RESUMEN
Resumo Fundamento: Em doentes com infarto agudo do miocárdio (IAM), choque cardiogênico (CC) e doença multivaso (DMV) persistem dúvidas sobre a intervenção nas artérias não responsáveis. Objetivos: 1) caracterizar a amostra de doentes com IAM, CC e DMV incluídos no Registo Nacional Português de Síndromes Coronárias Agudas (RNSCA); 2) comparar os eventos associados a diferentes estratégias de revascularização; e 3) identificar preditores de mortalidade intra-hospitalar nesta amostra. Métodos: Estudo observacional retrospetivo de doentes com IAM, CC e DMV incluídos no RNSCA entre 2010 e 2018. Compararam-se duas estratégias de revascularização: completa durante o procedimento índice (grupo 1); e completa diferida ou incompleta durante o internamento (grupo 2-3). O endpoint primário foi a ocorrência de reinfarto ou morte intra-hospitalar. A significância estatística foi definida por um valor p < 0,05. Resultados: Identificaram-se 127 doentes com IAM, CC e DMV (18,1% no grupo 1 e 81,9% no grupo 2-3), com idade média de 70 ± 12 anos e 92,9% com IAM com supradesnivelamento do segmento ST. O endpoint primário ocorreu em 47,8% dos doentes do grupo 1 e em 37,5% do grupo 2-3 (p = 0,359). As taxas de mortalidade intra-hospitalar, reinfarto, acidente vascular cerebral e hemorragia major foram também semelhantes nos dois grupos. Os preditores de mortalidade intra-hospitalar nesta amostra foram a presença na admissão de disfunção ventricular esquerda (OR 16,8), bloqueio completo de ramo direito (OR 7,6) e anemia (OR 5,2), (p ≤ 0,02). Conclusões: Entre os doentes com IAM, CC e DMV, incluídos no RNSCA, não se verificou diferença significativa entre revascularização completa no evento índex e completa diferida ou incompleta durante o internamento, relativamente à ocorrência de morte intra-hospitalar ou reinfarto.

Abstract Background: In patients with acute myocardial infarction (MI), cardiogenic shock (CS), and multivessel disease (MVD) questions remain unanswered when it comes to intervention on non-culprit arteries. Objective: This article aims to 1) characterize patients with MI, CS and MVD included in the Portuguese Registry on Acute Coronary Syndromes (ProACS); 2) compare different revascularization strategies in the sample; 3) identify predictors of in-hospital mortality among these patients. Methods: Observational retrospective study of patients with MI, CS and MVD included in the ProACS between 2010 and 2018. Two revascularization strategies were compared: complete during the index procedure (group 1); and complete or incomplete during the index hospitalization (groups 2-3). The primary endpoint was a composite of in-hospital death or MI. Statistical significance was defined by a p-value <0.05. Results: We identified 127 patients with MI, CS, and MVD (18.1% in group 1, and 81.9% in groups 2-3), with a mean age of 7012 years, and 92.9% of the sample being diagnosed with ST-segment elevation MI (STEMI). The primary endpoint occurred in 47.8% of the patients in group 1 and 37.5% in group 2-3 (p = 0.359). The rates of in-hospital death, recurrent MI, stroke, and major bleeding were also similar. The predictors of in-hospital death in this sample were the presence of left ventricle systolic dysfunction on admission (OR 16.8), right bundle branch block (OR 7.6), and anemia (OR 5.2) (p ≤ 0.02 for both). Conclusions: Among patients with MI, CS, and MVD included in the ProACS, there was no significant difference between complete and incomplete revascularization during the index hospitalization regarding the occurrence of in-hospital death or MI.

