摘　　要：目的观察缺血性脑血管病（ICVD）患者的眼动脉及其主要分支的数字减影血管造影（DSA）解剖特征。方法对32例ICVD患者行DSA全脑血管造影检查，分别行颈总动脉、颈内外动脉和椎基底动脉造影，对眼动脉起点、经行和主要分支的特征进行观察。结果32例ICVD患者经DSA检查，除1侧颈内动脉闭塞外，其余63侧颈动脉未发现中、重度狭窄。63侧眼动脉均起自于颈内动脉床突上段、眼段。其中，58侧眼动脉呈单支，起自于颈内动脉；5侧眼动脉呈双支，一支起自颈内动脉，另一支中有4侧起自脑膜中动脉（颈外动脉分支），1侧起自大脑前动脉（颈内动脉分支）。眼动脉的主要分支有视网膜中央动脉和睫状后动脉；泪腺动脉和眼肌动脉；筛前、后动脉，眶上动脉，鼻背动脉，滑车上动脉，眼睑动脉。各分支起点变异较大。结论DSA检查提示，ICVD患者眼动脉主要起自于颈内动脉并为单支，但也存在双支情况。眼动脉主要分支起点变异较大。Objective To observe the digital subtraction angiography （DSA） characteristics of ophthalmic artery and its main branches in ischemic cerebrovascular disease （ICVD）. Methods The internal carotid arteries, external carotid arteries and ophthalmic arteries of 32 ICVD patients were examined for DSA. The characteristics of ophthalmic artery origin, trail and main branches were observed. Results Among 64 carotid arteries of 32 patients, there was one carotid artery with internal occlusion, there was no severe stenosis in the other 63 carotid arteries. The 63 ophthalmic arteries originated all from supraclinoidal and ophthalmic segments of internal carotid arteries. 58 ophthalmic arteries were single branch from the internal carotid artery. 5 ophthalmic arteries had 2 branches, one come from the internal carotid artery, the other come from the middle meningeal artery （external carotid artery branch ） in 4 cases or from the anterior cerebral artery （carotid artery branch） in 1 case. The main branches of ophthalmic artery included central retinal artery, posterior ciliary artery, lacrimal gland artery, ocular muscular artery; anterior ethmoid artery, posterior ethmoid artery, supraorbital artery, dorsal nasal artery, supratrochlear artery and eyelid artery. The beginning point of each branches were variable. Conclusions Ophthalmic arteries of ICVD patients primary arise from the internal carotid artery. It most often appears as single branch and occasionally as double branches. The beginning points of major branches of ophthalmic artery are variable.
