ABSTRACT
Background. Although radiation exposure is of great concern to expecting patients, little information is available on the fetal radiation dose associated with prophylactic internal iliac artery balloon occlusion (IIABO). Here we estimated the fetal radiation dose associated with prophylactic IIABO in Caesarean section (CS). Cases. We report our experience with the IIABO procedure in three consecutive patients with suspected placenta previa/accreta. Fetal radiation dose measurements were conducted prior to each CS by using an anthropomorphic phantom. Based on the simulated value, we calculated the fetal radiation dose as the absorbed dose. We found that the fetal radiation doses ranged from 12.88 to 31.6 mGy. The fetal radiation dose during the prophylactic IIABOs did not exceed 50 mGy. Conclusion. The IIABO procedure could result in a very small increase in the risk of harmful effects to the fetus.

Mentions: Figure 2 is a schematic of the X-ray tube image intensifier C-arm in relation to the phantom in the operating suite. The irradiation was carried out using a Siremobil Compact L C-arm (Siemens, Erlangen, Germany) or a GE-OEC 9800 C-arm (GE Healthcare, Buckinghamshire, UK) with last-image hold ability. The height of the operating table was leveled with the usual lithotomy position. The X-ray tube voltage and current used with the Siremobil Compact L C-arm were 106 kV and 3.1 mA, respectively. With the GE-OEC 9800 C-arm, the X-ray tube voltage and current were automatically regulated. The simulation results are shown in Tables 2 and 3.
