Thromboembolic complications after carotid artery stenting (CAS) remain an unsolved problem, and several intravascular imaging tools have been proposed to clarify the mechanism of these complications. We report a case of intraprocedural plaque protrusion revealed by angioscopy. A 64-year-old woman underwent CAS for left carotid artery stenosis. After stent placement, optical frequency domain imaging demonstrated some plaque protrusion, and angioscopy showed prominent mobile plaque fragments protruding into the vessel between stent struts and confirmed the coverage of the protruded plaque after the overlapping stent was placed. Compared with other tools, angioscopy more clearly revealed plaque protrusion in the vessel after CAS.
颈动脉支架置入术后（CAS）的血栓栓塞并发症仍然是一个未解决的问题，已经提出了几种血管内成像工具来阐明这些并发症的发生机制。我们报告了一例血管镜检查发现的术中斑块突出病例。一名 64 岁女性因左侧颈动脉狭窄而行 CAS 治疗。支架置入后，光频域成像显示有一些斑块突出，血管镜检查显示突出的斑块碎片明显移动，突出进入支架支柱之间的血管内，并确认在重叠支架放置后突出斑块的覆盖情况。与其他工具相比，血管镜更清楚地显示了 CAS 后血管内的斑块突出。
