Prenatal diagnosis of a vein of galen aneurysm.
نویسندگان
چکیده
We present the prenatal diagnosis of a vein of Galen aneurysm in a 34-week fetus. The aneurysm was 8 x 3.5 x 3 cm in dimension, and located posterior to the third ventricle. Color flow examination revealed a turbulent flow in the lesion. There was significant cardiomegaly. Prenatal ultra-fast magnetic resonance imaging was used to view the malformation in three dimensions. Although the pregnancy continued uneventfully, the fetus died of congestive heart failure on the 3rd day postpartum. The value of antenatal sonography and magnetic resonance imaging in the prediction of prognosis is discussed.

Vein of Galen aneurysm is a rare congenital anomaly, originated from a defect in fusion of internal cerebral veins. Due to low resistance, it produces high debit cardiac insufficiency. It constitutes 1% of all intracranial vascular malformations. Prognosis depends on patient's age when the manifestation occurs and aneurysm size. The two reported cases are about fetal prenatal diagnosis of vein ...

Background: Vein of Galen aneurysm (VGA) is the most common form of symptomatic cerebrovascular malformation in neonates. It develops in a fetus in the first trimester of pregnancy due to unknown reasons, but it is likely to have a genetic etiology. The prognosis of VGA is usually poor, particularly in newborns with heart failure due to high-flow intracerebral shunt. Surgery and endovascular em...

Vein of Galen aneurysm malformation (VGAM) is a rare congenital vascular anomaly. Although the cause of VGAM remains to be elucidated, the current hypothesis is persistence of the embryonic vascular supply, which leads to progressive enlargement and formation of the aneurysmal component of a typical VGAM. Here, we present a 36-year-old woman at 23 weeks' gestation (gravida 3, para 2) who was ev...

Aneurism of the vein of Galen is a complex arteriovenous malformation which is of multiply communications between of the vein of Galen and the cerebral arteries. It represents less than 1% of the cerebral arteriovenous malformations. Few cases using three-dimensional (3D) power and color Doppler ultrasound have been reported in the literature. We present a case of an aneurysm of the vein of Gal...
