Because of the increasing number of interventional endovascular procedures with fluoroscopy and the corresponding high annual dose for interventionalists, additional dose-protecting measures are desirable. The purpose of this study was to evaluate the effect of disposable radiation-absorbing surgical drapes in reducing scatter radiation exposure for interventionalists and supporting staff during an endovascular aneurysm repair (EVAR) procedure.
This was a randomized control trial in which 36 EVAR procedures were randomized between execution with and without disposable radiation-absorbing surgical drapes (Radpad: Worldwide Innovations & Technologies, Inc., Kansas City, US, type 5511A). Dosimetric measurements were performed on the interventionalist (hand and chest) and theatre nurse (chest) with and without the use of the drapes to obtain the dose reduction and effect on the annual dose caused by the drapes.
Use of disposable radiation-absorbing surgical drapes resulted in dose reductions of 49%, 55%, and 48%, respectively, measured on the hand and chest of the interventionalist and the chest of the theatre nurse.
The use of disposable radiation-absorbing surgical drapes significantly reduces scatter radiation exposure for both the interventionalist and the supporting staff during EVAR procedures.
由于介入血管内手术中透视的数量不断增加，介入医生的年剂量相应增加，因此需要采取额外的剂量保护措施。本研究旨在评估在血管内动脉瘤修复（EVAR）手术中使用一次性辐射吸收手术巾对减少介入医生和手术室护士散射辐射暴露的效果。
这是一项随机对照试验，将 36 例 EVAR 手术随机分为使用和不使用一次性辐射吸收手术巾（Radpad：Worldwide Innovations & Technologies，Inc.，美国堪萨斯城，类型 5511A）进行。在使用和不使用手术巾的情况下，对介入医生（手部和胸部）和手术室护士（胸部）进行剂量测量，以获得手术巾所带来的剂量减少和对年度剂量的影响。
使用一次性辐射吸收手术巾可使介入医生手部和胸部以及手术室护士胸部的散射辐射暴露量分别减少 49%、55%和 48%。
在 EVAR 手术中使用一次性辐射吸收手术巾可显著减少介入医生和手术室护士的散射辐射暴露。
