RESUMEN
OBJECTIVE: Erythrocyte allo-immunization's rate has decreased but without adapted treatment the prognosis is still poor. The aim of our study was to evaluate the fetal prognosis, the complication's rate and the risk factors of complications of the intrauterine transfusion. METHODS: Retrospective study about 37 fetus and 86 intrauterine transfusions between 2001 and 2017. Our main criterion in judging was the occurrence of procedure related complications: premature membrane rupture or premature delivery within seven days from the procedure, chorioamnionitis, abnormal fetal heart rate indicating an emergency ceasarean section within the 24hours from the procedure, in utero death or neonatal death related to the procedure. RESULTS: The survival rate was about 88.9% with a severe complication's rate of 5.8% per intrauterine transfusion and 13.5% per pregnancy. Intrauterine transfusions before 18 weeks of pregnancies was a complication risk factor: 50% of complications before 18 weeks vs. 1.3%, P=0.8×10-3. On the contrary, hydrops did not seem to be a complication risk factor (16.7% of complication with hydrops vs. 3.9%, P=0.27). The localisation of the needle insertion, intra-abdominal or placental insertion, had no effect on the fetal prognosis. CONCLUSION: Intrauterine transfusion complications are rare and it enhances the fetal prognosis. However, an early procedure is related to a higher rate of complications.

INTRODUCTION: The objective was to report on a consecutive series of monochorionic diamniotic pregnancies complicated by selective Intra-Uterine Growth Restriction (sIUGR) and to describe perinatal outcomes based on whether or not there were umbilical Doppler findings, and specifically to study those pregnancies treated by laser. MATERIAL AND METHODS: This was a retrospective cohort study enrolling monochorionic diamniotic pregnancies presenting isolated sIUGR after 16 weeks' gestation (WG). RESULTS: Of the 25 cases of sIUGR, 16 were type I and 9 type II or III. Types II and III occurred earlier than type I (22.3 versus 24.3 WG), were more severe (discordance of 37% versus 23%), and delivered earlier (31.3 versus 33.9 WG). Survival was 12/18 (66.7%) for types II or III versus 32/32 (100%) for type I. Five laser photocoagulation procedures were attempted and allowed the survival of both twins in 2 cases. Overall survival after laser was 6/10 (60%). DISCUSSION: Isolated sIUGR is associated with high perinatal morbidity and mortality. Laser photocoagulation treatment is feasible and may enable survival of both twins in some cases, but may be technically difficult.

BACKGROUND: High risk of morbidly adherent placenta increased during past years. Their management is controversial. Cesarean hysterectomy, considered the gold standard treatment by American Society, is associated with high risk of maternal morbimortality. Conservative management has been sought to reduce maternal morbidity associated with caesarean hysterectomy while maintaining fertility. It consists of leaving the placenta in place but long-term monitoring. Our main objective was to determine advantage/disadvantage of conservative management on patient with an antenatal diagnosis of placenta accreta, increta or percreta. MATERIAL AND METHODS: This retrospective study included all patients with an antenatal diagnosis of placenta accreta, increta or percreta between 2007 and 2014. Conservative treatment was systematically attempted according to our protocol. The primary outcome was defined as uterine conservation and the secondary outcome as maternal morbimortality defined as any medical or surgical condition occurring after childbirth. RESULTS: Fifteen patients (0.07 % of all living childbirths) were included. Conservative management was successful in 80 % of patients. There was no case of maternal death. Severe post-partum hemorrhage occurred in 4 patients (33.3 %) requiring uterine arteries embolization in one patient and hysterectomy in the 3 others. They underwent immediate blood transfusion of 13.5±4.5 average of red blood cell units. No severe septic condition occurred but 4 patients suffered from endometritis, 2.6±0.5 months after birth requiring intravenous antibiotics treatment in conventional hospitalization. Mean duration for spontaneous abortion of the placenta was 23.0±7.2 weeks. Three spontaneous pregnancies occurred in 2 patients after 19±16.9 months. CONCLUSION: Conservative management seems encouraging but is associated with a non-insignificant risk of secondary complication requiring long-term monitoring in conciliant patients.

