Yoshihara T, Okuda Y, Yoshino O. Association of congenital uterine anomaly with abnormal placental cord insertion and adverse pregnancy complications: a retrospective cohort study. J Matern Fetal Neonatal Med 2024; 37:2382309. [PMID: 39098848 DOI: 10.1080/14767058.2024.2382309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 06/17/2024] [Accepted: 07/15/2024] [Indexed: 08/06/2024]
Abstract
OBJECTIVE Congenital uterine anomalies during pregnancy increase the risk of pregnancy complications such as miscarriage, preterm delivery, fetal malpresentation, cesarean delivery, and fetal growth restriction. However, few studies have examined uterine anomalies in relation to perinatal complications other than those mentioned above. We investigated the association between pregnancies complicated by congenital uterine anomalies and various perinatal outcomes at our institution. METHODS This retrospective cohort study was conducted from January 2009 to May 2021. We included cases of uterine anomalies, such as septate, bicornuate, unicornuate, and didelphic uterus. First, the perinatal complications and neonatal outcomes were compared between pregnancies complicated by uterine anomalies and those with normal uteri. Second, we conducted an analysis based on the type of uterine anomalies classified into two groups: the minor anomaly group consisted of anomalies limited to the uterine cavity, such as the septate uterus, whereas the major anomaly group included anomalies affecting the uterine shape, such as bicornuate, unicornuate, and didelphic uterus. We compared the incidence of perinatal complications among the major anomaly, minor anomaly, and normal uterus groups. RESULTS During the study period, 45 pregnancies were complicated with uterine anomalies. The minor anomaly group included 11 patients and the major anomaly group included 34 patients. The incidence of fetal malpresentation was significantly higher in the uterine anomaly group than in the normal uterus group (18% vs. 3.7%, p = .04). Furthermore, the frequency of abnormal placental cord insertion was significantly higher in the uterine anomaly group (16% vs. 3.7%, p = .01). Examination based on the type of uterine anomaly revealed significant differences in cervical incompetence, malpresentation, cesarean section, and abnormal placental cord insertion. Cervical incompetence was more likely in patients with minor anomalies. In contrast, fetal malpresentation, cesarean section, and abnormal placental cord insertion were more likely in the major anomaly group. CONCLUSIONS In addition to the findings reported in previous studies, abnormal placental cord insertion was more frequent in pregnancies complicated by uterine anomalies.

Abstract
There is a prevailing opinion by gynecologists, much of it based on expert opinion or anecdotal evidence, that myomas are detrimental to pregnancy. Newer data challenge much of this dogma, but incorrect assumptions remain. Although not impeccable, multiple data address the correlation between myomas and reproduction, and some emerging evidence addresses surgical removal of these myomas and subsequent outcomes. A thorough literature search was performed, and the amassed data were analyzed to answer some of our most important queries about the role that myomas play in pregnancy and delivery. Uterine leiomyomas ultimately decrease in size during late pregnancy and postpartum. Spontaneous abortion rates are similar in women with and without leiomyomas. The data addressing leiomyoma effects on preterm prelabor rupture of membranes, placental abruption, cesarean delivery, and postpartum hemorrhage rates are conflicting, but the best evidence does not show a significant correlation compared with women without myomas. Preterm delivery rates are elevated in women with leiomyomas. Myomectomy does not decrease preterm deliveries and may increase this risk. Women with myomectomies have increased elective cesarean delivery rates and more blood loss at delivery compared with women with leiomyomas in situ.

Abstract
OBJECTIVE The authors conducted a large-scale cohort study using the Japan Society of Obstetrics and Gynecology's perinatal registry database to determine the effect of myomectomy on perinatal outcomes. METHODS This retrospective cohort study enrolled 203 745 women who gave birth between January and December 2020 in Japan. The participants were classified into two groups based on their history of myomectomy (open/laparoscopic) to investigate fertility treatment, delivery information, obstetric complications, maternal treatment, infant information, fetal appendages, obstetric history, underlying disease, infectious disease, drugs used, and case information regarding maternal and infant death. RESULTS In total, 1161 pregnant women had a history of myomectomy and 202 584 did not. Compared with the nonmyomectomy group, the myomectomy group had a higher occurrence rate of uterine rupture (0.9% vs 0.06%, P < 0.01) and placenta accreta (1.5% vs 0.5%, P < 0.01). In addition, history of myomectomy (odds ratio [OR], 2.62 [95% confidence interval (CI), 1.500-4.226]; P < 0.001) was found to be an independent factor for placenta accrete and uterine rupture (OR, 14.4 [95% CI, 6.75-27.02]; P < 0.001). Furthermore, myomectomy increased the risk of uterine rupture by 14 times. CONCLUSION Postmyomectomy pregnancy may increase the risk of placenta accreta and uterine rupture.