Abstract Backgrund: New-onset atrial fibrillation complicating acute myocardial infarction represents an important challenge, with prognostic significance. Objective: To study the incidence, impact on therapy and mortality, and to identify predictors of development of new-onset atrial fibrillation during hospital stay for ST-segment elevation myocardial infarction. Methods: We studied all patients with ST-elevation myocardial infarction included consecutively, between 2010 and 2017, in a Portuguese national registry and compared two groups: 1 - no atrial fibrillation and 2 - new-onset atrial fibrillation. We adjusted a logistic regression model data analysis to assess the impact of new-onset atrial fibrillation on in-hospital mortality and to identify independent predictors of its development. A p value < 0.05 was considered significant. Results: We studied 6325 patients, and new-onset atrial fibrillation was found in 365 (5.8%). Reperfusion was successfully accomplished in both groups with no difference regarding type of reperfusion. In group 2, therapy with beta-blockers and angiotensin-conversion enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs) was less frequent, 20.6% received anticoagulation at discharge and 16.1% were on triple therapy. New-onset atrial fibrillation was associated with more in-hospital complications and mortality. However, it was not found as an independent predictor of in-hospital mortality. We identified age, prior stroke, inferior myocardial infarction and complete atrioventricular block as independent predictors of new-onset atrial fibrillation. Conclusion: New-onset atrial fibrillation remains a frequent complication of myocardial infarction and is associated with higher rate of complications and in-hospital mortality. Age, prior stroke, inferior myocardial infarction and complete atrioventricular block were independent predictors of new onset atrial fibrillation. Only 36.7% of the patients received anticoagulation at discharge.
Resumo Fundamento: A fibrilação auricular de novo no contexto de infarto agudo do miocárdio representa um importante desafio com potencial impacto prognóstico. Objetivo: Determinar a incidência, impacto na terapêutica e mortalidade, e identificar possíveis preditores do aparecimento de fibrilação auricular de novo durante o internamento por infarto agudo do miocárdio com supradesnivelamento do segmento ST. Métodos: Estudamos todos os pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST inseridos consecutivamente de 2010 a 2017 num registro nacional português e comparamos dois grupos: 1 - sem fibrilação auricular; 2- com fibrilação auricular de novo. Efetuamos análise com modelo de regressão logística para avaliar o impacto de fibrilação auricular de novo na mortalidade intra-hospitalar e identificar preditores independentes para o seu aparecimento. Para teste de hipóteses, considerou-se significativo p < 0,05. Resultados: Estudamos 6325 pacientes, dos quais 365 (5.8%) apresentaram fibrilação auricular de novo. Não houve diferença no número de pacientes reperfundidos nem na estratégia de reperfusão. No grupo 2, terapêutica com betabloqueadores e IECA/ARA foi menos frequente, 20.6% tiveram alta sob anticoagulação oral e 16.1% sob terapêutica tripla. A fibrilação auricular de novo associou-se a maior incidência de complicações e mortalidade intra-hospitalar, mas não foi preditor independente de mortalidade intra-hospitalar. Identificamos idade, acidente vascular cerebral prévio, infarto inferior e bloqueio auriculoventricular completo como preditores independentes de fibrilação auricular de novo. Conclusões: A fibrilação auricular de novo continua sendo uma complicação frequente do infarto agudo do miocárdio, estando associada a aumento das complicações e mortalidade intra-hospitalar. Apenas 36.7% desses pacientes teve alta sob anticoagulação.

Introdução: a displasia cemento-óssea periapical (DCOP) é uma lesão idiopática benigna mais prevalente na região de incisivos centrais inferiores, em mulheres negras, na faixa etária dos 30 aos 50 anos. Apresenta características radiográficas que podem levar o cirurgião-dentista a um diagnóstico e plano de tratamento equivocados, por ser confundida com periapicopatias. Objetivo: o objetivo do presente artigo foi, por meio de uma revisão de literatura, descrever essa patologia. Métodos: essa revisão foi feita por meio de buscas em duas das principais bases de dados mundiais: PubMed e SciELO. Para isso, foram usados os descritores "periapical cementoosseus dysplasia" e "displasia cemento-óssea periapical", com o objetivo de se avaliar o conteúdo sobre essa temática na literatura atual. Resultados: foram coletados 24 artigos científicos que obedeciam aos seguintes critérios de inclusão: ser uma revisão de literatura ou caso clínico; escrito em língua portuguesa ou inglesa, nos períodos de 1989 a 2016; contemplando a etiologia, características clínicas e radiográficas, diagnóstico, plano de tratamento e prognóstico referentes à displasia cemento-óssea periapical. Conclusão: é importante para o profissional reconhecer os aspectos relevantes da DCOP, a fim de elucidar o diagnóstico diferencial e tratamento e, assim, evitar procedimentos iatrogênicos, tais como terapias endodônticas desnecessárias.

