摘要:
目的测定小儿先天性室间隔缺损(VSD)介入治疗中患者辐射剂量;分析影响X线辐射剂量的因素及其减低剂量方法。方法2008年12月-2009年10月,应用热释光测量法对30例小儿先天性VSD介入治疗患者进行辐射测量,热释光剂量仪(TLD)贴在儿童患者相应体表处,结果分别代表晶状体、甲状腺、照射野和性腺处的皮肤受照剂量。结果晶状体、甲状腺、照射野和性腺4点的平均皮肤受照剂量分别是(65.7±48.8)μGy ,(2618.2±862.6)μGy ,(3376.5±838.4)μGy 和57.0μGy ,透视时间平均(7.2±3.0)min,造影曝光时间平均(6.1±1.8)s。结论经导管介入治疗VSD是一种安全和疗效可靠的方法,但儿童患者对辐射更加敏感。小儿VSD介入治疗照射剂量最大区域是照射野,其次是甲状腺,应控制照射野大小,加强对甲状腺区域的防护,尽量减少电离辐射对儿童健康的影响。
