Abstract
Fetal therapy term has been described for any therapeutic intervention either invasive or noninvasive for the purpose of correcting or treating any fetal malformation or condition. Fetal therapy is a rapidly evolving specialty and has gained pace in last two decades and now fetal intervention is being tried in many malformations with rate of success varying with the type of different fetal conditions. The advances in imaging techniques have allowed fetal medicine persons to make earlier and accurate diagnosis of numerous fetal anomalies. Still many fetal anomalies are managed postnatally because the fetal outcomes have not changed significantly with the use of fetal therapy and this approach avoids unnecessary maternal risk secondary to inutero intervention. The short-term maternal risk associated with fetal surgery includes preterm labor, premature rupture of membranes, uterine wall bleeding, chorioamniotic separation, placental abruption, chorioamnionitis, and anesthesia risk. Whereas, maternal long-term complications include risk of infertility, uterine rupture, and need for cesarean section in future pregnancies. The decision for invasive fetal therapy should be taken after discussion with parents about the various aspects like postnatal fetal outcome without fetal intervention, possible outcome if the fetal intervention is done, available postnatal intervention for the fetal condition, and possible short-term and long-term maternal complications. The center where fetal intervention is done should have facility of multi-disciplinary team to manage both maternal and fetal complications. The major issues in the development of fetal surgery include selection of patient for intervention, crafting effective fetal surgical skills, requirement of regular fetal and uterine monitoring, effective tocolysis, and minimizing fetal and maternal fetal risks. This review will cover the surgical or invasive aspect of fetal therapy with available evidence and will highlight the progress made in the management of fetal malformations in last two decades.

Postnatally diagnosed coexisting congenital diaphragmatic hernia with pulmonary sequestration: a report of two cases. Obstet Gynecol Sci 2020; 63:529-533. [PMID: 32689778 PMCID: PMC7393745 DOI: 10.5468/ogs.20052] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Accepted: 05/05/2020] [Indexed: 11/08/2022] Open
Abstract
While the associations between pulmonary sequestration (PS) and congenital diaphragmatic hernia (CDH) are known, CDH may be obscured by PS and thus, overlooked on prenatal ultrasonography when coexisting with PS. We present 2 cases of postnatally diagnosed CDH combined with PS. In both cases, PS was prenatally diagnosed as an isolated lung mass, while CDH was confirmed only after birth. Both newborns were sufficiently stable that management was not required immediately after birth. PS may function as an "anatomical barrier" to prevent herniation of the abdominal contents into the chest, thus acting as a "protector" providing normal lung maturation throughout pregnancy. If PS is suspected prenatally, coexisting CDH may be obscured; thus, close prenatal care and counseling of the parents regarding the possibility of CDH are essential. These infants should be delivered at a tertiary center, and imaging should be performed to exclude coexisting CDH.

Abstract
AIM To describe perinatal outcomes of fetuses with a prenatal diagnosis of a concomitant lung lesion in the setting of congenital diaphragmatic hernia (CDH) and to compare outcomes with an isolated CDH control group without a lung lesion, matched by ultrasound-based prognostic markers including presence of liver herniation and lung measurements. MATERIAL AND METHODS This was a retrospective case-control study, wherein all pregnancies diagnosed with CDH and concomitant lung lesions were identified between July 1, 2008, and December 31, 2018. For each case, 2 controls with isolated CDH from the same study period were selected after matching for the presence of liver herniation into the thoracic cavity and ultrasound-based lung measurements either observed over expected lung-to-head ratio (LHR) or absolute LHR with their corresponding gestational age. The outcomes analyzed in the 2 groups included survival to hospital discharge, neonatal intensive care unit (NICU) length of stay (LOS), extracorporeal membrane oxygenation (ECMO) requirement and need for supplemental oxygen (O2) at day 30 of life. RESULTS A total of 21 pregnancies were identified with CDH and a concomitant lung lesion in the study period. All the lung lesions were stratified into a "low-risk category" with a congenital cystic adenomatoid malformation volume ratio of less than 1.0 at the time of presentation. None of these fetuses developed hydrops or required in utero intervention. Overall survival in the group was 80.7% (17/21) and rate of ECMO was 38.1%. Causes of mortality included pulmonary insufficiency, sepsis, renal failure, and bowel infarction. Upon comparison between the cases and controls, the 2 groups were similar with respect to pregnancy demographics. There were no fetal demises in either group. Outcomes including survival rate, NICU LOS, ECMO requirements and need for supplemental O2 at day 30 of life, were comparable among the 2 groups. CONCLUSIONS In our descriptive series, the presence of a concomitant, low-risk lung lesion in the setting of fetal CDH did not have a significant impact on the natural course of the disease, nor was it associated with a worse prognosis.

