RESUMO
OBJECTIVES: Evaluate the prevalence of uterine synechia after total uterine ligation (TUL) in comparison to TUL associated with compression-penetrating-sutures (CPS) in the conservative surgical management of severe postpartum hemorrhage (PPH). METHODS: Prospective observational study of pregnant women that underwent conservative surgical management for PPH in a single French tertiary referral center. We compared the risk of uterine synechia with TUL, in comparison to performing TUL in addition to CPS. The synechia rate was calculated after uterine cavity assessment by 3D hysterosonography. Hysterectomies, women with placenta accreta spectrum and patients that received additional embolization treatment were excluded. RESULTS: Over 6 years, 36 pregnant women underwent surgical treatment for PPH in 21,944 deliveries (1.64 per 1000). The median blood loss was 2700 [1570-3000] milliliters. Twenty-eight (77.7%) women underwent TUL, 8/36 (22.2%) underwent TUL in addition to CPS. Thirty-four (94,4%) cavity assessments were performed 2-to-6 months after delivery, since one woman of each group was lost to follow-up. When TUL was performed in addition to CPS, the prevalence of synechia was 42.9% (n = 3/7), versus 3.7% (n = 1/27) in TUL (p = 0.021; RR = 16.88, 95%CI [1.1-1051]). Synechia was absent in 30/34 (88.2%) women. CONCLUSION: The prevalence of synechia was very low after TUL unlike CPS. Further studies should evaluate TUL in the conservative surgical management of PPH, to confirm the lower prevalence of synechiae in TUL and evaluate its impact on fertility.

OBJECTIVE: To describe and compare the characteristics of women with placenta accreta spectrum (PAS) and their pregnancy outcomes according to the presence of placenta praevia and a prior caesarean section. DESIGN: Prospective population-based study. SETTING: All 176 maternity hospitals of eight French regions. POPULATION: Two hundred and forty-nine women with PAS, from a source population of 520 114 deliveries. METHODS: Women with PAS were classified into two risk-profile groups, with or without the high-risk combination of placenta praevia (or an anterior low-lying placenta) and at least one prior caesarean. These two groups were described and compared. MAIN OUTCOME MEASURES: Population-based incidence of PAS, characteristics of women, pregnancies, deliveries and pregnancy outcomes. RESULTS: The PAS population-based incidence was 4.8/10 000 (95% CI 4.2-5.4/10 000). After exclusion of women lost to follow up from the analysis, the group with placenta praevia and a prior caesarean included 115 (48%) women and the group without this combination included 127 (52%). In the group with both factors, PAS was more often suspected antenatally (77% versus 17%; P < 0.001) and more often percreta (38% versus 5%; P < 0.001). This group also had more hysterectomies (53% versus 21%, P < 0.001) and higher rates of blood product transfusions, maternal complications, preterm births and neonatal intensive care unit admissions. Sensitivity analysis showed similar results after exclusion of women who delivered vaginally. CONCLUSION: More than half the cases of PAS occurred in women without the combination of placenta praevia and a prior caesarean delivery, and these women had better maternal and neonatal outcomes. We cannot completely rule out that some of the women who delivered vaginally had placental retention rather than PAS; however, we found similar results among women who delivered by caesarean. TWEETABLE ABSTRACT: Half the women with PAS do not have both placenta praevia and a prior caesarean delivery, and they have better maternal outcomes.

