Konno H, Okpaise OO, Sbragia L, Tonni G, Ruano R. Perinatal Outcomes of Intrauterine Interventions for Fetal Sacrococcygeal Teratoma Based on Different Surgical Techniques-A Systematic Review. J Clin Med 2024; 13:2649. [PMID: 38731178 PMCID: PMC11084939 DOI: 10.3390/jcm13092649] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 04/16/2024] [Accepted: 04/25/2024] [Indexed: 05/13/2024] Open
Abstract
Background: This study aims to evaluate the outcomes of fetal sacrococcygeal teratoma (SCT) submitted to prenatal interventions. Methods: We performed a systematic literature review of fetal SCT patients and compared the outcomes between open fetal surgery and percutaneous intervention. In addition, we also compared the results of SCT fetuses who did not undergo any surgical intervention (NI). Results: We identified 16 cases of open fetal surgery (OS), 48 cases of percutaneous fetal intervention (PI), and 93 NI patients. The survival rate was 56.2% in OS, 45.8% in PI (p = 0.568), and 71.0% in NI patients. The gestational age at delivery was earlier in cases where there was no survival compared to cases where the fetuses did survive across all evaluated cohorts (OS: p = 0.033, PI: p < 0.001, NI: p < 0.001). The gestational weeks at delivery in OS and PI fetuses were more similar; however, OS tended to be performed later on in pregnancy, and the affected fetuses had more severe presented findings. In our evaluation, we determined that the presence of fetal hydrops and cardiac failure had no significant impact on survival in SCT cases. In NI patients, polyhydramnios was much higher in fetuses who did not survive compared to their surviving cohorts (p < 0.001). Conclusions: In conclusion, gestational age at delivery can affect the short-term prognosis of fetuses affected with sacrococcygeal teratomas. Regardless of the mode of delivery or the necessity for intervention during the fetal period, monitoring for complications, including polyhydramnios, can prevent premature delivery.

Abstract
Fetal therapies undertaken to improve fetal outcome or to optimize transition to neonate life often entail some level of maternal, fetal, or neonatal risk. A fetal therapy center needs access to resources to carry out such therapies and to manage maternal, fetal, and neonatal complications that might arise, either related to the therapy per se or as part of the underlying fetal or maternal condition. Accordingly, a fetal therapy center requires a dedicated operational infrastructure and necessary resources to allow for appropriate oversight and monitoring of clinical performance and to facilitate multidisciplinary collaboration between the relevant specialties. Three care levels for fetal therapy centers are proposed to match the anticipated care complexity, with appropriate resources to achieve an optimal outcome at an institutional and regional level. A level I fetal therapy center should be capable of offering fetal interventions that may be associated with obstetric risks of preterm birth or membrane rupture but that would be very unlikely to require maternal medical subspecialty or intensive care, with neonatal risks not exceeding those of moderate prematurity. A level II center should have the incremental capacity to provide maternal intensive care and to manage extreme neonatal prematurity. A level III therapy center should offer the full range of fetal interventions (including open fetal surgery) and be able manage any of the associated maternal complications and comorbidities, as well as have access to neonatal and pediatric surgical intervention including indicated surgery for neonates with congenital anomalies.

Abstract
OBJECTIVE Evaluation of course and outcome of pregnancies with prenatally diagnosed fetal teratomas of various locations in a single center between 2002 and 2019. METHODS Retrospective observational single-center study including prenatally suspected or diagnosed fetal teratomas. Focus was put on ultrasound findings during pregnancy. Complications, need for intervention and outcomes were compared according to tumor location. RESULTS 79 cases of fetal teratomas were seen at our center between 2002 and 2019. Most frequent tumor locations were the sacrococcygeal region (59.5%), neck (20.2%) and oropharynx (7.6%). Complications mainly included polyhydramnios and cardiac compromise. Need for intervention during pregnancy was significantly higher in pericardial teratomas. Preterm birth before 37 and early preterm birth before 32 weeks occurred in 72.7% and 29.1%, respectively. Major causes of perinatal death were tumor bleeding in sacrococcygeal teratomas (SCTs) and respiratory failure in cervical and oropharyngeal teratomas. CONCLUSION There is a high need for intervention in pregnancies complicated by fetal teratomas. Pericardiocentesis in pericardial teratomas is often inevitable to reduce the risk of intrauterine demise. Amniotic fluid drainage in associated severe polyhydramnios helps to reduce the risk of preterm birth, a major cause of additional morbidity and mortality. MRI in supplement to prenatal ultrasound is useful in fetal teratomas of the neck and oropharynx in order to plan delivery.

Abstract
Congenital brain tumors, defined as those diagnosed prenatally or within the first 2 months of age, represent less than 2% of pediatric brain tumors. Their location, prevalence and pathophysiology differ from those of tumors that develop later in life. Imaging plays a crucial role in diagnosis, tumor characterization and treatment planning. The most common lesions diagnosed in utero are teratomas, followed by gliomas, choroid plexus papillomas and craniopharyngiomas. In this review, we summarize the pathogenesis, diagnosis, management and prognosis of the most frequent fetal brain tumors.

Abstract
Sacrococcygeal teratoma is one of the most common congenital tumors. Its optimal management requires interdisciplinary care by obstetricians, radiologists, pediatric surgeons, and neonatologists. Early surgery entailing complete tumor excision is the main therapy aim, but a substantial risk of life-threatening complications remains, especially uncontrollable intraoperative hemorrhage. To reduce the risk of bleeding in a female neonate with a giant sacrococcygeal teratoma, we successfully coil-embolized the tumor's main feeding arteries. Her subsequent complete surgical resection was uneventful, and the child is well with favorable reconstructive and functional status of all involved and adjacent organ systems.

