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.
