Abstract
Congenital diaphragmatic hernia (CDH) is a life-threatening birth defect with significant morbidity and mortality. The prenatal management of a pregnancy with a fetus affected with CDH is complex and requires a multi-disciplinary team approach. An improved understanding of prenatal diagnosis and management is essential to developing strategies to optimize outcomes for these patients. In this review, we explore the current knowledge on diagnosis, severity stratification, prognostic prediction, and indications for fetal intervention in the fetus with CDH.

Abstract
OBJECTIVE We aim to provide a template structured report of fetal Magnetic Resonance Imaging in congenital diaphragmatic hernia (CDH) that was locally validated by the CDH study group in Mannheim. METHODS A selection of 50 fetal MRIs of patients with an isolated diaphragmatic hernia and associated radiology reports from five different senior radiologists from a single center resulted in a primary structured report, which was put into practice by using dedicated software. A questionnaire survey of the interdisciplinary CDH study group Mannheim was used to adapt the report to the clinical requirements. RESULTS There was a huge variability in how deep the free text reports go into detail. The side of the hernia was named in 94% of cases. In 58%, both the lung volume and the total lung volume were reported. A comparison with the expected lung volume was reported in 66% of cases. Additional findings, such as herniated organs, were reported in 96% of cases. Overall satisfaction with the newly established structured report was high within the CDH study group with a mean of 4.7. CONCLUSIONS The use of the structured report of this study can optimize the interdisciplinary dialog, the standardization of report content, increase report completeness and improve quality.

Termination of pregnancy after a prenatal diagnosis of congenital diaphragmatic hernia: Factors influencing the parental decision process. Prenat Diagn 2023; 43:95-101. [PMID: 36443507 PMCID: PMC10107614 DOI: 10.1002/pd.6274] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 11/09/2022] [Accepted: 11/22/2022] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To evaluate the incidence of termination of pregnancies (TOP) and factors associated with the decision for TOP in prenatally detected congenital diaphragmatic hernia (CDH). STUDY DESIGN Single-centre retrospective cohort includes all prenatally detected CDH cases born between January 2009 and December 2021. Parental factors, such as parity, and fetal characteristics, such as disease severity, were collected. Descriptive statistics were used to present the data. Differences between terminated and continued pregnancies were analysed. RESULTS The study population consisted of 278 prenatally detected CDH cases of which 80% detected <24 weeks of gestation. The TOP rate was 28% in cases that were detected <24 weeks of gestation. Twenty continued pregnancies resulted in either intrauterine fetal demise (n = 6), preterm birth <24 weeks (n = 2), or comfort care after birth (n = 12). The survival rate was 70% in the remaining 195 live born cases. Factors associated with the decision for TOP were additional fetal genetic or anatomical abnormalities (p < 0.0001) and expected severity of pulmonary hypoplasia in left-sided CDH (p = 0.0456). CONCLUSION The decision to terminate a pregnancy complicated by fetal CDH depends on the severity of pulmonary hypoplasia and the presence of additional abnormalities. This emphasises the importance of early referral to expertise centres for detailed evaluation and multidisciplinary counselling.

Abstract
Congenital diaphragmatic hernia (CDH) is a rare birth defect characterized by incomplete closure of the diaphragm and herniation of fetal abdominal organs into the chest that results in pulmonary hypoplasia, postnatal pulmonary hypertension owing to vascular remodelling and cardiac dysfunction. The high mortality and morbidity rates associated with CDH are directly related to the severity of cardiopulmonary pathophysiology. Although the aetiology remains unknown, CDH has a polygenic origin in approximately one-third of cases. CDH is typically diagnosed with antenatal ultrasonography, which also aids in risk stratification, alongside fetal MRI and echocardiography. At specialized centres, prenatal management includes fetal endoscopic tracheal occlusion, which is a surgical intervention aimed at promoting lung growth in utero. Postnatal management focuses on cardiopulmonary stabilization and, in severe cases, can involve extracorporeal life support. Clinical practice guidelines continue to evolve owing to the rapidly changing landscape of therapeutic options, which include pulmonary hypertension management, ventilation strategies and surgical approaches. Survivors often have long-term, multisystem morbidities, including pulmonary dysfunction, gastroesophageal reflux, musculoskeletal deformities and neurodevelopmental impairment. Emerging research focuses on small RNA species as biomarkers of severity and regenerative medicine approaches to improve fetal lung development.

Abstract
OBJECTIVE To assess the effect of Fetal Endoscopic Tracheal Occlusion (FETO) on neonatal survival in fetuses with left congenital diaphragmatic hernia (CDH) and moderate lung hypoplasia. STUDY DESIGN CDH fetuses with moderate pulmonary hypoplasia (observed/expected lung area to head ratio between 26% and 35%, or between 36% and 45% with liver herniation) were prospectively recruited. Included patients were matched to a control group who were ineligible for FETO. Primary outcomes were survival at 28 days, at discharge, and at 6 months of age, respectively. RESULTS 58 cases were recruited, 29 treated with FETO and 29 matched controls. Median gestational age (GA) at balloon placement and removal were 29.6 and 33.6 weeks, respectively. FETO group showed significantly lower GA at delivery (35.2 vs. 37.1 weeks, respectively, p < 0.01), higher survival at 28 days (51.7 vs. 24.1%, respectively, p = 0.03), at discharge (48.3 vs. 24.1%, respectively, p = 0.06), and at six months of age (41.4 vs. 24.1%, respectively, p = 0.16), and significantly lower length of ventilatory support (17.8 vs. 32.3 days, p = 0.01) and NICU stay (34.2 vs. 58.3 days, p = <0.01) compared to controls. CONCLUSION FETO was associated with a non-significant increase in survival and significantly lower neonatal respiratory morbidity among CDH fetuses with moderate lung hypoplasia.

