Percutaneous interventions help patients with various cardiovascular diseases, however radiation exposure is a safety concern for both patients and health care providers. We previously reported that dose area product (DAP) is apparently different in central body and upper-limb areas during percutaneous transluminal angioplasty for arteriovenous shunt dysfunction. In this study, we investigated the precise radiation dose at the patients' back and at the non-targeted organs of the operators.
The radiation dose was measured with optically stimulated luminescent dosimeters and DAP on several sites including the backs of the patients, gonads, hands and lens of the operators. The studied populations were categorized into central, upper arm and forearm groups based on the lesion sites.
The results indicated that there was a significantly higher radiation dose in the central lesion group than in the upper arm and forearm groups. Conversely, there were no specific differences in total procedure time and fluoroscopy time among groups. The radiation exposure doses in the operators showed that regardless of the site, including lens, hands and gonads of the operators, the radiation dose was significantly higher in the central lesion group.
The closer the lesion site to the body center, the higher the radiation exposure in both the patients and operators.
经皮介入治疗有助于患有各种心血管疾病的患者,然而辐射暴露对患者和医护人员来说都是一个安全问题。我们之前报道过,在经皮腔内血管成形术治疗动静脉分流功能障碍期间,剂量面积乘积(DAP)在身体中心部位和上肢部位明显不同。在本研究中,我们调查了患者背部和操作者非靶向器官的精确辐射剂量。
使用光激发发光剂量计和DAP在包括患者背部、性腺、操作者手部和晶状体在内的多个部位测量辐射剂量。根据病变部位将研究人群分为中心组、上臂组和前臂组。
结果表明,中心病变组的辐射剂量显著高于上臂组和前臂组。相反,各组之间的总手术时间和透视时间没有具体差异。操作者的辐射暴露剂量显示,无论操作者的部位是晶状体、手部还是性腺,中心病变组的辐射剂量都显著更高。
病变部位离身体中心越近,患者和操作者的辐射暴露就越高。
