摘　　要：目的研究睫状后动脉的显微解剖结构。方法选取30例(60侧)头颅标本进行血管灌注红、蓝乳胶或硅橡胶,对睫状后动脉的起源、分支、走行及毗邻关系等进行观察和测量。结果睫状后动脉起自眼动脉第1段、眼动脉角、眼动脉第2段、眼动脉弯、眼动脉第3段。睫状后动脉分支形式分为内外侧和内外上侧2种类型,内外侧型最常见。睫状后动脉内侧支主要起始于眼动脉弯,外侧支和上侧支主要起始于眼动脉角。内、外、上侧支的直径分别为(0.71±0.24)mm、(0.69±0.22)mm、(0.63±0.19)mm。结论睫状后动脉的起始及眶内走行变异多,掌握睫状后动脉的解剖结构有助于减少术中出血及损伤,避免视神经缺血引起的视力丧失。Objective To investigate the microscopic anatomic structures of posterior ciliary arteries.Methods Thirty cranium specimen（60 sides） were selected to take vascular perfusion of red emulsion,blue emulsion or silicone rubber.The origin,branches,courses and adjacent structures of the posterior ciliary artery were observed and measured.Results Posterior ciliary arteries derived from the 1st ophthalmic artery segment,the angle of the ophthalmic artery,the 2nd ophthalmic artery segment,the ophthalmic artery bend and the 3rd ophthalmic artery segment.The patterns of branching of the posterior ciliary arteries were medial-lateral and medial-lateral-superior.The most frequently observed posterior ciliary artery was medial-lateral pattern.Medial posterior ciliary artery derived from ophthalmic artery bend.Lateral and superior posterior ciliary arteries derived from ophthalmic arteries angle.The diameters of medial,lateral and superior posterior ciliaries artery were（0.71±0.24）mm,（0.69±0.22）mm and （0.63±0.19）mm,respectively.Conclusions The variations in origin and course of posterior ciliary arteries are much.The anatomical study of the posterior ciliary arteries can reduce bleeding and injury in operation and avoid the loss of vision caused by ischemia of optic nerve in rabbits.
