One-year evaluation of the treatment of hydrocephalus associated with Galen’s vein aneurysm: about 3 cases in a country with limited health resources

Abstract

Aneurysm of vein of Galen is a rare congenital arteriovenous malformation. Clinical manifestations depend on the age of discovery. Endovascular embolization is currently the treatment of choice. This technique is not always available in developing countries. We report 3 cases treated symptomatically by endoscopic third ventriculostomy and ventriculoperitoneal shunt. Three patients, 7 months, 15 years, and 26 years old, received in a table of acute intracranial hypertension, associated for the first one with convulsions and for the second one with moderate heart failure. Bain CT scan revealed triventricular hydrocephalus secondary to sacciform dilatation of the Galen’s vein in all three patients, requiring symptomatic treatment by endoscopic third ventriculostomy for the first patient and ventriculoperitoneal shunt for the other two in the absence of an adequate clinical platform for endovascular embolization. The evolution was favorable at 1 year’s follow-up. Galen’s vein aneurysm is a rare vascular malformation. It mainly affects newborns and small children but can be discovered in adulthood. Endovascular embolization is its treatment of choice. This technique is not always available in some countries, which makes it necessary to resort to symptomatic treatment by ventricular shunt.
