目的:探讨CTA检测脑梗死伴颈动脉狭窄患者脑血流动力学改变价值。方法:选择我院收治颈动脉狭窄的脑梗死患者200例作为研究对象,同期另选择120例正常人作为对照组,给予两者行CTA、CTP检查,比较不同狭窄程度患者和对照组的脑血流动力学的变化情况。结果:轻度狭窄、中度狭窄、重度狭窄及闭塞患者的脑血流动力学相关指标的变化和对照组相比较差别显著(P<0.05)。结论:CTA联合CTP成像可以综合评估脑梗死伴颈动脉狭窄患者脑血流动力学的变化情况,能帮助临床制定有效的治疗方案。

Objective: To investigate the value of CTA in detecting cerebral hemodynamic changes in patients with cerebral infarction complicated with carotid stenosis. Methods: Our hospital of carotid artery stenosis in patients with cerebral infarction and 200 cases as the research object, at the same time the other 120 normal persons as control group, both CTA and CTP to check the changes of cerebral blood flow dynamics in different degree of stenosis in selected patients and controls. Results:Mild stenosis, moderate stenosis, severe stenosis and changes in control group and cerebral hemodynamics in patients with occlusion of relevant indicators compared to the difference was significant(P<0.05). Conclusion: CTA combined with CTP imaging can evaluate cerebral hemodynamic changes in patients with cerebral infarction and carotid stenosis, and can help to establish effective treatment plan.
