[Cesarean sections in the Centre-Val de Loire region: Practices and indications-the Robson Classification]. / Césarienne en Centre-Val de Loire ­ Pratiques et Indications ­ Classification de Robson.

BACKGROUND: To study the cesarean section (c-section) practices in the French Centre-Val de Loire region: incidence of planned c-section and rate variations between maternities, incidence of potentially avoidable cesarean sections. METHODS: The data were extracted from the 2016 regional birth register, which permitted classification of each planned c-section according to the pre-existing risk of c-section (high or low) as defined by the Robson classification. To enhance the data, especially the indications for c-section, which are not included in the register, a survey was conducted from September 2016 to February 2017 in all of the 20 maternities in the region. RESULTS: In 2016, nearly 26,000 women gave birth in the CVL region, of whom 19.2% by c-section (7.0% planned c-sections). The planned c-section rate was higher for breech presentation and scarred uterus, and decreased according to level of the maternity (I 41% - II 35% - III 32%). Concerning the c-section indications, 1,979 c-sections were studied during the period (18.6% of births), including 762 planned c-sections (7.1% of births). Among them, 246 (32%) were potentially avoidable, mainly isolated indications of scarred uterus with only one previous c-section or breech presentation, and 17 due to unfavorable radiologic pelvimetry in nulliparous women. CONCLUSION: Specific actions were identified: targeted use of radiologic pelvimetry, targeted c-section on scarred uterus with only one previous cesarean section or breech presentation, as recommended by the national guidelines. The Robson classification should be widely used to evaluate and enhance practices, in particularly through painstakingly interpreted inter-maternity comparisons.

In-utero aspiration vs expectant management of anechoic fetal ovarian cysts: open randomized controlled trial.

OBJECTIVE: To assess the efficacy and safety of in-utero aspiration (IUA) of anechoic fetal ovarian cysts. METHODS: This multicenter, prospective, randomized open trial in two parallel groups included women from nine outpatient fetal medicine departments with singleton pregnancy ≥ 28 weeks of gestation and a female fetus with an ultrasound-diagnosed simple ovarian cyst, defined as a single fully anechoic cystic structure measuring ≥ 30 mm. They were allocated randomly to IUA under ultrasound guidance or expectant management. All procedures were performed by trained senior obstetricians. Primary outcome was need for neonatal intervention, by laparoscopy, laparotomy or transabdominal aspiration. Secondary outcomes were in-utero involution of the cyst and oophorectomy at birth. Analyses were conducted according to the intention-to-treat principle. RESULTS: Of 61 participants, 34 were allocated to IUA and 27 to expectant management. Three IUA procedures (9%) could not be performed (one due to fetal position and two due to aspirations being dry). The remaining 31 IUA procedures were uneventful. The incidence of neonatal intervention did not differ significantly between the IUA and the expectant management groups (20.6% vs 37.0%; relative risk (RR), 0.55; 95% CI, 0.24-1.27). Nonetheless, IUA was associated with increased incidence of in-utero involution of the cyst (47.1% vs 18.5%; RR, 2.54; 95% CI, 1.07-6.05) and reduced rate of oophorectomy (3.0% vs 22.0%; RR, 0.13; 95% CI, 0.02-1.03) compared with expectant management. CONCLUSION: IUA of anechoic fetal ovarian cysts, compared with expectant management, was not associated with a reduction in overall neonatal interventions but was associated with a reduced oophorectomy rate.

[Mechanical methods for cervical ripening in France: An evaluation of professional practices]. / Maturation cervicale par méthodes mécaniques en France : évaluation de pratiques professionnelles.

