Endovascular aortic repair has transformed the treatment of aortic pathologies, providing minimally invasive alternatives to traditional open surgery. Despite these advancements, endovascular procedures continue to encounter substantial challenges, including navigating tortuous and calcified vessels, precise catheterization of the aortic branch vessels in complex cases, and the significant risks of radiation exposure to both patients and operators. Recent innovations in electromagnetic (EM) tracking and 3D imaging offer a promising alternative to traditional methods. This review focuses on the Intraoperative Positioning System (IOPS), a novel EM-based image guidance system developed by Centerline Biomedical, Inc. (Cleveland, OH). IOPS uses sensorized, EM-tracked devices to enhance procedural precision and safety by minimizing reliance on ionizing radiation while improving visualization and the accuracy of catheterization in vascular anatomies. This technology enables parts of the procedure to be performed without the need for ionizing radiation, offering a safer and more efficient approach to endovascular procedures.
血管内主动脉修复术改变了主动脉疾病的治疗方式，为传统开放手术提供了微创替代方案。尽管有这些进展，但血管内手术仍面临重大挑战，包括在迂曲和钙化血管中导航、在复杂病例中精确插入主动脉分支血管的导管，以及患者和操作人员遭受辐射的重大风险。电磁（EM）跟踪和3D成像方面的最新创新为传统方法提供了一种有前景的替代方案。本综述重点关注术中定位系统（IOPS），这是由中心线生物医学公司（俄亥俄州克利夫兰）开发的一种基于电磁的新型图像引导系统。IOPS使用带有传感器的电磁跟踪设备，通过减少对电离辐射的依赖，同时改善可视化和血管解剖结构中导管插入的准确性，来提高手术精度和安全性。这项技术使部分手术无需电离辐射即可进行，为血管内手术提供了一种更安全、更高效的方法。
