In the past decades, we have witnessed tremendous developments in endovascular surgery. Nowadays, highly complex procedures are performed by minimally invasive means. A key point is equipment improvement. Modern C-arms provide advanced imaging capabilities, facilitating endovascular navigation with an adequate open surgical environment. Nevertheless, radiation exposure remains an issue of concern. This study aims to analyze radiation used during endovascular procedures according to complexity, comparing a mobile X-ray system with a hybrid room (fixed X-ray system). This is an observational and prospective study based on a cohort of non-randomized patients treated by endovascular procedures in a Vascular Surgery department using two imaging systems. The study is planned for a 3-year duration with a recruitment period of 30 months (beginning 20 July 2021) and a 1-month follow-up period for each patient. This is the first prospective study designed to describe the radiation dose according to the complexity of the procedure. Another strength of this study is that radiologic variables are obtained directly from the C-arm and no additional measurements are required for feasibility benefit. The results from this study will help us determine the level of radiation in different endovascular procedures, in view of their complexity.
在过去几十年里，我们见证了血管内手术的巨大发展。如今，高度复杂的手术通过微创方式进行。一个关键点是设备的改进。现代C形臂提供了先进的成像能力，在有足够开放手术环境的情况下便于血管内导航。然而，辐射暴露仍然是一个令人担忧的问题。本研究旨在根据手术复杂性分析血管内手术期间的辐射情况，比较移动X射线系统和混合手术室（固定X射线系统）。这是一项基于血管外科使用两种成像系统对非随机患者队列进行的观察性前瞻性研究。该研究计划为期3年，招募期为30个月（从2021年7月20日开始），每位患者有1个月的随访期。这是第一项旨在根据手术复杂性描述辐射剂量的前瞻性研究。本研究的另一个优势是放射学变量直接从C形臂获得，无需额外测量即可获得可行性益处。鉴于不同血管内手术的复杂性，本研究结果将有助于我们确定其辐射水平。
