title: Dislodged self-expanding carotid stent delivery sheath marker ring leading to emergent surgery.
abstract: Endovascular carotid artery stenting has evolved over recent years to become a favorable alternative treatment option for cervical carotid artery stenosis. Potential complications include procedural embolism, carotid artery dissection, and hemodynamic instability. Events caused by device defect are unusual. We hereafter present a case in which the metallic marker ring on the delivery sheath dislodged and emergent surgery had to be performed to retrieve the locked stent.
