The authors demonstrated alternative ways of bloodflow from occluded superior sagittal sinus through hypertrophic dural veins (middle meningeal veins) and sphenoparietal sinus. Parameters of bloodflow were evaluated using triplex ultrasonography. The possibility of venous drainage into anterior segment of superior sagittal sinus proximal to the site of occlusion with further retrograde flow towards dural venous anastomosis is verified. Possibilities of spiral CT-venography and standard time-of-flight MR-venography for assessment of collateral venous flow were estimated.
作者展示了被阻塞的上矢状窦通过肥厚的硬脑膜静脉(脑膜中静脉)和蝶顶窦实现血流的替代途径。使用三维超声评估血流参数。证实了静脉血流入阻塞部位近端的上矢状窦前段并进一步向硬脑膜静脉吻合处逆向流动的可能性。评估了螺旋CT静脉造影和标准时间飞跃磁共振静脉造影用于评估侧支静脉血流的可能性。
