Successful carotid stenting for chronic total occlusion of the internal carotid artery.

A 64-year-old man complaining of pulsatile headache was admitted. Imaging studies revealed a near-total occlusion of the right proximal internal carotid artery (ICA) with slow antegrade flow into the distal ICA. Right cerebral flow was supplied by collateral flow through the posterior communicating and ophthalmic arteries. He was successfully treated by carotid artery stenting. No new neurological deficit or transient ischemic attack occurred after treatment.
