Abstract

Objectives: There are no data describing the correlation between placenta implantation at prior myomectomy locations and perinatal outcomes in pregnant women after transcervical resection myomectomy (TCR-M). The aim of the study is to investigate the correlations between placenta implantation at prior myomectomy locations and perinatal outcomes in pregnant women who had previously undergone TCR-M. Materials and Methods: This was a retrospective, single-center study. We reviewed the records of 34 pregnant women who had previously undergone TCR-M for submucosal myoma and perinatal care in our hospital between January 2012 and January 2019. We examined surgical and pregnancy outcomes and evaluated correlations between placenta implantation at prior myomectomy locations and perinatal outcomes in women who delivered after 22 gestational weeks (n = 24). Results: Median maternal age at conception was 38 years (range, 28-44) and median duration between TCR-M and conception was 1.4 years (range, 0.3-5.8). There were 24 deliveries after 22 gestational weeks and 10 pregnancy losses. Among these 24 deliveries, the median gestational age at delivery was 39 weeks (range, 34-41); median birthweight, 3025 g (range, 2092-4012); and median blood loss at delivery, 573 g (range, 100-3000). There were no cases of placenta accreta and uterine rupture. Placenta implantation at a prior myomectomy location was detected in 14/24 women using transabdominal ultrasonography. Median blood loss was significantly higher in the implantation than in the nonimplantation group (P < 0.01). Conclusion: Our one-step TCR-M is useful for women with submucosal myoma. However, we suggest that clinicians should review and check the association between prior myomectomy locations and placenta implantation.
