中文摘要:
      头颈部CT动脉造影(CTA)指环征被认为是诊断颈动脉粥样硬化易损斑块的新特征,但迄今缺乏有效的病理学或临床确证。本研究依据临床头颈CTA检查结果设置指环征阳性及阴性病例组,回顾分析两组患者急性脑梗塞发生率及一般临床指标的差异,探讨影像学指环征与易损斑块导致缺血性脑梗塞临床后果间的关联。结果表明,指环征阳性患者更倾向于发生脑梗塞(χ2=8.104,P=0.004);性别、年龄、血压及空腹血糖水平可影响指环征的形成(P<0.05)。提示指环征和急性脑梗塞的发生存在关联,其可能成为影像学诊断易损斑块及预测脑梗塞发生的新指标。
英文摘要:
      Rim sign at cervical CT angiography (CTA) map has been considered as a new diagnosis imaging character for vulnerable plaque of cervical artery.However,the effective pathology or clinical validation was still lacking.In the present study,included patients were divided into two groups according to positive or negative rim sign,the incident of acute brain infarction and average clinical data were retrospectively analyzed.The result revealed the patients owing positive rim sign was prone to acute brain infarction(χ2=8.104,P=0.004) and sex,age,blood pressure,and fasting blood glucose level affected the formation of rim sign(P<0.05).It suggested that rim sign was relevant to the incident of acute brain infarction and possessed potential value in vulnerable plaque diagnosis and acute brain infarction prediction.