OBJECTIVE: The aim of the study was to assess the chronology of the appearance of perpartum obstetric risk factors (POR) in order to define the best moment to evaluate the type of management to which women will be oriented. We have secondarily studied the extent to which inappropriate medical interventions play a role in the genesis of some complications in the deliveries of women who are in principle at low risk. MATERIALS AND METHODS: We conducted a prospective cohort study from January 1 to June 30, 2015 at the Croix-Rousse Hospital of Lyon, a level III maternity, and the Valence Hospital Center, a level II maternity, including all women giving birth at 24 to 42 weeks of gestation at hospital. The women were divided into two groups : one with no known perpartum obstetric risk (POR-) and the other with at least one obstetrical perpartum risk factor (POR+), defined at three different stages (at the last pregnancy monitoring consultation, at the onset of labor at the admission in the delivery room, and at the end of labor just before expulsive efforts). We observed medical interventions and foeto-maternal complications in each group. A non-simple delivery was a delivery involving a medical intervention, or a maternal or neonatal complication, or any combination of these. A secondary retrospective analysis of the practices and management was made for women initially considered POR- at the onset of labor but who had a non-simple delivery to assess adherence to current guidelines according to an audit schedule. RESULTS: Among 1975 women, we identified 32% women as POR- at end of pregnancy, 21% at start of labor and 20% at end of labor. Among the POR- women at start of labor, 16% had a non-simple delivery. 35% of these non-simple deliveries might perhaps have been avoided by closer adherence to current recommendations. Nonetheless 54% of these women still had an unpredictable and inevitable non-simple delivery that in some cases required an extremely rapid intervention. CONCLUSION: Determining and predicting pregnant women who will need additional resources in addition to the usual obstetric and neonatal care is difficult. This identification should be made at the admission for delivery and this risk should be reassessed during labor. There are no women at zero risk of intervention. Therefore, delivery in demedicalized units should not take place in isolated or distant free-standing facilities.

OBJECTIVES: To evaluate an in situ training program on caradiotocography interpretation during labor in the Auvergne-Rhône-Alpes region (France). METHODS: Fifteen hospital maternity unit took part to an "outreach visit" training on fetal cardiotocography interpretation between November 2011 and 2015. Professionals were asked to answer to a 10 questions test based on the French classification of fetal heart rate, at inclusion (Test 0: T0), immediately after (Test 1: T1), and long time after the training (Test 2: T2). The mean score for each maternity (T0, T1, T2) was compared individually. Subgroup analysis considered the level of perinatal care of each maternity (level 1 or 2) and the type of practice (public or private). RESULTS: The study included 332 healthcare professionals belonging to 8 level 1 (53.5%) and 7 level 2 (47.7%) maternity units. The T0 mean score was 4.79 (IC 95% [4.54; 5.02]) instead of 6.71(IC 95% [6.49; 6.93]) at T1 (P<0.05). Seventeen professionals (22.9%) answered T2 with a mean time of 35.2 months (Median value: 40 months) and a mean score of 5.32. The mean score was significantly higher at T2 than at T0 (5.32-IC 95%[4.94-5.70] (P<0.001) but lower than the score at T1 (P<0.05). CONCLUSION: An "outreach visit" training on fetal cardiotocography interpretation improves theknowledge of healthcare professionals at short and long term.

INTRODUCTION: To assess the obstetric outcome of pregnancies occurring after a complete uterine rupture. METHODS: Descriptive study of a series of 11 pregnancies after complete uterine rupture. RESULTS: This study includes 10 women with 11 pregnancies. There were no recurrences of complete uterine rupture. All women had cesarean deliveries between 32 and 37 weeks' gestation. There were no cases of either severe hemorrhage or placenta accreta and no maternal or neonatal deaths. All women had close clinical and ultrasound monitoring and were hospitalized during the third trimester. CONCLUSION: Women with a history of complete uterine rupture can have a subsequent pregnancy with a thoroughly favorable outcome with appropriate care conditions, including prophylactic caesarean section.

OBJECTIVES: This study aims to describe how microarray comparative genomic hybridization (aCGH) has shifted to become a prenatal diagnosis tool at the Lyon university-hospital. MATERIALS AND METHODS: This retrospective study included all patients who were referred in the 3 pluridisciplinary centers for prenatal diagnosis of the Lyon university-hospital and who received a prenatal aCGH between June 2013 and June 2015. aCGH was systematically performed in parallel with a karyotype, using the PréCytoNEM array design. RESULTS: A total of 260 microarrays were performed for the following indications: 249 abnormal ultrasounds (95.8%), 7 characterizations of chromosomal rearrangements (2.7%), and 4 twins with no abnormal ultrasounds (1.5%). With a resolution of 1 mega base, we found 235 normal results (90.4%), 23 abnormal results (8.8%) and 2 non-returns (0.8%). For the chromosomal rearrangements visible on the karyotype, aCGH identified all of the 12 unbalanced rearrangements and did not identify the 2 balanced rearrangements. Among the fetuses with normal karyotypes, 11 showed abnormal microarray results, corresponding to unbalanced cryptic chromosomal rearrangements (4.2%). CONCLUSION: Transferring aCGH to a prenatal diagnosis at the Lyon university-hospital has increased the detection rate of chromosomal abnormalities by 4.2% compared to the single karyotype.

