摘　　要：目的观察颈内动脉闭塞患者同侧眼动脉侧支循环血流影像特征。方法回顾性分析20例颈内动脉闭塞患者的影像资料。其中，男性11例，女性9例。年龄30-65岁，平均年龄（45±3）岁。所有患者均行眼动脉、脑动脉数字减影血管造影以及颈内动脉、眼动脉经颅彩色多普勒超声检查；6例患者同时行磁共振血管成像检查。观察患者同侧眼动脉的血供和侧支循环情况。结果20例患者均为单侧颈内动脉闭塞，颈外动脉脑膜中动脉分支与眼动脉之间的侧支循环给同侧眼动脉供血18例，占90．0％；对侧颈内动脉经前交通动脉向同侧颈内动脉、眼动脉代偿供血16例，占80．0％；后交通动脉向同侧颈内动脉、眼动脉代偿供血12例，占60．0％。结论颈内动脉闭塞患者同侧眼动脉的血流主要来自同侧颈外动脉脑膜中动脉分支、对侧前交通动脉和后交通动脉等。Objective To observe the characteristics of collateral circulation blood flow of ipsilateral ophthalmic artery in patients with internal carotid artery occlusion. Methods The imaging data of 20 patients with internal carotid artery occlusion were analyzed retrospectively. There were 11 males and 9 females, aged from 30 to 65 years, with an average age of （45±3） years. All the patients underwent digital subtraction angiography and transcranial Doppler examination, and 6 patients underwent simultaneous magnetic resonance angiography. The blood supply and collateral circulation of the ipsilateral ophthalmic artery were observed. Results All the patients had unilateral internal carotid artery occlusion. The blood supply of the ipsilateral internal carotid artery and ophthalmic artery comes from the collateral circulation between the middle meningeal artery branches of the external carotid artery and the ophthalmic artery in 18 patients （90.0%）; it also comes from the anterior communicating artery of the contralateral internal carotid artery in 16 patients （80.0%）; and the posterior communicating artery of the contralateral internal carotid artery in 12 patients （60.0%）, respectively. Conclusion The blood flow of the ipsilateral ophthalmic artery mainly comes from the middle meningeal artery branch of the ipsilateral external carotid artery, also comes from the anterior and posterior communicating arteries of the contralateral internal carotid artery. 0
