一过性黑朦与颈动脉粥样硬化的关系 |
| |
【摘要】 目的 探讨一过性黑朦与颈动脉粥样硬化的相关性。方法 因一过性黑朦首诊于眼科的患者64例行彩色多普勒显像(color Doppler flow imaging, CDFI)检测颈动脉粥样斑块情况，同时检测眼动脉和视网膜中央动脉血流动力学变化。结果 一过性黑朦患者颈动脉粥样硬化斑块检出率为90.63%，同侧眼动脉和视网膜中央动脉血流速度比无症状侧降低，比较差异有统计学意义。结论 一过性黑朦与颈动脉硬化性狭窄有关，颈动脉粥样斑块导致同侧眼血流速度下降。

Relationship between Anaurosis Fugax and Carotid Atherosclerosis. XU Jie_hui, CAO Yong_bao, LIN Yi_fang, et al. Department of Ophthalmology, Zhejiang Hospital, Zhejiang 310013, China
［Abstract］ Objective To investigate the relationship between anaurosis fugax and carotid atherosclerosis. Methods Color Doppler Imaging was used to examine carotid atherosclerosis and to quantitate hemodynamic parameters of ophthalmic artery(OA)、central retinal artery(CRA)、central retinal vein（CRV）in 64 patients with anaurosis fugax. Results The incidence of carotid artery atherosclerotic was 90.63% in patients with anaurosis fugax. The blood velocity in OA、CRA and CRV in carotid artery atherosclerotic side was much more slower than that in non_ carotid artery atherosclerotic side in anaurosis fugax patients. Conclusions Anaurosis fugax was interrelated with the degrees of carotid artery stenosis. The blood velocity was decreased due to the carotid atherosclerosis in the ipsilateral&n[1] [2] [3] 下一页