OBJECTIVE: Mechanical methods for cervical ripening are as effective as prostaglandins for the rate of vaginal delivery. Our aim was to study professional practices of mechanical cervical ripening in France. METHODS: A declarative survey was conducted among two groups of maternity units: a sample representative of French maternity units (group 1) and on the whole of type 3 maternity units (group 2). A questionnaire was emailed to physicians of these obstetric units between May and July 2014. RESULTS: Forty-three of the 104 units (41.3%) in the first group and 43 of the 64 units in the second group (67.2%) answered the questionnaire. Among these maternity units, mechanical methods were used respectively in 44.2 and 69.8% of the establishments. The two main devices used were the trans-cervical balloon catheter and the Foley catheter. The main indication for mechanical methods was induction of labor with prior caesarean. In case of induction of labor, a prior caesarean and a Bishop score < 7, in the first group, 46.6% of the maternity units did a caesarean, 32.3% performed an induction of labor with mechanical methods, 13.9% with oxytocin and 6.9% with prostaglandins. In the second group, 25.6% of maternity units performed a caesarean, 53.6% used mechanical methods, 9.3% used oxytocin and 11.6% used prostaglandins. CONCLUSION: In France nearly half of the maternity units and nearly three-quarters of type 3 maternity units say they use mechanical cervical ripening, mainly used in case of prior caesarean.

[Selective termination of pregnancy for monochorionic twins: a national survey of professional practice]. / Interruption sélective sur grossesse gémellaire monochoriale: étude nationale des pratiques des Centres Pluridisciplinaires de Diagnostic Prénatal.

OBJECTIVES: Selective Termination of Pregnancy (STOP) for discordant fetal condition in monochorionic twin pregnancy is a rarely performed procedure raising technical and ethical considerations. There are no epidemiological data available in France concerning STOP and no guideline or scientific consensus on how or when to perform has been published. MATERIALS AND METHODS: We conducted a study of national practice using a declarative questionnaire sent by e-mail to each medical coordinator of every 48 Multidisciplinary Center for Prenatal Diagnosis in France. The questions focused on the issues of 2010 and 2011. Two reminders were sent in case of no answer. RESULTS: The response rate to the questionnaire was 56 %; 81 % of centers have experienced at least once during the two years 2010-2011 a discordant fetal anomaly in monochorionic twin pregnancy. Only 59 % of centers perform all the techniques of STOP. When interruption of the umbilical blood flow is considered, bipolar forceps coagulation is the most used (75 %). Achieving STOP during a cesarean section is a common practice (75 % of centers). Locoregional anesthesia is the preferred mode of anesthesia for STOP. DISCUSSION AND CONCLUSION: STOP on monochorionic twin pregnancy is not practiced in all Multidisciplinary Center for Prenatal Diagnosis in France. The most widely practiced and most studied technique is bipolar forceps coagulation. The option of an expectant management should always be considered and its risks should be balanced with those of STOP. The practice of STOP during cesarean section is not unusual.

[Delivery of the IUGR fetus]. / Modalités de naissance du fœtus porteur d'un RCIU.

OBJECTIVE: The purpose of this paper is to review available data regarding the management of delivery in intra uterine growth retarded fetuses and try to get recommendations for clinical obstetrical practice. MATERIALS AND METHODS: Bibliographic research performed by consulting PubMed database and recommendations from scientific societies with the following words: small for gestational age, intra-uterine growth restriction, fetal growth restriction, very low birth weight infants, as well as mode of delivery, induction of labor, cesarean section and operative delivery. RESULTS: The diagnosis of severe IUGR justifies the orientation of the patient to a referral centre with all necessary resources for very low birth weight or premature infants Administration of corticosteroids for fetal maturation (before 34 WG) and a possible neuroprotective treatment by with magnesium sulphate (before 32-33 WG) should be discussed. Although elective caesarean section is common, there is no current evidence supporting the use of systematic cesarean section, especially when the woman is in labor. Induction of labor, even with unfavorable cervix is possible under continuous FHR monitoring, in favorable obstetric situations and in the absence of severe fetal hemodynamic disturbances. Instrumental delivery and routine episiotomy are not recommended. For caesarean section under spinal anesthesia, an adequate anesthetic management must ensure the maintenance of basal blood pressure. CONCLUSION: Compared with appropriate for gestational age fetus, IUGR fetus is at increased risk of metabolic acidosis or perinatal asphyxia during delivery.

[Cervical ripening with balloon catheter for scared uterus: a three-year retrospective study]. / Maturation cervicale par sonde à ballonnet sur utérus cicatriciel : étude rétrospective sur trois ans.

