Stable value of WSS along the vessel wall in the cerebrovenous system. According to whether the WSS along different walls has statistical discrepancy, the walls of cerebrovenous system were divided into three groups: 1 SSD (downstream wall of SSS from the dural entrance) and SSO-D (opposite and downstream wall of SSS from the dural entrance), 2 BVU (upstream wall of BV from the dural entrance) and BVD (downstream wall of BV from the dural entrance), 3 SSU (upstream wall of SSS from the dural entrance) and SSO-U (opposite and upstream wall of SSS from the dural entrance)