OBJECTIVES: Main objective was to compare accuracy of ultrasonography and MRI for antenatal diagnosis of placenta accreta. Secondary objectives were to specify the most common sonographic and RMI signs associated with diagnosis of placenta accreta. MATERIAL AND METHODS: This retrospective study used data collected from all potential cases of placenta accreta (patients with an anterior placenta praevia with history of scarred uterus) admitted from 01/2010 to 12/2014 in a level III maternity unit in Strasbourg, France. High-risk patients beneficiated antenatally from ultrasonography and MRI. Sonographic signs registered were: abnormal placental lacunae, increased vascularity on color Doppler, absence of the retroplacental clear space, interrupted bladder line. MRI signs registered were: abnormal uterine bulging, intraplacental bands of low signal intensity on T2-weighted images, increased vascularity, heterogeneous signal of the placenta on T2-weighed, interrupted bladder line, protrusion of the placenta into the cervix. Diagnosis of placenta accreta was confirmed histologically after hysterectomy or clinically in case of successful conservative treatment. RESULTS: Twenty-two potential cases of placenta accreta were referred to our center and underwent both ultrasonography and MRI. All cases of placenta accreta had a placenta praevia associated with history of scarred uterus. Sensibility and specificity for ultrasonography were, respectively, 0.92 and 0.67, for MRI 0.84 and 0.78 without significant difference (p>0.05). The most relevant signs associated with diagnosis of placenta accreta in ultrasonography were increased vascularity on color Doppler (sensibility 0.85/specificity 0.78), abnormal placental lacunae (sensibility 0.92/specificity 0.55) and loss of retroplacental clear space (sensibility 0.76/specificity 1.0). The most relevant signs in MRI were: abnormal uterine bulging (sensitivity 0.92/specificity 0.89), dark intraplacental bands on T2-weighted images (sensitivity 0.83/specificity 0.80) or placental heterogeneity (sensitivity 0.92/specificity 0.89). Association of two sonographic or MRI signs had the best sensitivity/specificity ratio. DISCUSSION AND CONCLUSION: Ultrasonography and RMI represent two interesting and complementary diagnostic tools for antenatal diagnosis of placenta accreta. Because of its cost and accessibility, ultrasonography remains the first in line to be used for diagnosis. Use of an analytical grid for diagnosis of placenta accreta could be helpful.

Caudal appendage is a rare malformation which has since ever been interesting. We present the case of a girl in which a caudal appendage was discovered before birth. A throughout checking found an extension from this abnormality to the cordal spine. The baby is operated when 2months old. Differential diagnosis are spina bifida, teratoma and pilonidal sinus. Caudal appendage is one of the typical cutaneous finding with underlying spinal dysraphism, such as hair tuft or pigmented macule. The risk is a tethered cord syndrome that can lead to severe complication. The treatment is either surgery or expectation.

PURPOSE: To evaluate the efficacy and safety of induction in women with a single prior Caesarean section. METHODS: This was a cohort study in which we included all singleton pregnancies in patients with a single prior Caesarean who delivered between 2007 and 2012. Methods of induction were ocytocic infusion plus amniotomy (if Bishop score ≥6) or insertion of a Foley catheter (Bishop <6). RESULTS: Of the 2,075 patients included, 806 (38.8 %) had an elective repeat Caesarean, 1,045 (50.4 %) went into spontaneous labour, 89 (4.3 %) were induced by artificial rupture of the membranes and infusion of ocytocics and 135 (6.5 %) were induced using a Foley catheter. Rates of vaginal delivery were 79.2, 79.8 and 43.7 %, respectively. Six cases of uterine rupture were reported in the group of patients who went into spontaneous labour. There was no difference between groups with regard to neonatal morbidity. On multivariate analysis, risk factors for Caesarean delivery were macrosomia (OR 2.04, 95 % CI 1.31-3.18) and induction by Foley catheter (OR 3.73, 95 % CI 2.47-5.62); protective factors were previous vaginal delivery (OR 0.41, 95 % CI 0.29-0.57) and cervical dilatation (OR 0.84, 95 % CI 0.78-0.91). CONCLUSIONS: Uterine induction after a single Caesarean section with ocytocic infusion and amniotomy where the cervix is favourable does not appear to entail any significant added risk in terms of maternal or foetal morbidity. Foley catheter induction is a reasonable option if the cervix is not ripe.

