Abstract

Retained neuroprotection filter after carotid stenting (CAS) is an extremely rare complication. We report the
case of a 61-year old patient with an accidentally retained neuroprotection filter after urgent CAS. The patient
did not consent to open surgical removal of the retained basket. We did not observe any flow disturbances in
the filter and the patient remains asymptomatic in ten years follow-up. In some cases, the neuroprotection
filter left in the internal carotid artery may not cause cerebral flow disturbances or occlusion of the stent. In
case of the poor neurological or general condition of the patient, we can wait for its improvement or stenting.
