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).
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.
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.
作者研究了眼动脉（OphA）的显微外科解剖结构，特别关注其与脑膜中动脉（MMA）可能存在的危险吻合情况。
在来自7个成年尸体头部的14条血管中研究了眼动脉及其与脑膜中动脉的吻合情况。眼动脉分支的起始顺序因动脉在眶内走行时是在视神经（ON）上方还是下方交叉而有所不同。当眼动脉在视神经上方交叉时，视网膜中央动脉是眼动脉发出的第一分支；当眼动脉在视神经下方交叉时，视网膜中央动脉是眼动脉发出的第二分支。在大多数检查的标本中，脑膜中动脉和眼动脉的分支之间存在吻合。
详细了解眼动脉的微观解剖结构以及认识到颈外动脉与眼动脉之间的吻合在避免血管内手术期间的灾难性并发症方面至关重要。
