RESUMEN

INTRODUCTION: Prenatal investigations are usually performed to diagnose severe or associated forms of hypospadias. However, the value of this workup and the correlation with the postnatal diagnosis and follow-up have not been studied in the literature. The aims of the study were to describe postnatal outcomes. MATERIAL AND METHODS: We conducted a single-center retrospective study. We included fetuses with a prenatal suspicion of isolated hypospadias (no associated ultrasound abnormality). Postnatal findings were described including neonatal examination with confirmation of the diagnosis or not of hypospadias, the diagnosis of isolated or associated hypospadias, investigations and management. RESULTS: A total of 21 patients with a suspicion of isolated hypospadias on prenatal ultrasound and available postnatal follow-up were included. The diagnosis of hypospadias was confirmed at neonatal examination for 17/21 (81 %) children. All 17 confirmed cases underwent at least one urological surgical procedure. Postnatally, the diagnosis of hypospadias in 4/17(23.5 %) cases was found to be associated with the following diagnosis: Denys-Drash syndrome, deletion of chromosome9 and duplication of chromosome20 involved in genital development, significant duplication of the short arm of chromosome 16, mosaic karyotypic abnormality [45, X (64 %)/46, XY (36 %)]. The hormonal assessment revealed 3/17(17.6 %) abnormalities: one diagnosis of partial androgen insensitivity syndrome and two cases of gonadal dysgenesis with low AMH and inhibin B. CONCLUSION: Prenatal diagnosis of isolated hypospadias may be associated with postnatal genetic abnormalities. In this context, a prenatal assessment by amniocentesis with chromosomal microarray analysis can be an option after discussion with the woman.

RESUMEN

Importance: The stereotype that men perform surgery better than women is ancient. Surgeons have long been mainly men, but in recent decades an inversion has begun; the number of women surgeons is increasing, especially in obstetrics and gynecology. Studies outside obstetrics suggest that postoperative morbidity and mortality may be lower after surgery by women. Objective: To evaluate the association between surgeons' gender and the risks of maternal morbidity and postpartum hemorrhage (PPH) after cesarean deliveries. Design, Setting, and Participants: This prospective cohort study was based on data from the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery (TRAAP2) trial, a multicenter, randomized, placebo-controlled trial that took place from March 2018 through January 2020 (23 months). It aimed to investigate whether the administration of tranexamic acid plus a prophylactic uterotonic agent decreased PPH incidence after cesarean delivery compared with a uterotonic agent alone. Women having a cesarean delivery before or during labor at or after 34 weeks' gestation were recruited from 27 French maternity hospitals. Exposures: Self-reported gender (man or woman), assessed by a questionnaire immediately after delivery. Main Outcomes and Measures: The primary end point was the incidence of a composite maternal morbidity variable, and the secondary end point was the incidence of PPH (the primary outcome of the TRAAP2 trial), defined by a calculated estimated blood loss exceeding 1000 mL or transfusion by day 2. Results: Among 4244 women included, men surgeons performed 943 cesarean deliveries (22.2%) and women surgeons performed 3301 (77.8%). The rate of attending obstetricians was higher among men (441 of 929 [47.5%]) than women (687 of 3239 [21.2%]). The risk of maternal morbidity did not differ for men and women surgeons: 119 of 837 (14.2%) vs 476 of 2928 (16.3%) (adjusted risk ratio, 0.92 [95% CI, 0.77-1.13]). Interaction between surgeon gender and level of experience on the risk of maternal morbidity was not statistically significant. Similarly, the groups did not differ for PPH risk (adjusted risk ratio, 0.98 [95% CI, 0.85-1.13]). Conclusions and Relevance: Risks of postoperative maternal morbidity and of PPH exceeding 1000 mL or requiring transfusion by day 2 did not differ by the surgeon's gender.

