Cerebral venograms of 21 clinical cases of midline anomalies of the brain and of 80 human fetuses between 3 and 8 months old were examined. The diagnostic value of the venogram was fully proven, particularly for the midline cerebral anomalies, where deep cerebral structures and configuration of the tentorium cerebelli were not well visualized by other neuroradiologic maneuvers. Abnormal structures of the deep cerebral veins as well as the dural sinuses in these malformations were proved to retain the venous structures in the early fetal period. The time of formation of these malformations was also inferred from the viewpoint of the venous development. Study of the fetal venous system was found quite useful for embryologic analysis and classification of congenital malformations of the brain.
对21例脑中线异常的临床病例以及80例3至8个月大的人类胎儿的脑静脉造影进行了检查。静脉造影的诊断价值得到了充分证实，特别是对于脑中线异常，在这种情况下，其他神经放射学检查方法无法很好地显示大脑深部结构和小脑幕的形态。这些畸形中大脑深部静脉以及硬脑膜窦的异常结构被证明在胎儿早期保留了静脉结构。还从静脉发育的角度推断了这些畸形的形成时间。发现研究胎儿静脉系统对先天性脑畸形的胚胎学分析和分类非常有用。
