摘　　要：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 superficial middle cerebral veins (SMCV) of 50 human heads were dissected under the operating microscope (10×). There were 122 terminal braches of the SMCV in the specimens and the types of their drainage can be divided into four:type 1 (41.00%)—drains into the caver- nous sinus;type 2 (24.60%)—drains into the variant venous sinus in the lateral wall of the cavernous sinus;type 3(28.70%)—drains into the variant venous sinus in the dura of the middle cranial fossa;type 4(5.70%)—drains into other dural venous sinuses.Type 1 may be considered as normal and the others as variant. The two variant dural venous sinuses reported are respectively located in the lateral wall of the cavernous sinus,named“the lateral wall sinus of the cavernous sinus”,and in the dura of the middle cranial fossa,named the“variant sinus of the middle cranial fossa”.The former occurred 27% in the specimens and the later 25%. We have discussed about the drainage of the SMCV and two variant dural ven- ous sinuses on the embryonic basis and the clinical practice.
