ABSTRACT
A hidropisia fetal não imune é a presença de duas ou mais (?2) coleções de líquido no feto na ausência de aloimunização Rh. As mais comuns etiologias incluem anormalidades cardiovasculares, cromossomiais e hematológicas, seguidas por anomalias estruturais fetais, complicações da gemelaridade, infecção, e patologia placentária. A avaliação da hidropisia começa com o teste de Coombs indireto para verificar se é verdadeiramente não imune, avaliação do feto e da placenta, incluindo a ecocardiografia (arritmia), exame da artéria cerebral média para identificar a anemia, assim como o cariótipo/microarranjo cromossomial, mesmo que não seja constatada anomalia estrutural fetal. O tratamento recomendado depende da etiologia subjacente e da idade da gravidez; o parto pré-termo será proposto apenas por indicações obstétricas, incluindo a síndrome do ?espelho?. São candidatos à avaliação anteparto e ao corticoide, casos idiopáticos ou com etiologia passível de tratamento pré-natal ou pós-natal. Essas gestações devem ser interrompidas em um centro terciário com UTI neonatal capaz de tratar recém-nascidos criticamente comprometidos. A aneuploidia confere um mau prognóstico e, mesmo na sua ausência, a sobrevida neonatal é frequentemente <50%. A síndrome do ?espelho? é uma forma grave de préeclâmpsia que pode se desenvolver com a hidropisia fetal e na maioria dos casos necessita da interrupção da gravidez.(AU)
The nonimmune hydrops is the presence of two or more (?2) fluid collections in the fetus in the absence of Rh alloimmunization. The most common causes include cardiovascular, chromosomal and hematological abnormalities, followed by fetal structural abnormalities, complications of twin pregnancy, infection, and placental pathology. The evaluation of hydrops begins with the indirect Coombs test to see if it is really not immune, evaluation of the fetus and placenta, including echocardiography (arrhythmia), examination of the middle cerebral artery to identify anemia, and karyotyping/chromosomal microarray even if it is not detected fetal structural anomalies. The recommended treatment depends on the underlying etiology and gestational age; preterm birth should be proposed only for obstetric indications, including the ?mirror? syndrome. The antepartum evaluation and corticosteroids are indicated in idiopathic cases or etiology capable of prenatal or postnatal treatment. These pregnancies should be discontinued in a tertiary center with neonatal intensive care units capable of treating critically compromised newborns. The aneuploidy confers a poor prognosis and even in the absence of aneuploidy neonatal survival is often <50%. The ?mirror? syndrome is a severe form of preeclampsia that can be developed with fetal hydrops and in most cases requires the interruption of pregnancy.(AU)

