Abstract
BACKGROUND Open fetal resection for large lung lesions has virtually been replaced by maternal steroid administration. Despite this paradigm shift, little is known about the effects steroids have on lung lesion growth in utero. METHODS A 10-year retrospective review of all prenatally diagnosed lung lesions cared for at our fetal care center was performed. We evaluated the effects of prenatal steroids on congenital pulmonary airway malformation (CPAM)-volume-ratio (CVR), distinguishing change in CVR among CPAMs, bronchopulmonary sequestrations (BPS), and bronchial atresias. We also correlated fetal ultrasound and MRI findings with pathology to determine the accuracy of prenatal diagnosis. RESULTS We evaluated 199 fetuses with a prenatal lung lesion. Fifty-four (27 %) were treated with prenatal steroids with a subsequent 21 % mean reduction in the CVR (2.1 ± 1.4 to 1.1 ± 0.4, p = 0.003). Fetuses with hydrops and mediastinal shift who were treated with steroids rarely had resolution of these radiographic findings. Postnatal pathology was available for 91/199 patients (45.7 %). The most common diagnosis was CPAM (42/91, 46 %), followed by BPS (30/91, 33 %), and bronchial atresia (14/91, 15 %). Fetuses who received steroids and had pathology consistent with CPAM were more likely to have a reduction in their CVR (p = 0.02). Fetal ultrasound correctly diagnosed the type of lung lesion in 75 % of cases and fetal MRI in 81 % of cases. CONCLUSIONS Prenatally diagnosed CPAMs are more likely to respond to maternal steroids than BPS or bronchial atresias. Knowing the diagnosis in utero could aid to steward steroid usage, however, fetal imagining modalities are not perfect in distinguishing subtype. LEVEL OF EVIDENCE III.

Abstract
OBJECTIVES We have previously described gestational-age-independent sonographic indices to assess fetal lung size in the right and left lungs: The Quantitative Lung Index for the right lung (QLI-R) and for the left lung (QLI-L), respectively. The purpose of this study was to evaluate the clinical cutoff point of the QLI-R to predict pulmonary hypoplasia and neonatal death. MATERIALS AND METHODS Retrospective assessment of the QLI-R in patients with left-sided congenital diaphragmatic hernia (CDH-L) and other fetal conditions at risk for fetal pulmonary hypoplasia. Cross-section and longitudinal assessment of the behavior of the QLI-R in untreated and treated patients. ROC curve analysis to determine the optimal cutoff point of the QLI-R in predicting neonatal death. RESULTS One hundred eighteen patients with CDH-L and other fetal conditions at risk for pulmonary hypoplasia had QLI-R measurements done. Seventeen patients were excluded for various reasons. Eleven patients with conditions other than CDH-L but at risk for pulmonary hypoplasia were used for intraclass coefficient measurements of the QLI-R. Ninety patients had CDH-L, of which 78 did not undergo antenatal intervention and in which the cutoff point for pulmonary hypoplasia and neonatal demise was assessed. Stent tracheal occlusion was performed in the remaining 12 patients with CDH-L, in which the behavior of the QLI after surgery was assessed. Analysis of the ICC showed an overall intra-rater reliability of 0.985 (Cronbach's Alpha-based). There was no correlation between gestational age and QLI-R (-0.73, Pearson correlation, p = .72). Twenty-six of the 78 patients (33%) with CDH-L managed expectantly had a neonatal demise. A QLI-R equal to or less than 0.45 was significantly predictive of neonatal demise (area under the curve 0.64, p = .046, sensitivity 77%). Nine of the 12 patients (75%) that underwent tracheal occlusion had neonatal survival. Of these, 10 had serial assessments of the QLI-R after surgery. An increase in the QLI-R of 0.11 was associated with a tendency for neonatal survival (p = .056). CONCLUSION Our study confirms that the QLI-R is a gestational-age-independent measurement of fetal lung size, with a high degree of reproducibility. In a population of expectantly managed CDH-L patients, a cutoff value of the QLI-R of 0.45 or lower is predictive of neonatal death from pulmonary hypoplasia. The QLI-R can be used to monitor fetal lung growth after tracheal occlusion, and an increase in the QLI-R is suggestive of neonatal survival. Further prospective studies are needed to confirm these findings and to explore the use of the QLI in other populations at risk for pulmonary hypoplasia and consequent neonatal demise.

