摘要
血管内超声(intravascular ultrasound, IVUS)是一种基于导管的超声装置,能清晰显示血管的横断面,准确测量管腔数据,其衍生的虚拟组织学(virtual histology, VH)技术可以识别动脉粥样硬化斑块的组成并进行组织学分型。传统的依靠狭窄程度评价病变的技术在颈动脉支架置入术(carotid artery stenting, CAS)中存在局限性,而IVUS可以优化支架的选择和评估置入效果,从而改善治疗结果。IVUS在CAS术后并发症的预测方面也表现出良好的应用价值。本文通过对IVUS辅助CAS的研究进行回顾,综合分析IVUS在CAS中的应用。
Intravascular ultrasound (IVUS) is a catheter-assisted ultrasound device that is able to provide cross-section images of vessel, accurate measurement of lumen. The derived virtual histology (VH) technique is capable of evaluating tissue properties and different components can be visualized as different colors. Traditional technology that depends on stenosis degree to evaluate lesions has limitations in carotid artery stenting (CAS), while IVUS can optimize the selection of stents and evaluate the effect of stent implantation, improving the treatment outcome. IVUS is also valuable in predicting postoperative complications of CAS. This review is aimed to describe the progress on the application of IVUS in CAS.
