A Patient with Carotid Mobile Plaques Treated by Carotid Artery Stenting Using a Double-layer Micromesh Stent

抄録

Objective: We report a case of carotid mobile plaques treated by carotid artery stenting (CAS) using a double-layer micromesh stent (CASPER stent).

Case Presentation: An 86-year-old male presented with lightheadedness. Carotid artery ultrasound revealed mobile plaques in the right internal carotid artery (ICA). Head and neck MRI demonstrated concomitant left ICA occlusion. We first started medical treatment, but it could not reduce the plaque size. Then, we performed CAS using a CASPER stent in addition to medical treatment. The procedure was finished without complications, and there was no plaque protrusion. The postoperative course was uneventful during 3 years of follow-up.

Conclusion: A mobile plaque of the carotid artery may be treated less-invasively with a micromesh stent.