Abstract
BACKGROUND Sacrococcygeal teratomas (SCT) are often highly vascularized and may result in high-output cardiac failure, polyhydramnios, fetal hydrops, and demise. Delivery is guided by the SCT to fetus volume ratio (SCTratio), SCT growth rate, and cardiac output indexed for weight (CCOi). METHODS We compared measurements and outcome in 12 consecutive fetuses referred with SCT. Adverse outcomes were: fetal surgery, delivery < 32 gestational weeks or neonatal demise. Only SCTratio and CCOi were used to manage the cases. SCT vascularization index (VI%) was derived from the 3D virtual organ computer-aided analysis (VOCAL) software. The SCTModel (modified from acardiac twins) calculated a hypothetical SCT draining vein size and derived a risk line, using diameters of the superior and inferior vena cava, the azygous and umbilical veins. VI% and a model of systemic and umbilical venous volumes (SCTModel) were tested as indicators for outcome in SCT. RESULTS Fetuses were monitored from 20.1 to 36.4 gestational weeks and 5/12 had adverse outcomes: 1 had successful open fetal surgery at 23.8 weeks and delivered at term, 4 delivered at < 32 weeks with 3/4 having neonatal demise between 25 and 29 weeks. VI% was significantly higher in cases with adverse outcomes (mean 10.3 [8.9-11.6] vs. 4.4 [3.4-5.3], p < 0.0001). The additional fraction of the fetal cardiac output required to perfuse the SCT-draining vein (XSCO%) (p = 0.46), SCTratio (p = 0.08), and CCOi (p = 0.64) were not significant. All cases with adverse outcome had VI% > 8%. The SCTModel risk line predicted nonadverse outcomes well but lacked data in 2/5 cases with adverse outcomes. CONCLUSIONS VI% is a significant indicator of SCT cases with adverse outcomes and combined with SCTratio may guide timing of delivery better than current measures.

Abstract
Ballantyne syndrome (BS) also called mirror syndrome is defined by the presence of a clinical triad that includes fetal hydrops and placental and maternal edema. Here we present a clinical case of a 34-year-old woman with a 29 weeks' pregnancy, who developed BS and fetal loss probably due to failure in prompt recognition of a rapidly growing sacrococcygeal teratoma (SCT). Due to similarities in clinical presentation with preeclampsia and the importance in early identification of the source for BS, we underwent a literature review in order to identify significant signs and symptoms, as well as sonographic changes, in order to help clinicians to make this prompt recognition, identification of the cause, and early management of BS, which will have an important impact in maternal and fetal survival.

Abstract
The International Fetal Medicine and Surgery Society was created in 1982 and proposed guidelines for fetal interventions that required demonstrations of the safety and feasibility of intended interventions in animal models prior to application in humans. Because of their short gestation and low cost, small animal models are useful in early investigation of fetal strategies. However, owing to the anatomic and physiologic differences between small animals and humans, repeated studies in large animal models are usually needed to facilitate translation to humans. Ovine (sheep) models have been used the most extensively to study the pathophysiology of congenital abnormalities and to develop techniques for fetal interventions. However, nonhuman primates have uterine and placental structures that most closely resemble those of humans. Thus, the nonhuman primate is the ideal model to develop surgical and anesthetic techniques that minimize obstetrical complications.

Abstract
The introduction of fetal magnetic resonance imaging (MRI) has improved the prenatal evaluation of uterine, placental and fetal anatomy. However, its utilization has mostly been restricted to fetal central nervous system anomalies. We review how adjunct fetal MRI was performed and diagnosis of cystic type IV sacrococcygeal teratoma was made. We also discuss the clinical relevance of fetal MRI in differentiating this lesion from other selected abdominal/pelvic cystic malformations and lesions.

Abstract
UNLABELLED OBJECT.: As more pediatric neurosurgeons become involved with fetal myelomeningocele closure efforts, examining refined techniques in the overall surgical approach that could maximize beneficial outcomes becomes critical. The authors compared outcomes for patients who had undergone a modified technique with those for patients who had undergone fetal repair as part of the earlier Management of Myelomeningocele Study (MOMS). METHODS Demographic and outcomes data were collected for a series of 43 delivered patients who had undergone in utero myelomeningocele closure at the Fetal Center at Vanderbilt from March 2011 through January 2013 (the study cohort) and were compared with data for 78 patients who had undergone fetal repair as part of MOMS (the MOMS cohort). For the study cohort, no uterine trocar was used, and uterine entry, manipulation, and closure were modified to minimize separation of the amniotic membrane. Weekly ultrasound reports were obtained from primary maternal-fetal medicine providers and reviewed. A test for normality revealed that distribution for the study cohort was normal; therefore, parametric statistics were used for comparisons. RESULTS The incidence of premature rupture of membranes (22% vs 46%, p = 0.011) and chorioamnion separation (0% vs 26%, p < 0.001) were lower for the study cohort than for the MOMS cohort. Incidence of oligohydramnios did not differ between the cohorts. The mean (± SD) gestational age of 34.4 (± 6.6) weeks for the study cohort was similar to that for the MOMS cohort (34.1 ± 3.1 weeks). However, the proportion of infants born at term (37 weeks or greater) was significantly higher for the study cohort (16 of 41; 39%) than for the MOMS cohort (16 of 78; 21%) (p = 0.030). Compared with 10 (13%) of 78 patients in the MOMS cohort, only 2 (4%) of 41 infants in the study cohort were delivered earlier than 30 weeks of gestation (p = 0.084, approaching significance). For the study cohort, 2 fetal deaths were attributed to the intervention, and both were believed to be associated with placental disruption; one of these mothers had previously unidentified thrombophilia. Mortality rates did not statistically differ between the cohorts. CONCLUSIONS These early results suggest that careful attention to uterine entry, manipulation, and closure by the surgical team can result in a decreased rate of premature rupture of membranes and chorioamnion separation and can reduce early preterm delivery. Although these results are promising, their confirmation will require further study of a larger series of patients.

