摘要
目的 为颅底显微外科手术提供显微解剖学基础。方法 应用 2 0例成人头颅湿标本 ,在放大 5×2 5倍手术显微镜下 ,对眼动脉的起源、行程及分支进行显微解剖学研究。结果 90 %眼动脉起源于颈内动脉床突上段 ,其中大部分起自颈内动脉上壁的内三分之一。 5 %眼动脉起源于颈内动脉海绵窦段。另 5 %眼动脉起源于脑膜中动脉。眼动脉分为颅内、管内及眶内 3段 ,眶内段依据其与视神经关系又被分为 3段。眼动脉的主要分支为视网膜中动脉、睫状后动脉、泪腺动脉及筛前、后动脉。结论 熟悉眼动脉的起源、行程及分支的显微解剖可避免术中损伤眼动脉。
Objective To provide some microsurgical anatomy for operations related to the ophthalmic artery. Methods We examined twenty adult cadaveric heads under ×5 to 25 magnification. The microsurgical anatomy of the origin,course and branches of the ophthalmic artery was studied. Results 90% ophthalmic artery originated from the supraclinoid segment of the internal carotid artery (ICA),most of them arose from the medial third of the superior surface of the ICA. 5% ophthalmic artery originated from the cavernous segment of ICA. 5% ophthalmic artery originated from the middle meningeal artery. The ophthalmic artery was divided into three segments (intracranial,intracanal and intraorbital segment). According to the relation to the optic nerve,the intraorbital course of the ophthalmic artery was divided into three parts. The main branches of ophthalmic artery included central retinal artery,posterior ciliary artery,lacrimal artery,posterior and anterior ethmoidal arteries. Conclusion The ophthalmic artery can be protected in operation if we are familiar with the microsurgical anatomy of the origin,course and branches of the ophthalmic artery.
