目的初步探讨一过性黑矇患者颈动脉粥样硬化性狭窄的特点。方法应用彩色多普勒超声诊断仪对眼科确诊的一过性黑矇组和对照组颈动脉进行检测,观察有无狭窄、狭窄部位及狭窄程度。结果发生一过性黑矇的危险性随颈动脉粥样硬化性狭窄程度加重而增加,二者间存在线性关系,差异具有统计学意义(P<0.05)。结论颈动脉粥样硬化性狭窄、狭窄程度及狭窄部位与一过性黑矇有关联。
Objective To investigate the characteristics of carotid atherosclerosis in patients with transient amaurosis. Methods The colorimetric Doppler sonography was used to detect the carotid artery in the ophthalmologically diagnosed transient amaurosis group and control group. The presence of stenosis, stenosis and stenosis were observed. Results The risk of transient amaurosis increased with the severity of carotid atherosclerosis. There was a linear relationship between them (P <0.05). Conclusion Carotid artery atherosclerosis, stenosis and stenosis are associated with transient amaurosis.