A hidropisia fetal não-imune (HFNI) é causada por um grupo heterogêneo de condições e atualmente corresponde à maior parte dos casos de hidropisia fetal. Em função da ampla diversidade etiopatogênica, a investigação dos casos de HFNI constitui um desafio diagnóstico. Esse estudo teve como objetivo a avaliação prospectiva e sistemática de uma série de casos de HFNI a partir de um protocolo de investigação ampliado, que incluiu a pesquisa de doenças metabólicas. O presente estudo também incluiu a revisão dos casos de HFNI registrados previamente pelo Programa de Genética Perinatal na maternidade da Unicamp. Durante aproximadamente dois anos (2010-2012), foram identificados 53 casos de HFNI. Nesse período, ocorreram 6.129 nascimentos na maternidade local, com registro de HFNI em 37 recém-nascidos, conferindo uma prevalência de 60 por 10.000 nascimentos, valor maior do que o observado no período anterior ao estudo (1987 a 2009). Para o restante da análise, quatro casos foram excluídos devido à impossibilidade de estudá-los adequadamente. A maioria dos hidrópicos nasceu pré-termo (43 - 73,5%). Houve registro de 23 nativivos (47%), 10 óbitos no período neonatal e 26 óbitos durante a gestação (53%), resultado em uma mortalidade geral (pré-natal e neonatal) de 73,4%. A hidropisia foi identificada no pré-natal na maioria dos casos (44 - 89,8%) e, apesar da condição ser comumente associada a mau prognóstico, em três pacientes (6,1%) houve resolução completa e espontânea da hidropisia durante a gestação. Os principais grupos diagnósticos encontrados foram: anomalias cromossômicas (17 casos - 34,7%), quadros sindrômicos (16,4% - oito casos), cardiopatias e infecções congênitas (8,2% - quatro casos cada). Os erros inatos do metabolismo (EIM) corresponderam a 6,1% da amostra (três casos de doenças de depósito lisossômico). Três casos (6,1%) foram classificados como idiopáticos.
Non-immune hydrops fetalis (NIHF) is caused by a hetereogenous group of conditions, currently accounting for the most cases of hydrops fetalis. Because of the wide etiopathogenic diversity, the investigation of NIHF cases constitutes a real diagnostic challenge. This study aimed to evaluate prospectively and systematically a series of NIHF cases from an expanded research protocol including the investigation of metabolic diseases. The present study also aimed to revise the NIHF cases previously recorded by Perinatal Genetics Program (PGP) in the maternity hospital of Unicamp. During approximately two years (2010-2012), 53 cases were identified. In this period, among 6,129 births that occurred in our hospital, NIHF was identified in 37 newborns, given a birth prevalence of 60 per 10,000, higher than that was observed in the previous period - 23:10,000 (1987-2009). For purpose of all other analysis, four of the 53 cases evaluated had to be excluded due to inability to assess them correctly. Most hydropic individuals were born preterm (43 - 73.5%). Twenty-three patients (47%) were live births, 10 of them died before hospital discharge; and 26 (53%) died in the prenatal period, given an overall mortality of 73.4%. The hydrops were identified in prenatal period in most cases (44 - 89.8%), and despite being commonly associated with poor prognosis, three cases (6.1%) had complete and spontaneous resolution of hydrops during pregnancy. The main diagnostic groups were chromosomal abnormalities (17 - 34.7%), syndromic (8 - 16.4%), isolated heart defects (4 - 8.2%), and congenital infections (4 - 8.2%). Inborn errors of metabolism (IEM) occurred in three cases (6.1%), all represented by lysosomal storage diseases. Three cases (6.1%) were classified as idiopathic.

Presentamos el caso de una gestante de 29 semanas que acude a urgencias por edemas en extremidades inferiores, un incremento ponderal en la última semana de 7 kg, oliguria y disnea. El feto presentaba un cuadro de ascitis y edema subcutáneo. Se realizó el diagnóstico de hidrops fetal no inmune, en el contexto de un síndrome de Ballantyne de causa desconocida. Inició trabajo de parto a los 7 días del ingreso y el puerperio cursó sin incidencias siendo dada de alta a las 48 horas post parto. El neonato precisó soporte respiratorio con ventilación no invasiva durante dos semanas y actualmente sigue controles periódicos en neonatología, con muy buena evolución.
We report a case of a 29 weeks pregnant who came to the emergency department because she presented oedema in lower extremity, weight increased in the last week of 7 kg, oliguria and dyspnoea. The fetus showed ascites and subcutaneous oedema. It was diagnosed a non-immune hydrops, in the context of Ballantyne syndrome of unknown cause. Childbirth was 7 days after admission and puerperium envolved normally, the patient was discharged at 48 hours postpartum. The neonate required respiratory support with non-invasive ventilation for two weeks and nowadays the baby is currently regular checks in neonatology, with a positive evolution.