Abstract
OBJECTIVE Large solid sacrococcygeal teratomas (SCT) can cause high-output cardiac failure and fetal or neonatal death. The aim of this study was to describe the outcomes of minimally invasive antenatal procedures for the treatment of fetal SCT. METHODS A case review was performed of five fetuses with a large SCT treated antenatally using minimally invasive techniques, and a systematic literature review on fetal therapy for solid SCTs was carried out. RESULTS Five women were referred between 17 + 5 and 26 + 4 weeks' gestation for a large fetal SCT with evidence of fetal cardiac failure. Vascular flow to the tumors was interrupted by fetoscopic laser ablation (n = 1), radiofrequency ablation (RFA; n = 2) or interstitial laser ablation ± vascular coiling (n = 2). There were two intrauterine fetal deaths. The other three cases resulted in preterm labor within 10 days of surgery. One neonate died. Two survived without procedure-related complications but had long-term morbidity related to prematurity. The systematic literature review revealed 16 SCTs treated minimally invasively for (early) hydrops. Including our cases, six of 20 hydropic fetuses survived after minimally invasive therapy (30%). Survival after RFA or interstitial laser ablation was 45% (5/11). Of 12 fetuses treated for SCT without obvious hydrops and for which perinatal survival data were available, eight (67%) survived. Mean gestational age at delivery after minimally invasive therapy was 29.7 ± 4.0 weeks. Survival after open fetal surgery in hydropic fetuses was 6/11 (55%), with a mean gestational age at delivery of 29.8 ± 2.9 weeks. CONCLUSIONS Fetal therapy can potentially improve perinatal outcomes for hydropic fetuses with a solid SCT, but is often complicated by intrauterine death and preterm birth.

Abstract
Fetal vascular lesions or malformations such as sacrococcygeal teratomas, cervical teratomas, chorioangiomas, and vein of Galen aneurysms are associated with an increased risk of fetal death due to cardiac failure and hydrops. Large vascular lesions have the potential to result in increased cardiac output and volume overload on the fetal heart. As the heart compensates for the increasing blood flow, cardiovascular changes, demonstrable on fetal echocardiography, are likely to occur in the fetus. In the current era of fetal intervention and surgery, it is important to characterize these changes as a means of recognizing cardiac dysfunction and selecting patients for fetal intervention and management. This retrospective study characterizes the echocardiographic findings in fetuses with vascular lesions or malformations using 2D, color, and pulsed-wave Doppler imaging.

Abstract
The field of neonatal surgery is now inextricably linked to the field of obstetrics. Neonatologists and surgical specialists experienced with the postnatal management and outcomes of infants with various disorders now look in utero along with obstetricians and fetal medicine specialists to characterize the development and well-being of fetuses with congenital anomalies with a goal to optimize fetal, perinatal and postnatal management. The purpose of this article is to examine how prenatal diagnosis and therapy has influenced neonatal surgery. An overview of prenatal diagnosis and the evolution of fetal therapy are provided. In addition, we review the impact of prenatal diagnosis and therapy on the management and outcomes of infants with specific anomalies, including congenital lung malformations, sacrococcygeal teratoma, myelomeningocele, giant fetal neck masses, diaphragmatic hernia and congenital heart defects.

Tumor volume to fetal weight ratio as an early prognostic classification for fetal sacrococcygeal teratoma. J Pediatr Surg 2011; 46:1182-5.

Abstract
PURPOSE This study was designed to develop a prognostic factor for fetuses with sacrococcygeal teratoma (SCT) that may be useful to predict outcome and guide counseling early in pregnancy. We hypothesize that, in fetuses with SCT, the ratio of tumor size to estimated fetal weight in the second trimester predicts outcome. METHODS We retrospectively reviewed charts of all patients evaluated at our Fetal Center for SCT between 2004 and 2009. Estimated fetal weight and tumor volume were calculated based on prenatal ultrasound or fetal magnetic resonance imaging. Patients were stratified based on tumor volume to fetal weight ratio (TFR), and their outcomes were analyzed by Fisher's Exact test. RESULTS Tumor volume to fetal weight ratio before 24 weeks' gestation was predictive of outcome. Those with a TFR less than or equal to 0.12 (n = 5) had a significantly better outcome than patients with a TFR greater than 0.12 (n = 5, P < .05). All patients with poor outcomes had a TFR greater than 0.12 by 24 weeks' gestation. A TFR greater than 0.12 predicted poor outcome with 100% sensitivity and 83% specificity. All 4 patients who developed hydrops had a TFR greater than 0.12. CONCLUSION In our series of fetuses with SCT, TFR before 24 weeks' gestation correlates with outcome. This novel, prenatal diagnostic tool may be useful in prenatal counseling and for early identification of high-risk fetuses.

Abstract
Fetal echocardiography was initially used to diagnose structural heart disease, but recent interest has focused on functional assessment. Effects of extracardiac conditions on the cardiac function such as volume overload (in the recipient in twin-twin transfusion syndrome), a hyperdynamic circulation (arterio-venous malformation), cardiac compression (diaphragmatic hernia, lung tumours) and increased placental resistance (intrauterine growth restriction and placental insufficiency) can be studied by ultrasound and may guide decisions for intervention or delivery. A variety of functional tests can be used, but there is no single clinical standard. For some specific conditions, however, certain tests have shown diagnostic value.

Abstract
Antenatal sonography has markedly increased the detection of urogenital anomalies, including those conditions that lead to significant morbidity and mortality. Prenatal intervention is feasible to arrest and sometimes reverse the sequelae of bladder outlet obstruction but not necessarily renal damage. Myelomeningoceles, the most severe form of spina bifida, can be corrected in utero, with improvements in hydrocephalus seen along with a decreased incidence of ventricular shunting postnatally. Medical therapy to prevent virilization associated with congenital adrenal hyperplasia has been successful, with improved ability to detect its presence prenatally now possible. As further techniques evolve to correct underlying disease processes, it becomes important to critically assess the therapies, particularly with long-term outcome data.

