[目的]对比测定经股动脉和桡动脉路入途径行冠脉造影时第一术者手部的受照剂量,为心血管介入的辐射防护提供参考依据。[方法]在履行知情告知并尊重患者意愿的情况下,由经验丰富的心血管科介入专家左手背固定热释光剂量计,对体重和胸部体厚大致相同的60例男性患者行冠脉造影,按其血管途径分为桡动脉组32例和股动脉组28例,桡动脉途径组患者行Allen’s试验呈阳性,选右桡动脉入径;股动脉途径组按常规方法操作,采用热释光剂量仪分别测量不同途径下第一术者手部受照剂量。所得数据资料,采用SPSS10.0软件进行统计学分析,P﹤0.05为差异有统计学意义。[结果]两组造影途径的患者体重、胸部体厚、透视时间和曝光帧数没有明显差异,但术者手部剂量桡动脉组(54.65±48.18uGy)明显高于股动脉组(31.17±13.92uGy),两组结果进行比较,差异有统计学意义(P﹤0.05)。[结论]桡动脉途径因为成功率高、并发症少成为冠心病介入治疗的首选途径同时,介入医师所接受的辐射剂量较大,应该采取有效措施来加强对手术者和患者的辐射防护。
[Objective] To compare the dose of the first hand when coronary angiography was performed via femoral artery and radial artery, and to provide a reference for radiation protection of cardiovascular intervention. [Methods] With the help of informing and respecting patients’ wishes, 60 experienced male patients with cardiovascular diseases underwent coronary angiography According to their vascular pathways, they were divided into radial artery group (32 cases) and femoral artery group (28 cases). The patients in radial artery group were tested positive by Allen’s test and selected right radial artery. The femoral artery group was operated by conventional method, Dosimeters were measured in different ways under the first operator’s hand dose. The data obtained, using SPSS10.0 software for statistical analysis, P <0.05 for the difference was statistically significant. [Results] There was no significant difference in body weight, body thickness, time of fluoroscopy and exposure frames between the two groups. However, the hand-arm radial artery group (54.65 ± 48.18uGy) was significantly higher than the femoral artery group (31.17 ± 13.92 uGy), the two groups were compared, the difference was statistically significant (P <0.05). [Conclusion] Because of the high success rate and fewer complication of radial artery route as the preferred way of interventional therapy for coronary heart disease, the radiation dose received by interventional physicians should be larger. Therefore, effective measures should be taken to strengthen the radiation protection for the surgeons and patients.