RESUMEN

BACKGROUND: Although prophylactic tranexamic acid administration after cesarean delivery resulted in a lower incidence of calculated estimated blood loss of >1000 mL or red cell transfusion by day 2, its failure to reduce the incidence of hemorrhage-related secondary clinical outcomes (TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery trial) makes its use questionable. The magnitude of its effect may differ in women at higher risk of blood loss, including those with multiple pregnancies. OBJECTIVE: This study aimed to compare the effect of tranexamic acid vs placebo to prevent blood loss after cesarean delivery among women with multiple pregnancies. STUDY DESIGN: This was a secondary analysis of the TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery trial data, a double-blind, randomized controlled trial from March 2018 to January 2020 in 27 French maternity hospitals, that included 319 women with multiple pregnancies. Women with a cesarean delivery before or during labor at ≥34 weeks of gestation were randomized to receive intravenously 1 g of tranexamic acid (n=160) or placebo (n=159), both with prophylactic uterotonics. The primary outcome was a calculated estimated blood loss of >1000 mL or a red blood cell transfusion by 2 days after delivery. The secondary outcomes included clinical and laboratory blood loss measurements. RESULTS: Of the 4551 women randomized in this trial, 319 had a multiple pregnancy and cesarean delivery, and 298 (93.4%) had primary outcome data available. This outcome occurred in 62 of 147 women (42.2%) in the tranexamic acid group and 67 of 152 (44.1%) receiving placebo (adjusted risk ratio, 0.97; 95% confidence interval, 0.68-1.38; P=.86). No significant between-group differences occurred for any hemorrhage-related clinical outcomes: gravimetrically estimated blood loss, provider-assessed clinically significant hemorrhage, additional uterotonics, postpartum blood transfusion, arterial embolization, and emergency surgery (P>.05 for all comparisons). CONCLUSION: Among women with a multiple pregnancy and cesarean delivery, prophylactic tranexamic acid did not reduce the incidence of any blood loss-related outcomes.

RESUMEN

BACKGROUND: The number of twin pregnancies continues to increase worldwide as both the number of pregnancies obtained by medically assisted reproduction and age at first pregnancy keep rising. Preterm delivery is the major complication associated with twin pregnancies. The effectiveness of preventive treatments such as progesterone or cervical cerclage for women with a short cervix is doubtful in twin pregnancies. The effectivity of cervical pessaries in preventing preterm birth and its associated morbidity and mortality is also controversial. OBJECTIVE: We sought to investigate if the Arabin pessary reduces adverse neonatal outcomes in twin pregnancies with a short cervix. STUDY DESIGN: This open-label, multicenter, randomized controlled trial on twin pregnancies with a cervical length of <35 mm compared pessary placement at 16+0 to 24+0 weeks' gestation with standard care alone. The primary endpoint was a composite of adverse neonatal outcomes, namely peripartum or neonatal death or significant neonatal morbidity before hospital discharge, defined as at least 1 of the following complications: bronchopulmonary dysplasia, intraventricular hemorrhage grade III to IV, periventricular leukomalacia, necrotizing enterocolitis grade II or higher, culture-proven sepsis, and retinopathy requiring treatment. A sample size of 308 pregnancies was planned to ensure 80% power to compare the proportions of women with at least 1 infant with an adverse neonatal outcome. The intention-to-treat analysis after multiple imputation of missing data, was supplemented with a secondary analysis that controlled for gestational age and cervical length, both at inclusion. The primary endpoint was also compared between randomization groups in the per-protocol population, which excluded patients with prespecified major protocol violations (mostly cervical cerclage and/or progesterone after inclusion). Secondary endpoints included preterm birth, spontaneous preterm birth, and pessary side effects. RESULTS: In total, 315 women were randomized to either receive a pessary (n=157) or standard management (n=158). Overall, 10.8% (34 women) of participants had a missing value for the primary endpoint, mostly (79%) because of the lack of paternal consent for neonatal data collection. In the intention-to-treat analysis, the adverse neonatal outcome occurred in 16.8% of the pessary group vs in 22.5% of the control group (risk ratio, 0.69; 95% confidence interval, 0.39-1.23; P=.210). The per-protocol analysis did not show any significant difference between groups (risk ratio, 0.78; 95% confidence interval, 0.47-1.28; P=.320). The occurrence of preterm birth or spontaneous preterm birth did not differ significantly between groups. No serious side effects were associated with pessary use. CONCLUSION: Pessary use in our study did not significantly reduce adverse neonatal outcomes in twin pregnancies with a short cervix.

