A 41-month-old boy was presented to our hospital because of an intracranial mass suspected of cerebrovascular malformation. He was admitted and received cerebral angiography. The angiography result confirmed the intracranial mass was the dilated vein of Galen resulting from a pial arteriovenous fistula, which quite resembling the vein of Galen aneurysmal malformation. Considering one-time embolization of the fistula may greatly change the distribution of intracranial blood flow, we decided to perform staged embolization. In the first stage, we partially embolized the fistula, resulting in a sharp decrease in blood flow to the lesion. The second intervention was performed one month later, and completely embolized the fistula. The boy recoverd well and returned to normal childhood without any neurological deficits. Follow-up MR images obtained at 10 months after the last procedure showing total obliteration of the pAVF, gradually shrinking of the varix, and remodeling of the vein of Galen.
一位 41 个月大的男孩因疑似脑血管畸形的颅内肿块就诊于我院。他入院并接受了脑血管造影。造影结果证实颅内肿块为大脑大静脉扩张，由软脑膜动静脉瘘引起，与大脑大静脉动脉瘤样畸形非常相似。考虑到一次性栓塞瘘可能会极大地改变颅内血流分布，我们决定分期栓塞。在第一阶段，我们部分栓塞瘘，使病变的血流量急剧减少。第二个干预措施是在一个月后进行的，完全栓塞了瘘。该男孩恢复良好，回到了正常的童年生活，没有任何神经功能缺损。最后一次手术后 10 个月的随访 MR 图像显示动静脉瘘完全闭塞，静脉瘤逐渐缩小，大脑大静脉重塑。