OBJECTIVE: To compare laser data, complications and neonatal outcome in pregnancies that undergo 'early' (≤ 17 weeks' gestation) fetoscopic laser ablation of placental vascular anastomoses for twin-twin transfusion syndrome (TTTS) with those from 'conventional' cases treated after 17 weeks. METHODS: This was a cohort study of data collected prospectively between January 2004 and December 2012. We included monochorionic diamniotic twin pregnancies complicated by TTTS and treated by fetoscopic laser coagulation. Pregnancies were grouped according to laser treatment ≤ 17 gestational weeks or > 17 weeks and obstetric and neonatal outcomes were compared between groups. RESULTS: A total of 178 pregnancies with TTTS underwent laser therapy: 40 at or before 17 weeks and 138 after 17 weeks. There was no statistically significant difference between these two groups with respect to the rate of preterm prelabor rupture of membranes (PPROM), gestational age at PPROM and rate of PPROM occurring in the 7 days following fetoscopic laser coagulation. In the early group, the interval between performing fetoscopic laser coagulation and the time of delivery was significantly longer (104 days vs 74 days, P=0.0002) and the delivery rate within 7 days of laser treatment was significantly lower (2.5% vs 15.9%, P=0.026). There was no significant difference between the two groups with regard to the rates of pregnancy without live birth (15.4% vs 15.4%, P=0.993), with one live birth (84.6% vs 84.6%, P=0.993) and with two live births (64.1% vs 58.1%, P=0.500). CONCLUSION: In the event of early TTTS, fetoscopic laser coagulation is technically feasible before 17 gestational weeks and obstetric and neonatal outcomes are comparable with those in cases of laser treatment performed after 17 weeks.

OBJECTIVE: To evaluate the prognostic value of the Children's Hospital Of Philadelphia (CHOP) cardiovascular score and the modified myocardial performance index (MPI), in determining the risk of recipient fetal loss in twin-to-twin transfusion syndrome (TTTS). METHODS: This cohort study was based on data collected prospectively from 105 pregnancies complicated by TTTS (Quintero stages I-IV) and treated with laser photocoagulation between May 2008 and February 2013. Fetuses underwent detailed anatomical and Doppler ultrasonography with cardiac assessment as part of routine care. CHOP score and right MPI were calculated and cut-offs selected using receiver-operating characteristics curve analysis. These were compared according to loss of recipient fetus, using univariate and multivariate logistic regression. The correlation between CHOP score, MPI and Quintero stage was determined and we investigated differences in MPI before and after laser coagulation in a cohort of 90 recipient fetuses. RESULTS: Rates of recipient fetal loss were significantly higher when the CHOP score was ≥ 3 (39.5% vs 12.9%, P = 0.002) and when MPI z-score was > 1.645 (34.5% vs 10.6%, P = 0.004). After adjustment for Quintero stage, the risk of recipient fetal loss remained significantly higher when the CHOP score was ≥ 3 (odds ratio, 3.09; 95% CI, 1.035-9.21). There was a positive correlation between CHOP score, MPI and Quintero stage. MPI was significantly lower after compared with before laser coagulation. CONCLUSION: CHOP score and MPI are predictors of recipient fetal loss in TTTS and may be used to supplement Quintero's classification.

Prematurity is the chief cause of neonatal morbidity and mortality. The objective of this study is to review the different methods for predicting preterm delivery in asymptomatic pregnant women and in situations of threatened preterm delivery. A search of the PubMed/Medline database was carried out for the years 1980-2012. We included studies for predicting preterm birth in asymptomatic and symptomatic patients. Models for predicting preterm delivery based on maternal factors, cervical length and obstetric history in first trimester of pregnancy is a valuable avenue of research. Nevertheless, prediction accuracy still needs to be improved. In the second and third trimesters, routine digital vaginal examination is of no value in asymptomatic women. Echography of the cervix is not useful except in patients with a history of late miscarriage or preterm delivery in order to offer them a preventive treatment. In symptomatic women, the combination of digital vaginal examination, cervical echography and fibronectin gives the best predictive results. Electromyography of the uterus and elastography of the cervix are interesting avenues for future research. Identifying patients at risk of preterm delivery should be considered differently at each stage of pregnancy.