OBJECTIVE:: To compare patients without previously diagnosed cardiovascular risk factors) and patients with one or more risk factors admitted with acute coronary syndrome. METHODS:: This was a retrospective analysis of patients admitted with first episode of acute coronary syndrome without previous heart disease, who were included in a national acute coronary syndrome registry. The patients were divided according to the number of risk factors, as follows: 0 risk factor (G0), 1 or 2 risk factors (G1 - 2) and 3 or more risk factors (G ≥ 3). Comparative analysis was performed between the three groups, and independent predictors of cardiac arrest and death were studied. RESULTS:: A total of 5,518 patients were studied, of which 72.2% were male and the mean age was 64 ± 14 years. G0 had a greater incidence of ST-segment elevation myocardial infarction, with the left anterior descending artery being the most frequently involved vessel, and a lower prevalence of multivessel disease. Even though G0 had a lower Killip class (96% in Killip I; p < 0.001) and higher ejection fraction (G0 56 ± 10% versus G1 - 2 and G ≥ 3 53 ± 12%; p = 0.024) on admission, there was a significant higher incidence of cardiac arrest. Multivariate analysis identified the absence of risk factors as an independent predictor of cardiac arrest (OR 2.78; p = 0.019). Hospital mortality was slightly higher in G0, although this difference was not significant. By Cox regression analysis, the number of risk factors was found not to be associated with mortality. Predictors of death at 1 year follow up included age (OR 1.05; p < 0.001), ST-segment elevation myocardial infarction (OR 1.94; p = 0.003) and ejection fraction < 50% (OR 2.34; p < 0.001). CONCLUSION:: Even though the group without risk factors was composed of younger patients with fewer comorbidities, better left ventricular function and less extensive coronary disease, the absence of risk factors was an independent predictor of cardiac arrest.

RESUMO Objetivo: Comparar pacientes admitidos com síndrome coronariana aguda sem prévia identificação de fatores de risco cardiovascular com pacientes que portavam um ou mais fatores de risco. Métodos: Análise retrospectiva dos pacientes admitidos com o primeiro episódio de síndrome coronariana aguda sem cardiopatia prévia, incluídos em um registro nacional de síndrome coronariana aguda. Os pacientes foram divididos segundo o número de fatores de risco: nenhum fator de risco (G0), um ou dois fatores de risco (G1 - 2) e três ou mais fatores de risco (G ≥ 3). Realizou-se uma análise comparativa entre os três grupos e se estudaram os preditores independentes de parada cardíaca e óbito. Resultados: O total apurado foi de 5.518 pacientes, 72,2% deles do sexo masculino, com média de idade de 64 ± 14 anos. O G0 teve uma incidência maior de infarto do miocárdio com elevação do segmento ST, sendo o vaso mais frequentemente envolvido a artéria descendente anterior esquerda, e menor prevalência de envolvimento de múltiplos vasos. Embora o G0 tivesse uma classe Killip mais baixa (96% Killip I; p < 0,001) e maior fração de ejeção (G0: 56 ± 10% versus G1 - 2 e G ≥ 3: 53 ± 12%; p = 0,024) na admissão, houve incidência significantemente maior de parada cardíaca. A análise multivariada identificou ausência de fatores de risco como um fator independente para parada cardíaca (OR 2,78; p = 0,019). A mortalidade hospitalar foi ligeiramente maior no G0, embora sem significância estatística. Segundo a análise de regressão de Cox, o número de fatores de risco não se associou com mortalidade. Os preditores de óbito em 1 ano de seguimento foram infarto do miocárdio com elevação do segmento ST (OR 1,05; p < 0,001) e fração de ejeção inferior a 50% (OR 2,34; p < 0,001). Conclusão: Embora o grupo sem fatores de risco fosse composto de pacientes mais jovens e com menos comorbidades, melhor função ventricular esquerda e coronariopatia menos extensa, a ausência de fatores de risco foi um preditor independente de parada cardíaca.

