Object.作者对眼动脉（OphA）的显微外科解剖进行了研究，特别注意其与脑膜中动脉（MMA）可能发生的危险性吻合。在7具成人尸头的14条血管标本上，对OphA及其与MMA的连接进行了显微外科解剖学研究。OphA分支的起源顺序与动脉是否沿着其眶内路线在视神经上方或下方交叉有关。视网膜中央动脉是从OphA穿过ON后的第一支分支，是从OphA穿过ON后的第二支分支。详细了解OphA的显微解剖结构并识别颈外动脉和OphA之间的动脉瘤对于避免血管内手术期间的灾难性并发症至关重要。
Object. The authors studied the microsurgical anatomy of the ophthalmic artery (OphA), paying particular attention to its possibly dangerous anastomoses with the middle meningeal artery (MMA).Methods. The microsurgical anatomy of the OphA and its anastomoses with the MMA were studied in 14 vessels from seven adult cadaveric heads. The origination order of the OphA branches varies in relation to whether the artery, along its intraorbital course, crosses above or below the optic nerve (ON). The central retinal artery is the first branch to course from the OphA when it crosses over the ON, and it is the second branch to course from the OphA when the artery crosses under the ON. Anastomoses between branches of the MMA and the OphA were present in the majority of the specimens examined.Conclusions. Detailed knowledge of the microanatomy of the OphA and recognition of anastomoses between the external carotid artery and the OphA are critically important in avoiding disastrous complications during endovascular procedures.
