Abstract
INTRODUCTION: Fetal spina bifida (SB) repair is a distinct therapeutic option in selected cases. Since this procedure may not only be associated with short-term obstetrical complications, the aim of this study was to assess the outcomes of subsequent pregnancies after open fetal SB repair.
METHODS: 138 patients having had open fetal SB repair at our center received a questionnaire regarding the occurrence, course, and outcome of subsequent pregnancies. Additionally, medical records were reviewed. All subsequent pregnancies with complete outcome data that progressed beyond 20 gestational weeks (GW) were included for further analysis.
RESULTS: 70% of all women answered the questionnaire. Out of this cohort, 35 subsequent pregnancies were reported in 29% of women. The rate of early pregnancy loss including elective terminations was 14%. All 29 pregnancies processing >20 GW ended in live births without preterm births <34th GW. Mean gestational age at delivery was 37.3 ± 1.4 GW. Uterine rupture occurred in two cases (7%) and uterine thinning/dehiscence was present in six cases (21%). No maternal transfusions were required.
CONCLUSION: When counseling women undergoing open fetal SB repair, one should consider possible risks for subsequent pregnancies, especially the one of uterine dehiscence and rupture that is similar compared to numbers reported after classical cesarean deliveries.
