EP08.08: Vein of Galen aneurysmal malformation: a case report

Report on a prenatal venous malformation of Galen diagnosis. A descriptive study of a case of venous malformation of Galen diagnosis. We report the case of a pregnant woman of 34 weeks, with no obstetric or personal family history of interest. She was derived from a private clinic due to the obstetric ultrasound finding of the third trimester of the ventriculomegaly. A new ultrasound was performed showing an aneurysm of the vein of the physician with right-sided cardiomegaly, severe tricuspid regurgitation and reverse ductus wave. Subsequently, a magnetic resonance was performed confirming the diagnosis. The family finally decided to interrupt without trying prenatal therapies due to the poor prognosis. Subsequently, the autopsy informed of an aneurysmal Vein dilatation of Galen associated to signs of congestive heart failure. The venous malformation of Galen is a rare anomaly of the intracranial circulation that constitutes 1% of all intracranial vascular malformations and represents 30% of the vascular malformations in the pediatric age. It is a rare fetal anomaly, whose prognostic and clinical management factors have been studied in fetal series that are too small to allow reliable statistical evaluation. Paladini D. et al (2017) reports, after an observational study, that the main brain lesions, tricuspid regurgitation and, to a lesser extent, the volume of VGAM ≥ 20,000 mm3 are the only prenatal variables associated with the poor outcome in VGAM fetal. Prenatal multidisciplinary counselling and management should be based on these variables.
