目的探讨颈动脉硬化与短暂性脑缺血发作(TIA)的相关性。方法用彩超对120例确诊为TIA患者的颈部动脉内径、内-中膜厚度(IMT)进行测量,并观察有无斑块形成,并与120例正常人对比观察。结果 TIA组颈部动脉内-中膜增厚与斑块形成发生率较对照组明显增高(P<0.005)。结论 TIA与颈动脉硬化存在着线性关系,早期检测颈动脉硬化,可提高TIA的诊治率,进一步减少急性脑梗死的发生率。
Objective To investigate the relationship between carotid atherosclerosis and transient ischemic attack (TIA). Methods The color Doppler ultrasound was used to measure the diameter of medial artery and medial intima - media (IMT) in 120 patients diagnosed as TIA. The plaque formation was observed and compared with 120 normal subjects. Results The incidence of neck intima-media thickness and plaque formation in TIA group was significantly higher than that in control group (P <0.005). Conclusion There is a linear relationship between TIA and carotid atherosclerosis. Early detection of carotid atherosclerosis can increase the diagnosis and treatment rate of TIA and further reduce the incidence of acute cerebral infarction.
