Intravascular ultrasound (IVUS) is a useful diagnostic method that provides valuable information in addition to angiography regarding the coronary vessel lumen, dimensions, plaque burden, and characteristics. The major use of IVUS in coronary intervention is to guide interventional strategies and assess optimal stent deployment. Since the introduction of the drug-eluting stent (DES), concerns about restenosis have decreased. However, high-risk lesion subsets are being routinely treated with DESs, and the incidence of suboptimal results after stent deployment, such as stent underexpansion, incomplete stent apposition, edge dissection, geographic miss, and the risk of stent thrombosis, have correspondingly increased. Thus, optimization of stent deployment under IVUS guidance may be clinically important. In this review, we focus on the potential role of IVUS in stent optimization during percutaneous coronary intervention and its clinical benefits.
血管内超声（IVUS）是一种有用的诊断方法，除了血管造影外，它还提供了有关冠状动脉管腔、尺寸、斑块负荷和特征的有价值的信息。IVUS 在冠状动脉介入中的主要用途是指导介入策略和评估最佳支架置入。自从药物洗脱支架（DES）问世以来，对再狭窄的担忧已经减少。然而，高风险病变亚组通常用 DES 治疗，支架置入后不理想的结果（如支架扩张不足、支架贴壁不良、边缘夹层、地理缺失和支架血栓形成的风险）的发生率相应增加。因此，在 IVUS 指导下优化支架置入可能具有重要的临床意义。在这篇综述中，我们重点介绍 IVUS 在经皮冠状动脉介入治疗中优化支架的潜在作用及其临床获益。
