Abstract
Aims: To evaluate the radiation exposure in pelvic artery embolization (PAE) with N-butyl cyanoacrylate (NBCA) used for controlling postpartum hemorrhaging.
Methods: This retrospective study included 65 consecutive PAE procedures for controlling hemorrhaging in 60 postpartum patients who underwent PAE at a single institution over the last five years. The 65 PAE procedures were divided into two groups: (i) the procedure with NBCA (NBCA group) and (ii) gelatin-sponge PAE with or without coil(s) (non-NBCA group). We compared mean numbers of embolized arteries, mean fluoroscopy time, and mean dose-area product (DAP) of the two groups.
Results: There were 36 (55.4%) and 29 (44.6%) procedures in the NBCA and non-NBCA groups, respectively. No significant differences in the clinical background and mean numbers of embolized arteries between the two groups were observed. The NBCA group had a shorter mean fluoroscopic time and a smaller mean DAP than the non-NBCA group (26.3±11.1 min versus 34.2±11.0 min, p = 0.011, and 43.5±19.5 Gy·cm2 versus 55.1±16.1 Gy·cm2, p = 0.003).
Conclusion: Pelvic artery embolization with NBCA is superior in reducing radiation exposure in patients with postpartum hemorrhaging.
