Abstract

The benefits of a cardiac resynchronization therapy (CRT) implantation are known in severe heart failure and its implantation may also be considered during pregnancy to ensure safe pregnancy and delivery for both the mother and the fetus. This study on a patient case aimed to estimate the absorbed dose (AD) to the fetus during the CRT implantation of 21st week of the pregnant woman. AD measurement was done using anthropomorphic phantom, radiophotoluminescence dosemeters and Monte Carlo simulation utilizing kerma area product (KAP) of the procedures. The measured AD for a phantom's uterus and heart was 0.116 and 14.7 mGy with total KAP of 27.9 Gycm2. The estimated actual AD to the fetus and the mother's heart was 0.004 and 1.2 mGy, with total KAP of 1.5 Gycm2. The dose to the fetus can be minimized with the optimized procedure.

孕期植入 CRT 起搏器：胎儿辐射剂量估算。

众所周知，心脏再同步化疗法（CRT）植入对严重心力衰竭患者有好处，在怀孕期间也可考虑植入，以确保母亲和胎儿的安全妊娠和分娩。本研究针对一例患者，旨在估算孕妇在第 21 周植入 CRT 时胎儿的吸收剂量（AD）。吸收剂量的测量采用了拟人化模型、放射光剂量计和蒙特卡洛模拟，利用的是手术过程中的切口面积乘积（KAP）。测得的模型子宫和心脏的 AD 分别为 0.116 和 14.7 mGy，总 KAP 为 27.9 Gycm2。估计胎儿和母亲心脏的实际 AD 分别为 0.004 和 1.2 mGy，总 KAP 为 1.5 Gycm2。通过优化程序，可将胎儿所受剂量降至最低。

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