Abstract
Background and Objectives: Preterm birth (PTB) is associated with important neonatal mortality and morbidity. The aim of this study was to retrospectively evaluate the average treatment effects on the treated and the efficacity of various therapeutic interventions for PTB in a cohort of patients with singleton pregnancies and short cervical lengths. Materials and Methods: This observational retrospective study included 1146 singleton pregnancies at risk of PTB that were segregated into the following groups: intravaginal progesterone (group 1), Arabin pessary (group 2), McDonald cerclage (group 3), intravaginal progesterone and Arabin pessary (group 4), and intravaginal progesterone and cerclage (group 5). Their treatment effects were evaluated and compared. Results: All evaluated therapeutic interventions significantly reduced the occurrence of late and early preterm births. The risk of late and early PTB was lowered for those pregnant patients who received progesterone and pessaries or progesterone and cerclage in comparison with those who received only progesterone. The extremely PTB risk of occurrence was significantly lowered only by the administration of progesterone in association with cervical cerclage in comparison with progesterone monotherapy. Conclusions: The combined therapeutic interventions had the highest efficacy in preventing preterm birth. An individualized evaluation is needed to establish the best therapeutic approach in particular cases.

Abstract
OBJECTIVE Reproductive aged women with fibroids must weigh the risks and benefits of preconception myomectomy. Women with fibroids may have higher rates of fetal growth restriction (FGR) and stillbirth; however, there is a paucity of data on the impact of myomectomy on pregnancy outcomes. We compared perinatal outcomes in women with prior myomectomy versus those with no prior myomectomy and at least one fibroid ≥ 5 cm. METHODS Retrospective cohort study of women at a single center who delivered between 2008 and 2017 with a viable intrauterine pregnancy at initial ultrasound scan and either prior myomectomy, or, in the no-myomectomy cohort, at least one fibroid ≥ 5 cm on a prenatal scan performed at < 21 weeks' gestation (wga). Pregnancies complicated by major congenital anomalies were excluded. Primary outcome was preterm birth (PTB) < 37wga. Secondary outcomes included rates of spontaneous loss, cesarean delivery (CD), abnormal placentation, malpresentation, FGR, birthweight, birthweight percentile, estimated blood loss (EBL), blood transfusion, and neonatal survival to discharge. RESULTS A total of 290 women met inclusion criteria: 70 had a prior myomectomy, 220 women had ≥1 fibroid ≥5cm. Women with prior myomectomy were older, more likely to have private insurance, and more likely used artificial reproductive technology to conceive; 20% with prior myomectomy still had at least one ≥ 5 cm myoma on their obstetric scan. Rates of spontaneous loss were lower in the prior myomectomy group (1.4% vs 7.3%; p = .08). Of the 273 pregnancies continuing beyond 20 weeks, women with prior myomectomy had significantly more PTBs (35% vs. 21%, p = .02) and significantly different primary birth indications (p < .0001). However, after controlling for late preterm, prelabor cesareans recommended by providers in the myomectomy cohort, the difference in PTB rates was not significant (p = .13). The myomectomy group had more CDs (88% vs. 53%, p < .0001), higher EBL (1250 mL vs. 811 mL, p = .04), and a trend toward more blood transfusions (16% vs 8%, p = .05). Other selected outcomes were similar, including rates of FGR. CONCLUSIONS Women with prior myomectomy had significantly more PTBs, due in part to more preterm, prelabor cesareans in the late preterm period. Otherwise, prior myomectomy did not confer appreciable obstetric or perinatal benefits, as patients had more CDs, and higher EBL. Recommendations to perform preterm prelabor cesareans in this population may explain some of the PTB disparity. The effect of prior myomectomy on early pregnancy loss and infertility requires further study.
