In the past 30 y, the numbers and types of fluoroscopically-guided (FG) procedures have increased dramatically. The objective of the present study is to provide estimated radiation doses to physician specialists, other than cardiologists, who perform FG procedures. The authors searched Medline to identify English-language journal articles reporting radiation exposures to these physicians. They then identified several primarily therapeutic FG procedures that met specific criteria: well-defined procedures for which there were at least five published reports of estimated radiation doses to the operator, procedures performed frequently in current medical practice, and inclusion of physicians from multiple medical specialties. These procedures were percutaneous nephrolithotomy (PCNL), vertebroplasty, orthopedic extremity nailing for treatment of fractures, biliary tract procedures, transjugular intrahepatic portosystemic shunt creation (TIPS), head/neck endovascular therapeutic procedures, and endoscopic retrograde cholangiopancreatography (ERCP). Radiation doses and other associated data were abstracted, and effective dose to operators was estimated. Operators received estimated doses per patient procedure equivalent to doses received by interventional cardiologists. The estimated effective dose per case ranged from 1.7-56 μSv for PCNL, 0.1-101 μSv for vertebroplasty, 2.5-88 μSv for orthopedic extremity nailing, 2.0-46 μSv for biliary tract procedures, 2.5-74 μSv for TIPS, 1.8-53 μSv for head/neck endovascular therapeutic procedures, and 0.2-49 μSv for ERCP. Overall, mean operator radiation dose per case measured over personal protective devices at different anatomic sites on the head and body ranged from 19-800 (median = 113) μSv at eye level, 6-1,180 (median = 75) μSv at the neck, and 2-1,600 (median = 302) μSv at the trunk. Operators' hands often received greater doses than the eyes, neck, or trunk. Large variations in operator doses suggest that optimizing procedure protocols and proper use of protective devices and shields might reduce occupational radiation dose substantially.
在过去的 30 年中,荧光透视引导(FG)程序的数量和类型显著增加。本研究的目的是为非心脏病专家的医师提供执行 FG 程序的辐射剂量估计。作者在 Medline 上搜索了以英语发表的报告这些医师辐射暴露的期刊文章。然后,他们确定了几种主要的治疗性 FG 程序,这些程序符合特定标准:有至少五份关于操作者辐射剂量的已发表报告的明确程序、在当前医疗实践中经常进行的程序、以及纳入来自多个医学专业的医师。这些程序包括经皮肾镜碎石术(PCNL)、椎体成形术、骨科四肢骨折内固定、胆道程序、经颈静脉肝内门体分流术(TIPS)、头颈部血管内治疗程序和内镜逆行胰胆管造影(ERCP)。摘录了辐射剂量和其他相关数据,并估计了操作者的有效剂量。每个患者程序的操作者接受的估计剂量与介入心脏病专家接受的剂量相当。每个病例的估计有效剂量范围为 PCNL 为 1.7-56 μSv、椎体成形术为 0.1-101 μSv、骨科四肢骨折内固定为 2.5-88 μSv、胆道程序为 2.0-46 μSv、TIPS 为 2.5-74 μSv、头颈部血管内治疗程序为 1.8-53 μSv、ERCP 为 0.2-49 μSv。总体而言,在不同解剖部位的个人防护设备上测量的每个病例的操作者平均辐射剂量范围为眼部 19-800(中位数=113)μSv、颈部 6-1180(中位数=75)μSv和躯干 2-1600(中位数=302)μSv。操作者的手通常比眼睛、颈部或躯干接受更大的剂量。操作者剂量的巨大差异表明,优化程序方案以及正确使用防护设备和屏蔽物可能会大大降低职业辐射剂量。