PURPOSE: Evaluation of maternal, obstetrics e neonatal features in both spontaneous preterm births (PTB) with or without preterm premature rupture of membranes (PPROM). METHODS: Retrospective study of single fetus pregnancies with PTB between 2003 and 2012. INCLUSION CRITERIA: PTB associated with ou without PPROM. Exclusion criterias: PTB by medical indication due to fetal/maternal disease and all non accessible or incomplete clinical files. Different characteristics were compared between two groups of PTB: spontaneous PTB without PPROM (sPTB) versusPPROM. Kolmogorov-Smirnov, Levene, χ2, t Student and Mann-Withney tests were used for statistical analysis. RESULTS: From 2,393 PTB of single fetus, 1,432 files were analysed, from which 596 were sPTB and 836 PPROM. The socioeconomic conditions were similar in both groups. Multiparity (50.7 versus 40.3%), personal history of previous PTB (20.8 versus10.2%), cervical length (18.2 versus27.2 mm), lower body index mass (23.4 versus 24.3 kg/m2) and higher infectious parameters (Protein C Reactive: 2.2 versus1.2 mg/L; Leukocytes: 13.3 versus 12.4 x109) were more frequent in PBTs (p<0,001). Neonatal outcomes, specially neurologic outcomes (4.7 versus2.8%, p<0,001), were worst in PBTs. CONCLUSION: PTB with or without PPROM has a complex etiology. From all evaluated features in our study, only maternal thinness, multiparity with a previous PTB, the cervical length and worst systemic infections parameters were significant in sPTB. This group also showed worst neonatal outcomes, specially on neurological outcomes.

OBJETIVO: Avaliação das caraterísticas maternas, obstétricas e neonatais nos partos pré-termo (PPT) associados ou não à rotura prematura de membranas pré-termo.MÉTODOS: Estudo retrospetivo de gestações de feto único, com um parto pré-termo, entre 2003 e 2012. Critérios de inclusão: a ocorrência de parto associado ou não à rotura prematura de membranas pré-termo. Critérios de exclusão: partos motivados por comorbidades fetal e/ou maternas (iatrogênicos); e processos não disponíveis ou incompletos para consulta. Foram comparadas caraterísticas entre os dois grupos de PPT: PPT espontâneo (PPTe)versusrotura prematura de membranas pré-termo (RPM-PT), tendo sido utilizados na análise estatística os testes Kolmogorov-Smirnov, Levene, χ2, t de Student e Mann-Withney.RESULTADOS: Dos 2.393 partos pré-termo de feto único, foram analisados 1.432, dos quais 596 foram espontâneos (PPTe) e 836 foram associados à RPM-PT. Das variáveis analisadas, os fatores socioeconômicos foram sobreponíveis em ambos os grupos. Foram mais frequentes no grupo PPTe (p<0,001) a multiparidade (50,7 versus40,3%), os antecedentes obstétricos de PPT (20,8 versus10,2%), o comprimento cervical (18,2 versus27,2 mm), o baixo índice de massa corpórea (IMC) (23,4 versus24,3 kg/m2) e a elevação dos marcadores infecciosos como a Proteína C reativa (2,2 versus1,2 mg/L) e os leucócitos (13,3 versus12,4x109). O desfecho neonatal, em termos de comorbilidade, foi mais adverso no grupo PPTe, sobretudo à custa de piores resultados neurológicos (4,7 versus2,8%, p<0,001).CONCLUSÕES: Os mecanismos etiológicos do PPT, com ou sem RPM-PT, são bastante complexos. Das várias caraterísticas analisadas no nosso estudo, apenas o baixo IMC, a multiparidade com PPT anterior, o comprimento cervical foram os piores parâmetros infeciosos que foram predominantes no grupo PPTe. Esse último grupo mostrou ainda piores resultados perinatais sobretudo neurologicamente.

