹层的患者进行HRMRI检查。排除心源性卒中及图像质量差者。由 2 名放射科医生对HRMRI 影像学特征进行双盲分析,评价内容包括内膜瓣、壁内血肿及夹层动脉瘤等。将每个患者划分为颈动脉系统及椎动脉系统4支血管节段进行观察分析。比较卒中组(发生急性缺血性卒中)和非卒中组(未发生急性缺血性卒中)SCAD患者HRMRI特征差异。 结果 最终21例患者纳入研究。84个血管节段中共诊断27个节段存在动脉夹层,其中累及颈内动脉系统11个节段、椎动脉系统16个节段。27个血管节段中11个节段存在供血区急性缺血性卒中。卒中组的管腔狭窄所占比例(54.5%)较非卒中组(19.2%)大,差异有统计学意义(P＜0.001),卒中组的壁内血肿(72.7%)所占比例较非卒中组(1.4%)大,差异有统计学意义(P＜0.001)。 结论 HRMRI存在管腔狭窄及壁内血肿的SCAD患者更易发生急性缺血性卒中。 |

| Objective To determine the relative contribution of imaging features by high-resolution magnetic resonance imaging (HRMRI) of patients with spontaneous cervicoce-rebral artery dissection(SCAD) to acute ischemic stroke. Methods A total of 23 patients with SCAD were underwent HRMRI．Patients with cardioembolism or poor image quality were excluded. HRMRI images were analyzed separately by two radiologists including intimal flip, intracranial hematoma , dissecting aneurysm and so on. Each patient was divided into four segments of carotid and vertebral arteries for observation and analysis. The imaging features between stroke group (patients with acute ischemic stroke) and non stroke group (patients without acute ischemic stroke) were compared. Results Totally 21 patients were recruited in this study. 27 of 84 vascular segments were diagnosed with SCAD, accompanying, 11 segments of the internal carotid artery system and 16 segments of the vertebral artery system. There were 11 of 27 vascular segments with ischemic stroke . The stenosis located at stroke group (54.5%) accounted for a higher proportion as compared with non stroke group (19.2%)(P＜0.001), and the intracranial hematoma located at stroke group (72.7%) accounted for a higher proportion as compared with non stroke group (1.4%)(P＜0.001). Conclusion Patients with sCAD complicated with stenosis and intracranial hematoma were more likely to have ischemic stroke. |
