摘要
目的 :探讨垂体柄的显微外科解剖特点和显露垂体柄的显微外科技术。方法 :在 1 5例 (30侧 )经颈内动脉灌注红色乳胶的成人尸体头颅上模拟翼点入路 ,借助手术显微镜在 6～ 2 5倍下通过鞍区手术间隙对下垂体柄显微解剖。结果 :经翼点入路 ,通过鞍区的手术间隙可对垂体柄进行良好的显露。垂体柄的主要血管为垂体上动脉 ,平均每侧有 1 .8支 ,平均直径为 (0 .33±0 .0 2 ) mm ,它分为烛台型和单支型。结论 :经翼点入路对鞍区病变 ,特别是颅咽管瘤显微手术时 ,可利用垂体柄的解剖特点 。
Objective:To study the microsurgical anatomy and microsurgical techniques of exposure the pituitary stalk.Methods:The pituitary stalk and its arteries were examined via pterional approach from the operating spaces in sellar region in 15 formalin fixed adult cadaveric heads in which the arteries were perfused with red silicone.An 6 to 25 power neurosurgical operating microscope was used for all dissection.The superior hypophyseal arteries(SHA) were microanatomized and measured in isolated brains.Result:The pterional approach can provide excellent exposure for the pituitary stalk from the operating spaces in sellar region. The SHA are the main arteries of the pituitary stalk which urises from the medial aspect of the ophthalmic segment of the internal carotid artery in a candelabra type or a single branch type.There was an average of 1.8 SHA arising from each carotid artery with an average outer diameter of (0 33±0 02) mm.Conclusion:In the microsurgical management of lesion in the sellae region such as craniopharyngioma via pterional approach,the pituitary stalk could be identified according its microsurgical anatomic features especially the SHA and should be manipulated carefully with microsurgical techniques.
