Coronary angiography has been considered the gold standard for the diagnosis of coronary artery disease and guidance of percutaneous coronary intervention (PCI). However, 2D-projection angiography cannot completely reflect the 3D coronary lumen. Intravascular ultrasound (IVUS) can overcome a number of limitations of coronary angiography by providing more information about the dimensions of the vessel lumen, plaque characteristics, stent deployment, and the mechanisms of device failure. Growing data from observational studies and randomized controlled trials have confirmed the clinical benefit of IVUS guidance during PCI. This article summarizes the evidence regarding IVUS guidance to highlight its advantages and to support the use of IVUS during PCI.
冠状动脉造影一直被认为是诊断冠状动脉疾病和指导经皮冠状动脉介入治疗（PCI）的金标准。然而，二维投影血管造影不能完全反映三维冠状动脉管腔情况。血管内超声（IVUS）可以通过提供更多关于血管管腔尺寸、斑块特征、支架植入以及器械故障机制等信息，克服冠状动脉造影的一些局限性。来自观察性研究和随机对照试验的越来越多的数据证实了PCI期间IVUS指导的临床益处。本文总结了有关IVUS指导的证据，以突出其优势并支持在PCI期间使用IVUS。