Abstract
Prenatal diagnosis provides insight into the in utero evolution of fetal thoracic lesions such as congenital cystic adenomatoid malformation (CCAM), bronchopulmonary sequestration (BPS), congenital lobar emphysema, and mediastinal teratoma. Serial sonographic study of fetuses with thoracic lesions has helped define the natural history of these lesions, determine the pathophysiologic features that affect clinical outcome, and formulate management based on prognosis.

Abstract
PURPOSE Sacrococcygeal teratoma (SCT) is the most common congenital neoplasm in neonates. We wished to assess the long-term functional outcome of children undergoing SCT resection. METHODS Records of neonates diagnosed with SCT from two surgeons' practices, and operated on between 1970 and 2006, were retrospectively reviewed. Patients/parents who consented to participate in the study received a questionnaire, focusing on fecal and urinary continence, constipation and lower extremity weakness. RESULTS Forty-six patients were identified. Four had died (3 from malignant tumors and 1 motor vehicle accident at 18 years). Of the 42 remaining cases, 39 were benign and 3 were malignant; 2 of the former developed malignant recurrences. Twenty-seven agreed to participate and 14 (52%) completed the questionnaire. Median age of respondents was 16.7 years (3-29), and none of the respondents had a recurrent tumor. Thirteen of the 14 respondents experienced no problem with urinary or fecal incontinence, or lower extremity weakness. The remaining patient had all three problems, but his SCT had involved the spinal cord. Of the ten patients who commented on constipation, one had significant constipation, five occasional constipation, and four no constipation. CONCLUSIONS Functional results after resection of neonatal SCT are excellent, with only a small number of patients reporting problems with fecal or urinary continence, or lower extremity weakness. Constipation is relatively common. This information is important for counseling families with fetal or neonatal SCT.

Abstract
BACKGROUND Sacrococcygeal teratoma (SCT) is the commonest neonatal neoplasm. Its long-term effects are important in prenatal counseling and the delivery of an appropriate postoperative plan. AIM To determine the long-term functional outcome after SCT excision in a UK regional center. STUDY DESIGN Follow-up data for all patients with a SCT excised at the John Radcliffe Hospital in Oxford was collected retrospectively from notes and prospectively in clinic visits. OUTCOME MEASURES Clinical evidence of bowel or bladder impairment, mortality. RESULTS Over a 14-year period, 18 patients had a histologic diagnosis of SCT. Nine patients (50%) were born, 7 (39%) were terminated, and 2 (11%) were stillbirths. Of the 9 patients who had SCT resection, 4 (44%) were antenatally diagnosed. There were no perioperative deaths and alpha-fetoprotein levels normalized by 6 to 12 months after tumor resection. Median follow-up of patients was 30 months (range: 6 to 132 mo) with 1 patient lost to follow-up at 6 months, although he was asymptomatic at the time. Three patients developed urologic complications (2 within 1 year of tumor resection), including 2 patients with neurogenic bladder dysfunction and 1 patient with detrusor sphincter dyssynergia. CONCLUSIONS Approximately one-third of patients will develop major urologic complications after resection of SCT. Routine ultrasonography in the first postoperative year after tumor resection may help to identify patients with neuropathic bladder at the early stage and predict late complications. Parents need to be aware of this potential long-term complication during prenatal counseling and the need for regular long-term follow-up with the pediatric surgical team.

Abstract
The development of hydrops fetalis and maternal mirror syndrome in the setting of fetal sacrococcygeal teratoma (SCT) carries a grave prognosis. Fetal surgery is not typically offered for hydropic fetuses beyond 26 weeks of gestational age. Few options exist for these families, and they are typically counseled to continue pregnancy until delivery is necessary for maternal indications or the fetus is 30 weeks old. Although a number of series report the survival of hydropic SCT infants delivered after 30 weeks of gestation, a paucity of information is available regarding the outcome of hydropic SCT infants delivered between 26 and 30 weeks of gestation. We now report successful postpartum resection and survival of a hydropic fetus delivered at 27 weeks for maternal mirror syndrome that may assist in counseling families in similar situations.

Abstract
OBJECTIVE To determine if gestational age (GA) at delivery or tumor size impacts outcome in neonates with very large sacrococcygeal teratomas (SCTs). METHODS Retrospective chart review from 1990 to 2006 of live-born infants with very large SCTs, defined as diameters exceeding 10 cm. Data analyzed using the independent t test and Fisher's exact test, with p values <0.05 considered significant. RESULTS Nine infants with very large SCTs were identified. Six of the 9 infants survived, 4 of whom had evidence of early hydrops. Mean GA of survivors was 32.2 +/- 3.7 versus 31.7 +/- 0.6 weeks in nonsurvivors (p = 0.85). Infants with the largest SCTs did not survive. CONCLUSION Risks of preterm delivery must be weighed against complications from further enlargement of very large SCTs and against the risks of in utero intervention.