Abstract
OBJECTIVE To evaluate the neonatal outcome of fetuses with isolated right-sided congenital diaphragmatic hernia (iRCDH) based on prenatal severity indicators and antenatal management. METHODS This was a retrospective review of prospectively collected data on consecutive cases diagnosed with iRCDH before 30 weeks' gestation in four fetal therapy centers, between January 2008 and December 2018. Data on prenatal severity assessment, antenatal management and perinatal outcome were retrieved. Univariate and multivariate logistic regression analysis were used to identify predictors of survival at discharge and early neonatal morbidity. RESULTS Of 265 patients assessed during the study period, we excluded 40 (15%) who underwent termination of pregnancy, two cases of unexplained fetal death, two that were lost to follow-up, one for which antenatal assessment of lung hypoplasia was not available and six cases which were found to have major associated anomalies or syndromes after birth. Of the 214 fetuses with iRCDH included in the neonatal outcome analysis, 86 were managed expectantly during pregnancy and 128 underwent fetal endoscopic tracheal occlusion (FETO) with a balloon. In the expectant-management group, lung size measured by ultrasound or by magnetic resonance imaging was the only independent predictor of survival (observed-to-expected lung-to-head ratio (o/e-LHR) odds ratio (OR), 1.06 (95% CI, 1.02-1.11); P = 0.003). Until now, stratification for severe lung hypoplasia has been based on an o/e-LHR cut-off of 45%. In cases managed expectantly, the survival rate was 15% (4/27) in those with o/e-LHR ≤ 45% and 61% (36/59) for o/e-LHR > 45% (P = 0.001). However, the best o/e-LHR cut-off for the prediction of survival at discharge was 50%, with a sensitivity of 78% and specificity of 72%. In the expectantly managed group, survivors with severe pulmonary hypoplasia stayed longer in the neonatal intensive care unit than did those with mildly hypoplastic lungs. In fetuses with an o/e-LHR ≤ 45% treated with FETO, survival rate was higher than in those with similar lung size managed expectantly (49/120 (41%) vs 4/27 (15%); P = 0.014), despite higher prematurity rates (gestational age at birth: 34.4 ± 2.7 weeks vs 36.8 ± 3.0 weeks; P < 0.0001). In fetuses treated with FETO, gestational age at birth was the only predictor of survival (OR, 1.25 (95% CI, 1.04-1.50); P = 0.02). CONCLUSIONS Antenatal measurement of lung size can predict survival in iRCDH. In fetuses with severe lung hypoplasia, FETO was associated with a significant increase in survival without an associated increase in neonatal morbidity. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVE We have previously described a gestational age-independent sonographic parameter to assess fetal lung growth in the right lung (right quantitative lung index, or QLI-R). The purpose of this study was to develop a similar sonographic parameter to assess the growth of the left lung in the fetus, independent of gestational age, or QLI-L. STUDY DESIGN A new index, the QLI-L was derived using published formulas for the head circumference (HC) and the area of the base of the left lung (LA), with the corresponding percentiles. RESULTS Left lung growth can be expressed using the following formula: QLI-L=LAL(HC12)2. The 50th percentile of the QLI-L remained approximately constant at 1.0 for the GA between 16-32 weeks. A small left lung (<1st percentile) was defined as a QLI-L < 0.5. CONCLUSIONS Fetal left lung growth can be adequately described independent of gestational age using the QLI-L. Further experience is needed to assess the clinical accuracy of the QLI-L in characterizing fetal left lung growth.

Abstract
AIM To present the feasibility, safety and outcomes of fetoscopic endoluminal tracheal occlusion (FETO) for the treatment of severe congenital diaphragmatic hernia (CDH). METHODS This was a single-arm clinical trial of FETO for isolated left-sided CDH with liver herniation and Kitano Grade 3 stomach position (>50% stomach herniation into the right chest). FETO was performed at 27-29 weeks of gestation for cases with observed/expected lung to head ratio (o/e LHR) <25% and at 30-31 weeks for cases with o/e LHR ≥25%. RESULTS Eleven cases were enrolled between March 2014 and March 2016, and balloon insertion was successful in all cases. The median o/e LHR at entry was 27% (range, 20-33%). The median gestational age at FETO was 30.9 (range, 27.1-31.7) weeks. There were no severe maternal adverse events. One fetus died unexpectedly at 33 weeks of gestation due to cord strangulation by the detached amniotic membrane. There were 3 cases (27%) of preterm premature rupture of membranes. In all 10 cases, balloon removal at 34-35 weeks of gestation was successful. The median gestational age at delivery was 36.5 (range, 34.2-38.3) weeks. The median duration of occlusion and the median interval between balloon insertion and delivery were 26 days (range: 17-49 days) and 43 days (range, 21-66 days), respectively. Both the survival rate at 90 days of age and the rate of survival to discharge were 45% (5/11). CONCLUSION The FETO is feasible without maternal morbidity in Japan and could be offered to women whose fetuses show severe isolated left-sided CDH to accelerate fetal lung growth.

Abstract
BACKGROUND Outcomes of infants with congenital diaphragmatic hernia (CDH) are primarily dependent on the severity of pulmonary hypoplasia. It is previously unknown whether postnatal lung growth in infants with CDH represents true parenchymal lung growth or merely an expansion in volume of the existing tissue. We hypothesized that lung volume growth in CDH infants will be accompanied by an increase in lung mass and that CDH infants will demonstrate accelerated catch-up growth of the more hypoplastic lung. METHODS We used fetal and post-CDH repair MRI of 12 infants to measure lung volume and density, which was used to calculate lung mass. RESULTS The average increase in right lung mass was 1.1 ± 1.1 g/week (p = 0.003) and the average increase in left lung mass was 1.8 ± 0.7 g/week (p < 0.001). When the ratio of left-to-right lung mass of the prenatal MRI was compared to post-repair MRI, the ratio significantly increased in all infants with average prenatal and post-repair ratios of 0.30 and 0.73, respectively (p = 0.002). CONCLUSION Lung growth in infants with CDH is indeed growth in lung mass (i.e. parenchyma), and the lungs demonstrate catch-up growth (i.e., increased rate of growth in the more hypoplastic ipsilateral lung).

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) has a high mortality rate, representing a therapeutic challenge. Prenatal diagnosis (PND) is essential in defining optimal perinatal strategy, particularly delivery planning. Hospital Pediátrico de Coimbra is the referral centre for all neonatal surgery, particularly CDH, for the central region of Portugal. The aim was to evaluate clinical management and outcome of newborns with CDH. METHODS An exploratory retrospective study made up of newborns admitted to PICU with CDH was undertaken between January 1995 and December 2014. Two groups were formed based on their year of admission: group A (1995- 2004) and group B (2005- 2014) and were compared. RESULTS The mean birth weight of the 69 newborns admitted was 2.762 ± 696 g; the median of the gestational age was 38 weeks. Associated malformations were observed in 28 (40.5%) and 15 (21.7%) had a right-sided diaphragm defect. The global mortality was 13.0%; in group A was significantly higher than in group B (22.2 vs 3.0%; p = 0.029). A reduction in mortality throughout the years was confirmed after adjusting for POS score (OR = 0.77; 95% CI: 0.62- 0.96, p = 0.021). PND was made in 30.6% of cases in the group A and 66.7% in the group B (p = 0.03). Tertiary perinatal hospital birth was achieved in 60% of newborns in the group A versus 84.8% in group B (p = 0.022). Maximum fraction of inspired oxygen showed a statistically significant difference between the two study groups (60% vs 40%; p = 0.009). CONCLUSIONS A significant decrease in mortality was observed throughout the study. The authors highlight the increase in prenatal diagnosis and an improvement in perinatal care with planning delivery as important contributors to these results.

Abstract
BACKGROUND Lung and pulmonary vascular maldevelopment in congenital diaphragmatic hernia (CDH) results in significant morbidity and mortality. Retinoic acid (RA) and imatinib have been shown to improve pulmonary morphology following prenatal administration in the rat nitrofen-induced CDH model. It remains unclear if these changes translate into improved function. We evaluated the effect of prenatal RA and imatinib on postnatal lung function, structure, and pulmonary artery (PA) blood flow in the rat CDH model. METHODS Olive oil or nitrofen was administered alone or in combination with RA or imatinib to pregnant rats. Pups were assessed for PA blood flow by ultrasound and pulmonary function/morphology following delivery, intubation, and short-term ventilation. RESULTS Neither RA nor imatinib had a negative effect on lung and body growth. RA accelerated lung maturation indicated by increased alveoli number and thinner interalveolar septa and was associated with decreased PA resistance and improved oxygenation. With the exception of a decreased PA pulsatility index, no significant changes in morphology and pulmonary function were noted following imatinib. CONCLUSION Prenatal treatment with RA but not imatinib was associated with improved pulmonary morphology and function, and decreased pulmonary vascular resistance. This study highlights the potential of prenatal pharmacologic therapies, such as RA, for management of CDH.

