Radiation exposure and the effect of anti-scatter grids are not well studied in premature infants during transcatheter patent ductus arteriosus closure.This study aimed to investigate whether the use of anti-scatter grids altered the level of radiation exposure to premature infants undergoing transcatheter patent ductus arteriosus closure.
Demographic and radiation exposure data for premature infants who underwent transcatheter patent ductus arteriosus closure at the Stead Family Children's Hospital from 10/2019 to 10/2021 were retrospectively reviewed and analyzed. Twenty-four patients (41%) underwent transcatheter patent ductus arteriosus closure with anti-scatter grids, while 34 (59%) underwent the procedure without using anti-scatter grids. At the time of catheterization, the median age, corrected age, and weight were 4.3 weeks (3.4-6), 29 weeks (28.1-30.9), and 1200g (1000-1600), respectively. Total radiation exposures for the dose area product and air kerma were 2.73 µGy.m (1.65-4.16), and 1.63 mGy (1.15-2.58), respectively. Radiation doses were higher in the group in whom the anti-scatter grids were utilized with dose area product of 3.33 µGy.m (2.39-5.43) and air kerma of 2.27 mGy (1.41-3.06) versus 1.86 µGy.m (1.46-3.60) and air kerma of 1.40 mGy (1.08-1.92). When radiation doses were adjusted to the radiation time, no difference in radiation exposure was noticed between the groups.
Transcatheter patent ductus arteriosus closure in premature infants can be safely performed with minimal radiation exposure. In the authors' laboratory, the use of anti-scatter grids does not impact radiation exposure in premature infants.
在早产儿经导管动脉导管未闭封堵术中，辐射暴露及防散射格栅的影响尚未得到充分研究。本研究旨在调查使用防散射格栅是否会改变接受经导管动脉导管未闭封堵术的早产儿的辐射暴露水平。
回顾性分析了2019年10月至2021年10月在斯特德家庭儿童医院接受经导管动脉导管未闭封堵术的早产儿的人口统计学和辐射暴露数据。24例患者（41%）在经导管动脉导管未闭封堵术中使用了防散射格栅，而34例（59%）未使用防散射格栅进行该手术。在导管插入时，中位年龄、矫正年龄和体重分别为4.3周（3.4 - 6周）、29周（28.1 - 30.9周）和1200克（1000 - 1600克）。剂量面积乘积和空气比释动能的总辐射暴露分别为2.73µGy·m（1.65 - 4.16）和1.63mGy（1.15 - 2.58）。使用防散射格栅的组辐射剂量更高，剂量面积乘积为3.33µGy·m（2.39 - 5.43），空气比释动能为2.27mGy（1.41 - 3.06），而未使用组分别为1.86µGy·m（1.46 - 3.60）和空气比释动能为1.40mGy（1.08 - 1.92）。当将辐射剂量调整为辐射时间时，两组之间未发现辐射暴露差异。
早产儿经导管动脉导管未闭封堵术可在最小辐射暴露下安全进行。在作者的实验室中，使用防散射格栅不会影响早产儿的辐射暴露。
