(a) Lateral angiogram of the common carotid artery (CCA) showing occlusion of the ICA. (b) Lateral CCA angiogram: exclusive filling of the intracranial vessels through multiple collaterals (), retrogradely filled ophthalmic artery (OA); arrows depict a connection between the middle meningeal artery (MMA) and OA. Dural anastomoses from MMA to ICA at the level of the skull base (); arrow heads depict a branch of the sphenopalatine artery feeding the cavernous ICA (superimposed by the superficial temporal artery). (c) Lateral angiogram after intervention: (TICI3). Vessel wall irregularities are rated as atherosclerotic.