Essentials Pregnancy is a risk factor for thrombosis. Management of thrombosis risk in pregnancy remains a challenge. Prophylaxis needs to be personalized. Our score may be a helpful tool for the management of pregnancies at high risk of thrombosis. SUMMARY: Background Patients with thrombophilia and/or a history of venous thromboembolism (VTE) are at risk of thrombosis during pregnancy. A risk score for pregnancies with an increased risk of VTE was previously described by our group (Lyon VTE score). Objectives The aim of this prospective study was to assess the efficacy and safety of our score-based prophylaxis strategy in 542 pregnancies managed between 2005 and 2015 in Lyon University Hospitals. Patients/Methods Of 445 patients included in the study, 36 had several pregnancies during the study period. Among these 445 patients, 279 had a personal history of VTE (62.7%), 299 patients (67.2%) had a thrombophilia marker, and 131 (29.4%) thrombophilic women had a personal history of VTE. During pregnancy, patients were assigned to one of three prophylaxis strategies according to the risk scoring system. Results In the antepartum period, low molecular weight heparin (LMWH) prophylaxis was prescribed to 64.5% of patients at high risk of VTE. Among them, 34.4% were treated in the third trimester only, and 30.1% were treated throughout pregnancy. During the postpartum period, all patients received LMWH for at least 6 weeks. Two antepartum-related VTEs (0.37%; one with a score of < 3 and the other with a score of > 6) and four postpartum-related VTEs (0.73%; three with scores of 3-5 and one with a score of > 6) occurred. No case of pulmonary embolism was observed during the study period. The rate of bleeding was 0.37%. No serious bleeding requiring transfusions or surgery occurred during the study period. Conclusion The use of a risk score may provide a rational decision process to implement safe and effective antepartum thromboprophylaxis in pregnant women at high risk of VTE.

OBJECTIVE: To demonstrate the feasibility and efficacy of high-intensity focused ultrasound (HIFU) for the non-invasive creation of placental lesions in a simian model. METHODS: Eight pregnant monkeys were exposed to HIFU treatment after anesthesia, using a toroidal HIFU 2.5-MHz transducer with an integrated ultrasound imaging probe. Lesions on the placental tissue were created non-invasively by placing the HIFU probe on the skin surface. Fetal and maternal parameters, such as maternal heart rate, fetal heart rate and subcutaneous and intra-amniotic fluid temperature, were recorded during HIFU exposure. Cesarean section was performed immediately after the procedure to extract the placenta and examine the fetus and the maternal abdominal cavity. Placental HIFU lesions were assessed by ultrasound, gross pathology and histology. RESULTS: The mean gestational age of the monkeys was 72 ± 4 days. In total, 13 HIFU procedures were performed. The acoustic power and exposure time were increased progressively. This gradual increase in total energy delivered was used to determine a set of parameters to create reproducible lesions in the placenta without complications. Five placental lesions were observed with average diameters of 6.4 ± 0.5 mm and 7.8 ± 0.7 mm and an average depth of 3.8 ± 1.5 mm. Ultrasound examination of the placentae revealed hyperechoic regions that correlated well with macroscopic analysis of the HIFU lesions. Necrosis of placental tissue exposed to HIFU was confirmed with macroscopic and microscopic analysis. There was no significant variation in maternal and fetal parameters during HIFU exposure. CONCLUSIONS: This study demonstrates the feasibility of HIFU applied non-invasively to the placental unit in an in-vivo pregnant monkey model. The technique is safe in the immediate short term and is potentially translatable to human pregnancy. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Pregnancy in a rudimentary horn of a pseudo-horned uterus is a rare obstetrical situation, for which, maternal-fetal prognosis is altered by the risk of uterine rupture. We report a rare case of pregnancy in a rudimentary horn with birth of a living child at 28 weeks of amenorrhea. During caesarean, uterine rupture plugged by the omentum was observed. We discuss from this case obstetric management of this pathology.

