目的探讨彩色多普勒超声检查对一过性黑矇患者颈动脉粥样硬化性狭窄形成的诊断价值。方法采用病例对照研究。选择眼科确诊的一过性黑矇患者和非一过性黑矇患者各60人作为研究对象,均行颈动脉彩色超声检查,比较两组间的颈动脉硬化程度。结果一过性黑矇组的颈动脉粥样硬化斑块总检出率显著高于对照组(P<0.01);一过性黑矇组的颈动脉中重度狭窄的发生率明显高于对照组(P<0.01)。结论彩色多普勒超声检查可以早期诊断一过性黑矇患者动脉粥样硬化性狭窄的形成。
Objective To investigate the diagnostic value of color Doppler ultrasonography in the diagnosis of carotid atherosclerosis in patients with transient amaurosis. Methods Case-control study. 60 ophthalmologically diagnosed patients with transient amaurosis and 60 patients with non-transient malaria were selected as study subjects. Carotid color ultrasound was performed to compare the degree of carotid atherosclerosis between the two groups. Results The total detection rate of carotid atherosclerotic plaques in the transient amaurosis group was significantly higher than that in the control group (P <0.01). The incidence of moderate-severe carotid stenosis in the transient amaurosis group was significantly higher than that in the control group (P <0.01). Conclusion Color Doppler ultrasound can diagnose the formation of atherosclerotic stenosis in patients with transient amaurosis.
