斑块脱出穿过细胞支架被认为是颈动脉支架术后远端栓塞术的主要原因之一。卡斯珀支架(日本东京Terumo)是具有双层结构的最新一代支架，有望降低栓塞风险。患者男，76岁，无症状，左侧颈内动脉高度狭窄，行颈动脉支架植入术。术前磁共振成像在T1加权图像上显示非常高的信号。在预扩张后，卡斯珀支架具有双层设计结构，在外部闭孔支架上编织了内部镍钛微网，然后进行后扩张。术后光频成像显示外支架与血管壁贴合良好，内微网支架间无明显斑块脱出。支架置入术后，MRI未发现缺血性病变，也未发现异常的神经系统表现。
Plaque prolapse through the cell stent has been suggested as one of the major causes of postprocedural distal embolization after carotid artery stenting. A CASPER stent (Terumo, Tokyo, Japan) is the latest-generation stent having the dual layers and expected to reduce the risk of embolization. A 76-year-old male asymptomatic patient with high-grade stenosis in the left internal carotid artery received carotid artery stenting. Preoperative magnetic resonance imaging demonstrated very high intensity signals on T1-weighted images. After a predilatation, a CASPER stent, which has a dual-layer design construction with an inner nitinol micromesh woven onto an external closed-cell stent, was deployed followed by postdilatation. Postprocedural optical frequency domain imaging revealed good apposition of the outer stent to the vascular wall and no significant prolapse of plaque materials between the struts of the inner micromesh. No ischemic lesions were identified on MRI and no abnormal neurological findings were noted after stenting.