OBJETIVO: Identificar a etiologia da hidropisia fetal não imune em gestantes diagnosticadas e encaminhadas para acompanhamento pré-natal. MÉTODOS: Estudo retrospectivo com análise dos casos de hidropisia fetal não imune que foram acompanhados entre março de 1992 e dezembro de 2011. Os casos tiveram confirmação diagnóstica pela presença de edema de subcutâneo fetal (≥5 mm) com derrame em pelo menos uma cavidade serosa por meio da ultrassonografia obstétrica, e a investigação etiológica foi realizada com pesquisa citogenética (cariótipo), infecciosa (sífilis, parvovírus B19, toxoplasmose, rubéola, citomegalovírus, adenovírus e herpes simples), hematológica e metabólica (erros inatos), além de com ecocardiografia fetal. Foram excluídas as gestações gemelares. A análise estatística foi efetuada pelo teste do χ² para aderência (software R 2.11.1). RESULTADOS: Foram incluídas 116 pacientes com hidropisia fetal não imune, sendo que 91 casos (78,5%) tiveram a etiologia elucidada e 25 casos (21,5%) foram classificados como causa idiopática. A etiologia cromossômica foi a que apresentou maior número de casos, totalizando 26 (22,4%), seguida da etiologia linfática com 15 casos (12,9%, sendo 11 casos de higroma cístico), da etiologia cardiovascular e da infecciosa com 14 casos cada (12,1%). Os demais casos tiveram etiologia torácica em 6,9% (oito casos), síndromes malformativas em 4,3% (cinco casos), tumores extratorácicos em 3,4% (quatro casos), metabólica em 1,7% (dois casos), hematológica, gastrintestinal e geniturinária em 0,9% cada (um caso cada). No período pós-natal, foram seguidos 104 casos por até 40 dias de vida, 12 casos tiveram morte fetal intrauterina. A sobrevida desses 104 recém-nascidos foi de 23,1% (24 sobreviveram). CONCLUSÃO: a etiologia da hidropisia diagnosticada na gestação deve tentar ser esclarecida, uma vez que está associada a um amplo espectro de doenças. É especialmente importante para determinar se uma condição potencialmente tratável está presente e para identificar doenças com risco de recorrência em futuras gestações para aconselhamento pré-concepcional adequado.
PURPOSE: To identify the etiology of nonimmune hydrops fetalis cases in pregnant women diagnosed and referred for prenatal care. METHODS: Retrospective analysis of cases with nonimmune hydrops fetalis that were monitored between March 1992 and December 2011. Diagnosis was confirmed by the presence of fetal subcutaneous edema (≥5 mm) with effusion in at least one serous cavity using obstetric ultrasound, and etiological investigation was conducted with cytogenetic (karyotype), infectious (syphilis, parvovirus B19, toxoplasmosis, rubella, cytomegalovirus, adenovirus and herpes simplex), hematologic and metabolic (inborn errors) analysis and fetal echocardiography. Twin pregnancies were excluded. Statistical analysis was performed using the χ² test for adhesion (software R 2.11.1). RESULTS: We included 116 patients with nonimmune hydrops fetalis; the etiology was elucidated in 91 cases (78.5%), while 25 cases (21.5%) were classified as idiopathic. Most cases had a chromosomal etiology, for a total of 26 cases (22.4%), followed by lymphatic etiology with 15 cases (12.9% with 11 cases of cystic hygroma), and cardiovascular and infectious etiology with 14 cases each (12.1%). In the remaining cases, the etiology was thoracic in 6.9% (eight cases), malformation syndromes in 4.3% (five cases), extrathoracic tumors in 3.4% (four cases), metabolic in 1.7% (two cases), and hematologic, gastrointestinal and genitourinary in 0.9% (one case each). During the postnatal period, 104 cases were followed up until the 40th day of life, and 12 cases had intrauterine fetal death. The survival rate of these 104 newborns was 23.1% (24 survived). CONCLUSION: An attempt should be made to clarify the etiology of hydrops diagnosed during pregnancy since the condition is associated with a wide spectrum of diseases. It is especially important to determine whether a potentially treatable condition is present and to identify disease at risk for recurrence in future pregnancies for adequate pre-conception counseling.