OBJECTIVES: To update knowledge on placental abruption because there are few recent series published although the perinatal care has progressed. PATIENTS AND METHODS: A retrospective observational study has been conducted on 100 consecutive cases of abruptio placentae, occurring from January 2008 to June 2011, in the two maternity units of the University Hospital of Strasbourg (France). RESULTS: One hundred and five births among which five twin pregnancies were included. Clinical context was evident in 91% of cases, but the classic clinical triad was present in only 4% of cases. Clots were found at immediate placenta examination in 77% of cases. Pathological diagnosis was directly in accordance with clinical diagnosis in half the cases. Mean date of childbirth was 33 weeks of amenorrhea and 6 days. Sixty-seven patients gave birth prematurely. Among them, 50 patients delivered before 34 weeks. Sixty caesareans were performed in emergency before labor, including 47 with general anesthesia. Twelve patients had post-partum haemorrhage and ten coagulation disorders. There was no maternal death. Perinatal mortality was 19% with 13 fetal deaths in utero (12.4%), four children born in an apparent death state with resuscitation failure (3.8%) and three neonatal deaths (2.8%). DISCUSSION AND CONCLUSION: Placental abruption is a serious and unpredictable situation. Joint medical care of obstetricians and intensivists is often required. Perinatal mortality mainly occurs in utero.

OBJECTIVE: Noonan syndrome is a frequent genetic disorder with autosomal dominant transmission. Classically, it combines postnatal growth restriction with dysmorphic and malformation syndromes that vary widely in expressivity. Lymphatic dysplasia induced during the embryonic stage might interfere with tissue migration. Our hypothesis is that the earlier the edema, the more severe postnatal phenotype. METHOD: This retrospective study analyzed data from all 32 cases of Noonan syndrome diagnosed in the Medical Genetics Department of Hautepierre Hospital in Strasbourg, France, between 1995 and 2011. The postnatal evolution of Noonan syndrome was compared according to the presence of at least one prenatal ultrasound feature of lymphatic dysplasia. RESULTS: The most frequent prenatal ultrasound features found were increased nuchal translucency, cystic hygroma and polyhydramnios; their global prevalence was 46.4%. The presence of these features was not significantly associated with the postnatal phenotype of Noonan syndrome. CONCLUSION: The results of our study indicate that prenatal ultrasound features of lymphatic dysplasia do not predict an unfavorable postnatal prognosis for Noonan syndrome.

OBJECTIVES: To review clinical and epidemiologic data of orofacial clefts and to evaluate the efficacy and the impact of prenatal diagnosis. MATERIAL AND METHODS: A population-based retrospective study was carried out on data from the Congenital Malformations of Alsace Registry (France) between 1995 and 2006. RESULTS: A total of 321 orofacial clefts were recorded (overall prevalence, 2.1 per 1000), divided into cleft lip (CL) or cleft lip palate (CLP) (204 cases) and cleft palate (117 cases). The cleft lip and cleft lip palate CL±P sex-ratio was 1.87, whereas the CP sex-ratio was 1. CLs were more often unilateral than CLPs (79% versus 59%). CLs were unilateral in 79% of the cases (60/76), bilateral in 20% of the cases (15/76), and median in 1% (1/76); 55% of the unilateral CLs were right and 45% were left. CLPs were unilateral in 59% of the cases (76/128), bilateral in 39% of the cases (50/128), and median in 2% (2/128); 45% of the unilateral CLPs were right and 55% were left. The 117 CPs were divided into 50 clefts of the total palate (43%) and 67 clefts of the posterior palate (57%); 25 cases (21%) of Pierre Robin sequence were collected. Sixty-six percent of CL±P (134/204) were associated with other congenital anomalies, including chromosome abnormality in 31 cases and identified monogenic syndrome or association in 12 cases. The most frequent chromosome abnormalities were 16 cases of trisomy 13 and 7 cases of trisomy 18. No cases of 22q11.2 microdeletion or duplication were detected among CL±P. Monogenic syndromes were identified in 6% (12/204) of CL±P cases: Van der Woude syndrome (2 cases); CHARGE syndrome (2 cases); ectrodactyly, ectodermal dysplasia, and cleft/lip palate (EEC) syndrome (2 cases); branchiooculofacial (BOF) syndrome (1 case); Treacher-Collins syndrome (1 case); Nager syndrome (1 case); Goldenhar syndrome (1 case); holoprosencephaly spectrum (1 case); and Meckel syndrome (1 case). Forty-two percent of CPs (49/117) were associated with other congenital anomalies; chromosome abnormality was identified in 12 cases and monogenic syndrome was diagnosed in 14 cases. The most frequent chromosome abnormality was 22q11 microdeletion (5 cases). Monogenic syndromes were recognized in 12% of the CP cases (14/117): fragile X syndrome (2 cases), Meckel syndrome (2 cases), Orofaciodigital syndrome type I (OFD1) (1 case), Stickler syndrome (1 case), Larsen syndrome (1 case), Kniest syndrome (1 case), Cornelia de Lange syndrome (1 case), thanatophoric dysplasia (1 case), other unknown bone chondrodysplasia (1 case), Fryns syndrome (1 case), fetal akinesia sequence (1 case), and Silver-Russel syndrome (1 case). Fifty-two percent of CL cases (106/204) were prenatally diagnosed. An increasing tendency was observed between the 1995-2000 and 2001-2006 periods with a detection rate increasing from 47% to 56%. During the whole period, only 1 case of CP was prenatally diagnosed. Eighty-two percent of all cases (263/321) were livebirths; 8 stillbirths were reported (2%); 50 syndromic or associated cases (16%) led to medical abortion (no termination of pregnancy was performed for isolated cleft). CONCLUSION: Orofacial clefts are a frequent malformation with a total prevalence of 2.1 per 1000 total births. Sonbographic prenatal diagnosis of orofacial clefts remains difficult with a mean detection rate about 50% for CL±P and is extremely rare for CP. Associated malformations and genetic syndromes are frequent and require a systematic survey. This study also highlights the different pathogenic background of CL±P compared to CP, regarding the sex-ratio and the proportion and type of associated malformations.

