“…Here we present a series of cases of prenatal diagnosis of GVA based on ultrasonography at an average gestational age of 25 weeks; our diagnosis agrees with the findings reported in most publications. [8][9][10] Magnetic resonance imaging is used to evaluate associated neurological findings that may be of prognostic value. In our case series, MRI showed no diagnostic advantages over ultrasonography.…”

Objective To describe the prenatal diagnosis of Galen vein aneurysm (GVA) based on ultrasonography and magnetic resonance imaging (MRI) in a series of cases, as well as its postnatal outcomes and follow-up until 4 years of age. Methods A retrospective longitudinal study was performed, analyzing a database comprising seven cases of prenatal diagnosis of GVA at two Brazilian institutions from February of 2000 to May of 2012. The following data were evaluated: gestational age at diagnosis, GVA dimensions on ultrasonography, associated fetal changes, findings on fetal echocardiography, gestational age at delivery, type of delivery, birth weight, Apgar score at the 1st and 5th minutes, neonatal outcomes, and survival with follow-up until 4 years of age. Results The mean gestational age AE standard deviation on the prenatal diagnosis of GVA based on ultrasonography was 25 AE 4.9 weeks. The mean length of GVA was 3.2 AE 0.4 cm. The mean gestational age at birth was 37.5 AE 0.7 weeks, and a cesarean section was performed in 85.7% of the cases (6/7). The mean birth weight was 3,070 AE 240.4 g. The total survival rate was 42.8% (4/7), with three neonatal deaths. Of the four survivors, three presented with normal neuropsychomotor development until 4 years

“…7 Other prenatal diagnostic methods such as ultrasonography in the 3-dimensional power Doppler mode have been described, but these have shown no advantages over conventional ultrasonography and MRI. 8,9 Fetal echocardiography may help detect early signs of heart failure, which, together with hydrops, is the most common consequence of GVA.…”

“…They are very rare and constitute 1% of all intracranial vascular malformations and can cause severe morbidity and mortality; particularly in the neonatal period . The vein of Galen aneurysm produces a large systemic shunt causing changes in the cardiovascular system, which include pulmonary hypertension, right to left atrial shunting through the foramen ovale and cardiomegaly …”

Background AV malformation of the vein of Galen, also known as vein of Galen aneurysm, is an intracranial anomaly characterised by a midline, high flow lesion with a complex vascular architecture. It compromises less than 1% of all cerebral arteriovenous malformations seen in adults and children. Timely diagnosis of the malformation is of importance particularly during the perinatal period due to the large systemic shunting within the fetal brain potentially leading to cardiac failure, hydrops and perinatal death. Method Case Report: In this report, we present a case that had an increased nuchal translucency of 6 mm at 12 weeks gestation (karyotype normal), nuchal oedema of 12 mm noted at morphology scan and subsequently diagnosed with vein of Galen malformation at 32 weeks on a follow up scan. It was evaluated further with 3D power Doppler imaging modality. 3D power Doppler imaging provided us with improved images of the malformation in utero which was helpful for characterising the vascular anatomic features of the lesion before planned delivery and neonatal treatment. Results The patient was followed up with antenatal ultrasounds. There was no evidence of hydrops. She delivered a live healthy infant weighing 2.8 kg by elective caesarean section at 39 weeks. The child is now five and half years old and has undergone embolisation twice. Conclusion We present a case illustrating use of Power Doppler imaging in a vein of Galen malformation. Prenatal diagnosis and endovascular treatment in the early neonatal period is important in preventing heart failure and resultant mortality in vein of Galen aneurysm.
