DIAGNOSIS OF BRAIN VASCULAR MALFORMATIONS IN THE FETUS: Vein of Galen aneurysms can be diagnosed in utero. Other malformations are not seen. Ultrasound makes the diagnosis by showing a "cystic" structure in the posterior fossa. Colour Doppler shows the high flow.
The prognosis can be established by MRI. Bad prognosis factors are brain atrophy, cardiac insufficiency and complexity of the malformation. If these factors are absent, postnatal treatment by embolisation can be scheduled.
胎儿脑血管畸形的诊断：大脑大静脉动脉瘤可在子宫内诊断。其他畸形则无法看到。超声通过在后颅窝显示“囊性”结构来进行诊断。彩色多普勒显示高血流。
预后可通过磁共振成像（MRI）确定。不良预后因素包括脑萎缩、心脏功能不全和畸形的复杂性。如果不存在这些因素，可安排出生后进行栓塞治疗。
