摘要

上矢状窦(SSS)位于硬脑膜内,硬脑膜由固有硬脑膜和位于大脑镰交界处的骨膜硬脑膜组成,此外还包括大脑镰与颅顶的连接处。SSS 从盲孔向前方延伸,向后方延伸至疝环。大脑上静脉流入 SSS,通过桥静脉从外侧静脉裂隙下方流过。大部分桥静脉到达硬脑膜后直接排入SS。然而,有些静脉附着在硬脑膜上,或在进入窦之前在硬脑膜上存在一段距离。存在于硬脑膜中的桥接静脉与SS 交界区的静脉结构被称为硬脑膜静脉通道。SSS 与连接脑膜静脉和二叶静脉的外侧静脉裂隙以及发射静脉相通。SSS 的这些解剖变化是由矢状神经丛和边缘窦的胚胎融合和退出过程决定的。

[Venous Anatomy of the Superior and Inferior Sagittal Sinuses].

The superior sagittal sinus(SSS)is contained within the dura, which consists of the dura propria and osteal dura at the junction of the falx cerebri, in addition to the attachment of the falx to the cranial vault. The SSS extends anteriorly from the foramen cecum and posteriorly to the torcular Herophili. The superior cerebral veins flow into the SSS, coursing under the lateral venous lacunae via bridging veins. Most of the bridging veins reach the dura and empty directly into the SSS. However, some are attached to the dural or existed in it for some distance before their sinus entrance. The venous structures of the junctional zone between the bridging vein and the SSS existed in the dura are referred to as dural venous channels. The SSS communicates with the lateral venous lacunae connecting the meningeal and diploic veins, as well as the emissary veins. These anatomical variations of the SSS are defined by the embryological processes of fusion and withdrawal of the sagittal plexus and marginal sinus.
