Collaterals in moyamoya disease. Lateral angiogram after common carotid injection in a 46-year-old female with advanced moyamoya disease, Suzuki stage 6. The internal carotid artery (ICA) is completely occluded above the origin of the ophthalmic artery (empty black arrow). Moyamoya lenticulo-striate vessels are regressing (arrowhead) and the cerebral circulation depends exclusively on collaterals. There are spontaneous transosseous anastomoses from the anterior branch of the superficial temporal artery (STA) to frontal cortical vessels (white arrow), anterior meningeal branches (black arrow) from the ophthalmic artery, and the middle meningeal artery (MMA) to the pericallosal and callosomarginal arteries in the parietal region (empty white arrow)