OBJECTIVES: To evaluate, for women with scared uterus, the mechanical cervical ripening with balloon catheter. METHODS: We conducted a retrospective study of our practice of ripening for scared uterus from january 2010 to august 2012. Feasibility, Bishop's score, birth modalities and complications for mothers and babies during this ripening were studied. RESULTS: Thirty-nine medical files were analysed. All patients could have mechanical ripening independently of the internal os status (open or not). The cervical ripening with balloon catheter improved Bishop's score before induction of labour, from 3.54 ± 1.23 to 5.38 ± 1.47 (p=0.02). 64.1% of women had a vaginal delivery. Concerning the predictive factors for vaginal delivery, we only found significant influence of a body mass index less than 30kg/m² (p=0.03). We didn't find any maternal or neonatal complications in our population. CONCLUSION: Mechanical ripening for scared uterus seems to be a useful option to improve vaginal delivery without increasing maternal and foetal morbidity. Anyway, these results have to be confirmed by a randomized controlled trial on a specific scared uterus population.

[Ultrasound in monitoring of the second stage of labour]. / Le suivi échographique de la deuxième partie du travail.

In the second stage of labor, fetal head rotation and fetal head position are determinant for the management of labor to attempt a vaginal delivery or a cesarean section. However, digital examination is highly subjective. Nowadays, delivery rooms are often equipped with compact and high performance ultrasound systems. The clinical examination can be easily completed by quantified and reproducible methods. Transabdominal ultrasonography is a well-known and efficient way to determine the fetal head position. Nevertheless, ultrasound approach to assess fetal head descent is less widespread. We can use translabial or transperineal way to evaluate fetal head position. We describe precisely two different types of methods: the linear methods (3 different types) and the angles of progression (4 different types of measurement). Among all those methods, the main pelvic landmarks are the symphysis pubis and the fetal skull. The angle of progression appears promising but the assessment was restricted to occipitoanterior fetal position cases. In the coming years, ultrasound will likely play a greater role in the management of labor.

[Predictive factors for fetal tolerance to cordocentesis: a monocentric retrospective study]. / Facteurs prédictifs de tolérance fœtale à la cordocentèse : étude rétrospective monocentrique.

OBJECTIVES: Indications for fetal blood sampling (FBS) are getting more limited. In this context, we aimed to evaluate fetal loss and morbidity associated with FBS and to precise the predictive parameters for fetal complications. More than a retrospective evaluation of our practices, the final end point of our study was to better inform the patients coming to our centre. PATIENTS AND METHODS: Retrospective monocentric cohort (Canadian Task Force classification II-2) of the 99 FBS performed between April 2004 and June 2010 on 80 fetuses, after excluding the procedures done for termination of pregnancy. The main clinical outcome was a composite outcome criteria for fetal tolerance including cesarean section for abnormal non stress test within the 24 hours, or any event responsible of a modified obstetrical management during the 14 day following FBS. RESULTS: Mean maternal age at FBS was 30 years ± 5.13 SD and parity was 2.49 ± 1.38 SD. FBS was performed by an experienced operator in 86.5% of cases (CI 95%, 78-92.6); with a single insertion in 83.3% of circumstances (CI 95%, 74.4-90.2). The mean duration was 11 min ± 6.37 SD. The total rate of intrauterine death, in our series, was 7.1% (CI 95%, 2.9-14), including all reported fetal demise within the 14 days after FBS, whatever the relation with the procedure. Our study demonstrated a 9.1% occurrence of post-FBS altered CTG fetal testing (CI 95%, 4.2-16.6), half of it with spontaneous resolution. The rate of severe complications (main clinical outcome) was 11.1% (CI 95%, 5.7-19) including one fetal death liable to FBS and 10 emergency caesarean sections: 5.1% for fetal bradycardia (CI 95%, 1.7-11.4), 2% for placental abruption (CI 95%, 0.2-7.1), 2% for premature preterm rupture of membranes (CI 95%, 0.2-7.1) and 1% for significative umbilical cord bleeding (CI 95%, 0-5.5). Univariate factor analysis highlights 4 parameters for impaired fetal tolerance; a prolonged procedure, presence of low fetal platelets (<30.10(9)/L); and FBS performed for fetal anaemia during Parvovirus B19 infection or allo-immune thrombocytopenia. DISCUSSION AND CONCLUSION: FBS remains a tricky procedure with a substantial risk of fetal loss or complications especially when performed on high-risk fœtuses. The length of the procedure should be shortened as much as possible (trained operator, postponed procedure when all favourable condition are not available). Fetal thrombocytopenia is a meaningful risk factor encouraging carefulness when exploring allo-immune fetal thrombocytopenia.