Abstract
OBJECTIVES To assess the ability of prenatal ultrasound (US) in identifying systemic feeding arteries in bronchopulmonary sequestrations and hybrid lesions and report the ability of US in classifying bronchopulmonary sequestrations as intralobar or extralobar. METHODS Institutional Review Board-approved radiology and clinical database searches from 2008 to 2015 were performed for prenatal lung lesions with final diagnoses of bronchopulmonary sequestrations or hybrid lesions. All patients had detailed US examinations, and most patients had ultrafast magnetic resonance imaging (MRI). Lesion location, size, and identification of systemic feeding arteries and draining veins were assessed with US. RESULTS The study consisted of 102 bronchopulmonary sequestrations and 86 hybrid lesions. The median maternal age was 30 years. The median gestational age was 22 weeks 5 days. Of bronchopulmonary sequestrations, 66 had surgical pathologic confirmation, and 100 had postnatal imaging. Bronchopulmonary sequestration locations were intrathoracic (n = 77), intra-abdominal (n = 19), and transdiaphragmatic (n = 6). Of hybrid lesions, 84 had surgical pathologic confirmation, and 83 had postnatal imaging. Hybrid lesion locations were intrathoracic (n = 84) and transdiaphragmatic (n = 2). Ultrasound correctly identified systemic feeding arteries in 86 of 102 bronchopulmonary sequestrations and 79 of 86 hybrid lesions. Of patients who underwent MRI, systemic feeding arteries were reported in 62 of 92 bronchopulmonary sequestrations and 56 of 81 hybrid lesions. Ultrasound identified more systemic feeding arteries than MRI in both bronchopulmonary sequestrations and hybrid lesions (P < .01). Magnetic resonance imaging identified systemic feeding arteries that US did not in only 2 cases. In cases in which both systemic feeding arteries and draining veins were identified, US could correctly predict intrathoracic lesions as intralobar or extralobar in 44 of 49 bronchopulmonary sequestrations and 68 of 73 hybrid lesions. CONCLUSIONS Ultrasound is most accurate for systemic feeding artery detection in bronchopulmonary sequestrations and hybrid lesions and can also type the lesions as intralobar or extralobar when draining veins are evaluated.

Abstract
We report the case of a neonate affected by prenatally diagnosed congenital diaphragmatic hernia (CDH), treated by thoracoscopy. During the procedure, we detected an associated extralobar pulmonary sequestration (EPS), which was preoperatively undiagnosed, and we removed it. EPS has been shown to be associated with CDH in up to 15 to 40% of cases. A possible explanation hypothesized is that pulmonary sequestration, which develops at 4 to 5 weeks of gestation, can disturb the fusion of the diaphragm and closure of the pleuroperitoneal canal. The thoracoscopic approach permitted us to identify the thoracic EPS that probably would have been otherwise missed.

Abstract
We describe two cases of postnatally diagnosed congenital diaphragmatic hernia (CDH) combined with pulmonary sequestration, both of which were diagnosed as isolated pulmonary sequestration on prenatal ultrasound. In these cases, prenatal ultrasonography demonstrated only a hyperechoic mass on the left lower lung and the diaphragm seemed intact. In each case both lungs showed otherwise normal development throughout pregnancy. Pulmonary sequestration may serve as a 'protector', preventing herniation of abdominal contents into the thoracic cavity. The co-occurrence of CDH may be obscured by a lung mass, especially on the left lower lung, and therefore it is necessary to deliver these infants at a tertiary center and parents should be counseled about the possibility of postnatal CDH.

