2. Classifications * True vein of Galen aneurismal malformations * vein of Galen dilatations

3. Two subtypes * Choroidal form : fistula site 의 위치가 vein of Galen 의 앞쪽에 있으며 pericallosal artery, anterior choroidal artery(AChA),sub- apendymal branchs of the thalamoperforating vessels 이 main feeder 가 되며 대부분의 type 이 여기에 해당된다 . * mural type : fistula site 의 위치가 vein of Galen 의 뒤쪽에 있으며 shunt amount 가 적어서 나중에 증상이 나타난다
