RT Journal Article SR Electronic T1 A Rare Complication of Carotid Artery Stenting: Displacement of Marker Ring Causing Locking of Stent and Incomplete Stent Expansion JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1403 OP 1404 DO 10.3174/ajnr.A0562 VO 28 IS 7 A1 Akgul, E. A1 Aksungur, E.H. A1 Korur, K. A1 Aikimbaev, K. A1 Yaliniz, H. YR 2007 UL http://www.ajnr.org/content/28/7/1403.abstract AB SUMMARY: We present a rare case of a complication of placement of a carotid artery stent represented by partial opening of a carotid Wallstent caused by displacement of its metal ring marker, which thus hindered complete expansion of the stent. An intraluminally locked carotid stent necessitated referral of the patient for urgent carotid endarterectomy. A possible reason of this unusual complication can be a manufacturing defect, which, to our knowledge, was not documented previously in open public data bases or on the Internet.
