Abstract:
A 59-year-old man presented with acute onset of visual loss in his right eye. He was treated under a diagnosis of retinal artery thrombosis. Ultrasonography revealed obstruction of the ipsilateral internal carotid artery (ICA). He had no risk factor for stroke and he denied any history of trauma. Follow-up ultrasonography obtained 6 months later showed spontaneous ICA recanalization. Cerebral angiography demonstrated an arterial wall flap suggesting ICA dissection at the craniocervical junction. He then remembered suffering hemicranial headache and Horner's sign of several days' duration after jumping off a stepladder 1 year earlier. The present case is quite unusual in that persistent carotid arterial wall dissection was thought to proceed to ICA obstruction and manifested as retinal ischemia after a long asymptomatic period.
