Objectives. To assess the effectiveness of the use of prenatal ultrasound indexes in congenital diaphragmatic hernia of the fetus to determine the postnatal prognosis. Materials. The analysis of 95 observations of left-sided congenital diaphragmatic hernia of the fetus was carried out. In the prenatal period, the composition of organs displaced into the pleural cavity was determined, the heart compression index (HCI), O/E LHR according to Jani and DeKoninck, and QLI were calculated. Results. Survival rate of newborns was 57.9%, mortality rate was 42.1%. The newborns were divided into two groups depending on the outcome of the disease. Group I — surviving newborns (n = 55), group II — deceased patients (n = 40). In the analyzed groups, there were no statistical differences in the timing of delivery, birth weight of newborns, the severity of asphyxia after birth and the type of hernia. In group I, the intestinal loops and stomach were significantly more often identified in the pleural cavity in isolation, less often the liver. HCI corresponded to 1.3, Jani O/E LHR 45.7%, DeKoninck O/E LHR 38.7%, QLI 0.7. In group II, concomitant malformations, polyhydramnios and displacement of the liver into the pleural cavity were significantly more frequent. HCI was 1.5, Jani O/E LHR 38.6%, DeKoninck O/E LHR 32.0%, QLI 0.6. Conclusions. In predicting the outcome of the disease for a newborn, the most effective is a comprehensive assessment of the location of the liver, the heart compression index and the index of lung hypoplasia (O/E LHR according to Jani). The diagnostic accuracy of the method is 80%, the sensitivity is 74.4%, and the specificity is 83.3%.

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.

Prenatal Intervention

The central tendon defect type of congenital diaphragmatic hernia (CDH) is extremely rare and usually associated with a significant pericardial effusion. Prenatal diagnostic ultrasound features of this quite rare entity remain often overlooked or misdiagnosed. There is a dearth of literature about the role of prenatal intervention, often through an elective pericardiocentesis, for the prevention of lung hypoplasia and to decrease the overall neonatal morbidity and mortality. To the best of our knowledge, till date, there is only one case that was subjected to a prenatal intervention. Here, we present a second case of a central tendon defect type of CDH with a large pericardial effusion that was subjected to a prenatal transthoracic pericardiocentesis. Although smooth intubation and ventilation were performed immediately after birth, the infant suffered for several months from respiratory instability. Laparoscopic central tendon hernia repair was performed, and neonate was discharged home at seven months of age. Although prenatal pericardiocentesis may facilitate smoother postnatal intubation and ventilation, its broader effect on respiratory function is uncertain and still remains elusive.

Congenital diaphragmatic hernia (CDH) is a structural birth defect characterized by a diaphragmatic defect, lung hypoplasia and structural vascular defects. In spite of recent developments, the pathogenesis of CDH is still poorly understood. CDH is a complex congenital disorder with multifactorial etiology consisting of genetic, cellular and mechanical factors. This review explores the cellular origin of CDH pathogenesis in the diaphragm and lungs and describes recent developments in basic and translational CDH research.

AbstractCongenital diaphragmatic hernia is a life-threatening condition frequently associated with various congenital cardiac diseases. In congenital diaphragmatic hernia associated with tetralogy of Fallot, central pulmonary artery size of the affected side may not reflect the capacitance of peripheral pulmonary vascular beds. We report a case of congenital diaphragmatic hernia associated with tetralogy of Fallot, which was repaired after assessing the adequacy of the pulmonary vascular beds by intra-operative pulmonary blood flow study.

Abstract Introduction We aimed to establish and validate a risk score for fetuses with congenital diaphragmatic hernia (CDH) using only prenatal ultrasound findings. Material and Methods Derivation (2011–2016, n = 350) and validation (2006–2010, n = 270) cohorts were obtained from a Japanese CDH study group database. Using a logistic regression analysis, we created a prediction model and weighted scoring system from the derivation dataset and calculated the odds ratio of an unsatisfactory prognosis (death within 90 days of life or hospitalization duration exceeding 180 days). Five adverse prognostic factors obtained using prenatal ultrasound, including an observed/expected lung area-to-head circumference ratio (o/eLHR) <25%, liver herniation occupying more than one-third of the thoracic space, thoracic stomach, right-side CDH, and severe malformations, were used as predictors. The obtained model was validated using the validation cohort. Results The unsatisfactory prognosis prediction model was obtained based on the adjusted odds ratios. The C statistics of the model were 0.83 and 0.80 in the derivation and validation datasets, respectively. The five variables were weighted proportionally to their adjusted odds ratios for an unsatisfactory prognosis (o/eLHR <25%, 1 point; liver herniation occupying more than one-third of the thoracic space, 1 point; thoracic stomach, 1 point; right-side CDH, 2 points; and severe malformations, 3 points). Unsatisfactory prognosis rates for the low- (0–2 points), intermediate- (3–5 points), and high-risk (6–8 points) groups were 17, 46, and 100%, respectively (p < 0.001), in the validation cohort. Conclusion Our simple risk score effectively predicted the prognosis of fetuses with CDH.

Medical Stabilization

Congenital diaphragmatic hernia is an embryologic defect in diaphragm formation that allows abdominal contents to enter into the fetal pleural cavity, resulting in ipsilateral lung compression, pulmonary hypoplasia, and abnormal pulmonary vasculature. Though diagnosis is frequently made on prenatal imaging, the diagnosis should be considered in any newborn with respiratory distress. Prenatal predictors of defect severity include evaluation of observed-to-expected lung volumes on fetal magnetic resonance imaging and lung-to-head ratio on fetal ultrasound. Treatment focuses on medical stabilization, including optimization of oxygenation and ventilation, followed by surgical repair. Anesthetic considerations for these patients include management of coexisting cardiac disease and ventilatory parameters, in addition to standard neonatal anesthetic considerations.
