| 摘 要： | 本文观测了25例(50侧)颈内动脉的岩段和海绵窦段。岩段可分为垂直部与水平部,两部移行处称岩段的膝。岩段垂直部无分支发出,水平部发出翼管动脉和骨膜支。另外指出了凿开颞骨岩部颈动脉管前壁,以暴露颈内动脉的外科途径。海绵窦段可分为后升部、水平部、前升部及后曲、前曲等部。海绵窦段的主要分支是脑膜垂体干和海绵窦下动脉。本文还报道了1例少见的残留性三叉动脉。

| Abstract: | The petrous and the cavernous segments of 50 internal carotid arteries were examined in 25 adult cadavers.The petrous segment was divided into two portions, namely,the vertical portion and the horizontal portion.The two portions joined at the genu.No branch was found on the vertical portion.The horizontal portion sent off the pterygoid artery and the periosteal artery.Moreover,a surgical approach to the petrous segment of the internal carotid artery was explained. The cavernous segment was divided into the posterior acscending portion,hori- zontal portion,anterior ascending portion,posterior curve and anterior curve.The cavernous segment sent off two main branches,namely,the meningohypophyseal trunk and the artery of the inferior cavernous sinus.Moreover,a rare case of the persistent trigeminal artery was reported. |