RESUMEN

Postpartum hemorrhage remains one of the principal causes of maternal mortality in the United States and throughout the world. Its management, which must be multidisciplinary (obstetrics, midwifery, anesthesiology, interventional radiology, and nursing), depends on the speed of both diagnosis and implementation of medical and surgical treatment to control the hemorrhage. The aim of this work is to describe the various techniques of vessel ligation and of uterine compression for controlling and treating severe hemorrhage, and to present the advantages and disadvantages of each. It is not difficult to perform vessel ligation of the uterine arteries: O'Leary's bilateral ligation of the uterine artery, Tsirulnikov's triple ligation, and AbdRabbo's stepwise uterine devascularization (that is, stepwise triple ligation). These procedures are associated with a high success rate (approximately 90%) and a low complication rate. Bilateral ligation of the internal iliac (hypogastric) arteries is more difficult to perform and potentially less effective (approximately 70% effectiveness) than the previously mentioned procedures. Its complication rate is low, but the complications are most often serious. There is no evidence that future fertility or subsequent obstetrical outcomes are impaired by ligation of either the uterine or internal iliac arteries. There are many techniques used for uterine compression sutures, and none has shown clear superiority to another. Uterine compression suture has an effectiveness rate of approximately 75% after failure of medical treatment and approximately 80% as a second-line procedure after unsuccessful vessel ligation. The risk of synechiae after uterine compression suture has not yet been adequately evaluated, but is probably around 5%. The risk of synechiae after uterine compression suture has not yet been adequately evaluated, but probably ranges between 5% and 10%. The methodologic quality of the studies assessing uterine-sparing surgical procedures remains limited, with no comparative studies. Accordingly, no evidence suggests that any one of these methods is better than any other. Accordingly, the choice of surgical technique to control hemorrhage must be guided firstly by the operator's experience. If the hemorrhage continues after a first-line uterine-sparing surgical procedure and the patient remains hemodynamically stable, a second-line procedure can be chosen. Nonetheless, the application of these procedures must not delay the performance of a peripartum hysterectomy in cases of hemodynamic instability.

RESUMEN

INTRODUCTION: In Doppler flow diagnosis of a large placental chorioangioma with vascularization, there may be fetal consequences as cardiac output failure and polyhydramnios. Prenatal percutaneous fetoscopic laser photocoagulation of chorioangioma is a therapeutic option. First, we present 2 cases of chorioangioma treated by fetoscopic laser photocoagulation. Second, we conducted a narrative review to identify all reported cases of chorioangioma treated by fetoscopic laser photocoagulation. CASE PRESENTATION: Case 1 presented a chorioangioma measuring 48 × 36 × 42 mm, and the Doppler flow study showed vascularization with a high flow rate. The fetus showed dilatation of the right cardiac chambers, moderate tricuspid insufficiency, normal Doppler indices, and polyhydramnios. Case 2 presented a chorioangioma measuring 58 × 36 × 31 mm associated with polyhydramnios and elevated peak systolic velocity of the middle cerebral artery at 49 cm/s, that is, 1.65 MoM. The procedure was performed at 22+2 and 23+5 WG for both cases. Photocoagulation of the chorioangioma vessels was performed first on the small superficial vessels (capillaries) and then on the feeding vessels (artery first and then vein), until complete cessation of blood flow on ultrasound. Successful devascularization was achieved when flow within the chorioangioma's feeding vessels was no longer visualized on intraoperative ultrasound examination using Doppler flow. The ultrasound follow-up showed complete cessation of blood flow in the chorioangioma, normalization of fetal signs, and normal fetal growth in both cases. In case 1, a 2,350-g boy was delivered vaginally after spontaneous labor at 33+6 WG. In case 2, a 2,700-g boy was delivered vaginally after spontaneous labor at 39+2 WG. Neonatal findings were normal, and the outcome at 1 year was normal for both children. CONCLUSION: Prenatal percutaneous fetoscopic laser photocoagulation improves survival in large chorioangioma, despite a risk of fetal death in utero.

RESUMEN

First trimester ultrasound screening is an essential fetal examination performed generally at 11-13 weeks of gestation (WG). However, it does not allow for an accurate description of all fetal organs, partly due to their development in progress. Meanwhile, increased nuchal translucency (INT) is a widely used marker known to be associated with chromosomal deleterious rearrangements. We report on a 14 WG fetus with an association of INT and univentricular congenital heart malformation (CHM) leading to chorionic villous sampling (CVS). Cytogenetic investigations performed using array-Comparative Genomic Hybridization (CGH) and fluorescence in situ hybridization (FISH) demonstrated a 1.17 Mb deletion in 16q24.1 encompassing FOXF1 arisen de novo on maternal inherited chromosome. Fetopathological study confirmed CHM with hypoplastic left heart syndrome (HLHS) associating aortic atresia, mitral stenosis, and left ventricular hypoplasia and revealed in addition specific lung lesions corresponding to alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV). This is so far the first case of first trimester prenatal diagnosis of ACDMPV due to the deletion of FOXF1 gene. An interpretation of the complex genomic data generated by ultrasound markers is facilitated considerably by the genotype-phenotype correlations on fetopathological examination.

