彩色多普勒超声对视网膜血管阻塞性疾病与颈动脉粥样硬化斑块关系的作用

Relationship between retinal vascular occlusion and carotid artery atherosclerotic plaque by color Doppler ultrasonography

目的探讨彩色多普勒超声分析视网膜血管阻塞性疾病与颈动脉粥样硬化（CAA）斑块关系的作用。方法选取65例视网膜血管阻塞性疾病患者（病例组）和50例对照患者（对照组）行颈动脉彩色多普勒超声检查，比较两组患者CAA斑块检出率及颈动脉狭窄程度。结果病例组CAA斑块检出率为64.62％（42／65），较对照组的22.00％（11/50）显著升高，差异有统计学意义（P〈0.05），病例组轻度狭窄34例，中度狭窄6例，重度狭窄2例；对照组轻度狭窄8例，中度狭窄3例，重度狭窄0例，两组颈动脉狭窄程度比较差异有统计学意义（P〈0.05）。结论CAA斑块与视网膜血管阻塞性疾病的发生密切相关，彩色多普勒超声是监测CAA斑块最简捷的方法，对临床视网膜血管阻塞性疾病的防治有重要意义。

Objective To explore the relationship between retinal vascular occlusion and carotid artery atherosclerotie （CAA） plaque by color Doppler ultrasonography. Methods Carotid artery color Doppler uhrasonography was performed in 65 patients with retinal vascular occlusion （case group） and 50 normal controls （control group）. To acknowledge the role of the CAA plaque in the oeurrence of retinal vascular occlusion by the detection rate of CAA plaque and stenosis degree of carotid arteries. Results The detection rate of CAA plaque was 64.62%（42/65） in ease group, which was higher than that in control group [22.00%（11/50）], and there was significant difference （P 〈 0.05）. Mild stenosis had 34 eases, moderate stenosis had 6 eases, severe stenosis had 2 cases in ease group, and 8, 3, 0 ease respectively in control group. There was significant difference in stenosis degree of carotid arteries between two groups （P 〈 0.05 ）. Conclusions CAA plaque is closely related to the ocurrence of retinal vascular occlusion. Color Doppler ultrasonography is the simplest and most effective method to monitor CAA plaque which has clinical significance in prevention and treatment of retinal vascular occlusion.
