目的:探讨颈动脉粥样硬化斑块与短暂性脑缺血发作的关系。方法:短暂性脑缺血发作患者123例行颈动脉CT血管造影检查,观察其颈动脉粥样斑块的形成状况,并与正常对照组比较。结果:短暂性脑缺血发作组颈动脉粥样硬化斑块发生率、不稳定性斑块发生率及颈动脉狭窄率高于正常对照组(P<0.01);颈总动脉分叉处粥样斑块的发生率及血管狭窄率高于颈内动脉起始部、椎动脉处、颈总动脉处(P<0.01)。结论:颈动脉粥样硬化与短暂性脑缺血发作有密切关系。
Objective: To investigate the relationship between carotid atherosclerosis plaque and transient ischemic attack. Methods: 123 patients with transient ischemic attack underwent carotid artery CT angiography to observe the formation of carotid atherosclerotic plaque, and compared with the normal control group. Results: The incidence of carotid atherosclerosis plaque, unstable plaque and carotid stenosis rate in transient ischemic attack group were higher than those in normal control group (P <0.01). Atherosclerosis of common carotid artery The incidence of plaque and stenosis rate were higher than those at the beginning of carotid artery, vertebral artery and common carotid artery (P <0.01). Conclusion: Carotid atherosclerosis has a close relationship with transient ischemic attack.
