Treatment of vein of Galen aneurysmal malformation.

The authors report the case of a vein of Galen aneurysmal malformation in a 1-year-old baby presenting with an enlarging head. The lesion was a direct arteriovenous fistula in a dilated vein of Galen and was treated by complete embolization in one session. Four months after occlusion of the shunt, the ectatic vein of Galen and torcular were normal, and the head circumference had stabilized. This case serves as an opportunity to emphasize the quality of results that can be obtained with endovascular techniques. Proper analysis of the vein of Galen angioarchitecture allows planning for appropriate treatment with the lowest possible risk of morbidity and mortality.