[Prenatal management of a fetal pericardial teratoma with pericardio-amniotic shunting: a case report]. / Prise en charge prénatale d'un tératome péricardique par drainage péricardio-amniotique : présentation d'un cas.

Fetal intrapericardial teratomas are uncommon and usually benign. Their histology is the same as that of teratomas located elsewhere. They may cause death from non-immune hydrops fetalis and cardiac tamponade. We report a case that was successfully managed prenatally by placement of a pericardial amniotic shunt.

[Management of obstetric cholestasis in France: A national survey of obstetrical practice]. / Prise en charge de la cholestase intrahépatique gravidique en France : enquête nationale des pratiques auprès des gynécologues-obstétriciens.

OBJECTIVE: Intrahepatic cholestasis of pregnancy (ICP) is the most commonly encountered pregnancy-specific liver disease. This condition, with no proven maternal morbidity, has been associated with an increased risk of prematurity and intrauterine fetal death. There is, to date, no scientific obstetrical guideline for clinical practice in France. The objective of our study was to precise, in this situation, how French obstetricians manage patients suffering from ICP. METHODS: We carried out, during 2010, a national descriptive practice survey of ICP management in France in association with the "Collège national des gynécologues-obstétriciens français". An inquiry form with 27 multiple-choice questions was sent to all obstetricians and gynecologist officiating in a maternity hospital recorded by the French Ministry of Health. The participants answered questions regarding diagnosis, perinatal management and treatment of ICP. Only the first answer received from each maternity hospital was analyzed. RESULTS: Of the 575 maternity hospitals, 275 (41.6%) responded after one mail recovery. Among them, almost half used a standardized management protocol for ICP. In most of the cases, perinatal management was performed by obstetricians alone (73%), and in only 20% of the cases in collaboration with the specialist in hepatology. Induction of labor at 37-38 weeks was the most common policy for the majority of respondents (92.4%). CONCLUSION: This is the first French national survey for ICP management. This study demonstrated that ICP is, in most of the cases, managed by the obstetrician alone, and that fetal risks warrants an active management with induction of labor in late pregnancy.

[Delivery in lateral position. Comparative study in low risk pregnancy between lateral and dorsal position for the delivery in eutocic vaginal birth]. / Accouchement sur le côté. Étude comparative chez les grossesses à bas risque entre décubitus latéral et dorsal lors de la phase expulsive des accouchements eutociques.

OBJECTIVE: For several years in French labour wards, delivery in the lateral decubitus position (LP) has raised great interest. We wanted to assess perineal outcomes and neonatal morbidity following delivery in the lateral LP compared to the dorsal decubitus position (DP). PATIENTS AND METHODS: Two teams of midwives, in a private and in a public hospital, performed a total of 6800 deliveries in the area of Tours following a training session on the techniques of delivery in the lateral decubitus position. The design was a retrospective case-control study including patients with low obstetrical risks and normal vaginal delivery. We included 645 patients who gave birth from May 1st to September 30th, 2007. RESULTS: We showed a significant difference in perineum outcomes, with a lower episiotomy rate (56.7% in LP/40.7% in DP, P=0.0001), a higher rate of intact perineum (56.7% in LP/40.7% in DP, P=0.0001) and no differences with respect to perineal laceration. These differences were significant in primiparous (intact perineum: 46.8% in LP/20.2% in DP, P=0.004; episiotomy: 17% en DL/44.7% en DD, P=0.006) and secondiparous patients (episiotomy: 8.6% in LP/30.7% in DP, P=0.0001). We showed significant differences in fetal heart abnormalities during labour in favour of the lateral decubitus position (no anomaly, P=0.00004; separated decrease, P=0.04; bradycardia, P=0.0009; early decrease, P=0.04). DISCUSSION AND CONCLUSION: The neonatal mortality and morbidity did not differ between delivery positions. The lateral position seems to be protective for the perineum without affecting neonatal outcome. Incorporating lateral decubitus deliver into daily practice is possible in large groups of midwives after appropriate training.

