Obstetrical and Fertility Outcomes Following Transcatheter Pelvic Arterial Embolization for Postpartum Hemorrhage: A Cohort Follow-Up Study.

Objectives: Management of severe postpartum hemorrhage (PPH) includes transcatheter pelvic arterial embolization (TAE). Data regarding subsequent fertility and obstetrical outcomes is limited, as most fertility outcomes derive from TAE in uterine fibroma. The purpose of our study was to evaluate the long-term outcomes of patients undergoing TAE, particularly concerning subsequent fertility and following pregnancies. Material and methods: We included 28 patients who underwent TAE for PPH at our institution between 2009 and 2018 in a retrospective cohort study. Data were assessed by reviewing patients' charts and by contacting the patients. Results: Ten patients had prophylactic balloon occlusion before cesarean section because of anticipated PPH, with planned hysterectomy by placenta increta/percreta. All these patients were excluded from the analysis regarding fertility. 16 (73%) patients reported having regular menstruation after TAE. In total, 11 women had no desire for subsequent pregnancy. Seven of the remaining 11 patients (63.6%) had a total of 13 spontaneous pregnancies, nine of these resulted in miscarriages. Four patients delivered a live baby (36.4%). Two of these (50%) had recurrent PPH and treatment was conservative. Of the patients with infertility (n = 4, 36.4%), two (18.1%) underwent assisted infertility treatment without success. Conclusion: Our study suggests that the fertility of patients undergoing TAE due to PPH is limited. In women who conceive, the risk for first trimester miscarriage as well as recurrent PPH seems to be increased. If this is a consequence of the underlying cause of PPH or the TAE remains unknown. Larger follow-up cohorts are needed. In the meantime, patients who desire pregnancy after TAE should be counseled accordingly.