Lifesaving Treatments for the Tiniest Patients-A Narrative Description of Old and New Minimally Invasive Approaches in the Arena of Fetal Surgery. CHILDREN (BASEL, SWITZERLAND) 2022; 10:children10010067. [PMID: 36670618 PMCID: PMC9856479 DOI: 10.3390/children10010067] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 12/14/2022] [Accepted: 12/21/2022] [Indexed: 12/31/2022]
Abstract
Fetal surgery has become a lifesaving reality for hundreds of fetuses each year. The development of a formidable spectrum of safe and effective minimally invasive techniques for fetal interventions since the early 1990s until today has led to an increasing acceptance of novel procedures by both patients and health care providers. From his vast personal experience of more than 20 years as one of the pioneers at the forefront of clinical minimally invasive fetal surgery, the author describes and comments on old and new minimally invasive approaches, highlighting their lifesaving or quality-of-life-improving potential. He provides easy-to-use practical information on how to perform partial amniotic carbon dioxide insufflation (PACI), how to assess lung function in fetuses with pulmonary hypoplasia, how to deal with giant CPAMS, how to insert shunts into fetuses with LUTO and hydrothorax when conventional devices are not available, and how to resuscitate a fetus during fetal cardiac intervention. Furthermore, the author proposes a curriculum for future fetal surgeons, solicits for the centralization of patients, for adequate maternal counseling, for adequate pain management and adequate hygienic conditions during interventions, and last but not least for starting the process of academic recognition of the matured field as an independent specialty. These steps will allow more affected expectant women and their unborn children to gain access to modern minimally invasive fetal surgery and therapy. The opportunity to treat more patients at dedicated centers will also result in more opportunities for the research of rare diseases and conditions, promising even better pre- and postnatal care in the future.

Abstract
ObjectiveThe anesthetic management of fetal operative procedures (FOP) is a highly debated topic. Literature on fetal pain perception and response to external stimuli is rapidly expanding. Nonetheless, there is no consensus on the fetal consciousness nor on the instruments to measure pain levels. As a result, no guidelines or clinical recommendations on anesthesia modality during FOP are available. This systematic literature review aimed to collect the available knowledge on the most common fetal interventions, and summarize the reported outcomes for each anesthetic approach. Additional aim was to provide an overall evaluation of the most commonly used anesthetic agents.MethodsTwo systematic literature searches were performed in Embase, Medline, Web of Science Core Collection and Cochrane Central Register of Controlled Trials up to December 2021. To best cover the available evidence, one literature search was mostly focused on fetal surgical procedures; while anesthesia during FOP was the main target for the second search. The following fetal procedures were included: fetal transfusion, laser ablation of placental anastomosis, twin-reversed arterial perfusion treatment, fetoscopic endoluminal tracheal occlusion, thoraco-amniotic shunt, vesico-amniotic shunt, myelomeningocele repair, resection of sacrococcygeal teratoma, ligation of amniotic bands, balloon valvuloplasty/septoplasty, ex-utero intrapartum treatment, and ovarian cyst resection/aspiration. Yielded articles were screened against the same inclusion criteria. Studies reporting anesthesia details and procedures’ outcomes were considered. Descriptive statistical analysis was performed and findings were reported in a narrative manner.ResultsThe literature searches yielded 1,679 articles, with 429 being selected for full-text evaluation. A total of 168 articles were included. Overall, no significant differences were found among procedures performed under maternal anesthesia or maternal-fetal anesthesia. Procedures requiring invasive fetal manipulation resulted to be more effective when performed under maternal anesthesia only. Based on the available data, a wide range of anesthetic agents are currently deployed and no consistency has been found neither between centers nor procedures.ConclusionsThis systematic review shows great variance in the anesthetic management during FOP. Further studies, systematically reporting intraoperative fetal monitoring and fetal hormonal responses to external stimuli, are necessary to identify the best anesthetic approach. Additional investigations on pain pathways and fetal pain perception are advisable.

Abstract
This article reviews the contemporary diagnosis and management of antenatally diagnosed congenital lung lesions. These anomalies, which include congenital pulmonary airway malformation (CPAM) (formerly congenital cystic adenomatoid malformation), bronchopulmonary sequestration (BPS), bronchogenic cyst, and congenital lobar emphysema (CLE), are relatively rare but are increasingly encountered by clinicians because of the improved resolution and enhanced sensitivity of fetal ultrasound. Serial assessment of these lesions throughout pregnancy remains the norm rather than the exception. Perinatal management strategies may differ based on initial size and growth patterns of these masses until delivery. Fetal magnetic resonance imaging and other diagnostic testing can sometimes be helpful in providing additional prognostic information. Over the last decade, maternal steroids have become standard of care in the management of larger lesions at risk for nonimmune hydrops. As a result, fetal surgical procedures, including open resection, thoracoamniotic shunting, and ex utero intrapartum treatment (EXIT), are less uncommonly performed. Decisions regarding whether delivery of these fetuses should occur in a tertiary care center with pediatric surgery coverage versus delivery at a local community hospital are now highly relevant in most prenatal counseling discussions with families. Large lung malformations may require urgent surgical removal in the early postnatal period because of respiratory distress. Other complications, such as recurrent pneumonia, pneumothorax, and cancer, are indications for postnatal lung resection on an elective basis. Many children are good candidates for minimally invasive (thoracoscopic) surgical approaches as an alternative to resection by thoracotomy. In the vast majority of cases, the overall prognosis remains excellent.

