颈动脉系统影像学检查在眼缺血综合征中的临床应用

Clinical application of carotid artery system imaging examination in ocular ischemic syndrome

目前超过90%的眼缺血综合征(ocular ischemic syndrome,OIS)由同侧颈动脉狭窄或闭塞引起,颅外段动脉狭窄的发生常代表着更严重的头颅动脉粥样硬化,导致远期缺血性脑卒中的发生。因此合理应用各种影像学方法检查OIS患者颈动脉系统尤为重要,可帮助眼科医师发现眼缺血症结所在,并以此为线索发现个体眼、颅乃至全身血管问题,实施积极对症处理并早期预防心脑血管危险事件的发生。

More than 90% of the ocular ischemic syndrome（OIS） are caused by ipsilateral carotid artery stenosis or occlusion. The occurrence of extracranial artery stenosis often represents more severe intracranial atherosclerosis, resulting in the occurrence of ischemic stroke. The examination of carotid artery system is important to help doctors find the origin of OIS, then to discover individual eyes, cranial and systemic vascular problems, and carry out active symptomatic treatment and early prevention of the cardiovascular risk events.