Abstract
OBJECTIVE The purpose of this study was to determine whether prenatal MRI provides additional information about fetal sacrococcygeal teratoma compared with prenatal sonography. MATERIALS AND METHODS Twenty-two pregnant women with fetal sacrococcygeal teratoma underwent prenatal MRI (mean gestational age, 23 weeks). The size, location, mass characteristics, and compressive effects of the tumors were determined and correlated with sonography and postnatal findings. RESULTS Based on the MRI findings, the following American Academy of Pediatrics, Surgical Section classifications were assigned: type I in six patients, type II in 12, and type III in four. No type IV tumors were found. The sacrococcygeal teratoma appeared entirely cystic in five fetuses, microcystic in one, mixed cystic and solid in 12, and solid in four. The diagnosis of sacrococcygeal teratoma was accurate in all cases assessed at our center using both MRI and sonography. Two additional patients initially referred with the diagnosis of sacrococcygeal teratoma had a different diagnosis at reevaluation at our institution (healthy, n = 1; myelomeningocele, n = 1). MRI was superior to sonography for detecting displacement of the colon (n = 11), urinary tract dilatation (n = 9), hip dislocation (n = 4), intraspinal extension (n = 2), and vaginal dilation (n = 1). In fetuses with sacrococcygeal teratoma types II and III, MRI better showed the cephalic extent of the tumor compared with sonography. MRI findings were confirmed at surgery or autopsy in all patients. Three fetuses with high output cardiac physiology underwent open fetal resection of the tumor at 21-, 24-, and 26-weeks' gestational age with two surviving. CONCLUSION Our results show that ultrafast fetal MRI is a useful adjunct to the prenatal evaluation of fetal sacrococcygeal teratoma. Compared with sonography, MRI more accurately characterized the intrapelvic and abdominal extent of the tumors and provided more information on compression of adjacent organs. The additional anatomic resolution provided by MRI resulted in more accurate prenatal counseling and improved preoperative planning for surgical resection.

Abstract
With recent advances in technology, fetal sacrococcygeal teratoma is being diagnosed increasingly during the early prenatal period by ultrasound examination. In addition, early detection of tumor related complications such as polyhydramnios, congestive heart failure, hydrops, hemorrhage, urinary tract or bowel obstruction can be followed closely in utero. Active prenatal management can improve fetal perinatal outcome by allowing planned delivery for neonatal surgery [Chisholm, C.A. et al.: Am J Perinatol 1999;16:47-50] or in some cases, fetal intervention. Additionally, families can be counseled appropriately regarding the range of outcomes. We report a case of fetal sacrococcygeal teratoma Type I diagnosed at 20 weeks with a prominent vessel supplying the tumor mass. At 23 weeks, there was a sudden appearance of an additional lobular mass, consistent with intrauterine spontaneous ruptured of a sacrococcygeal teratoma mass.

Abstract
Sacrococcygeal teratomas are the most common tumors found in newborns and have a favorable outcome when diagnosed late in gestation. Solid, highly vascularized tumors diagnosed early in gestation have a higher incidence of hydrops fetalis and fetal demise. The following is a case report of a monochorionic twin gestation complicated by a solid highly vascular sacrococcygeal teratoma and the development of hydrops in the affected twin. In this case, serial ultrasound evaluations and timing of delivery optimized the outcome of the unaffected twin.

Abstract
Sacrococcygeal teratomas (SCTs) can present a challenging problem and can be associated with significant perinatal morbidity and mortality. A female child was born at 36 weeks' gestation with a large, vascular Type 1 SCT originally identified by prenatal ultrasound. A CT scan showed two large feeding vessels arising from both internal iliac arteries that were successfully embolized during angiography. A radiofrequency probe was then used to ablate a zone between normal tissue and the tumor. The SCT was subsequently surgically excised with minimal blood loss. This case is presented to illustrate two useful and previously unreported postnatal adjuncts to the surgical treatment of massive, hypervascular sacrococcygeal tumors.

Abstract
AIMS Sacrococcygeal teratomas (SCTs) are the commonest neonatal tumors with an incidence of approximately 1:30,000. There are few large single-center series and even fewer describing both their antenatal and postnatal course. We report the outcome of all fetuses investigated at a tertiary fetal medicine center with this diagnosis. METHOD Demographic details were obtained from a prospectively maintained database. Patient records were examined for additional data including antenatal and postnatal interventions. Data were described as median (range). RESULTS Forty-one SCTs were diagnosed antenatally during the period 1993 to 2004. Twelve were excluded from subsequent analysis (single antenatal visit or attending for second opinion [n = 6] and termination of pregnancy [n = 6]). Twelve underwent fetal intervention (laser vessel ablation [n = 4], alcohol sclerosis [n = 3], cyst drainage [n = 2], amniodrainage [n = 2], vesicoamniotic shunt [n = 1]) for fetal hydrops and polyhydramnios to aid in delivery and to prevent obstructive uropathy developing in the fetus. Of these, 3 died in utero and 9 survived to be born (median gestational age, 33 weeks [27-37 weeks]). A further 3 died in the neonatal period. There are 6 long-term survivors (50%) from this group. Seventeen infants, without intervention, were born at median gestational age 38 weeks (26-40 weeks). One infant with severe cardiac anomalies died on the day of birth. All surviving infants had definitive excisional surgery at a median of 2 days (1-16 days). Current median follow-up of survivors is 39 months (8-86 months). There have been no recurrences. One child has mild constipation, and 3 are awaiting cosmetic revision of their scars. CONCLUSIONS The overall survival of antenatally diagnosed SCT is approximately 77%, with the development of hydrops and others requiring in utero intervention carrying a poor prognosis. Otherwise, the outcome after surgical excision is excellent.

Abstract
OBJECTIVES There are shifts in fetal hemodynamics during open fetal surgery that were not appreciated until the use of intraoperative fetal echocardiography. We have developed an intraoperative monitoring strategy to continuously assess fetal hemodynamics. We hypothesized that this approach would enhance intraoperative management and survival. METHODS Medical records of open fetal surgery patients were reviewed since the implementation of this approach. Intraoperative fetal monitoring was accomplished by continuous echocardiography, pulse oximetry, establishment of intravenous access, and arterial blood gas and hemoglobin measurement. Overall survival was compared to fetal surgeries performed prior implementation of this monitoring strategy. RESULTS Resections of a congenital cystic adenomatoid malformation or a sacrococcygeal teratoma in nine hydropic fetuses were performed while using this monitoring strategy. Intraoperative echocardiography resulted in a change of management in 7 of 9 fetuses. The main observations on fetal echocardiography resulting in intraoperative intervention were decreased ventricular filling, bradycardia, and decreased ventricular contractility. Therapy included administration of volume expanders and/or inotropic agents. Overall fetal survival was 78% compared to a survival of 42% prior to the implementation of this approach. CONCLUSION Continuous intraoperative fetal monitoring provides real time assessment of fetal hemodynamics which results in changes in intraoperative management. The overall outcomes in these critically ill fetuses have been improved.