OBJECTIVES: To report pre- and post-surgical datas of large series of severe twin-to-twin transfusion syndrome (TTTS) managed with laser ablation surgery in our centre, to evaluate the incidence of complications, perinatal outcome and to compare with other cohorts. PATIENTS AND METHODS: Observational study of 100 cases of TTTS consecutively treated with fetoscopic laser coagulation between January 2004 and April 2010 in CMCO-SIHCUS of Schiltigheim. RESULTS: There are nine stage I, 49 stage II, 38 stage III and four stage 4. Median gestation at time of laser is 20.6 weeks (14-29) whereas median gestation at delivery is 32.6 weeks (16.3-39). Overall perinatal survival rate is 68.5% (137 children over 200). Eighty-five percent have one or more surviving twins. The survival rate is the same for donors and for recipients. Preterm premature rupture of the membranes are observed in 17% of cases and the median gestational age for this complication is 30 weeks (20-34). Cerebral abnormalities are present in 7% of newborns. CONCLUSION: Our results for the management of severe TTTS are comparable to the other reported series. There are still many questions remaining concerning the optimal management of TTTS.

First trimester screening for Down syndrome is yet to become the first intention strategy in France. This screening program at 11-14 weeks of gestation using maternal age, fetal nuchal translucency, maternal serum free beta-human chorionic gonadotropin and pregnancy-associated plasma protein-A has already been validated for a long time by many international studies. It seems to improve detection rate and decrease false positive rates. We report here five years prospective experience.

We report and analyze four new cases of spontaneous twin anemia-polycythemia sequence (TAPS) and discuss antenatal management by fetoscopic laser coagulation for this uncommon form of chronic intertwin transfusion. The clinical course and placental characteristics of four pairs of monochorionic-diamniotic (MCDA) twins with spontaneous TAPS, of which one was treated with fetoscopic laser surgery, are described. For the three cases that did not undergo intrauterine intervention, serial Doppler measurement revealed a gradual increase in the middle cerebral artery peak systolic velocity (MCA-PSV) in the donor and a concomitant decrease in the recipient. These twins were born at between 32 and 34 weeks' gestation by Cesarean section. At birth, the donor twins were severely anemic and the recipient twins were polycythemic. Placental injection studies revealed a few small arteriovenous (AV) and venoarterial anastomoses. In the fourth case, because of the high suspicion of TAPS on MCA-PSV data at 24 weeks' gestation, fetoscopic laser coagulation of three small AV anastomoses was successfully performed. No hematological abnormalities were detected at birth. TAPS is a newly described form of chronic twin-to-twin transfusion associated with chronic anemia in the donor and polycythemia in the recipient, without twin oligo-polyhydramnios sequence (TOPS). The monitoring of MCDA pregnancies should include measurement of MCA-PSV in both fetuses even in the absence of intertwin discordance in amniotic fluid volume. Early detection of TAPS could indicate fetoscopic laser coagulation of AV anastomoses.