El citomegalovirus (CMV) es la infección viral congénita más frecuente con una prevalencia de 0,5% al nacimiento. La primoinfección aparece entre el 1-4% de las gestantes seronegativas. El 40% de estos fetos se infectan y un 10% presentan síntomas al nacimiento. Presentamos un caso de infección congénita por CMV con hidrops fetal, con afectación neonatal del sistema nervioso central. Se trató con ganciclovir intravenoso y posteriormente con valganciclovir oral hasta los 6 meses, con buenos resultados al año de vida. Se realiza una revisión bibliográfica del diagnóstico y pronóstico de los recién nacidos con infección congénita por CMV y las expectativas y experiencia actual del tratamiento con ganciclovir y valganciclovir.
Cytomegalovirus (CMV) is the leading cause of congenital infection affecting 0.5% of all live births. Primary CMV infection occurs in 1-4% of seronegative woman during pregnancy and may be transmitted to the fetus in 40%. Up to 10% of intrauterine CMV infections result in symptomatic congenital disease at birth. We present a case of congenital CMV infection in the third trimester of gestation with central nervous disease involvement, who was treated with intravenosus ganciclovir followed by oral valganciclovir for six months with successful results in the first year of life. We review the literature on the diagnosis and prognosis of newborns with congenital CMV infection and the expectations and current experience of treatment with ganciclovir and valganciclovir.

As lesões vasculares da placenta constituem um grupo de entidades distintas, mas inter-relacionadas, em que se incluem os corioangiomas e a corangiomatose multifocal difusa. O corioangioma é uma lesão nodular expansiva com incidência de cerca de 1 por cento. A corangiomatose multifocal difusa é rara (0,2 por cento) e predominante em placentas em idade gestacional inferior a 32 semanas. Os autores apresentam um caso de gestação gemelar monocoriônica/biamniótica, no qual um dos fetos, à 26ª semana de gestação, apresentou quadro de restrição de crescimento intrauterino, hidropisia e anemia associado à formação tumoral da placenta com vascularização aumentada verificada pela doplervelocimetria. O estudo anatomopatológico da placenta permitiu o diagnóstico de corangiomatose multifocal difusa. Este raro caso de corioangiomatose multifocal difusa com forma de apresentação pré-natal mimetizando a de um corioangioma comprova que a detecção ultrassonográfica de um tumor da placenta com vascularização aumentada deve suscitar outras hipótese diagnóstica, além do corioangioma.
Placenta vascular lesions are a group of distinct yet related entities that include chorangiomas and diffuse multifocal chorangiomatosis. Chorangioma is an expansive nodular lesion with an incidence of about 1 percent. Diffuse multifocal chorangiomatosis is rare (0.2 percent) and mostly seen in placentas before the 32nd gestational week. The authors present a case of a monochorionic/biamniotic twin pregnancy, in which, at the 26th gestational week, one fetus developed intrauterine growth restriction (IUGR), hydrops, and anemia associated with a tumor of the placenta with increased vascularization in the Doppler study. Pathological examination of the placenta diagnosed diffuse multifocal chorangiomatosis. This rare case report of diffuse multifocal chorangiomatosis with prenatal manifestations resembling those of a chorangioma proves that prenatal ultrasound detection of a placenta tumor, with increased vascularization at Doppler study, must raise other diagnostic possibilities beside chorangioma.

