Stent migration after carotid artery stenting in long-term period: A rare complication Stent migration after carotid artery stenting

Stent migration is a rare complication of carotid artery stenting (CAS) and maypresent with ischemic stroke. A 71-year-old male patient with symptomatic left carotid stenosis was treated with CAS. The patient had a transient ischemic attack with mild weakness in the right upper extremity eight months later. Computed tomography angiography showed severe stenosis in the cervical ICA next to the stent. Downward migration of the stent on left ICA with about 50% stenosis next to the stent was seen in DSA. Another stent was placed from the cervical segment of ICA to CCA, covering the stenotic lesion.