[Antenatal screening for HIV: knowledge, attitudes, beliefs and practices of pregnant women. Analysis of current practices and the impact of setting up an informative brochure]. / Dépistage anténatal du VIH: connaissances, attitudes, croyances et comportements des femmes enceintes. Analyse des pratiques actuelles et impact de la mise en place d'un dépliant informatif.

OBJECTIVES: To assess the impact of an information leaflet on the behavior and knowledge of pregnant women about the risks of HIV infection during pregnancy. PATIENTS AND METHODS: Comparative prospective study conducted in two phases from March 1 to September 30, 2007 on patients presenting for the first time in antenatal care at the Maternity Hospital of Tours (n=539). During the first phase, only a self-questionnaire was given during the second an informative brochure has been attached to the questionnaire. RESULTS: Currently 25.1% of pregnant women have not made a test during their pregnancy. This rate decreases to 12.9% when the test is routinely offered. It falls to 8.2% with the introduction of an informative brochure. The test was imposed in 28.7% of patients. Some risks of transmission of HIV, including those specific to pregnancy, are undervalued. A negative test before the pregnancy is the main reason for refusal of antenatal screening. A high level of education was the only risk factor identified for refusal. They are better informed as shown by the higher rate of correct answers about the risks of HIV transmission and antenatal screening. We hypothesize that the women who pursued graduate studies evaluate the risk of infection before accepting or refusing the test. CONCLUSION: The study shows that the distribution of an informative brochure on advanced prenatal screening, increased the number of women performing the test and improved their knowledge about risks of transmission, especially from mother to the child.

[How long can we wait at full dilatation. A study of maternal and neonatal morbidity related to the duration of the second stage of labour in nulliparous women]. / Combien de temps peut-on attendre à dilatation complète? Analyse de la morbidité maternelle et foetale selon la durée de la seconde phase du travail chez la primipare.

OBJECTIVES: To determine the statistical association, in nulliparous patients, between maternal and fetal morbidity and the length of the second stage of labour. To precise whether a prolongation of this period of more than 2h may results in a dramatic increase of this morbidity. MATERIALS AND METHODS: Retrospective cohort study conducted in a level III referral centre between 1 April 2004 and 30 April 2005, including all nulliparous, term, cephalic, live singleton birth without fetal malformation in patients reaching the second stage of labour (n=1191). All deliveries were performed without restrictions in the length of the second stage of labour in the absence of fetal heart rate abnormalities. Maternal and neonatal morbidity were examined according to the duration of the second stage of labour with univariate analysis and after statistical adjustment with multivariate logistic regression for potential confounding variables. RESULTS: Global maternal morbidity ranged from 5.7% after 1h to 20.4% after more than 3h of full cervical dilatation. After a second stage duration of 2h, each additional completed hour resulted in a significant increase in global maternal morbidity (OR 1.78; IC 95% [1.59-1.97]), postpartum haemorrhage (OR 1.72; IC 95% [1.21-2.23]) and level three or four perineal lacerations (OR 1.24; IC 95% [1.7-1.41]). In the same time, caesarean section rate (OR 2.09; IC 95% [1.84-2.34]) and operative vaginal deliveries (OR 1.82; IC 95% [1.59-2.05]) increased significantly. Conversely, our study didn't demonstrate any significant association between neonatal morbidity and the length of the second stage of labour. CONCLUSION: Our study confirmed the association between the duration of the second stage of labour and the increase of maternal but not neonatal morbidity. Such an association, predominantly after 3h spend at full cervical dilatation, needs to be taken into account and, according to our experience, may justify caesarean section.

[Breast angiosarcoma: sonographic, mammographic and MRI features]. / Angiosarcome du sein: caractéristiques échographiques, mammographiques et IRM.

The purpose of this paper is to report the clinical, imaging (sonographic, mammographic and MRI) and pathological features of breast angiosarcoma, a rare but aggressive tumor, based on a review of two cases.

