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.
我们报告了一例罕见的颈动脉支架置入并发症，表现为颈动脉Wallstent的金属环标记移位导致支架部分展开，从而阻碍了支架的完全扩张。腔内锁定的颈动脉支架使患者必须紧急接受颈动脉内膜切除术。这种不寻常并发症的一个可能原因可能是制造缺陷，据我们所知，此前在公开数据库或互联网上均未记录过此类情况。
