摘要
目的 :为蝶鞍区肿瘤手术提供垂体动脉的显微外科解剖学资料。方法 :采用显微解剖技术对17个甲醛固定、红色明胶动脉灌注的成年尸头标本的垂体上动脉和垂体下动脉进行观察。结果 :垂体上动脉主要起自颈内动脉床突上段的内侧壁或内下壁 ,发起后向内、向上斜行 ,直至垂体柄 ,行程中可分支至视神经、视交叉 ,起始部直径为 (0 .2± 0 .1)mm。垂体下动脉起自脑膜垂体干 (94.1% )或直接起自颈内动脉 (5 .9% ) ,发起后沿颈内动脉内侧前行 ,再穿出海绵窦内侧壁自鞍底至垂体 ,起始部直径为 (0 .8± 0 .2 )mm。结论 :鞍区肿瘤手术应注意垂体上、下动脉的走行特点 ,并保护好这些动脉 ,以减少手术并发症的发生。
Objective:To provide the microanatomic data for tumorectomy in sella turcica region.Methods:The superior and interior hypophyseal arteries of 17 adult cadaveric brain specimens were observed under anatomic microscope.Results:The superior hypophyseal artery arose from the medial or medial inferiror wall of the supraclinoid portion of internal carotid artery.The arterial stem went into pituitary stalk and some small branches to optic nerve and chiasm.Its original diameter was 0.2±0.1mm.Inferior hypophyseal artery came from meningeal hypophyseal stem (94.1%) or from carotid artery(5.9%).It went through the medial of internal carotid artery,and perforated internal wall of cavernous sinus into pituitary.Conclusion:When tumorectomy was performed in sella turcica region,superior and inferior hypophyseal arteries must be protected.
