血管外科手术中的术中成像技术
近年来,血管内技术在血管外科医生的日常实践中占据了重要地位。这些技术的微创性和吸引力,以及日益高效的导航设备和成像诊断系统的改进,使这成为可能。在现有的成像技术中,主要有两类:第一类是辐照技术,它将亮度放大器、平面传感器和混合室组合在一起,需要很好地掌握辐射防护原理和对比产品管理;第二类是生态多普勒的非辐照技术,血管内超声(IVUS)、光学相干断层扫描(OCT),还有磁共振(MRI)和正在评估的新设备,包括增强现实。涉及主动脉的血管内手术需要使用术前三维重建软件和术中软件,前者允许进行干预计划,后者便于手术并减少X射线曝光率和干预时间,特别是通过使用图像融合。必须掌握这些技术的知识,因为它们是血管外科有效实践不可或缺的工具。