Abstract
In fetal tissues, both soft and hard tissue healing (in long bones) have been found to be scarless. However, healing of membranous bone in the fetal craniofacial skeleton has not been well documented. Pregnant ewes (gestational age range, 80-95 days) underwent a hysterotomy, and fetal lambs had a full-thickness excision of the entire mandibular symphysis region (10 mm). Nonoperated controls were used for comparison (n = 8). After 10 days and 2 weeks, fetuses showed incomplete regeneration of the anterior mandible by examination, computed tomographic scan, and histology. By 4 weeks postoperatively, the mandibular defect had completely closed, but regenerated bony volume was less than control specimens. At 6 weeks postoperatively, the specimen demonstrated complete bony healing without scar or inflammation. Computed tomographic scan measurements for mandibular shape (length over width) was similar in experimental and control specimens. The data indicate that fetal lamb membranous bone defects heal in a scarless fashion and suggest preprogrammed migration of osteogenic tissue.

Abstract
Background—
Prenatal surgery for congenital anomalies can prevent fetal demise or alter the course of organ development, resulting in a more favorable condition at birth. The indications for fetal surgery continue to expand, yet little is known about the acute sequelae of fetal surgery on the human cardiovascular system.
Methods and Results—
Echocardiography was used to evaluate the heart before, during, and early after fetal surgery for congenital anomalies, including repair of myelomeningocele (MMC, n=51), resection of intrathoracic masses (ITM, n=15), tracheal occlusion for congenital diaphragmatic hernia (CDH, n=13), and resection of sacrococcygeal teratoma (SCT, n=4). Fetuses with MMC all had normal cardiovascular systems entering into fetal surgery, whereas those with ITM, CDH, and SCT all exhibited secondary cardiovascular sequelae of the anomaly present. At fetal surgery, heart rate increased acutely, and combined cardiac output diminished at the time of fetal incision for all groups including those with MMC, which suggests diminished stroke volume. Ventricular dysfunction and valvular dysfunction were identified in all groups, as was acute constriction of the ductus arteriosus. Fetuses with ITM and SCT had the most significant changes at surgery.
Conclusions—
Acute cardiovascular changes take place during fetal surgery that are likely a consequence of the physiology of the anomaly and the general effects of surgical stress, tocolytic agents, and anesthesia. Echocardiographic monitoring during fetal surgery is an important adjunct in the management of these patients.

Abstract
Antenatal sonography has increased the detection of urogenital anomalies markedly, including conditions that lead to significant morbidity and mortality. Prenatal intervention is feasible to arrest and sometimes reverse the sequelae of bladder-outlet obstruction, but not necessarily renal damage. Myelomeningoceles, the most severe form of spina bifida,can be corrected in utero, with improvements in hydrocephalus and a decreased incidence of ventricular shunting postnatally. Medical therapy to prevent virilization associated with congenital adrenal hyperplasia has been successful, with improved ability to detect its presence prenatally. As techniques evolve to correct underlying disease processes,it becomes important to assess the therapies critically, particularly with long-term outcome data.

Abstract
Fetal surgery is now an accepted modality for treatment of a variety of lethal and non-lethal congenital conditions. It represents a new, fast-moving frontier of medicine in which cooperative mulitdisciplinary effort and input are required to assure both fetal and maternal welfare. A wide range of therapeutic strategies from percutaneous to open invasive techniques has led to a complex list of different procedures for different diseases. This review identifies the most common disease entities managed by fetal intervention, examines the evolution in development of techniques to those currently used, and describes the prospective, randomized trials presently underway that are designed to establish the safety and determine true efficacy of treatment. Fetal surgery as a (multi)discipline continues to strive to minimize maternal and fetal risk. Undoubtedly, as tocolytic therapy and neonatal intensive efforts improve, fetal therapy will expand.

Abstract
The majority of sacrococcygeal teratomas diagnosed before birth can be managed by planned delivery and postnatal surgery. However, large tumors early in gestation may result in placentomegaly, hydrops and fetal death and a preeclampsia-like syndrome in the mother. This is due to high output cardiac failure in the fetus caused by arteriovenous shunting through the tumor. In these cases, in utero treatment may offer improved chances of survival, and emerging technologies should lower fetal and maternal morbidity. Nevertheless, these therapeutics need to be correctly evaluated.