In a prospective case-control study, we compared the amniotic fluid amino acid levels in non-immune hydrops fetalis (NIHF) and normal fetuses. Eighty fetuses underwent amniocentesis for different reasons at the prenatal diagnosis unit of the Department of Obstetrics and Gynecology, Faculty of Medicine, Dicle University. Forty of these fetuses were diagnosed with NIHF. The study included 40 women each in the NIHF (mean age: 27.69 ± 4.56 years) and control (27.52 ± 5.49 years) groups, who had abnormal double- or triple-screening test values with normal fetuses with gestational ages of 23.26 ± 1.98 and 23.68 ± 1.49 weeks at the time of sample collection, respectively. Amniotic fluid amino acid concentrations (intra-assay variation: 2.26-7.85 percent; interassay variation: 3.45-8.22 percent) were measured using EZ:faast kits (EZ:faast GC/FID free (physiological) amino acid kit; Phenomenex, USA) by gas chromatography. The standard for quantitation was a mixture of free amino acids from Phenomenex. The levels of 21 amino acids were measured. The mean phosphoserine and serine levels were significantly lower in the NIHF group, while the taurine, α-aminoadipic acid (aaa), glycine, cysteine, NH4, and arginine (Arg) levels were significantly higher compared to control. Significant risk variables for the NIHF group and odds coefficients were obtained using a binary logistic regression method. The respective odds ratios and 95 percent confidence intervals for the risk variables phosphoserine, taurine, aaa, Arg, and NH4 were 3.31 (1.84-5.97), 2.45 (1.56-3.86), 1.78 (1.18-2.68), 2.18 (1.56-3.04), and 2.41 (1.66-3.49), respectively. The significant difference between NIHF and control fetuses suggests that the amniotic fluid levels of some amino acids may be useful for the diagnosis of NIHF.

La anemia diseritropoyética congénita se engloba dentro de un grupo raro y heterogéneo de trastornos eritrocitarios caracterizados por eritropoyesis ineficaz, anemia megaloblástica, hemosiderosis secundaria e hidrops fetal. Presentamos el caso de un feto de 20 semanas con hidrops como consecuencia de una anemia fetal intensa por eritropoyesis ineficaz. Ante el hallazgo de hidrops fetal no inmune es fundamental un diagnóstico etiológico precoz para ofrecer a la pareja las alternativas terapéuticas más adecuadas.
Congenital dyserythropoietic anemia is a rare group of heterogeneous disorders characterized by ineffective erythropoiesis, megaloblastic anemia, secondary hemosiderosis and fetal hydrops. We report a case of a 20 week old fetus with hydrops as a consequence of a severe fetal anemia resulting from ineffective erythropoiesis. When non-immune fetal hydrops is found, it is essential an early etiological diagnosis to give the parents the most appropriate therapeutic options.

Diagnóstico de un caso de enfermedad familiar a partir de un hidrops fetal. Gestante con 2 abortos previos ocurridos al inicio del segundo trimestre, ambos fetos masculinos. Se detecta en la semana 12 un higroma quístico en el contexto de un hidrops fetal. Estudio serológico (TORCH y parvovirus B12), con resultado negativo y biopsia corial con cariotipo 46 XY. La anamnesis y exploración detallada hacen sospechar una enfermedad ligada al cromosoma X, dado que la paciente y una hermana están afectas de una genodermatosis desde la infancia: Incontinentia Pigmenti.
We revealed a family disease by a fetal anomaly. The patient had a history of two early miscarriages of male fetuses. In the present pregnancy hydrops fetalis was demonstrated by routine ultrasound sean at 12 weeks. Serological tests were negative and chorionic villous sampling revealed normal karyotype, 46XY. We suspected a X-linked disease. Detailed family history leaded to the demonstration that the patient and a sister were affected of a rare genodermatosis: Incontinentia Pigmenti.

El hidrops fetal es una seria condición, la que tiene una compleja fisiopatología y se asocia a una variada gama de etiologías y un incierto pronóstico perinatal (mortalidad entre 60-90%). Pese a los avances en el campo de la Medicina Fetal, sólo existe posibilidad terapéutica en no más del 30% de los casos. Es necesario seguir investigando en las bases fisiopatológicas de la enfermedad, así como también estimular el diagnóstico precoz, especialmente de las causas relacionadas con malformaciones cardíacas y de paso, favorecer el asesoramiento genético a las parejas en riesgo.
Hydrops fetalis is a serious condition due to a complex pathophysiology, which is associated with a wide range of etiologic mechanisms leading to a poor pregnancy outcome (mortality of 60-90% of the cases). Management and therapeutic options are limited and can only be offered to one third of the cases. Investigation of the pathophysiologic basis as well as an early diagnosis would probably help in improving the outcome and genetic counseling of parents at risk for this condition.

