Magnetic resonance imaging (MRI) showed multiple acute small embolic infarctions in the right frontal lobe (Fig. 1A). MR angiography revealed the right ICAO without the associated occlusion of the circle of Willis (Fig. 1B).

Common carotid angiography revealed a tapered occlusion of the cervical internal carotid artery (ICA) after the bifurcation (Fig. 2A). Vertebral angiography showed that the right ICA was patent distal to the posterior communicating artery (Fig. 2B). Aichi, Japan). A stent retriever (Solitaire X 6 x 40 mm; Medtronic, Minneapolis, MN, USA) was fully deployed from M1 to the ICA cavernous portion. After stent retrieval under continuous manual aspiration with the balloon-guiding catheter, we first confirmed ICA recanalization by vertebral angiography using a diagnostic catheter with the balloon inflated (Fig. 2C). Finally, internal carotid angiography revealed complete ICA recanalization (1 pass, TICI 3) and confirmed ophthalmic artery anterograde flow and retinal brush (Fig. 2D).
Fundus photography shows a cherry-red spot in the right eye, which confirmed CRAO.

Ophthalmoscopy carried out by an ophthalmologist and fundus photography revealed a cherry-red spot in the right eye, which confirmed CRAO (Fig. 3).
