Endovascular treatment of vein of Galen aneurysmal malformation.
A vein of Galen aneurysmal malformation represents an arteriovenous fistula draining in a dilated precursor of the vein of Galen. We report a case of an incidentally detected large aneurysmal malformation of the vein of Galen in a 25-year-old man.The malformation was visualized with CT, MRI and digital subtraction angiography.This uncommon vascular malformation is rarely detected in adults as symptoms usually arise during childhood. This patient had no neurological complaints but the angiography showed, however, a steal phenomenon from the anterior circulation. The lesion was treated with good results by means of endovascular embolization with coils.
