Endovascular Management of Vein of Galen Aneurysmal Malformations: A Retrospective Analysis over a 15-Year Period.

OBJECTIVES: This retrospective study was aimed at assessing our results of endovascular management in vein of Galen aneurysmal malformation (VGAM).

MATERIALS AND METHODS: This is a retrospective study of 26 patients of VGAM who underwent endovascular treatment between 1998 and 2012. All patients underwent trans-arterial embolization. Of 26 patients, 23 were treated using n -butyl cyano acrylate (Glue), while 3 out of 26 patients were treated using the ethylene vinyl alcohol (EVOH) copolymer.

RESULTS: Ages of the treated patients ranged from 1 day to 18 years of age. Of the patients treated, 17 were males and 9 were females. Around 15 of the VGAMs were of the mural variety and 11 were choroidal in nature. A good outcome was seen in 22/26 (85%) of the patients. Complications were seen in total in 7/26 patients (26.92%) of which 3/26 (12%) has a fatal outcome.

CONCLUSION: Endovascular embolization for VGAMs is highly efficacious and has helped create a population of VGAM survivors in this condition, which until only a few decades ago caused high mortality and morbidity.