Abstract
OBJECTIVE Profiling of miR-200b expression and its targets (transforming growth factor [TGF]-β2 and ZEB2) in the surgical rabbit congenital diaphragmatic hernia (DH) model before and after tracheal occlusion (TO). METHODS Thirty-eight timed-pregnant rabbits had left DH creation on gestational day (GD) 23. On GD28, 17 randomly selected fetuses had TO. We harvested fetuses at GD23, GD28, or GD30. We calculated lung-to-body weight ratios, processed lungs for miR-200b in situ hybridization and real-time quantitative polymerase chain reaction, and evaluated effects on downstream targets TGF-β2 or ZEB2. RESULTS We obtained 16 DH fetuses (n = 7 GD28 and n = 9 GD30), 13 TO fetuses (GD30), and 38 control fetuses (n = 15 GD23, n = 11 GD28, and n = 12 GD30). Diaphragmatic hernia lungs were hypoplastic, and TO resulted in control lung-to-body weight ratio levels. Term miR-200b-3p levels were significantly upregulated in the hypoplastic compared with control ipsilateral lung (1.906 ± 0.90 vs 0.7429 ± 0.44) (P < .01). Fetal TO ipsilateral lungs displayed a variable miR-200b response on in situ hybridization and polymerase chain reaction, with levels similar to control and congenital DH lungs. The TGF-β2 was unchanged in hypoplastic and TO lungs, and ZEB2 tended to be reduced in TO compared with DH lungs (1.79 [0.4-2.9] vs 0.73 [0.5-1.4]). CONCLUSIONS Hypoplastic fetal rabbit lungs display upregulation of miR-200b expression although downstream targets are not different from controls. Following TO, fetal rabbit lungs display a variable miR-200b response.

Abstract
BACKGROUND Right-sided congenital diaphragmatic hernias (CDH) and bigger defect sizes have been associated with poorer outcomes. AIM The aim of this study was to evaluate right- and left-sided CDH in terms of size, survival, associated anomalies, and morbidity. MATERIAL AND METHODS We used information from a multicenter, multinational database including patients with CDH born between 2007 and 2015. All infants with data on defect side were included for this analysis. We compared differences in outcomes between right- and left-sided CDH. Further analysis on the association between side, size of the defect, and outcome was performed. RESULTS A total of 3754 cases of CDH were entered in the registry between January 2007 and September 2015, with an overall survival of 71%. Of those, 598 (16%) were right-sided and 3156 left-sided, with a survival rate of 67% and 72%, respectively. Right-sided CDH had a larger proportion of C and D defects (p<0.001 and 0.04, respectively). Survival rates for the same size defect were similar, independent of the side of the defect. Multivariable logistic regression analysis with survival as dependent variable identified a significant correlation with defect size, but not side. CONCLUSIONS The higher proportion of large defects (C & D) in right-sided CDH, not the side itself, accounts for the reported poorer survival in right-sided CDH. LEVEL OF EVIDENCE Level I for a prognosis study - This is a high-quality, prospective cohort study with 99% of patients followed to the study end point (death or discharge).

Abstract
OBJECTIVE To evaluate postnatal lung volume in infants with congenital diaphragmatic hernia (CDH) and determine if a compensatory increase in lung volume occurs during the postnatal period. STUDY DESIGN Using a novel pulmonary magnetic resonance imaging method for imaging neonatal lungs, the postnatal lung volumes in infants with CDH were determined and compared with prenatal lung volumes obtained via late gestation magnetic resonance imaging. RESULTS Infants with left-sided CDH (2 mild, 9 moderate, and 1 severe) were evaluated. The total lung volume increased in all infants, with the contralateral lung increasing faster than the ipsilateral lung (mean ± SD: 4.9 ± 3.0 mL/week vs 3.4 ± 2.1 mL/week, P = .005). In contrast to prenatal studies, the volume of lungs of infants with more severe CDH grew faster than the lungs of infants with more mild CDH (Spearman's ρ=-0.086, P = .01). Although the contralateral lung volume grew faster in both mild and moderate groups, the majority of total lung volume growth in moderate CDH came from increased volume of the ipsilateral lung (42% of total lung volume increase in the moderate group vs 32% of total lung volume increase in the mild group, P = .09). Analysis of multiple clinical variables suggests that increased weight gain was associated with increased compensatory ipsilateral lung volume growth (ρ = 0.57, P = .05). CONCLUSIONS These results suggest a potential for postnatal catch-up growth in infants with pulmonary hypoplasia and suggest that weight gain may increase the volume growth of the more severely affected lung.

Abstract
Purpose: the study of postmortem MRI possibilities for the diagnosis of lung hypoplasia in congenital diaphragmatic hernia.Materials and methods. A comparison of the results of postmortem MRI study and data of pathoanatomical autopsy of 23 newborns was performed. In group I, the bodies of 10 deceased newborns with congenital diaphragmatic hernia without operative intervention were examined. In group II – the bodies of 7 newborns who died after surgery for congenital diaphragmatic hernia. Group III (control) included 6 bodies of newborns without diaphragmatic hernia and signs of lung hypoplasia. Before the autopsy, an MRI study was performed on a 3T Magnetom Verio device (Siemens, Germany) in standard T1 and T2 modes. The volumes of the lungs and chest cavity were calculated in the analysis of the tomograms data and their 3D reconstruction. The stage of the lung development and number of radial alveoli were identified at the microscopic study of histological preparations.Results.As a result of the postmortem MRI study, it was established that the observations of group I are characterized by minimal lung volumes. The mean lung volume on the side of the diaphragmatic hernia was 4.1 times less than the contralateral lung (p < 0.01), and the mean values of the volume of both lungs were 4.6 times less than the corresponding values of the control group (p < 0.01) . The average value of the specific volume of the lungs in newborns who died as a result of congenital diaphragmatic hernia (group I) was 8.8%, which is 4.2 times less than the control group (p < 0.01) and was accompanied by histological signs of hypoplasia. The operation in Group II observations led to an increase in lung size. However, the specific volume of the lungs in this group remained by 18.6% less than the control group, and on histological specimens there were signs of lung hypoplasia.Conclusion.The postmortem MRI of dead newborns allows for an objective quantification of lung volumes and verifies the presence of hypoplasia. This helps to clarify the pathogenesis and determine the immediate cause of death. Indices of specific lung volume relative to the chest cavity of less than 20% indicate lung hypoplasia as the immediate cause of death of the newborn.