Congenital granular epulis is a rare benign tumour situated on the alveolar ridge, which usually presents as a single tumour of variable size. Prenatal diagnosis of epulis has rarely been reported in medical literature. A possible complication is airway obstruction, which is essentially determined by the size of the tumour. Because of the potential risk of neonatal respiratory distress, prenatal diagnosis is valuable in the organization of a safe delivery. The case presented here is the prenatal diagnosis of a congenital epulis discovered in the 32nd week of pregnancy.

UNLABELLED: The causative mechanisms of congenital heart defects remain unclear and little is known about the respective implication of chance, genetics and environment, though recent findings in molecular biology may provide further insight into understanding the pathophysiologic basis of congenital heart diseases. CASE REPORT: We report the exceptional but significant case of monozygotic twins both affected by tetralogy of Fallot, for whom prenatal diagnosis ruled out 22q11 microdeletion. CONCLUSION: We discuss how far this observation is consistent with the latest hypothesis, which emphasizes the leading role of genetic factors. Several genes indeed, either separately or in combination, could be responsible for those defects, even if other influences may still come into play.

OBJECTIVE: To assess the association between the occurrence first of preeclampsia and antiphospholipid antibodies. METHODS: We conducted a prospective case-control study of 180 pregnant women with their first incidents of preeclampsia and no histories of thrombosis or systemic autoimmune diseases. Preeclampsia (n = 180) was defined as blood pressure (BP) at least 140/90 mmHg after 20 weeks' gestation and proteinuria at least 0.3 g per 24 hours. Two control subjects were matched to each case (n = 360). They were pregnant women without hypertension or proteinuria and without histories of thrombosis or systemic autoimmune disease. Lupus anticoagulant (activated partial thromboplastin time, diluted thromboplastin time, platelet neutralization procedure) and anticardiolipin antibodies (immunoenzymatic assays) were assessed in both groups, and the coagulation state (levels of thrombin-antithrombin III complexes, fragments 1 + 2 of prothrombin) was also evaluated. The analysis design was a sequential plan with 5% type I error and 95% power. RESULTS: There was no association between antiphospholipid antibodies and preeclampsia. The odds ratio for the association was 0.95 (95% confidence interval 0.45, 2.61). Antiphospholipid antibodies were detected in eight of 180 preeclamptic women and in 19 of 360 controls. In contrast, there was a clear, confirmed activation of coagulation during preeclampsia. CONCLUSION: Despite evidence of a prothrombotic state during preeclampsia, it is unlikely that antiphospholipid antibodies (lupus anticoagulant and anticardiolipin antibodies) represent risk factors for preeclampsia among women with no previous preeclampsia and no histories of thrombosis or systemic autoimmune disease.

The purpose of this study was to evaluate the foetal sonographic efficiency for prenatal diagnosis of osteochondrodysplasias. Forty-seven prenatal and postnatal cases diagnosed between January 1993 and December 1998 in the referral sonographic centres of Strasbourg were studied. All cases were reviewed retrospectively and the prenatal ultrasound findings and diagnosis were compared to the postnatal or post-mortem diagnosis. Each case was studied by ultrasonographers, geneticists, radiologists, and foetopathologists. Final diagnosis was based on clinical examination, skeletal survey and molecular testing as deemed necessary. Routine screening and dating was the indication for foetal sonography in 72% (32/47) of our cases. The most likely time of diagnosis was between 16 and 24 weeks of gestation (17 out of 47 cases, 36%), which corresponds to the time of foetal anomaly sonographic scan in France. The other cluster of cases (12 among 47, 26%) was disclosed before 16 weeks of gestation. These results illustrate the importance of a detailed evaluation of the limbs during sonographic examinations of first and second trimesters of pregnancy. While the identification of skeletal dysplasias was relatively easy in our study, the ability to make an accurate specific antenatal diagnosis was more difficult. An accurate diagnosis was proposed in 28 of the 47 cases (60%). In 19% of the cases (9/47), the prenatal diagnosis was not accurate; in 21% of the cases (10/47), the prenatal diagnosis was imprecise. In 45 of the 47 cases (96%) prenatal foetal scan correctly predicted the prognosis.