We report the unique case of a patient of asiatic origin (chinese), who was evaluated, followed and treated at the Sonography Unit of the Maternity Ward, Clinical Hospital San Borja Arriarán (HCSBA), with the collaboration of the Fetal Medicine Unit, Clinical Hospital of the University of Chile. The patient presented a 30 weeks gestation, which at the moment of evaluation showed a fetus with noninmune Hydrops (mother RH(+), Du (-)). Perinatal evaluation discarded cardiopathy, aneuploidiesmarkers and other malformations accounting for this condition. Fetal ultrasonographic evaluation showed severe cardiac insufficiency, middle cerebral artery Doppler (MCA) suggestive of severe anemia and severe oligoamnios with normal kidneys. Dueto these fi ndings and to the asiatic origin of the patient, the ethiological possibilities of viral infection, B19 parvovirus or anemia of genetic origin such as alfa thalassemia were suggested. Cordocentesis shows hematocrite of 39 percent, discordant with the value estimated by MCA Doppler, which reduced the possibility of a viral origin. We sent a fetal blood sample for Hb electrophoresis. Given the critical hemodynamic conditions and having completed the profilaxis of the hyaline membrane, gestation is interrupted by cesarean section, getting a male NB weighing 2.400 gr, in poor condition, who dies at 10 hours from birth. Electrophoresis reported postcesarean section confirms the diagnosis.
Se reporta el caso inédito, de una paciente de origen asiático (China), evaluada, seguida y tratada en la Unidad de Ultrasonografía de la Maternidad del Hospital Clínico San Borja Arriarán (HCSBA), con la colaboración de la Unidad de Medicina Fetal del Hospital Clínico de la Universidad de Chile. La paciente cursaba un embarazo de 30 semanas al momento de ser evaluada en nuestra unidad donde se diagnosticó una gestación única con un feto que presentaba un hidrops no inmune (madre Rh(+), Du (-)). La evaluación perinatal descartó cardiopatía, marcadores de aneuploidía y otras malformaciones que explicaran dicha condición. La evaluación ultrasonográfica fetal mostraba insuficiencia cardiaca severa, Doppler de arteria cerebral media (ACM) sugerente de anemia severa, oligoamnios severo con riñones normales. Debido a estos hallazgos y al origen asiático de la paciente se plantea la posibilidad etiológica de una anemia por infección viral, (parvovirus B19), o una anemia de origen genético, como la alfa talasemia. La cordocentesis muestra un hematocrito de 39 por ciento, discordante con el valor estimado por Doppler de ACM, lo que alejaba la posibilidad de un origen viral y se envía muestra de sangre fetal para electroforesis de hemoglobina(Hb) fetales. Dada las condiciones hemodinámicas críticas y haber completado profilaxis de membrana hialina se interrumpe el embarazo mediante una cesárea obteniéndose un RN de sexo masculino de 2.400 g, hidrópico, en malas condiciones que fallece a las 10 horas de vida. La electroforesis de proteína de sangre fetal, informada post cesárea, confirma el diagnóstico de alfa talasemia.