OBJECTIVES: Placental growth factor (PlGF) is a pro-angiogenic factor mainly assessed in preeclampsia in which its blood concentration is decreased. The aim of this study was to dose the blood concentration of PlGF in women with fetal intra-uterine growth restriction (IUGR) without associated preeclampsia at the time of diagnosis. METHODS: Case/control study: IUGR was defined by a fetal biometry with abnormal uterine and/or umbilical doppler (n=23). This group was compared to a control group of fetuses (n=25) matched for gestational age at blood sampling for the dosage of maternal seric PlGF. Women with preeclampsia were not included. RESULTS: The plasma PlGF concentration was 11pg/mL (IQR [11-42,8]) in the IUGR group vs 287pg/mL [135-439] in the control group (P<0.001) and this difference was available after adjustment for gestational age at the time of blood sampling (P<0.001). PlGF sensitivity and specificity for discrimination were respectively 87% (CI 95% [66-97]) and 88% (CI 95% [69-97]). CONCLUSION: Maternal serum PlGF concentrations were very low in IUGR group compared with those of the control group.

INTRODUCTION: Bladder augmentation is commonly used in neurological and other congenital anomalies of the lower urinary tract. In pregnant women, this reconstructive surgery may affect pregnancy and delivery. The obstetrical consequences of these urological procedures are scarcely reported in literature. MATERIAL AND METHOD: Eight pregnancies in 6 pregnant women with ileocystoplasty were followed in our institution between 1998 and 2014. RESULTS: Urinary tract infections were the most frequent undesirable record event (5 patients, 7 pregnancies). Obstetrical complications were not more frequent compared to common pregnancies. Delivery was programmed at 37WA. Cesarean section was favoured in this group although natural delivery is possible. CONCLUSION: Urological complications were the major problem in this series. The type of delivery depends on the past surgical history and the obstetrical prognosis.

OBJECTIVES: To describe the distribution of the volume of blood loss during vaginal and cesarean deliveries among women who delivered after 24 weeks of gestation. MATERIALS AND METHODS: A descriptive study of the distribution of blood loss by delivery route and for all patients after 24 weeks of gestation over a period of two years in a type III maternity. Patient and delivery characteristics were collected and blood loss was measured prospectively based on weighing pads and the use of a collector bag for vaginal deliveries, a suction cannula for cesareans sections. The following parameters were calculated: the mean (±SD), the median, interquartile range (IQR), the 5th and 95th percentile. RESULTS: Seven thousand nine hundreds and eight patients were included. After vaginal delivery (n=6134), the mean volume of bleeding was equal to 180.1 mL (± 224.7 mL), the median to 100mL (IQR [100-200]), the 95th percentile to 500 mL [CI 95% 500-550]. For cesarean sections (n=1774), the mean volume of bleeding was equal to 557.9mL (± 496.2 mL), the median volume of blood loss to 400 mL (IQR [300-700]), the 95th percentile to 1300 mL [CI 95% 1200-1500]. CONCLUSION: The distribution of blood loss after cesarean was significantly higher than the distribution of blood loss after vaginal delivery.

OBJECTIVE: To describe the characteristics, management, and outcomes of women undergoing invasive therapies for primary postpartum haemorrhage (PPH). DESIGN: A population-based observational study. SETTING: All 106 maternity units of six French regions. POPULATION: A total of 146 781 women delivering between 2004 and 2006. METHODS: Prospective identification of women with PPH managed with invasive therapies, including uterine suture, pelvic vessel ligation, arterial embolisation, and hysterectomy. MAIN OUTCOME MEASURES: Rate of use and failure rate of invasive therapies, with 95% confidence intervals (95% CIs). RESULTS: An invasive therapy was used in 296 of 6660 women with PPH (4.4%, 95% CI 4.0-5.0), and in 0.2% of deliveries (95% CI 0.18-0.23). A hysterectomy was performed in 72/6660 women with PPH (1.1%, 95% CI 0.8-1.4%), and in 0.05% of deliveries (95% CI 0.04-0.06). A conservative invasive therapy was used in 262 women, including 183 (70%) who underwent arterial embolisation and 79 (30%) who had conservative surgery as the first-line therapy. Embolisation was more frequently used after vaginal than caesarean delivery, and when arterial embolisation was available on site. The failure rate of conservative invasive therapies was 41/262 (15.6%, 95% CI 11.5-20.6) overall, and was higher after surgical than after embolisation procedures, in particular for vaginal deliveries. CONCLUSIONS: Both maternal mortality as a result of obstetric haemorrhage and the rate of invasive therapies used for PPH are high in France. These findings suggest flaws in the initial management of PPH and/or the inadequate use of invasive procedures. TWEETABLE ABSTRACT: Maternal mortality as a result of haemorrhage and the rate of invasive therapies used for PPH are high in France.