Abstract
OBJECTIVES The aim of this study was to follow the course of the superior mesenteric artery (SMA) in first-trimester fetuses to predict the location of the small bowel. Its abnormal course aids in early detection of congenital diaphragmatic hernia (CDH) and assessment of the contents of omphalocele. METHODS The SMA can be easily identified in a sagittal section of the fetus by using color Doppler sonography at the 11- to 14-week scan, and normally, it has a downward course caudally to supply the intestines. The course of the SMA points to the location of the bowel. RESULTS We report a series of 7 cases detected in first trimester with an abnormal course of the SMA, 3 of which had CDH and 4 of which had omphalocele. In CDH, the intestines herniate into the thoracic cavity; hence, the SMA tends to have an upward course toward the thorax. In 4 cases of omphalocele, the SMA follows the exteriorized bowel into the base of the umbilical cord. CONCLUSIONS Second-trimester sonography for detection of congenital malformations is a standardized protocol, but a careful anatomic survey at the 11- to 14-week scan is often rewarding. When there is a suspicion of an intrathoracic mass or a mediastinal shift, the upturned course of SMA serves as a valuable sign in confirmation of CDH. Chromosomal abnormalities are often reported in cases of omphalocele containing small bowel only, and the upward course of the SMA toward the base of the cord helps in its early prenatal diagnosis, which facilitates early genetic assessment in these fetuses.

Abstract
OBJECTIVE The purpose of this study is to compare the observed-to-expected MRI fetal lung volume and the observed-to-expected ultrasound lung-to-head ratio intraindividually for prediction of survival, the need for extracorporeal membrane oxygenation (ECMO) therapy, and the development of chronic lung disease (CLD) at different times of gestation (< 28, 28-32, and > 32 weeks) in fetuses with congenital diaphragmatic hernia (CDH), and to analyze the intraindividual correlation of observed-to-expected MRI fetal lung volume and observed-to-expected ultrasound lung-to-head ratio. MATERIALS AND METHODS Two hundred one fetuses were included in our study. Observed-to-expected MRI fetal lung volume and observed-to-expected ultrasound lung-to-head ratio were calculated for 270 MRI and ultrasound examinations performed within 72 hours of each other. The prognostic accuracy of observed-to-expected MRI fetal lung volume and observed-to-expected ultrasound lung-to-head ratio was assessed by performing ROC analysis. Correlation was determined using linear regression analysis. RESULTS The results revealed statistically significant differences between the observed-to-expected MRI fetal lung volume and observed-to-expected ultrasound lung-to-head ratio for the prediction of survival, the need for ECMO therapy, and the development of CLD in fetuses with left-sided CDH (p ≤ 0.0444), with the highest prognostic accuracy for survival (AUC = 0.863). Observed-to-expected MRI fetal lung volume and observed-to-expected ultrasound lung-to-head ratio correlated statistically significantly (p < 0.0001) for left-sided CDH with correlation coefficients (r) of 0.71, 0.71, and 0.56 for early, intermediate, and late times of gestation, respectively. The correlation was not statistically significant at any time for right-sided CDH (p ≥ 0.3947; r ≤ 0.26). CONCLUSION Observed-to-expected MRI fetal lung volume and observed-to-expected ultrasound lung-to-head ratio are valuable prognostic parameters for prenatal prediction of survival, the need for ECMO therapy, and the development of CLD in fetuses with left-sided CDH at all times of gestation. Observed-to-expected MRI fetal lung volume and observed-to-expected ultrasound lung-to-head ratio correlate statistically significantly for left-sided CDH, and the correlation is best before 32 weeks' gestation, but they do not correlate statistically significantly for right-sided CDH.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH), is an uncommon but severe condition in which there is a developmental defect in the fetal diaphragm, resulting in liver and bowel migrating to the chest cavity and impairing lung development and function for the neonate. This condition can be diagnosed during pregnancy and as such, is potentially amenable to in-utero prenatal intervention. Neonatal surgical repair is possible, but even with early surgical repair and improving neonatal management, neonatal morbidity and mortality is high. Prenatal interventions described to date have included maternal antenatal corticosteroid administration and fetal tracheal occlusion, with both methods aiming to improve lung growth and maturity. However surgical procedures have potential maternal complications, as the uterus and amniotic sac are breached in order to gain access to the fetus. OBJECTIVES To compare the effects of prenatal versus postnatal interventions for CDH on perinatal mortality and morbidity, longer-term infant outcomes and maternal morbidity, and to compare the effects of different prenatal interventions with each other. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2015) and reference lists of retrieved studies. SELECTION CRITERIA All published (including those published in abstract form), unpublished, and ongoing randomised controlled trials comparing prenatal and postnatal interventions for fetuses with CDH. Quasi-RCTs were eligible for inclusion but none were identified. Trials using a cross-over design are not eligible for inclusion. DATA COLLECTION AND ANALYSIS Two review authors evaluated trials for inclusion and methodological quality without consideration of their results according to the stated eligibility criteria and extracted data independently. Data were checked for accuracy. MAIN RESULTS We identified 11 studies for potential inclusion. Of those, we included three studies involving 97 women. Two additional studies are ongoing.Two trials examined in-utero fetal tracheal occlusion with standard (postnatal) care in fetuses with severe diaphragmatic hernia. Whilst the trials utilised fetal interventions that were similar, there were important differences in how access was gained to the fetus and in the timing and mode of delivery. Therefore, we did not combine these trials in meta-analysis and the results are examined in separate comparisons. One trial examined the effect of antenatal corticosteroids versus placebo. Overall, the methodological quality of the trials was variable and no data were available for a number of this review's secondary outcomes. In-utero fetal occlusion by maternal laparotomy versus standard postnatal management (one trial, 24 women)For the primary infant outcome (perinatal mortality), there were no data suitable for inclusion in the analysis. There was no difference between groups in terms of long-term infant survival (risk ratio (RR) 1.06, 95% confidence interval (CI) 0.66 to 1.69). In-utero fetal occlusion by minimally invasive fetoscopy versus standard postnatal management (one trial, 41 women)The primary infant outcome (perinatal mortality) was not reported. Minimally invasive fetoscopy was associated with a small reduction in the mean gestational age at birth (mean difference (MD) -1.80 weeks, 95% CI -3.13 to -0.47), but there was no clear difference in the risk of preterm birth before 37 weeks (RR 1.75, 95% CI 0.78 to 3.92). Long-term infant survival (three to six months) (RR 10.50, 95% CI 1.48 to 74.71) was increased with the intervention when compared with standard management, and there was a corresponding reduction in pulmonary hypertension (RR 0.58, 95% CI 0.36 to 0.93) associated with the intervention. There was no difference between groups in terms of preterm ruptured membranes (< 37 weeks) (RR 1.47, 95% CI 0.56 to 3.88) or maternal infectious morbidity (RR 3.14, 95% CI 0.14 to 72.92), and there were no maternal blood transfusions. Antenatal corticosteroids versus placebo (one trial, 32 women)We also included one trial (involving 32 women) examining the effect of antenatal corticosteroids versus placebo. There was no clear difference in the incidence of perinatal mortality (our primary infant outcome) between the group of women who received antenatal corticosteroids and the placebo control (RR 1.24, 95% CI 0.50 to 3.08). Data (mean only) were reported for two of our secondary outcomes (mechanical ventilation and days of hospital admission) but standard deviations (SDs) were not provided. For the purposes of this review and to permit further analysis we have estimated the SDs based on the reported P values reported in the trial report, although our estimation does assume that the SD is the same in both the intervention and control groups. There were no differences between the antenatal corticosteroid group and the placebo control in terms of days of mechanical ventilation (MD 18.00 days, 95% CI -14.77 to 50.77) or days of hospital admission (MD 17.00 days, 95% CI -13.93 to 47.93) . AUTHORS' CONCLUSIONS There is currently insufficient evidence to recommend in-utero intervention for fetuses with CDH as a part of routine clinical practice. We identified three small studies, with only one study adequately reporting on the primary outcome of this review - perinatal mortality, and there were few data pertaining to many of this review's secondary outcomes.WIth regard to the administration of antenatal corticosteroids, there remains a gap in current research, and a large multicentre trial with adequate statistical power should be undertaken to answer this unresolved question. More studies are needed to further examine the effect of in-utero fetal tracheal occlusion on important neonatal outcomes and long-term infant survival and health. Long-term follow-up is of particular importance, and should include morbidity and mortality measures. Further studies should examine the benefits of an in-utero intervention on subgroups with moderate and severe congenital diaphragmatic hernia. Indeed, there are three ongoing studies, being conducted by European, North and South American fetal medicine centres, which will contribute to this gap. Ongoing research and any implementation into clinical practice should include standardisation of the procedure, inclusion criteria and long-term childhood follow-up.

