Abstract

Report of a study of the dynamic anatomy of the median suboccipital puncture of the cisterna magna cerebello medullaris, carried out on fresh cadavers. Direct inspection of the internal surface of the dura mater (DM) at the craniocervical region was possible by removing the calvarium and brain (sectioned at the upper cervical cord), during routine necropsies. Dislocation of the DM over the needle tip preceding dural penetration (so-called "dural tenting") was observed in all punctures (n = 30), measuring 3.12 (2.0-4.2) mm.

摘要

一项在新鲜尸体上进行的小脑延髓池枕下正中穿刺动态解剖学研究报告。在常规尸检过程中，通过移除颅骨和大脑（在颈髓上部切开），可以直接观察颅颈区域硬脑膜（DM）的内表面。在所有穿刺（n = 30）中均观察到硬脑膜在硬膜穿刺前针尖端上方的移位（所谓的“硬膜帐篷效应”），测量值为3.12（2.0 - 4.2）毫米。
