Three-dimensional computed tomography (3D CT) angiography was used to investigate two cases of persistent primitive arteries. 3D CT angiography and 3D CT demonstrated a persistent primitive trigeminal artery variant penetrating the lateral edge of the posterior clinoid process and running to the posterior medial side, and a persistent primitive trigeminal artery perforating the canal of the posterior clinoid process and the petrosal bone junction. 3D CT angiography can delineate these persistent primitive arteries and the anatomy relative to the bone structure simultaneously, so is very useful to identify the arterial line where the canal is penetrated.
采用三维计算机断层扫描（3D CT）血管造影术对2例持续性原始动脉病例进行研究。3D CT血管造影和3D CT显示，一种持续性原始三叉动脉变异体穿透后床突外侧缘并向后内侧走行，另一种持续性原始三叉动脉穿过后床突与岩骨交界处的管道。3D CT血管造影能够同时描绘出这些持续性原始动脉及其与骨结构相关的解剖结构，因此对于识别管道被穿透的动脉走行非常有用。