OBJECTIVES: To estimate the frequency of accidental out-of-hospital deliveries (OHDs), to describe the home care and the complications occurred, and to identify risk factors. MATERIALS AND METHODS: A retrospective case-control study from 1st January 2012 to 31 December 2012 in Lyon urban area. Cases were identified from the Emergency Medical Aid Service 69 (SAMU 69) registry and control from the birth registry of the maternity corresponding to the case, recruiting two controls per case. RESULTS: The frequency of the OHDs was 0.3% [0.2-0.4]. At home, the prophylactic administration of oxytocin was performed in 18.3% [9.31-27.3] of cases and prevention of neonatal hypothermia was performed in 45.7% [34.1%-57.3%] of cases. Multiparity [OR: 3.43 (1.65-7.23)], a precarious situation [OR: 37.63 (5.02-7.81)], and lack of antenatal care [OR: 3.36 (2.72-4.15)] were OHDs' risk factors. CONCLUSION: The practical prevention of postpartum hemorrhage, and that of the home neonatal hypothermia could be improved. Points of vigilance for the medical teams to look for during the pregnancy monitoring are precariousness and less than 3 consultations scheduled.

OBJECTIVE: More and more women with spinal cord injury (SCI) can have a pregnancy. Few data have been published on these pregnancies and their urological impact. We report a series of these cases illustrating the urological experience of specialized centers. METHODS: This is a retrospective study that identified pregnancies in women with SCI followed-up between 2000 and 2014. Data covering all urological and obstetric events during pregnancies, before and after implementation of weekly oral cyclic antibiotics (WOCA) program, were collected from medical records. RESULTS: Fifteen women with SCI who gave birth to 20 children were included. Three of them were quadriplegics and 12 were paraplegics. All of them performed themselves intermittent catheterization: 11 by urethral way and 4 by high way because carrying a continent cystostomy. Mean follow-up period before pregnancy was 14.6 years [3-27 years IC 95%] and the mean follow-up for the study was 8.5 months [6.5-9 IC 95%]. We observed a reduction of symptomatic urinary tract infections after WOCA onset (13/13 before vs. 0/7 after, P=0.001), a reduction of recurrent urinary infections (6/13 vs. 0/7, P=0.03), a reduction of threats to premature births (8/13 vs. 0/7, P=0.001). Multi-resistant bacteria appeared to increase (0/13 vs. 3/7, P=0.01). We also observed a trend to significant reduction of premature births number (4/13 vs. 0/13, P=0.1) and that of low birth weight (3/13 versus 0/7, P=0.1). The overall neonatal survival rate was 100%. CONCLUSION: Our study before/after introduction of a weekly oral cycle antibiotic prophylaxis during pregnancy for women with spinal cord injury showed a significant reduction in symptomatic urinary tract infections and a tendency to improve pregnancy outcomes. LEVEL OF EVIDENCE: 4.

OBJECTIVE: To demonstrate in an ex-vivo model the feasibility of applying high-intensity focused ultrasound (HIFU) using a toroidal transducer for the creation of placental lesions. METHODS: In this study we used a toroidal transducer, composed of 32 ring-shaped emitters with an ultrasound probe at the center, operating at a frequency of 2.5 MHz. We examined 45 human placentae, following either normal vaginal delivery or medical termination of pregnancy between 17 and 40 gestational weeks. First, the attenuation coefficients of 12 human placentae were measured and integrated into a numerical model for simulating HIFU lesions. Then, using acoustic parameters from this preliminary study, we performed ex-vivo experiments with 33 human placentae, each overlain with an animal abdominal wall to simulate the maternal wall. We created single HIFU lesions in 25 of these placentae, and a series of six juxtaposed lesions in eight, studying these both sonographically and macroscopically. RESULTS: Human placental attenuation coefficients of the 12 human placentae ranged from 0.072 to 0.098 Np/cm/MHz, according to gestational age. The 25 single HIFU lesions created had an average diameter of 7.1 ± 3.2 mm and an average depth of 8.2 ± 3.1 mm. The average diameter of the eight series of six juxtaposed HIFU lesions was 23.0 ± 5.0 mm and the average depth was 11.0 ± 4.7 mm. The average thickness of the abdominal walls was 10.5 ± 1.8 mm. No lesions or damage were observed in intervening tissues. CONCLUSION: This study demonstrates, using an ex-vivo model, the feasibility, reproducibility, harmlessness and effectiveness of HIFU applied to the human placenta.