Abstract
Objectives: To compare outcomes in pregnancies with a prenatal detection of congenital diaphragmatic hernia (CDH) with children diagnosed after birth, treated at the same institution, and to determine the ability to predict prognosis through measurements of the observed to expected lung-to-head ratio (O/E LHR). Methods: This is a retrospective review of all children with CDH treated at our institution during 2006-2014. We compared outcomes of infants referred for surgery after postnatal diagnosis with outcomes of infants with prenatally diagnosed CDH. Results: In the prenatal group, O/E LHR was significantly different between survivors and deceased patients, with a cutoff at 35% O/E LHR. Survival to discharge and 1-year survival were significantly higher in the postnatal group that required intubation within 24 h; i.e., 92 and 89% versus 85 and 73% in the prenatal group (p < 0.05). There was less need for extracorporeal membrane oxygenation (ECMO), 41 versus 60%, and patch, 41 versus 75% (p < 0.001), in the postnatal group with early diagnosis compared with the prenatal group, respectively. Conclusion: Children with prenatally diagnosed CDH represent a population with a more severe condition compared to infants diagnosed after birth. They have poorer outcomes with higher needs for ECMO or use of patch, and lower survival rates were observed at an O/E LHR below 35%.

Abstract
AIM An estimated 140 pregnancies are diagnosed with congenital diaphragmatic hernia (CDH) in Australia and New Zealand each year, with these fetuses having a less than even chance of 1-year survival. Fetoscopic endoluminal tracheal occlusion (FETO) is a relatively new technique that offers a prenatal interventional strategy for selective cases of CDH. This is not routinely offered in Australia or New Zealand. The aim of this systematic review is to critically appraise controlled clinical trials investigating the role of FETO in moderate and severe isolated CDH and explore whether this treatment is justified within our region. METHODS A systematic literature search of multiple electronic databases was undertaken, with restrictions to human subjects and controlled clinical trials. RESULTS Nine relevant studies were identified. No current evidence was found in favour of FETO for moderate severity CDH. For severe CDH, the most recent evidence demonstrates significantly improved survival following FETO performed using contemporary percutaneous minimally invasive techniques. Optimum timing for balloon insertion, removal and occlusion duration remains conjectural. Substantial variation in survival rates observed among control groups highlights the impact of post-natal care in prenatally diagnosed CDH. CONCLUSION Until recently, evidence to support a role for FETO in prenatal CDH management was weak. Recently reported and ongoing controlled trials give cause for optimism, with improved FETO safety and increased survival reported for severe CDH cases. Should Australasia embrace FETO for selected CDH cases, a co-ordinated, evidence-informed service should be established under the guidance of experienced international partnerships.

Abstract
BACKGROUND Increased availability and usage of ultrasound screening have led to improved identification of fetal structural abnormalities prenatally. Few population-based studies have been published on prenatal detection for structural birth defects in the United States. The aim of this study is to determine the frequency of maternal reporting of abnormal prenatal ultrasounds for selected birth defects and to investigate associated maternal characteristics. METHODS Participants included 4013 mothers enrolled in the National Birth Defects Prevention Study who carried a fetus with at least one of 14 structural birth defects between 1997 and 2004. Frequencies of abnormal prenatal ultrasounds were based on maternal report and computed for isolated and multiple defects. Associations between maternal characteristics and abnormal prenatal ultrasounds were assessed using logistic regression. RESULTS Overall, 46% of participants reported an abnormal ultrasound. Infants with omphalocele, anencephaly, gastroschisis, and renal agenesis were more likely to have abnormal prenatal ultrasounds than those with cleft and limb abnormalities. Hispanic women were less likely to report abnormal prenatal ultrasounds of birth defects than Caucasians, as were women who had a body mass index ≥ 30 kg/m(2) compared with those with a normal body mass index. CONCLUSION Of the 14 selected birth defects in this study, less than half were reported by mothers of affected infants to have had an abnormal ultrasound during pregnancy. The frequency of reporting abnormal prenatal ultrasounds varies by type of defect, maternal race/ethnicity, and maternal body mass index status.

Abstract
OBJECTIVE To evaluate the effect of early fetoscopic tracheal occlusion (FETO) (22-24 weeks' gestation) on pulmonary response and neonatal survival in cases of extremely severe isolated congenital diaphragmatic hernia (CDH). METHODS This was a multicenter study involving fetuses with extremely severe CDH (lung-to-head ratio < 0.70, liver herniation into the thoracic cavity and no other detectable anomalies). Between August 2010 and December 2011, eight fetuses underwent early FETO. Data were compared with nine fetuses that underwent standard FETO and 10 without fetoscopic procedure from January 2006 to July 2010. FETO was performed under maternal epidural anesthesia, supplemented with fetal intramuscular anesthesia. Fetal lung size and vascularity were evaluated by ultrasound before and every 2 weeks after FETO. Postnatal therapy was equivalent for both treated fetuses and controls. Primary outcome was infant survival to 180 days and secondary outcome was fetal pulmonary response. RESULTS Maternal and fetal demographic characteristics and obstetric complications were similar in the three groups (P > 0.05). Infant survival rate was significantly higher in the early FETO group (62.5%) compared with the standard group (11.1%) and with controls (0%) (P < 0.01). Early FETO resulted in a significant improvement in fetal lung size and pulmonary vascularity when compared with standard FETO (P < 0.01). CONCLUSIONS Early FETO may improve infant survival by further increases of lung size and pulmonary vascularity in cases with extremely severe pulmonary hypoplasia in isolated CDH. This study supports formal testing of the hypothesis with a randomized controlled trial.

