Intravascular ultrasound (IVUS) is used as a diagnostic adjunct to angiography and has become a valuable diagnostic and interventional tool with a well-documented safety profile. The American College of Cardiology and the European Society of Cardiology have published guidelines regarding the use of IVUS in the setting of percutaneous coronary intervention. IVUS has gained popularity in the interventional radiology (IR) community in recent years; however, there are no consensus guidelines for utilization. Furthermore, IVUS remains an infrequently used modality in pediatric IR, likely because of unfamiliarity with the equipment and techniques, as well as concerns over the compatibility of these instruments with pediatric anatomy. IVUS can be safely used as a helpful and sometimes necessary tool for pediatric interventions in appropriately selected patients. The utility of IVUS for reducing both fluoroscopy time and contrast agent volume makes it particularly valuable in pediatric practice. This article presents an overview of both the rotational and phased-array IVUS types and an in-depth discussion on the most common applications of these techniques in the pediatric setting across multiple procedure categories.
血管内超声（IVUS）用作血管造影的辅助诊断工具，具有良好的安全性记录，已成为一种有价值的诊断和介入工具。美国心脏病学会和欧洲心脏病学会已经发布了关于在经皮冠状动脉介入治疗中使用 IVUS 的指南。近年来，血管内超声在介入放射学（IR）领域越来越受欢迎；然而，目前还没有关于其使用的共识指南。此外，血管内超声在儿科 IR 中仍然是一种使用频率较低的方法，这可能是由于对设备和技术不熟悉，以及对这些仪器与儿科解剖结构的兼容性的担忧。在适当选择的患者中，血管内超声可以安全地用作一种有帮助且有时必要的工具进行儿科介入治疗。血管内超声可减少透视时间和造影剂用量，因此在儿科实践中特别有价值。本文介绍了旋转和相控阵 IVUS 两种类型，并深入讨论了这些技术在儿科多个手术类别中的常见应用。
