目的研究展神经脑桥池段与邻近血管的关系,为有关疾病诊治提供相关解剖学基础。方法采用23例(46侧)红色乳胶灌注的头颅标本,解剖与观测展神经脑桥池段走行、与周围血管关系、滋养血管来源等,测量数据统计处理。结果展神经脑桥池段邻近的血管包括小脑下前动脉、小脑下后动脉、迷路动脉、椎动脉、基底动脉、脑桥动脉。小脑下前动脉与展神经关系最为密切(47.8%接触,13.8%压迫),椎基底动脉压迫展神经最严重。展神经脑桥池段的滋养动脉主要来自脑桥动脉(41.3%),其次为小脑下前动脉(26.1%);16侧(34.8%)展神经为复式。结论展神经脑桥池段与邻近血管的关系复杂,血管易于接触并压迫展神经,临床上不明原因的展神经麻痹应考虑存在此类血管压迫的可能。
Objective To study the relationship between the pontine pontine segment and adjacent blood vessels and to provide relevant anatomical basis for the diagnosis and treatment of related diseases. Methods 23 cases (46 sides) of red latex perfusion skull specimens were dissected and observed. The anatomic and observational data were processed by statistical analysis. Results The nerves near the Patellar segment include the inferior cerebellar artery, the posterior inferior cerebellar artery, the labyrinth artery, the vertebral artery, the basilar artery, and the pons artery. The inferior cerebellar artery has the closest relationship with the dorsal nerve (47.8% contact, 13.8% oppression), vertebrobasilar artery compression is the most serious nerve. Nerve pontine nostril artery segment mainly from the pons artery (41.3%), followed by the inferior cerebellar artery (26.1%); 16 (34.8%) show the nerve complex. Conclusions The relationship between the pontine pontine segment and the adjacent vessels is complicated. The vessels are easy to contact with and compress the dorsal nerves. Clinical unexplained neurological paralysis should consider the possibility of such vascular compression.