Abstract
PURPOSE To understand the natural history and define indications for fetal intervention in sacrococcygeal teratoma (SCT), the authors reviewed all cases of fetal SCT presenting for evaluation. METHODS Prenatal diagnostic studies including ultrasound scan, magnetic resonance imaging (MRI), echocardiography and pre- and postnatal outcomes were reviewed in 30 cases of SCT that presented between September 1995 and January 2003. RESULTS The mean gestational age (GA) at presentation was 23.9 weeks (range, 19 to 38.5) with 3 sets of twins (10%). Overall outcomes included 4 terminations, 5 fetal demises, 7 neonatal deaths, and 14 survivors. Significant obstetric complications occurred in 81% of the 26 continuing pregnancies: polyhydramnios (n = 7), oligohydramnios (n = 4), preterm labor (n = 13), preeclampsia (n = 4), gestational diabetes (n = 1), HELLP syndrome (n = 1), and hyperemesis (n = 1). Fetal intervention included cyst aspiration (n = 6), amnioreduction (n = 3), amnioinfusion (n = 1), and open fetal surgical resection (n = 4). Indications for cyst aspiration and amnioreduction were maternal discomfort, preterm labor, and prevention of tumor rupture at delivery. Although 15 SCTs were solid causing risk for cardiac failure, only 4 fetuses met criteria for fetal debulking based on ultrasonographic and echocardiographic evidence of impending high output failure and favorable anatomy at 21, 23.6, 25, and 26 weeks' gestation. Intraoperative events included maternal blood transfusion (n = 1), fetal blood transfusion (n = 2), chorioamniotic membrane separation (n = 2), and fetal arrest requiring successful cardiopulmonary resuscitation (CPR) (n = 1). In the fetal resection group, 3 of 4 survived with mean GA at delivery of 29 weeks (range, 27.6 to 31.7 weeks), mean birth weight of 1.3 kg, hospital stay ranging from 16 to 34 weeks, and follow-up ranging from 20 months to 6 years. Postnatal complications in the fetal surgery group included neonatal death (n = 1, secondary to premature closure of ductus arteriosus with cardiac failure), embolic event (n = 1, resulting in unilateral renal agenesis, jejunal atresia), chronic lung disease (n = 1), and tumor recurrence (n = 1). CONCLUSIONS For fetal SCT, the rapidity at which cardiac compromise can develop and the high incidence of obstetric complications warrant close prenatal surveillance. Amnioreduction, cyst aspiration, and surgical debulking are potentially life-saving interventions.

Abstract
We have learned from prenatal diagnosis that there is a wide spectrum of clinical severity for fetuses that have a lung mass. Accurate prognostic information is necessary for providing appropriate management and parental counseling. If an associated life-threatening anomaly is present or if the mother is ill with the mirror syndrome, then the family might choose to terminate the pregnancy. If the fetus is not hydropic and an isolated fetal lung lesion is present, the mother is followed by serial ultrasound and arrangements are made for the best possible care after birth. Some CCAMs and many BPSs will shrink in size, so it is important to try to differentiate these lesions using prenatal diagnostic criteria, although this technique is not always possible. All fetuses that had fetal thoracic masses without hydrops in our series survived in the setting of maternal transport, planned delivery, and postnatal evaluation at a facility with ECMO capability. Many of the babies that had large lesions at our center required ventilatory support, and six babies needed treatment with ECMO. Our impression is that these nonhydropic fetuses that had lung masses had less lung hypoplasia and a much better prognosis than those that had diaphragmatic hernia despite a similar degree of mediastinal shift as judged by prenatal sonography. In asymptomatic neonates that have a cystic lung lesion, we believe that elective resection is warranted because of the risks of infection and occult malignant transformation. Malignancies consist mainly of pleuropulmonary blastoma in infants and young children and bronchioloalveolar carcinoma in older children and adults. After confirmation of CCAM location by postnatal chest CT scan with intravenous contrast, we recommend elective resection at 1 month of age or older. This age has been chosen because anesthetic risk in babies decreases after 4 weeks of age. An experienced pediatric surgeon can safely perform a lobectomy in infants with minimal morbidity. Early resection also maximizes compensatory lung growth. In contrast, we have usually followed patients with a tiny, asymptomatic, noncystic BPS if we are confident of the diagnosis based on postnatal imaging studies. We do not favor the approach of catheterization and embolization for the treatment of larger BPS lesions. If the fetus is hydropic at presentation or if hydrops develops during serial follow-up, management depends upon the gestational age. For hydropic fetuses of greater than 32 weeks' gestation, early delivery should be considered so that the lesion can be resected ex utero, but the neonatal outcome is dismal. We recently managed two such cases using an ex utero intrapartum therapy (EXIT) strategy with resection of the mass during the EXIT procedure. Both fetuses survived and one required the use of ECMO. For hydropic fetuses of less than 32 weeks' gestation, there is now a new therapeutic option, treating the lesion before birth.

Abstract
These four individuals are recognized because at a critical point in the evolution of maternal-fetal surgery they contributed in ways that uniquely advanced progress in the field, enabling other researchers to make even greater discoveries. They were not the only significant contributors; there were many, too numerous to recount. Although their contributions were crucial, other researchers accomplished more. Among their peers, however, these four pioneers stand out because at a critical nexus their vision and perseverance carried researchers forward to a new level of excellence. We all follow in their footsteps.

Abstract
A great deal has been learned regarding the natural history and pathophysiology of fetal SCT. The logic behind fetal intervention for SCT and hydrops appears to be correct, and open and minimal access techniques of fetal intervention have been shown to be feasible. The development of fetal intervention for SCT has mirrored those developed for other diseases such as congenital diaphragmatic hernia. In a recent presentation, Harrison, the original pioneer in fetal surgery, outlined trends in fetal intervention. The first trend is that of moving from open, invasive techniques to minimally invasive techniques. In the case of SCT surgeons are moving from open resection to RFA and possibly to fetoscopic resection. The second trend outlined by Harrison is a movement away from total in utero repair of a defect that recapitulates postnatal treatment and toward manipulation of fetal pathophysiology to reverse life-threatening events. In SCT surgeons employ RFA to ablate causative blood vessels to reverse fetal hydrops with the knowledge that these fetuses will require postnatal resection of the tumor. In contrast to resection, RFA requires less time and significantly less maternal morbidity than open resection. Further study is required to determine the role of minimal access techniques in SCT. Future directions for treatment of fetal SCT with hydrops might include fetoscopic resection or high-intensity ultrasound ablation.