OBJECTIVES: Evaluate the incidence of perinatal mortality and evaluate the percentage of non optimal care management of fatal pregnancies between 2005 and 2011 in the Rhone-Alpes region in France, by the use of the Aurore network. Evaluate the development of morbi-mortality revues (MMR) in this region. METHODS: Retrospective study of perinatal mortality in the Aurore network, from 2005 to 2011. Systematic analysis of care management (adapted, non adapted, non evaluable), of each perinatal death that occurred in the Aurore network, by a multidisciplinary committee during regional MMR. RESULTS: The incidence of perinatal mortality has diminished from 2005 to 2011 (8,4 vs. 6,4, P<0.07) as well as the percentage of non adapted care management (13% vs. 5,6%, P<0.001). An underestimation of irregularities in the fetal heart rate was described in 34% of per partum deaths. The percentage of optimal care management was significantly higher when the obstetrician was in the maternity rather than on call at home (P<0.03) and in type 3 maternities compared to type 1 and 2 maternities (P<0.04). The attendance of the MMR organized in the AURORE network progressed between 2006 and 2011. CONCLUSION: Since 2005, a decrease in perinatal mortality and in non-adapted care management was observed. More studies are necessary to evaluate the link between the development of MMR in this network and the amelioration of these two indicators.

OBJECTIVE: Echogenic bowel (EB) represents 1 % of pregnancy and is a risk factor of fetal pathology (infection, cystic fibrosis, aneuploidy). The aim of our study was to determine the fetuses' outcomes with isolated EB. PATIENTS AND METHODS: This is a retrospective study of all patients who presented singleton gestations with a fetal isolated echogenic bowel between 2004 and 2011 in two prenatal diagnosis centers. Search of aneuploidy, infection and cystic fibrosis was systematically proposed as well as an ultrasound monitoring. RESULTS: On 109 fetus addressed for isolate echogenic bowel five had other signs associated and 74 had a real isolated echogenic bowel (without dilatation, calcification, intrauterine growth restriction). In 30 cases, the EB was not found. Eighty-five percent of the patients had in the first trimester a screening for trisomy 21. None fetus with isolated EB had trisomy, infection or cystic fibrosis. One fetus died in utero and one newborn died of a metabolic disease without digestive repercussions. DISCUSSION AND CONCLUSION: The risk of trisomy 21 and the risk to have a serious disease appear low for the fetus with EB. It does not seem necessary to propose a systematic amniocentesis in case of isolated echogenic bowel.

OBJECTIVE: To estimate the incidence, to describe the aetiology and to identify the risk factors of postpartum haemorrhage (PPH). MATERIAL AND METHOD: Prospective study conducted in 106 French maternity units of six perinatal networks between December 2004 and November 2006. PPH was defined by a blood loss superior to 500 mL or necessitating an examination of the uterus, or a peripartum haemoglobin drop superior to 2 g/dL. Severe PPH was defined by at least one of these criteria : peripartum haemoglobin drop superior or equal to 4 g/dL, embolization, conservative surgical procedure, hysterectomy, transfusion, transfer to intensive care or death. RESULTS: The incidence of PPH was 6.4% [CI 95% 6.3-6.5] with variations between maternity units from 1.5% to 22.0%; incidence of severe PPH was 1.7% [CI 95% 1.6-1.8] with variations between units from 0% to 4%. Atony was the main aetiology of PPH, whatever the mode of delivery and severity. The risk factors identified were those classically described in the literature. CONCLUSION: In these six French perinatal networks, in 2005-2006, the PPH profile was characterized by an incidence of severe forms higher than previous population-based estimates from other countries. This suggests a more frequent aggravation of PPH and the implication of inadequate PPH management.
