摘　　要：目的　研究三叉神经与小脑上动脉之间的关系。　方法　解剖尸体头颅 2 0例 4 0侧 :打开颅盖 ,去除大脑组织并打开小脑幕 ,观察三叉神经和小脑上动脉之间的关系并测量两者之间的距离 ,观察小脑上动脉的走行。　结果　本组与三叉神经最近的血管均为小脑上动脉 ,二者距离 0～ 8 1mm ,平均 2 19mm。 4 0侧小脑上动脉均发出分支 ,4 7 5 % (19/ 4 0 )的小脑上动脉与三叉神经相交 ,87 5 % (35 / 4 0 )的小脑上动脉主干和分支的结合处距离三叉神经最近。　结论　小脑上动脉可发出嘴侧和尾侧 2个分支 ,小脑上动脉主干和分支的结合处距离三叉神经最近。Objective To study the relation between the trigeminal nerve and the superior cerebellar artery. Methods The authors dissected 20 cadaver skulls (40 sides):we firstly opened the calvaria and cleaned the cerebrum, then opened the tentorium of cerebellum and observed the relation between the trigeminal nerve and the superior cerebellar artery, as well as measured the distance between them, finally inspected the trend of the superior cerebellar artery. Results In the study the nearest blood vessel to the trigeminal nerve was the superior cerebellar artery, with a distance of 0～8 1 mm (mean, 2 19 mm). All the superior cerebellar arteries had rostral and caudal branches. Approximate 47 5% of the superior cerebellar arteries (19/40) crossed with trigeminal nerves, and in 87 5% of the superior cerebellar arteries (35/40) the closest site to the trigeminal nerve was the junction of the main trunk and the rostral or caudal branches. Conclusions The superior cerebella artery usually gives off rostral and caudal trunks. The junction of the main trunk and the rostral or caudal branches is nearest to the trigeminal nerve.
