ABSTRACT
Objective:To explore the thickness and property of different plaques in neck computed tomography angiography(CTA) for the patients with carotid artery stenosis, and analyze the correlation between them and cerebral infarction or transient ischemic attack(TIA).Methods: 160 patients with carotid artery stenosis were divided into observation group (103cases) and control group (57cases) according to whether they had occurred cerebrovascular events. Through CTA for neck of patients to measure the thickness of different plaques and CT value in mild plaque in the image, and analyze the characteristic of these plaques and the correlation between them and cerebral infarction or TIA.Results: The thickness of mild plaque of observation group was significantly thicker than that of control group while the situation of thickness of hard plague was just statistically adverse. The results of analysis of regression indicated that there was a certain correlation between thickness of mild plaque and cerebral infarction or TIA event (r=0.926,P<0.05). Conclusion: There was a certain correlation between thickness of mild plaque in neck CTA and cerebral infarction or TIA event in patients with carotid artery stenosis. In clinical practice, the occurrence of cerebral infarction or TIA event can be forecasted through measure thickness of mild plaque of carotid artery, so as to achieve the aims of prevention and treatment for them.