Abstract
Sacrococcygeal teratoma is a rare fetal neoplasm with an incidence of 1 in 40,000 births. Antenatal diagnosis is usually made after 22 weeks of gestation. Fetuses with this malformation are at risk of significant perinatal morbidity and mortality. Malignant components, coexisting with life-threatening anomalies, and chromosomal abnormalities are rare. Postulated causes of perinatal death include hydrops, dystocia, tumor rupture, preterm labor secondary to polyhydramnios, and anemia due either to hemorrhage or hemolysis within the tumor. Herein, we present a case of fetal sacrococcygeal teratoma diagnosed as early as 17 weeks of gestation.

Abstract
The development of fetal surgery has led to promising therapeutic options for a number of congenital malformations. However, preterm labor (PTL) and premature rupture of membranes continue to be ubiquitous risks for both mother and fetus. To reduce maternal morbidity and the risk of prematurity, minimal access surgical techniques were developed and are increasingly employed. Congenital diaphragmatic hernia (CDH), obstructive uropathy, twin-to-twin transfusion syndrome (TTTS), and sacrococcygeal teratoma have already been successfully treated using minimal access fetal surgical procedures. Other life-threatening diseases as well as severely disabling but not life-threatening conditions are potentially amenable to treatment. The wider application of minimal access fetal surgery depends on a continued improvement in technology and a better understanding of complications associated with fetal intervention.

Abstract
Advanced prenatal ultrasonography techniques have allowed for better understanding of the natural history, treatment, and prognosis of sacrococcygeal teratomas. Several intrauterine surgical techniques to debulk the tumor when fetal and maternal life are in jeopardy have been described. Orthopaedic impairment, such as lower extremity weakness and swelling, also has been described in association with sacrococcygeal teratomas. The authors report on a newborn in whom a large soft tissue defect overlying the posterior hip region with direct exposure of the disarticulated hip joint existed at the time of birth, which resulted from intrauterine radiofrequency ablation of a sacrococcygeal teratoma. This unexpected complication has resulted in a loss of sciatic nerve function, malformation of the acetabulum and femoral head, and loss of the left ischium, coccyx, inferior sacrum, gluteal, adductor and piriformis muscles, and posterior hip capsule. At 16 months of age, the patient has a flaccid left lower extremity with a hypoplastic hip joint.

Abstract
BACKGROUND/PURPOSE In the last 10 years, the ability to diagnose fetal tumors in the prenatal period has improved greatly because of technical advances in imaging. Early diagnosis and determination of tumor may affect prognosis. METHODS The authors retrospectively reviewed the records of 1316 fetuses who underwent sonographic evaluation for congenital defects at University of California-San Francisco over a 6-year period. Of these, 16 had fetal tumors and were followed up at our institution. There were solid or predominantely solid with small cystic component masses in one of 3 locations: cervical, mediastinal, or abdominal. Excluded from our study were those fetuses with either sacrococcygeal teratoma, congenital cystic adenomatoid malformation of the lung, or ovarian cyst, because these defects have been extensively reviewed elsewhere. In addition, masses that were primarily cystic also were excluded. Data collected included diagnosis, gestational age at diagnosis and at delivery, mode of delivery, fetal and neonatal survival, and disease confirmation. RESULTS Of the 16 fetuses, 4 had mediastinal tumors: 2 with pericardial teratomas (both of whom died in utero) and 2 with cardiac rhabdomyomas (1 died; the other presented tuberous sclerosis and is alive at 2 years of age). Four patients had cervical tumors (3 died; 1 survived and is alive and well), and 8 had abdominal tumors (3 with liver tumors, 4 with a left adrenal mass, and 1 with retroperitoneal teratoma). All eight patients with an abdominal tumor are alive and well. CONCLUSIONS Fetal tumors are rare, and the prognosis seems to depend on their location and size. Although easier to detect, cervical and mediastinal tumors have a worse prognosis. Abdominal masses are more difficult to detect but have a better prognosis.

Abstract
BACKGROUND/PURPOSE Sacrococcygeal teratomas (SCT) diagnosed in utero have been reported to be large and associated with high perinatal mortality rate. However, operative management including timing of operation after birth, combined abdominal approach for devascularization, and the position of the patients during resection is not well established. METHODS A retrospective review of 14 patients with SCT between 1978 and 1999 was performed. To prevent massive bleeding during surgery, the authors used an abdominoperineal resection in the supine position after devascularization. The patients' clinical and sonographic characteristics, prenatal outcome, operative management, and postnatal outcomes were examined. RESULTS One fetus died in utero. Two patients died within a week, but no late death and no malignant degeneration were noted. A staged operation with devascularization was performed in 2 patients, and 1 death occurred. Surgical management was analyzed between survivors without massive bleeding at surgery (n = 9) and others (n = 4). A significant difference was observed in the subgroup of tumor resection with devascularization or supine position and that of early resection with devascularization or supine position. CONCLUSIONS Early resection using the abdominoperineal approach supported by close antenatal sonography may be preferable for a favorable outcome. Resection in the supine position after devascularization may have advantages of respiratory management, cardiac resuscitation, and bleeding prevention. J Pediatr Surg 36:545-548.

This is the first report in which a percutaneous technique, radiofrequency ablation, was used to interrupt blood flow to a sacrococcygeal teratoma in 4 human fetuses. STUDY DESIGN A radiofrequency ablation probe was percutaneously inserted into the fetal tumor under ultrasonographic guidance. In 2 fetuses a significant portion of the tumor mass was ablated, whereas in the other 2 fetuses only the major feeding vessels were targeted. RESULTS Two infants were delivered at 28 and 31 weeks' gestation, respectively, and are doing well. In 2 other cases hemorrhage into the tumor led to an unfavorable fetal outcome. CONCLUSION Ablation of a majority of the tumor tissue in sacrococcygeal teratoma is not necessary and proved fatal in two instances. Targeted ablation of the feeding tumor vessels diminishes blood flow sufficiently to reverse high-output fetal heart failure.