Abstract
Congenital cystic lung disease comprises a broad spectrum of rare but clinically significant developmental abnormalities, including congenital pulmonary adenomatoid malformations, bronchopulmonary sequestrations, bronchogenic cysts, and congenital lobar emphysema that result from perturbations in lung and airway embryogenesis. As congenital lung lesions are now more commonly recognized antenatally, mothers require accurate prenatal counseling and appropriate perinatal management. In light of long-term complications of infection and malignancy, there is growing consensus that infants with asymptomatic lesions should undergo elective excision of congenital pulmonary adenomatoid malformation (CPAM) or bronchopulmonary sequestration (BPS). This review will focus on advancements and current practice in the diagnosis and management of CPAM and BPS, identifying aspects of the literature that are confusing or controversial. Although our knowledge and pre- and postnatal management of lung lesions will continue to evolve and improve, there is a compelling need for a unified clinical and pathological classification system that creates a common platform for discussion, clinical management, and research.

Abstract
OBJECTIVE Evaluate the advantages of color Doppler and pulsed Doppler in the diagnosis and prognosis of fetal pulmonary malformations. MATERIALS AND METHOD This retrospective study of 24 fetuses explored pulmonary malformations using sonography. A classification into four groups was made based on the presence of cysts and the echogenicity of the lesion, then analysis of video recordings including Doppler with an interpretation chart: afferent vessel, color chart, spectrum shape (afferent vessel and within the malformation) to determine the contribution of Doppler within each group. RESULTS Four lesions were avascular: bronchogenic cysts (three cases), subphrenic sequestration (one case). The other lesions were vascularized and color Doppler determined the source of vascularization feeding the malformation: branches of the pulmonary artery in 13 cases (eight cases of cystic adenomatoid disease, two cases of atresia, and three airway obstacles) or the aorta in seven cases (pulmonary sequestrations) with pulmonary venous return, six cases (intralobular sequestrations), or systemic venous return, one case (extralobular sequestration). The pulsed Doppler recording in the malformation (six cases) completed the color Doppler examination by showing the different spectrum shapes according to the aortic or pulmonary source of flow. The color chart matched in three cases (normal pulmonary segmentation) and was heterogeneous in eight cases (parenchymatous dysplasia). Furthermore, perfusion intensity was correlated with lesion progression. CONCLUSION Color Doppler and pulsed Doppler provided a more precise diagnosis of these malformations and seems to contribute prognostic information.

Abstract
Antenatal diagnosis of lung abnormalities by ultrasound has been a much more frequent occurrence in recent years. There is a range of appearances from uniform increased echogenicity through to lesions containing large echo-free areas. Bilateral uniformly increased echogenicity has a poor outlook but in all other situations outcome cannot be accurately predicted from an early second trimester scan. Follow-up through pregnancy often allows a fairly accurate prognosis to be made but the appearance of the lesion does not accurately predict histology. A conservative approach to the antenatal management of unilateral lesions is recommended with long-term postnatal follow-up for all lesions because of the unknown long-term outcome for the lesions, many of which are symptomatic postnatally.

Abstract
The bronchopulmonary-foregut malformations (BPFM) are usually sporadic, solitary cystic hamartomas involving conducting airways, arteries, venous drainage, and lung parenchyma. Transitional, compound hamartomas exist, and only their morphology is well-known. Between 1984-1994 we encountered and studied 10 unrelated patients and a stillborn infant with BPFM (out of 24,000 families). Ten were diagnosed in utero and one at birth as having congenital cystic adenomatoid malformation of the lung (CCAML). Postnatally, two diagnoses (20%) were corrected to bronchogenic cyst (BC) and diaphragmatic hernia, respectively. Bilateral lung involvement was present in 1 patient, and in 2 there was a considerable macroscopic regression of the hamartoma. Histologic studies of the six resected CCAML confirmed the diagnosis and implied dysregulated paracrine growth with its cellular and extracellular growth factors, protooncogenes, oncogenes, cytokines, cell-adhesive molecules, and receptors of these regulatory peptides, and their complex interactions as developmental morphogens in time and space.
