case_images: Transcranial Doppler ultrasonography (TCD) confirmed occlusion of the distal portion of the left ICA and showed signs of collateralization to the right carotid territory via the ipsilateral posterior communicating artery (Fig. 1).

case_images: Cerebral angiography showed total occlusion of the left internal carotid artery with multiple leptomeningeal collateral vessels of the left posterior cerebral artery filling retrogradely the territory of the left middle cerebral artery

case_images: f2-1337-1-10162-1-10-20191122
case_images: Cerebral angiography was performed and confirmed the findings of total occlusion of the left ICA with multiple leptomeningeal collateral vessels of the left posterior cerebral artery filling retrogradely the territory of the left MCA (Fig. 2).
case_images: Cerebral angiography revealed right internal carotid artery occlusion after the emergence of the anterior choroidal artery and an abnormal network of transdural collateral vessels that filled retrogradely the territory of the right middle and anterior cerebral arteries

case_images: Furthermore, cerebral angiography revealed right ICA occlusion after the emergence of the anterior choroidal artery and an abnormal network of transdural collateral vessels that filled retrogradely the territory of the right MCA and ACA (Fig. 3).
