Abstract:
Objective To evaluate the current radiation doses in pediatric non-cardiac interventional procedures, and analyze the associated clinical factors, and to provide data references for reducing pediatric radiation exposure. Methods We conducted a retrospective analysis of the radiation doses of children who had undergone non-cardiac interventional procedures at the interventional department of a tertiary pediatric hospital in Jinan from January 2022 to October 2024. The collected data included basic demographic information, surgical date, anatomical site, disease type, and radiation dose parameters (cumulative fluoroscopy time, cumulative dose area product in cine mode, cumulative air kerma, and the number of images acquired). The Kruskal-Wallis H test was used for comparative analysis between groups (P < 0.05 was considered statistically significant). Results Among the 475 included children, 99 cases (20.8%) had infantile hemangioma (median Pka, 0.136 Gy·cm2; median Ka,r, 0.38 mGy), 235 cases (49.5%) had venous malformation (median Pka, 9.82 Gy·cm2; median Ka,r, 40.99 mGy), 75 cases (15.8%) had lymphatic malformation (median Pka, 0.06 Gy·cm2; median Ka,r, 0.18 mGy), 32 cases (6.7%) had retinoblastoma (median Pka, 6.58 Gy·cm2; median Ka,r, 52.34 mGy), 12 cases (2.5%) had arteriovenous malformation (median Pka, 42.3 Gy·cm2; median Ka,r, 162.87 mGy), and 22 cases (4.6%) had other vascular malformations (median Pka, 21.7 Gy·cm2; median Ka,r, 89.1 mGy). There were significant differences between children with different disease types in the cumulative fluoroscopy time, cumulative dose area product in cine mode, cumulative air kerma at the patient entrance reference point, and the number of images acquired during non-cardiac interventional procedures (all P < 0.01). Conclusion This study presented the types and proportions of pediatric non-cardiac interventional procedures, evaluated the radiation dose levels of different surgical types, and analyzed the effects of weight and anatomical site on radiation exposure, which can be useful for preliminary assessment of radiation doses in pediatric non-cardiac interventional procedures.