Abstract
Whereas structural fetal abnormalities are relatively frequent occurrences, many of these do not impact measurably on future life and/or are amenable to postnatal therapy. A small minority are considered to be potentially lethal or life-limiting. Examples include specific skeletal dysplasias, urinary tract abnormalities - typically those which lead to anhydramnios and pulmonary hypoplasia, some disorders of the central nervous system and trisomies 13 and 18. Without seeking to compile an exhaustive list of such conditions, we discuss the principles and new considerations in relation to antenatal diagnosis and perinatal management of such disorders.

Abstract
PURPOSE Publications aiming to prove the feasibility and safety of thoracoscopic CDH-repair in neonates grow in numbers. Some teams use selection criteria, but none have proven statistical evidence. The aim of this study is to detect risk factors for failure of thoracoscopic primary closure of CDH in neonates. METHODS In 8 centers performing minimal access surgery (MAS), complete prenatal, postnatal, and operative data were evaluated for a retrospective study concerning patients with thoracoscopic congenital diaphragmatic hernia (CDH) repair. Most of the selection criteria and risk factors mentioned in the literature were analyzed. Two groups were defined: Group A - neonates who tolerated thoracoscopic primary repair, and Group B - neonates who required conversion or presented with major complications after thoracoscopic repair. Univariate and multivariate logistic regressions were used to compare these two groups. RESULTS From 2006 to 2010, thoracoscopy was performed in 40 neonates: Group A consisting of 28 neonates, and Group B 9 patients. Three patients were excluded because of insufficient data or major associated malformations. Significant statistical differences were found in Group B for postnatal PaCO2 >60 mmHg, need of iNO during postnatal stabilization, intrathoracic position of the stomach, pulmonary hypertension signs on the postnatal cardiac ultrasound, and preoperative OI >3.0. On multivariate analysis, only an OI >3.0 was significantly associated with conversion or major post-operative complication of thoracoscopic primary repair. CONCLUSION CDH can be safely repaired in the neonatal period by thoracoscopy. The limiting factor for thoracoscopic CDH repair is PPHN. The best preoperative indicator for PPHN is OI. Prospective studies are nonetheless necessary to prove the effectiveness of using these risk factors as selection criteria to help design surgical management protocols for neonates presenting CDH.

Abstract
OBJECTIVE To investigate the prognostic value of a hernia sac in isolated congenital diaphragmatic hernia (CDH). METHODS Our database was searched to identify all consecutive cases of CDH referred to our fetal medicine unit between January 2004 and August 2011. Presence or absence of a hernia sac was assessed in liveborn cases using surgery or postnatal autopsy reports. We studied the correlation between the presence of a hernia sac and prenatal findings and perinatal morbidity and mortality. RESULTS Over the study period, there were 70 cases with isolated CDH born alive in which either a surgery or autopsy report was available. Neonatal death, either preoperative or postoperative, occurred in 1/18 (5.6%) infants with a hernia sac and in 17/52 (32.7%) cases without a hernia sac (P = 0.03). Patients with a hernia sac had a significantly higher observed to expected pulmonary volume on prenatal magnetic resonance imaging (51.9 vs 39.3%, P = 0.01). Neonatal morbidity in surviving infants was lower in the group with a hernia sac, although not significantly. CONCLUSION The presence of a hernia sac is associated with a higher pulmonary volume and a better overall prognosis for CDH.

Abstract
Congenital diaphragmatic hernia (CDH) is an anomaly that results in lung hypoplasia and pulmonary hypertension. The lungs of the CDH fetus have an abnormal architecture, with fewer bronchial branches and decreased number of arteries and veins, factors which result in pulmonary compromise postnatally. The goal of this review is to evaluate prenatal prognostic factors in the fetus with isolated left CDH, with particular emphasis on fetal MRI. These imaging indicators may be used to provide health professionals and the parents with the most accurate information about fetal prognosis.

Abstract
BACKGROUND Fetuses with severe congenital diaphragmatic hernia (CDH) and pulmonary hypoplasia may benefit from fetal endoluminal tracheal occlusion (FETO). Enlargement of the main bronchi and trachea appears to be a common complication of FETO. OBJECTIVE To retrospectively evaluate the trachea and main bronchi of infants who underwent FETO for CDH and compare diameters with age-matched references. MATERIAL AND METHODS Postnatal and follow-up chest radiographs were performed in seven children with unilateral CDH treated by FETO. Additional CT was performed in six of these (one neonate died before CT could be performed). Images were acquired from 3 days to 23 months of age. For each child, radiographs and CT images with optimal visualisation of the airways were selected for retrospective analysis. Tracheal and bronchial morphology was assessed by two experienced paediatric radiologists, and the diameters of these structures measured and compared with age-matched references. RESULTS Mean diameters of the trachea and main bronchi were above the age-matched normal range in all patients, regardless of the side of the hernia or the degree of lung hypoplasia. CONCLUSION Enlargement of the trachea and main bronchi appears following FETO and persists at least to the age of 5 years.

Abstract
Congenital Diaphragmatic Hernia (CDH) is defined by the presence of an orifice in the diaphragm, more often left and posterolateral that permits the herniation of abdominal contents into the thorax. The lungs are hypoplastic and have abnormal vessels that cause respiratory insufficiency and persistent pulmonary hypertension with high mortality. About one third of cases have cardiovascular malformations and lesser proportions have skeletal, neural, genitourinary, gastrointestinal or other defects. CDH can be a component of Pallister-Killian, Fryns, Ghersoni-Baruch, WAGR, Denys-Drash, Brachman-De Lange, Donnai-Barrow or Wolf-Hirschhorn syndromes. Some chromosomal anomalies involve CDH as well. The incidence is < 5 in 10,000 live-births. The etiology is unknown although clinical, genetic and experimental evidence points to disturbances in the retinoid-signaling pathway during organogenesis. Antenatal diagnosis is often made and this allows prenatal management (open correction of the hernia in the past and reversible fetoscopic tracheal obstruction nowadays) that may be indicated in cases with severe lung hypoplasia and grim prognosis. Treatment after birth requires all the refinements of critical care including extracorporeal membrane oxygenation prior to surgical correction. The best hospital series report 80% survival but it remains around 50% in population-based studies. Chronic respiratory tract disease, neurodevelopmental problems, neurosensorial hearing loss and gastroesophageal reflux are common problems in survivors. Much more research on several aspects of this severe condition is warranted.

Abstract
Mid-trimester, preterm prelabour rupture of the membranes (PPROM) with prolonged oligohydramnios remains a challenge for both obstetricians and neonatologists. Although survival rates have improved, morbidity remains common particularly due to pulmonary insufficiency and pulmonary hypertension. The aetiology of abnormal lung development is unknown but may depend critically on pulmonary vascular development. Antenatal evaluation of at-risk foetuses by three-dimensional ultrasound and MRI is possible but the techniques need to be further assessed. Antenatal corticosteroids given in cases of PPROM reduce the incidence of neonatal death, respiratory distress syndrome, intraventricular haemorrhage and necrotising enterocolitis without increasing maternal or neonatal infection. The true risk-benefit ratio of antibiotics, tocolysis and strategies to normalise amniotic fluid volume remains less clear. There is no consensus regarding the optimal ventilation strategy to support infants with pulmonary insufficiency following PPROM, and further work is required to determine whether and which pulmonary vasodilators improve long-term outcome in these infants.