Abstract
Microcystic congenital cystic adenomatoid malformations (CCAM), when associated with hydrops, carry a dismal prognosis. Options for treatment are limited and experimental, including antenatal corticosteroids, open fetal surgery, laser ablation and, more recently, sclerotherapy. We describe a case of a large, predominantly microcystic CCAM in a hydropic fetus treated successfully with direct interstitial injection of a sclerosant agent (3% sodium tetradecyl sulfate) at 23+3 weeks gestation, after multiple failed courses of steroids. Elective thoracoscopic right lower lobectomy was performed at 1 year of life and there have been no respiratory or other medical morbidities since. A literature review of fetal lung masses treated with sclerosants antenatally reveals that sclerotherapy may represent a novel treatment option for large hydropic microcystic CCAMs, which are unresponsive to corticosteroids. Further studies are required to evaluate the utility and safety of fetal sclerotherapy, as this may represent an alternative minimally invasive treatment option to fetal lobectomy.

Abstract
Etiologies of fetal lung anomalies include congenital pulmonary airway malformation (CPAM), intra- or extralobar pulmonary sequestration, congenital high airway obstruction syndrome (CHAOS), bronchogenic cyst, and bronchial atresia. Fetal tracheobronchoscopy has been reported both as a diagnostic and therapeutic procedure in the setting of severe congenital lung lesions. In this case report, prenatal imaging of a fetus with a large chest mass was suspicious for an obstructive bronchial lesion. The absence of visible normal lung tissue on the right side and mass effect on the left side raised the concern for pulmonary hypoplasia. After antenatal betamethasone and a period observation, hydropic changes developed. Fetal tracheobronchoscopy was then performed in an effort to identify and decompress the suspected obstructive bronchial lesion. Other than release of bronchial debris, no anatomical abnormalities were visualized. However, the right lung lesion and mediastinal shift both decreased after the fetal bronchoscopy. The newborn underwent postnatal resection of a CPAM Type II and is doing well. We hypothesize that fetal tracheobronchoscopy provided the following potential diagnostic and therapeutic benefits: (1) exclusion of an obstructive bronchial lesion; (2) disimpaction of bronchial debris from the saline lavage that we posit may have contributed to the rapid reduction in CPAM size.

Abstract
OBJECTIVE To present outcomes of fetuses with congenital pulmonary airway malformation (CPAM) treated with sclerotherapy. METHODS Retrospective study of 8 patients with a prenatal diagnosis of CPAM type II or III with secondary hydrops treated with percutaneous sclerotherapy using 5% ethanolamine oleate (EO). All patients underwent ultrasonic measurement of the CPAM volume ratio. Results are expressed as median (range). RESULTS Gestational age at initial sclerotherapy was 22.0 weeks (19.6-31.4); 3 patients underwent 2 procedures. Intrauterine fetal demise (IUFD) occurred in 4 cases; 2 died on postoperative day #1 (one from inadvertent intravascular EO injection); 2 died >6 weeks after the procedure. Preoperative CPAM volume ratio was 3.6 (1.6-7.8) in survivors and 2.7 (1.7-4.7) in those with IUFD. The volume of EO at the initial sclerotherapy procedure was 3 mL (2-5) in survivors and 7 mL (6-10) in IUFD cases. The gestational age at delivery of the 4 survivors was 38.4 weeks (37.4-39.3); all underwent postnatal resection. CONCLUSION The efficacy of percutaneous sclerotherapy for CPAM types II and III remains in question. Further studies are needed to determine the optimal dose of sclerotherapy agent and the safety and efficacy of this procedure.

Abstract
INTRODUCTION A congenital pulmonary airway malformation (CPAM) type III may become large enough to cause hydrops fetalis. In such circumstances, the fetus can be treated with open fetal resection, maternal betamethasone administration, or percutaneous sclerotherapy. CASE REPORT A 24 week gestation fetus with a CPAM type III was treated by percutaneous sclerotherapy using ethanolamine oleate (EO). The EO inadvertently entered the left atrium and ventricle with subsequent fetal bradycardia and demise. Autopsy revealed myocardial necrosis. CONCLUSION Percutaneous sclerotherapy has been previously described in the literature for the treatment of microcystic CPAMs with secondary hydrops. This is the first reported case of an adverse event after fetal sclerotherapy.