Non-immune causes of hydrops fetalis are rare but frequently fatal. Identification of the cause for hydrops fetalis is essential to institute therapy. Chorangiomatosis and intestinal stenosis have not been previously reported as aetiological factors for the development of hydrops. We report a fetus born with hydrops associated with both of these conditions. A 1575 gms preterm neonate was born to a multigravida at 31 weeks of gestation. Emergency caesarean section was performed after detection of hydrops by prenatal ultrasonography. Baby had generalized edema at birth and died after 3 days due to progressive heart failure. At autopsy there was generalized edema and effusions. There were multiple stenotic segments in the intestine. Placenta showed numerous chorangiomas varying from 0.2 to 3 cm in diameter, hence diagnosed as diffuse multifocal chorangiomatosis. Examination of the placenta at neonatal autopsy is an essential part of assessment for hydrops fetalis. Chorangiomatosis is a rare and under reported condition which can cause prematurity, intrauterine growth retardation, pre-eclampsia and rarely hydrops fetalis.

El hidrops fetal no inmune (HFNI) es una importante causa de pérdida perinatal, con mortalidad que varía entre 50-100 por ciento. El HFNI es una condición causada por un grupo heterogéneo de patologías. La fisiopatología del desorden que lo produce se conoce en muchos casos. Sin embargo, existen muchos casos en que la causa no se puede detérminar. Presentar un caso de hidrops fetal no inmune, el estudio realizado y la revisión de la literatura. Un caso de hidrops fetal no inmune, fue diagnósticado por ultrasonido antenatal a las 298 semanas de gestación. El feto murió al nacer, el cariotipo de muestra de sangre obtenida del cordón umbilical fue anormal. El examen postmorten fue compatible con Síndrome de Tuner e Higroma Quístico. En el presente caso el HFNI fue causado por la cromosomopatía tipo monosomía X y la anatomía linfática denominada higroma quístico. Todos los casos de HFNI deben ser evaluados prenatalmente para un adecuado diagnóstico y tratamiento cuando la mortalidad es prevenible.

An intrauterine parvovirus B19 infection can result in severe fetal anemia and hydrops fetalis, which can lead to death. A case of fetal hydrops, diagnosed at 31 weeks gestation, is reported Cordocentesis revealed fetal hemoglobin of 5 g/dL. Due to fetal distress 18 hours later, the baby was delivered by emergency cesarean section and died two days later. Characteristic intra-nuclear inclusions in nucleated red blood cells were found in histopathological examinations of the liver and placenta, which supported the diagnosis of parvovirus B19 infection. Literatures about parvovirus B19 infection, especially intrauterine infection, its effects on the fetus, methods of diagnosis and management, were reviewed.

Objetivo: descrever um caso de hidropsia fetal não imune associada à pré-eclâmpsia precoce, tendo como causa primária a estenose da válvula cardíaca tricúspide fetal. Método: getsante de 29 anos, internada na Maternidade da Fundação Santa Casa de Misericórdia do Pará (FSCMPA), com 23 semanas de gestação, com o diagnóstico ultra-sonográfico de edema fetal generalizado, ascite fetal e edma de placenta e apresentando pré-eclâmpsia leve. A vitalidade fetal se encontrava preservada com 150 batimentos cardíacos fetais por minuto. O teste de Coombs indireto era negativo, excluindo a hidropsia fetal imune. a gestação evolui com imunência de eclâmpsia, sendo necessária a interrupção da gravidez por indução do parto com 24 semanas de gestação, devido o risco materno. o feto nasceu sem sinais vitais e a necropsia registrou sinais de insuficiência cardiáca congestiva e presença de estenose da válvula tricúspide, Conclusão: a hidropsia fetal não imune, apesar de rara, impõe um conhecimento aprofundado para possibilitar uma avaliação mais cuidadosa dos fetos hidrópicos, para que dependendo da causa da hidropsia, a intervenção precoce possa diminuir a mortalidade perinatal

Os aneurismas de átrio direito são entidades raramente relatadas na prática cardiológica, especialmente em vida intra-uterina, e podendo ser confundidos com derrame pericárdico e anomalia de Ebstein da valva tricúspide. Apresentamos revisão da literatura e ilustramos com caso de diagnóstico pré-natal de aneurisma de átrio direito cursando com sinais de hidropisia.
