Vein of Galen aneurysmal malformations. Report of 36 cases managed between 1982 and 1988.

Abstract：

:The authors report a series of 36 vein of Galen aneurysmal malformations (VGM) diagnosed in the paediatric (78%) and adult (22%) populations that were referred to them for therapeutic management between 1982 and 1988. The clinical signs leading to the diagnosis were variable: 36% of systemic manifestations, 22% of neurological symptoms, 17% of hydrocephaly and 11% of intracranial haemorrhage. 30 angioarchitectural analyses could be obtained and allowed to classify these VGMs into 5 different types: 44% parenchymatous AVMs, 20% mural AVFs, 30% choroidal arteriovenous fistulas, 3% dural AVFs, 7% vein of Galen varices. This series demonstrates that the paediatric population is most sensitive to shunt effect whatever its type. Systemic manifestations and hydrocephaly are the most common signs encountered in the newborn and infants; whereas neurological signs and symptoms and haemorrhage belong mostly to the adult symptomatology. Because of the poor outcome of VGMs, all authors believe that these malformations have to be treated aggressively. However, we found contra-indications to be represented by pretherapeutic demonstration of cerebral tissue damage, or uncontrollable systemic failure, thus treatment is indicated to compensate for cardiac failure previously responding (even partially) to medical treatment. Secondly, appearance of sub-cortical calcifications, resistance to medication or clinical deterioration will also lead to urgent treatment. The endovascular method represents at present the best treatment with an overall low mortality (13%) and a 0% technical morbidity in children compared to the surgical one of (91% mortality in newborns and 38% in infants). The results achieved by embolization in this series were as follows: 27% satisfactory results with complete or almost complete occlusion of AV Shunt, 53% significant clinical improvement, 7% of patients were unchanged. The authors believe fundamentally that these patients (specially those belonging to the paediatric population) have to be treated in a centre where a paediatric intensive care unit, neurological, neurosurgical and surgical neuro-angiographic departments coexist, in order to assure the best possible management of these children.
