Clinical Course and Management of Vein of Galen Varix of the Neonate: A Case Report and Literature Review

Abstract

A 28-year-old pregnant woman underwent an emergency caesarian section after 39 weeks of gestation because of decreased fetal movement and baseline fetal heart rate variability. The neonate was diagnosed with neonatal asphyxia and presented with right cardiac failure due to pulmonary hypertension. The neonate presented convulsion, and plane computed tomography (CT) showed dilation of the vein of Galen and sinuses on day 3. Magnetic resonance imaging and CT with contrast were performed after cardiac failure subsided, and there was no evidence of arteriovenous shunt and normalization of the vein of Galen. The patient was diagnosed with vein of Galen varix (VGV). In the previous literature, only 3 cases of VGV have been reported. VGV is considered to be caused by right cardiac failure without the presence of an arteriovenous shunt and requires treatment only for cardiac failure and its cause. Therefore, it is important to differentiate VGV from vein of Galen aneurysmal malformation.
