The venous return of the cerebral hemispheres is ensured by two systems. The first, superficial system, reaches the peripheral dural sinuses, i.e. the superior sagittal sinus, the lateral sinus and the cavernous sinus. The second, deep system, corresponds to Galen's vein. Anatomical and angiographic data from the literature enable the usual drainage territory to be defined for each of these collecting vessels. However, the variability of the superficial sylvian vein and the importance of cortical anastomotic vessels make impossible to delimit precisely the territory of each peripheral sinus. The functional role played by numerous centro-peripheral anastomoses is more difficult to assert in each individual. It is therefore probable that in the cerebral hemispheres there is a deep territory balancing the superficial territories.
大脑半球的静脉回流由两个系统保障。第一个是浅表系统，通向周围的硬脑膜窦，即上矢状窦、外侧窦和海绵窦。第二个是深部系统，对应于大脑大静脉。文献中的解剖学和血管造影数据能够为这些收集血管中的每一个确定通常的引流区域。然而，大脑外侧浅静脉的变异性以及皮质吻合血管的重要性使得难以精确界定每个周围窦的区域。众多中央-外周吻合支所起的功能作用在个体中更难确定。因此，大脑半球很可能存在一个深部区域来平衡浅表区域。
