Recurrence and regression of the common carotid artery mobile plaque after stenting: case report

Abstract

Here, we describe a case of carotid artery stenting (CAS) for common carotid artery mobile plaque associated with ipsilateral retinal artery occlusion. The plaque recurred as a mobile protrusion after the first CAS. Deployment of the second overlapping stent was not able to cover the entire plaque either, but the plaque was immobilized. The plaque disappeared in 3 months under conservative therapy. Although the mechanisms of the mobile plaque regression after CAS remains to be elucidated, the unique clinical course of the present case may suggest healing process of the mobile plaque other than compression and coverage by the stent.