RESUMEN

OBJECTIVE: The objective of this study is to assess the effectiveness and safety of intrafetal vascular laser ablation (VLA) for fetuses with bronchopulmonary sequestration (BPS) with hydrops. METHODS: First, we present 3 cases of fetuses with BPS and hydrops treated by VLA. Second, we aimed to conduct a narrative review to identify all reported cases of fetuses with BPS treated by intrafetal VLA. RESULTS: The review of the literature identified 41 fetuses treated by VLA for BPS with hydrops. The median gestational age of the VLA was 27+0 weeks' gestation [25+0-31+0] with an associated procedure at the same time in 43% of the cases (pleuroamniotic shunt, thoracentesis, and amniodrainage). A second procedure was required in 25% of cases for residual flow in the feeding vessel. No stillbirth or neonatal death was reported. The complications reported were a fetal thoracic hematoma complicated by fetal anemia and 4 preterm deliveries with a rate of 9%. CONCLUSION: VLA of the feeding vessel can be an effective treatment but is not without complications. In cases demonstrating cardiac output failure, intrafetal VLA should be considered as a treatment for BPS.

RESUMEN

Monochorionic pregnancies are associated with a higher risk of perinatal morbidity and mortality than dichorionic pregnancies. Early determination of chorionicity by an ultrasound exam between 11+0 and 14+0 weeks' gestation (WG) is essential for the subsequent management of twin pregnancies. The presence of the T-sign is the most specific sign for determination of monochorionicity. During the second trimester, the presence of two distinct placental masses has a lower specificity in determining the chorionicity. We report here two cases of a monochorionic pregnancy with a bipartite placenta, suggesting that a placenta with two separate masses, each with a distinct cord insertion is not always indicative of a dichorionic pregnancy.'

RESUMEN

OBJECTIVE: To evaluate neonatal mortality and morbidity up to 6 months in neonates with congenital diaphragmatic hernia (CDH) with or without a hernia sac. METHODS: Seventy-two cases of isolated CDH were included in a retrospective single-center study between January 2010 and December 2016. Hernia sac was defined at the time of surgery or at postmortem examination if the neonate died before surgery. RESULTS: Seventeen newborns (23.6%) had a hernia sac. Survival at 6 months was significantly greater for isolated CDH with a hernia sac: 100% versus 63.6% (P = .003). High-frequency oscillatory ventilation was used significantly more in the no hernia sac group (P = .04). At surgery, the need for patch repair was significantly lower in the hernia sac group: 12% versus 50% (P = .005). The prenatal observed/expected lung-to-head ratio was significantly higher in the hernia sac group than in the no hernia sac group: 49.7% versus 38.6% (P < .05). CONCLUSION: The presence of a hernia sac in CDH is associated with better outcome, especially survival at 6 months. If the presence of a hernia sac is recognized as a particular entity, which carries a good prognosis, it is necessary to be able to diagnose it prenatally, especially in the era of prenatal fetal surgery.

RESUMEN

OBJECTIVE: The objective of the investigation was to study the relationship between gestational age at diagnosis and mortality and morbidity in fetuses with an isolated congenital diaphragmatic hernia. STUDY DESIGN: Between January 2008 and November 2013, 377 live births with isolated congenital diaphragmatic hernia diagnosed antenatally at a known gestational age were recorded in the database of the French National Center for Rare Diseases. The primary outcome studied was mortality estimated at 28 days and at 6 months. The secondary outcome was morbidity evaluated by pulmonary arterial hypertension at 48 hours, oxygen therapy dependence at 28 days, oral disorders, enteral feeding, and prosthetic patch repair. Analyses were adjusted for the main factors of congenital diaphragmatic hernia severity (side of the hernia, thoracic herniation of the liver, gestational age at birth, lung-to-head ratio, and prenatal treatment by tracheal occlusion. RESULTS: Mortality rates at 28 days decreased significantly (P < .001) when gestational age at diagnosis increased: 61.1%, 39.2%, and 10.4% for a diagnosis in the first, second, and third trimester, respectively. Adjusted odds ratios were 3.12 [95% confidence interval, 1.86-5.25] and 0.35 [95% confidence interval, 0.18-0.66] for a diagnosis in the first and third trimesters, respectively, compared with a diagnosis in the second trimester. Similarly, morbidity decreased significantly when gestational age at diagnosis increased, and the trend remained significant after adjustment for the main factors of congenital diaphragmatic hernia severity (P < .001). CONCLUSION: Gestational age at diagnosis is an independent predictor of postnatal prognosis for children presenting an isolated congenital diaphragmatic hernia and should be taken into account when estimating postnatal morbidity and mortality.