[Prenatal outcome of sex chromosome anomalies diagnosed during pregnancy: a retrospective study of 47 cases]. / Devenir prénatal des anomalies des chromosomes sexuels diagnostiquées pendant la grossesse. Analyse rétrospective de 47 cas]

OBJECTIVE: To study the circumstances of discovery and the prenatal outcome of sex hormone anomalies diagnosed by invasive prenatal techniques during pregnancy and analyze which factors could be implicated in the parents' choice to terminate or carry on with pregnancy. METHODS: We reviewed retrospectively 47 cases of sex chromosome anomalies diagnosed and managed in our prenatal diagnosis unit over a 9-year period between January 1, 1990 and December 31, 1998. Only cases karyotyped in our laboratory and with a complete follow-up were considered. RESULTS: Cytogenic findings were mainly turner syndrome (n=25) and Klinefelter syndrome (n=12). The other karyotypes were the following: 47, XXX (n=6), 47, XYY (n=2), and 49, XXXXY (n=2). Among the 47 pregnancies, 11 (23.4%) were carried to term. The rate of pregnancy termination (68.1%) was high. The decision to terminate varied depending on the abnormal karyotype: 88% for Turner syndrome, 42% for Klinefelter syndrome, 33% for 47, XXX, 50% for 47, XYY and 100% for 49, XXXXY. The pregnancy termination rate was significantly higher when one or more abnormal ultrasound findings was present (92.3% vs 41.2%, p<0.01). CONCLUSION: Our study confirms that termination rates remain high in case of sex hormone anomalies. Associated ultrasonographic findings play a major role in the parents' choice to terminate or carry on with the pregnancy. It would appear that the development of consensual guidelines in pluridisciplinary fetal medicine centers can help reduce the disparities currently observed among French centers in the management of fetuses with sex chromosome anomalies.

[Ultrasonographic diagnosis and prenatal management of fetal ovarian cysts]. / Diagnostic échographique et prise en charge prénatale des kystes ovariens du foetus.

OBJECTIVE OF THE STUDY: To evaluate the outcome of fetal ovarian cysts in relation to their ultrasonic appearance and size. To define, on that basis, the contribution of intrauterine aspiration. MATERIAL AND METHODS: Retrospective study of all ovarian fetal cysts detected by prenatal ultrasound examination (n = 25) during a 4 year period. All these cysts were followed during pregnancy and after delivery until spontaneous or surgical resolution. RESULTS: At the time of prenatal sonographic detection at the mean gestational age of 32 1/2 weeks, the mean cyst diameter was 43+/-17 mm and 36% of all these cysts were already complicated (fluid-debris level, septa or finding of a retracting clot). Among the 16 non-complicated cysts (echolucent and thin-walled) 44% became twisted during the perinatal period irrespective of the size or the time of discovery. At birth, all these complicated cysts underwent surgical treatment and needed oophorectomy or adnexectomy. Surgery was therefore performed in a total of 56% of neonates. The pathologic reports confirm in all cases the benign follicular or follicular lutein nature of the cysts. CONCLUSION: Due to this high rate of mechanical complications, cyst decompression may be considered at the time of diagnosis in case of an anechoic fetal ovarian cyst. The safety and efficacy of this approach, on the cases reported in the literature seem encouraging. Although, a prospective randomized evaluation is needed.

Fetal ovarian cysts: a report of three cases managed by intrauterine aspiration.

Small follicular or functional theca-lutein cysts are a common finding in fetal and neonatal ovaries. After delivery, decrease of hormonal stimulation may lead to spontaneous resolution of the cyst. A high rate of complication has been underlined by recent studies, the most common being ovarian torsion with subsequent loss of the ovary. Because torsion may happen with any size of cyst, however large or small, we suggest in utero decompression even in small fetal ovarian cysts (< 5 cm). We report here three cases of such cysts managed by intrauterine aspiration with good outcome and no further need for neonatal surgery. In all cases cytology of the cyst aspirate demonstrated numbers of granulosa cells and fluid biochemistry showed a high amount of estradiol, progesterone, and testosterone that confirmed the etiology as ovarian. Despite the small size of the cysts, no technical difficulties were encountered and no maternal or fetal morbidity occurred. Prenatal management of fetal ovarian cysts remains controversial, however, and our limited experience needs to be assessed on a larger number of cases.
