目的:(1)观察寰枢关节旋转时椎动脉寰枢段的形态、行程的变化,测量寰枢关节与椎动脉的相互关系值。(2)解剖观察C1、C2颈神经的行程,探讨标本神经的标记方法,并分析寰枢关节旋转时可能导致的C1、C2颈神经行程变化。(3)通过三维CT诊断寰枢关节不全脱位的临床研究,探讨寰枢关节不全脱位的临床诊断与治疗方法选择。方法:(1)从本院PACS中选择需除外头颈部血管疾病而行CTA扫描检查的资料(对颈部旋转无明显异常临床检查患者按检查时段分成三组,每组检查时段约3个月,包括中立位及左、右旋转位进行容积扫描)中,选出椎动脉无明显病变的扫描资料159例,作为笔者的研究对象。研究对象年龄18-55岁,其中中立位...Objective: (1) To observe the morphological changes in atlantoaxial segment of vertebral artery, and measure the distances of atlantoaxial joint and vertebral artery, and to observe their variability. (2) To observe the course of C1, C2 nerve, and to explore the marking method about the specimen nerve, and analyse the course changes of C1, C2 nerve on the movement of atlantoaxial rotatory.
