EARLY PRENATAL DOPPLER US DIAGNOSIS OF GIANT VEIN OF GALEN ANEURYSM CAUSING EARLY NON-IMMUNE HYDROPS-FETALIS

Purpose: Aneurysms of vein of Galen are rare intracranial malformations of the cerebral arteriovenous malformations. In the literature the diagnosis of fetal brain AVMs has been limited to case reports diagnosed usually after 30 weeks of gestation. We present a early diagnosed case of giant vein of Galen aneurysm in a fetus of a 27 weeks of gestation with cardiovascular decompensation.
