Venous anastomoses at the base of the brain are represented by the anterior and posterior communicating veins. The anterior communicating vein anastomoses with the anterior communicating vein anastomoses with the anterior cerebral veins. The posterior communicating veins join the basal veins through the interpenduncular veins. The functional value of these venous anastomoses is less important than that of the arterial polygon of Willis. This anastomotic function depends on anatomical constancy and on the calibre of these transverse veins. Under certain pathological conditions the variations of intracranial pressure result in contralateral venous drainage through these anterior and posterior anastomotic veins.
脑底部的静脉吻合由前交通静脉和后交通静脉代表。前交通静脉与大脑前静脉吻合。后交通静脉通过脚间静脉汇入基底静脉。这些静脉吻合的功能价值不如 Willis 动脉环重要。这种吻合功能取决于解剖学上的恒定以及这些横静脉的管径。在某些病理情况下，颅内压的变化会导致通过这些前后吻合静脉进行对侧静脉引流。
