The trans-cerebral v. have long been described, but there is little or no knowledge of their function and dysfunction. They are the site of fundamental interchange across the blood-brain barrier, a unique process within the organism. Two systems can be structurally distinguished: the venous system draining the white matter and the trans-cerebral anastomotic system. The former seems to be associated with the nutrition and drainage of the parenchyma, and is rendered visible at angiography by anatomic variations based on developmental venous anomalies. The anastomotic trans-cerebral ventriculo-cortical system seems concerned with the regulation of reabsorption of the cerebrospinal fluid. It is visualized only in exceptional situations where an increased flow (arteriovenous shunt) is combined with obstruction of the normal routes of venous drainage and collateral circulation. It usually functions in the ventriculo-cortical direction. No specific dysfunction of this system is currently recognized.
经大脑静脉早就被描述过，但对其功能和功能障碍知之甚少。它们是跨越血脑屏障进行根本交换的部位，是机体中的独特过程。在结构上可区分出两个系统：引流白质的静脉系统和经大脑吻合系统。前者似乎与实质的营养和引流有关，在血管造影中通过基于发育性静脉异常的解剖变异而显现。吻合性经大脑脑室 - 皮质系统似乎与脑脊液重吸收的调节有关。它仅在异常情况下可见，即血流量增加（动静脉分流）与正常静脉引流途径和侧支循环受阻同时存在时。它通常沿脑室 - 皮质方向发挥作用。目前尚未认识到该系统有特定的功能障碍。
