3D reconstruction of CTA showing<unk>  of<unk> <unk> <unk>  often lead to cardiac failure, cranial bruits (pattern 1), hydrocephaly, and subarachnoid hemorrhage in neonates. The heart failure is due to the size of the arteriovenous shunt that can steal 80% or more of the cardiac output, with large volumes of blood under high pressure returning to the right heart and pulmonary circulation and sinus venosus atrial septal defects. It is also the most common cause of death in such patients. Associated conditions Non-developmental syndromes also directly or indirectly affect the Great Cerebral<unk>  of<unk> , although they are extremely rare. These include superior vena cava syndrome (SVCS), and thrombosis of the lateral sinus, superior sagittal sinus, internal jugular<unk> , or of the Great Cerebral<unk>  of<unk>  itself.
