If an arterio-venous fistula exists, it balloons out to become the 'aneurysmal' [[vein of Galen malformation]]. This occurs since the vein is thin-walled, lies free within the subarachnoid space, and is unable to accommodate the arterial flow. median_prosencephalic_vein.txt Last modified: 2024/06/07 02:52by 127.0.0.1