Abstract
OBJECTIVES To evaluate the accuracy and probabilities of different fetal ultrasound parameters to predict neonatal outcome in isolated congenital diaphragmatic hernia (CDH). METHODS Between January 2004 and December 2010, we evaluated prospectively 108 fetuses with isolated CDH (82 left-sided and 26 right-sided). The following parameters were evaluated: gestational age at diagnosis, side of the diaphragmatic defect, presence of polyhydramnios, presence of liver herniated into the fetal thorax (liver-up), lung-to-head ratio (LHR) and observed/expected LHR (o/e-LHR), observed/expected contralateral and total fetal lung volume (o/e-ContFLV and o/e-TotFLV) ratios, ultrasonographic fetal lung volume/fetal weight ratio (US-FLW), observed/expected contralateral and main pulmonary artery diameter (o/e-ContPA and o/e-MPA) ratios and the contralateral vascularization index (Cont-VI). The outcomes were neonatal death and severe postnatal pulmonary arterial hypertension (PAH). RESULTS Neonatal mortality was 64.8% (70/108). Severe PAH was diagnosed in 68 (63.0%) cases, of which 63 died neonatally (92.6%) (P < 0.001). Gestational age at diagnosis, side of the defect and polyhydramnios were not associated with poor outcome (P > 0.05). LHR, o/e-LHR, liver-up, o/e-ContFLV, o/e-TotFLV, US-FLW, o/e-ContPA, o/e-MPA and Cont-VI were associated with both neonatal death and severe postnatal PAH (P < 0.001). Receiver-operating characteristics curves indicated that measuring total lung volumes (o/e-TotFLV and US-FLW) was more accurate than was considering only the contralateral lung sizes (LHR, o/e-LHR and o/e-ContFLV; P < 0.05), and Cont-VI was the most accurate ultrasound parameter to predict neonatal death and severe PAH (P < 0.001). CONCLUSIONS Evaluating total lung volumes is more accurate than is measuring only the contralateral lung size. Evaluating pulmonary vascularization (Cont-VI) is the most accurate predictor of neonatal outcome. Estimating the probability of survival and severe PAH allows classification of cases according to prognosis.

Correlation between US and MRI for prenatal lung volumetry in diaphragmatic hernia, and use of Doppler to identify the ipsilateral lung cap. Pediatr Radiol 2011; 41:1569-77. [PMID: 21938506 DOI: 10.1007/s00247-011-2200-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2010] [Revised: 03/28/2011] [Accepted: 05/16/2011] [Indexed: 11/27/2022]
Abstract
BACKGROUND Pulmonary hypoplasia is a common cause of neonatal death. OBJECTIVE To describe the correlation between relative fetal lung volume (RFLV) and lung-to-head ratio (LHR) in fetuses with unilateral diaphragmatic hernia. Additionally, to describe identification of the ipsilateral lung cap by power Doppler. MATERIALS AND METHODS Single-institution study of consecutive fetuses with diaphragmatic hernia. LHR (by US) and RFLV (by MRI) were correlated in fetuses with and without an ipsilateral lung cap seen at MRI. In four, color/power Doppler was used to follow the pulmonary artery of the ipsilateral lung to identify the compressed cap. RESULTS The study included 48 fetuses of 20-38 weeks' gestational age (mean, 26 weeks). Mean LHR was 1.52 (range, 0.6-3) in fetuses with a lung cap and 1.15 (range, 0.6-2.58) in fetuses without (P = 0.043). Mean RFLV was 47.4% (range, 18-80%) in fetuses with and 32.9% (range, 14-57%) in fetuses without a lung cap (P = 0.005). RFLV and LHR correlated (r = 0.41, P = 0.01 in those with a cap; r = 0.50, P = 0.05 in those without). Power Doppler identified the ipsilateral lung cap and pulsed Doppler confirmed pulmonary vascularization in four of four fetuses. CONCLUSION LHR underestimates lung volume in fetuses with an ipsilateral lung cap. Power Doppler may be useful for identifying the cap.

Abstract
OBJECTIVE We sought to develop a gestational age-independent sonographic parameter to characterize lung growth. STUDY DESIGN Reported descriptors of lung growth, including lung-to-head circumference (HC) ratio (LHR) and observed/expected LHR, were examined. A new index, the quantitative lung index (QLI) was derived using published data on HC and the area of the base of the right lung. RESULTS Neither the LHR nor the observed/expected LHR proved to be gestational age independent. Right lung growth can be expressed using the following formula: QLI = lung area/(HC/10)^2. The 50th percentile of the QLI remained constant at approximately 1.0 for the gestational age between 16-32 weeks. A small lung (<1st percentile) was defined as a QLI <0.6. CONCLUSION Fetal right lung growth can be adequately described using the QLI, independent of gestational age. Further studies are needed to assess the clinical accuracy of the QLI in characterizing fetal right lung growth.

Abstract
OBJECTIVES To predict neonatal survival and pulmonary hypertension by measurement of fetal pulmonary artery reactivity to maternal hyperoxygenation in fetuses with severe congenital diaphragmatic hernia treated by fetoscopic endoluminal tracheal occlusion (FETO). METHODS Thirty-eight fetuses underwent FETO at around 28 weeks' gestation and the balloon was removed at 34 weeks in most cases. We performed a hyperoxygenation test and measured the lung-to-head ratio of each fetus before and after each procedure. Outcome measures were neonatal survival, occurrence of pulmonary hypertension and its response to inhaled nitric oxide (iNO). RESULTS Fetuses that survived had a larger increase in lung size and decrease of resistance in the first branch of the main pulmonary artery than did those that died. Both measures were also predictive of pulmonary hypertension unresponsive to iNO. The hyperoxygenation test and lung-to-head ratio were both best predictive for neonatal survival when measured following removal of the balloon (P < 0.002). Discriminant analysis confirmed that these two parameters are independent predictors of outcome. CONCLUSIONS In fetuses undergoing FETO, pulmonary vascular reactivity in relation to oxygen and lung size are independent predictors of neonatal survival and pulmonary hypertension. The hyperoxygenation test merits further study in expectantly managed cases.

Tracheomegaly: a complication of fetal endoscopic tracheal occlusion in the treatment of congenital diaphragmatic hernia. Pediatr Radiol 2010; 40:674-80.

Abstract
BACKGROUND Fetal endoscopic tracheal occlusion (FETO) is a promising treatment for severe congenital diaphragmatic hernia, a condition that carries significant morbidity and mortality. It is hypothesised that balloon occlusion of the fetal trachea leads to an improvement in lung growth and development. The major documented complications of FETO to date are related to preterm delivery. OBJECTIVE To report a series of five infants who developed tracheomegaly following FETO. MATERIALS AND METHODS Review of all children referred with tracheomegaly to the paediatric intensive care and tracheal service at two referral centres. RESULTS Five neonates presented with features of respiratory distress shortly after birth and were subsequently found to have marked tracheomegaly. Two neonates had tracheomalacia in addition. CONCLUSION There are no previous reports in the literature describing tracheomalacia, or more specifically, tracheomegaly, as a consequence of FETO. We propose that the particularly compliant fetal airway is at risk of mechanical damage from in utero balloon occlusion. This observation of a new problem in this cohort suggests a thorough evaluation of the trachea should be performed in children who have had FETO in utero. It may be that balloon occlusion of the trachea earlier in utero (before 26 weeks' gestation) predisposes to this condition.

