作者在肉眼和手术显微镜下解剖观察了50例(100侧)成人颅脑标本。大脑中浅静脉末段共有122支。其注入有较多变异,可分4型:Ⅰ型注入海绵窦(41.00%);Ⅱ型注入海绵窦侧壁窦(24.60%);Ⅲ型注入颅中窝异常窦(28.70%);Ⅳ型注入其他静脉窦(5.70%)。Ⅰ型与传统描述相似,为正常型,其他则为异常型。本文还报道了两种异常静脉窦:1.海绵窦侧壁窦位于海绵窦外侧壁内,出现率为27%;2.颅中窝异常窦位于颅中窝底的硬脑膜内,出现率为25%。本文还对大脑中浅静脉末段的注入,两种异常窦的发生和临床意义进行了讨论。
The authors dissected 50 adult (100-sided) adult brain samples under a macroscopic and surgical microscope. A total of 122 distal superficial cerebral venous. There were more variations in the infiltration of the cavernous sinus, which could be divided into four types: type Ⅰ into the cavernous sinus (41.00%), type Ⅱ into the cavernous sinus wall (24.60%), type Ⅲ into the skull antrum sinus (28.70% Into the other sinus (5.70%). Type I is similar to the traditional description, normal type, others are abnormal type. This article also reported two abnormal sinus: 1. Cavernous sinus lateral wall located in the lateral wall of the cavernous sinus, the incidence was 27%; 2. Abnormal midflexial sinus sinus skull midsole at the end of the dura mater, the incidence was 25%. This article also discusses the occurrence and clinical significance of the injection of distal superficial vein of the brain, two abnormal sinus.