Abstract
UNLABELLED Congenital pulmonary airway malformations or CPAM are rare developmental lung malformations, leading to cystic and/or adenomatous pulmonary areas. Nowadays, CPAM are diagnosed prenatally, improving the prenatal and immediate postnatal care and ultimately the knowledge on CPAM pathophysiology. CPAM natural evolution can lead to infections or malignancies, whose exact prevalence is still difficult to assess. The aim of this "state-of-the-art" review is to cover the recently published literature on CPAM management whether the pulmonary lesion was detected during pregnancy or after birth, the current indications of surgery or surveillance and finally its potential evolution to pleuro-pulmonary blastoma. CONCLUSION Surgery remains the cornerstone treatment of symptomatic lesions but the postnatal management of asymptomatic CPAM remains controversial. There are pros and cons of surgical resection, as increasing rate of infections over time renders the surgery more difficult after months or years of evolution, as well as risk of malignancy, though exact incidence is still unknown. What is known: • Congenital pulmonary airway malformations (CPAM) are rare developmental lung malformations mainly antenatally diagnosed. • While the neonatal management of symptomatic CPAM is clear and includes prompt surgery, controversies remain for asymptomatic CPAM due to risk of infections and malignancies. What is new: • Increased rate of infection over time renders the surgery more difficult after months or years of evolution and pushes for recommendation of early elective surgery. • New molecular or pathological pathways may help in the distinction of type 4 CPAM from type I pleuropulmonary blastoma.

Abstract
Massive microcystic congenital cystic adenomatoid malformation (CCAM) and bronchial atresia are associated with a high perinatal mortality secondary to lung hypoplasia and cardiac dysfunction, and fetal intervention should be considered to improve prognosis. Therapeutic options include open fetal surgery with pulmonary resection, fetal sclerotherapy and fetoscopy. We present a case with a severely enlarged left lung without ultrasound signs of dilated airways compatible with the diagnosis of microcystic CCAM, hydrops and severe contralateral lung hypoplasia that was treated successfully at 30 weeks of gestation by fetal bronchoscopy, through which bronchial atresia was identified at the end of the left mainstem bronchi and permeabilized by laser ablation. After fetal surgery, weekly follow-up showed a progressive decrease in the affected lung size and an increase in the contralateral hypoplastic lung size, demonstrating normal dimensions of both lungs at 34 weeks of gestation, reversal of the mediastinal shift, and complete disappearance of hydrops. A healthy neonate was delivered uneventfully at term with no need for respiratory support, and the boy is now doing well at 15 months of age. This report demonstrates that in cases with prenatal diagnosis of large microcystic CCAM, fetal bronchoscopy can be used to refine the diagnosis of bronchial atresia and as a therapeutic tool with good outcome.

Intrauterine therapy for macrocystic congenital cystic adenomatoid malformation of the lung. Obstet Gynecol Sci 2014; 57:102-8. [PMID: 24678482 PMCID: PMC3965692 DOI: 10.5468/ogs.2014.57.2.102] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2013] [Revised: 10/07/2013] [Accepted: 10/10/2013] [Indexed: 12/18/2022] Open
Abstract
OBJECTIVE To report on our experiences with thoracoamniotic shunting and/or the injection of a sclerosing agent (OK-432) to treat fetuses diagnosed with macrocystic congenital cystic adenomatoid malformation (CCAM) of the lung. METHODS A retrospective study was undertaken in six fetuses with macrocystic CCAM at our institute that had been confirmed by postnatal surgery between August 1999 and January 2012. RESULTS Six fetuses that had been diagnosed with macrocystic CCAM were analyzed. The median gestational age at diagnosis was 23.5 weeks (range, 19.5-31.0 weeks), and at the time of primary treatment was 24.0 weeks (range, 20.5-31.0 weeks). The mean size of the largest cyst at the initial assessment was 42.5±15 mm. Four fetuses were associated with mediastinal shifting, and one also showed fetal hydrops. All fetuses underwent a shunting procedure within the cysts, one case among them was also treated with OK-432. After the completion of all procedures, the mean size of the largest cyst was all decreased (14.2±12 mm). The median gestational age at delivery was 38.0 weeks (range, 32.4-40.3 weeks). All of the newborns underwent the surgical resection at a median age of 6 days (range, 1-136 days) and are currently doing well without any complications. CONCLUSION We suggest that intrauterine decompression therapy to manage fetal macrocystic CCAM is recommendable treatment for good perinatal outcome.

Abstract
Building upon over 30 years of experimental and clinical development, fetal surgery can be argued to be a standard of care for selected indications, though application of these techniques remains limited to a small number of highly selected fetuses, and availability to a small number of highly specialized centers. Despite its limited application to date, the field of fetal surgery continues to evolve, spurred both by technological advances allowing earlier and more accurate diagnosis of fetal anomalies as well as improved capability to intervene when appropriate. The efficacy of fetal surgical intervention has now been validated for selected indications by well-designed, randomized controlled trials. In this review, we summarize the evidence or lack thereof supporting the current most common indications for fetal surgical intervention.