Abstract
OBJECTIVE To characterize tracheal fluid flow during fetal breathing movements by Doppler ultrasound. STUDY DESIGN To use pulsed Doppler to measure flow velocity during inspiration and expiration in a cross-sectional study of 15 normal fetuses and determine the correlation, if any, between flow velocity and gestational age. RESULTS Cyclic respiratory profiles - both regular and irregular - were observed. Intratracheal flow velocity was very elevated during inspiration, ranging from 10 to 80 cm/s and from 5 to 20 cm/s during expiration. CONCLUSION This technique enables the noninvasive semiquantitative evaluation of fetal breathing movements. This Doppler application opens the field for future studies to characterize the extent of pulmonary hypoplasia.

Abstract
PURPOSE Tetrandrine (Tet) is a bisbenzylisoquinoline alkaloid isolated from the root of Stephania tetrandra, which has been used in traditional Chinese medicine to treat patients with silicosis, asthma, and pulmonary hypertension, and others and can be used as a pulmonary therapeutic agent. We hypothesized that it can also improve the lung growth in congenital diaphragmatic hernia (CDH) for its multiple biological effects. There are increasing evidences that suggest transforming growth factor beta1(TGF-beta1) plays a crucial role in fetal lung growth and morphogenesis. The aim of this study was to evaluate the effect of prenatal administration of Tet and to investigate its possible mechanism on the expression of TGF-beta1 in the lung of nitrofen-induced CDH rat model. METHODS A CDH model was induced in pregnant Sprague-Dawley rats by administration of nitrofen on day 9.5 of gestation (Ed9.5 term, day 22). Tetrandrine (30 mg/kg) was given through gavage (once a day, for 3 days) on Ed11.5. Accordingly, there were 3 groups as follows: control (n = 9), CDH (n = 9), and CDH + Tet (n = 9). All the fetuses were delivered by cesarean delivery on Ed16.5, 18.5, and 21.5, respectively, to check if diaphragmatic hernia existed on each fetus, then the lung tissue weight (LW) and body weight (BW) of each fetus were recorded. Histologic evaluations and TGF-beta1 immunohistochemistry staining in the lung sample were performed for image analysis. RESULTS Diaphragmatic hernia was observed in 95 of the 112 rat fetuses in CDH and CDH + Tet groups on Ed18.5 and Ed21.5 (84.8%), the incidence between the 2 groups had no statistical significance (P = .642). Lung weight/body weight in the CDH group and the CDH + Tet group were lower than that in the control group (P < .01), and LW/BW in the CDH group was lower than that in the CDH + Tet group (P < .05). Observed under the light microscope and electron microscope, marked hypoplasia of the lungs in fetuses among the CDH groups was observed, in contrast to improvement of the lungs in CDH + Tet fetuses. Statistical differences in morphological parameters (percentage of alveoli area, counting bronchus) were found even on Ed16.5 when diaphragm had not closed (P < .01). The number of type II pneumocytes and lamellar bodies in each group had no significant difference (P > .05). The immunoreactivity of TGF-beta1 in CDH group and CDH + Tet group were markedly stronger than that in the control group (P < .01). In addition, TGF-beta1 expression in the CDH group was stronger than that in the CDH + Tet group (P < .01). CONCLUSION Nitrofen can interfere with lung development early in the fetal rat development before and separate from diaphragm development, and increased expression of TGF-beta1 in the lung of CDH rat model may suppress lung growth and development. Prenatal treatment with Tet can improve the growth of the lung of the nitrofen-induced CDH fetuses and its mechanism seems to be involved in downregulating the expression of TGF-beta1. It is a likely new approach to treat CDH and its coexistent lung hypoplasia by maternal Tet administration.

Abstract
Pulmonary hypoplasia and persistent pulmonary hypertension are the most important reasons for the high morbidity and mortality of congenital diaphragmatic hernia (CDH). Despite surgical advances and advances in neonatal intensive care, the mortality still remains high. Then the research on how to improve prenatal fetal lung growth has become a focus. Some researches involved in fetal surgery, tracheal occlusion, prenatal use of corticosteroids etc., have been carried out in CDH animal models and humans. But the results either showed no benefit for the outcome of CDH or were unproved. Tetrandrine is a bisbenzylisoquinoline alkaloid isolated from the root of Stephania tetrandra. It has been used in traditional Chinese medicine for several decades to treat patients with silicosis, asthma and pulmonary hypertension etc. Some researches showed that prenatal tetrandrine administration can improve the lung development in CDH rat models. We hypothesize that prenatal treatment with tetrandrine can reverse the abnormal condition in the lung of newborn with CDH, and thus decrease the mortality.

Abstract
With increasing use of fetal ultrasound comes an increase in the detection of clinically silent 'abnormalities' which pose diagnostic and management dilemmas for perinatologists and paediatricians. Congenital thoracic malformations (CTMs) (excluding congenital diaphragmatic hernia) are one such example, where a few cases are symptomatic in early life and management options are clear, but the majority are clinically asymptomatic, giving rise to difficulties in defining postnatal management of the well child with a sonographic or radiological lesion. Here, we will outline the prenatal presentation and natural history of CTMs that are not congenital diaphragmatic herniae and briefly discuss the approach to postnatal management, which is covered in more detail in the review by Laje and Liechty in this issue.

Abstract
PURPOSE Fetal tracheal occlusion (TO) is offered to fetuses with severe pulmonary hypoplasia due to congenital diaphragmatic hernia (CDH). TO induces lung growth, but even when performed minimally invasive, there is a risk for iatrogenic preterm delivery. Whenever this is anticipated, maternal glucocorticoids (GC) may be given to enhance lung maturation. The pulmonary effects of GC in fetuses with CDH that underwent TO are yet poorly defined. Therefore, we conducted a placebo-controlled study in the nitrofen (NF) rat model for CDH. METHODS Pregnant rats were gavage fed NF or olive oil (OO) on ED9.5. At ED19.0, fetuses were either assigned to TO or left untouched. Maternal betamethasone (BM) or saline (PLAC) was administered on ED20. Necropsy was done on ED21.5 to obtain lung-to-body-weight ratio (LBWR), and perform quantitative RT-PCR and fluorescent immunostaining for Ki-67 and proliferating cell nuclear antigen (PCNA) in fetal lungs. RESULTS CDH fetuses had a lower LBWR than normal fetuses, but comparable pulmonary PCNA and Ki-67 expression levels. TO increased LBWR, irrespective of maternal BM or PLAC. However, BM but not PLAC inhibited proliferation in TO and unoperated fetuses. CONCLUSION Rats with NF-induced CDH have hypoplastic lungs with normal proliferation indices. TO triggers proliferation, an effect countered by BM.
