目的估算介入放射工作人员常见介入手术过程中眼晶状体受照剂量水平。方法选取常见血管内介入手术(脑血管造影、冠状动脉造影+支架置入、肝动脉化疗栓塞术,下肢血管造影术),手术者进行前,将已经准备好的片型热释光剂量计置于术者手术帽边缘靠近左眼处,进行测量。结果术者在不同类型介入手术一次手术过程中眼晶状体所受剂量存在差异,剂量最高者是冠状动脉支架植入手术,第一术者为(40.38±42.40)μGy,第二术者为(63.73±61.72)μGy;在同一台介入手术中,第二术者眼晶状体剂量往往高于第一术者;同一类型介入手术中眼晶状体所受剂量大小与手术中曝光时间长短存在正相关关系,相关系数r=0.469,P<0.01。结论在介入手术中,术者眼晶状体受到一定剂量的照射,而介入工作人员防护铅眼镜的佩戴率很低,因此必须重视眼睛的防护,加强防护管理,尽可能的减少介入工作人员工作中照射剂量。
OBJECTIVE: To estimate the exposure dose to the lens of the eye during interventional radiological interventions. Methods The common endovascular interventional procedures (cerebral angiography, coronary angiography + stent implantation, transcatheter arterial chemoembolization, and lower extremity angiography) were performed. Before the operation, the prepared thermoluminescence dose meter At the edge of the surgeon’s surgical cap near the left eye, measurements were made. Results There was a difference in the dosage of lens in one operation of different types of interventional surgery. The highest dosage was coronary artery stent implantation, the first operation was (40.38 ± 42.40) μGy, the second operation was (63.73 ± 61.72) μGy; in the same interventional surgery, the dosage of the second lens was higher than that of the first surgeon. In the same type of interventional surgery, there was a positive correlation between the dosage of the lens and the exposure time The coefficient r = 0.469, P <0.01. Conclusion In the interventional procedure, the lens of the surgeon is exposed to a dose of irradiation, and the lead-in staff interventional occupational lead wear rate is very low. Therefore, attention must be paid to the protection of the eye, strengthening of protection management and minimizing the exposure of the interventional workers dose.
