Abstract:
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.
摘要:
上矢状窦(SSS)包含在硬脑膜内,由大脑镰刀交界处的固有硬脑膜和骨硬脑膜组成,除了将镰刀附着在颅骨上。SSS从盲孔向前延伸,向后延伸到环形Herophili。大脑上静脉流入SSS,通过桥接静脉在外侧静脉腔下行进。大多数桥接静脉到达硬脑膜并直接进入SSS。然而,有些附着在硬脑膜上,或者在进入鼻窦之前存在一定距离。存在于硬脑膜中的桥接静脉和SSS之间的交界区的静脉结构称为硬脑膜静脉通道。SSS与连接脑膜和二倍体静脉的侧静脉腔隙连通,以及使者静脉。SSS的这些解剖变化是由矢状丛和边缘窦的融合和退出的胚胎学过程定义的。