PURPOSE: To compare obstetric outcomes of induced preterm twin births (under 32 weeks gestation) with those spontaneously conceived. METHODS: Prospective study of twin pregnancies (25 induced and 157 spontaneously conceived) developed over a period of 16 years in a tertiary obstetric center. Demographic factors, obstetric complications, gestational age at delivery, mode of delivery, birth weight and immediate newborn outcome were compared. RESULTS: The analysis of obstetrical complications concerning urinary or other infections, hypertensive disorders of pregnancy, gestational diabetes, fetal malformations, intrauterine fetal death, intrauterine growth restriction and intrauterine discordant growth reveal no significant statistical differences between the two groups. First trimester bleeding was higher in the induced group (24 versus 8.3%, p=0.029). The cesarean delivery rate was 52.2% in spontaneous gestations and 64% in induced gestations. Gestational age at delivery, birth weight, Apgar scores at first and fifth minutes, admissions to Neonatal Intensive Care Unit and puerperal complications show no statistically significant differences between the two groups. These results were independent of chorionicity and induction method. CONCLUSION: The mode of conception did not influence obstetric and neonatal outcomes. Although induced pregnancies have higher risk of first trimester bleeding, significant differences were not observed regarding other obstetric and puerperal complications and neonatal results.

PURPOSE: It was to analyse the most critical areas in Obstetrics and to suggest measures to reduce or avoid the situations most often involved in these disputes. METHODS: Obstetrics cases submitted to the Medico-legal Council since the creation of the National Institute of Legal Medicine and Forensic Sciences in 2001 until 2011 were evaluated. A comprehensive characterization, determination of absolute/relative frequencies, hypothesis of a linear trend over the years and the association between each parameter was done. RESULTS: The analysis has shown no significantly linear trend. The most common reasons for disputes were perinatal asphyxia (50%), traumatic injuries of the newborn (24%), maternal sequelae (19%) and issues related to prenatal diagnosis and/or obstetric ultrasound (5.4%). Perinatal asphyxia showed no significantly linear trend (p=0.58) and was usually related to perinatal deaths or permanent neurologic sequelae in newborn children. Traumatic injuries of the newborn, mostly related to instrumented deliveries, shoulder dystocia or vaginal delivery in breech presentation, has shown a significantly increased linear trend (p<0.001), especially related to instrumented deliveries. The delay/absence of cesarean section was the clinical procedure questioned in a significantly higher number of cases of perinatal asphyxia (68.7%) and of traumatic lesions of the newborn due to instrumented deliveries (20.5%). CONCLUSION: It is important to improve and correct theoretical/practical daily clinical performance in these highlighted areas, in order to reduce or even avoid situations that could end up in medico-legal litigations.

PURPOSE: To compare obstetric outcomes of induced preterm twin births (under 32 weeks gestation) with those spontaneously conceived. METHODS: Prospective study of twin pregnancies (25 induced and 157 spontaneously conceived) developed over a period of 16 years in a tertiary obstetric center. Demographic factors, obstetric complications, gestational age at delivery, mode of delivery, birth weight and immediate newborn outcome were compared. RESULTS: The analysis of obstetrical complications concerning urinary or other infections, hypertensive disorders of pregnancy, gestational diabetes, fetal malformations, intrauterine fetal death, intrauterine growth restriction and intrauterine discordant growth reveal no significant statistical differences between the two groups. First trimester bleeding was higher in the induced group (24 versus 8.3%, p=0.029). The cesarean delivery rate was 52.2% in spontaneous gestations and 64% in induced gestations. Gestational age at delivery, birth weight, Apgar scores at first and fifth minutes, admissions to Neonatal Intensive Care Unit and puerperal complications show no statistically significant differences between the two groups. These results were independent of chorionicity and induction method. CONCLUSION: The mode of conception did not influence obstetric and neonatal outcomes. Although induced pregnancies have higher risk of first trimester bleeding, significant differences were not observed regarding other obstetric and puerperal complications and neonatal results. .
OBJETIVO: Comparar os resultados obstétricos de gestações gemelares induzidas com as concebidas espontaneamente, em partos ocorridos antes da 32ª semana de idade gestacional. MÉTODOS: Estudo prospectivo de gestações gemelares (25 induzidas e 157 concebidas espontaneamente) desenvolvido durante um período de 16 anos num centro terciário de Obstetrícia. Foram comparados fatores demográficos, complicações obstétricas, idade gestacional no parto, tipo de parto, peso ao nascer e o outcome imediato do recém-nascido. RESULTADOS: A análise das seguintes complicações obstétricas: infecções urinárias ou outras, distúrbios hipertensivos da gravidez, diabetes gestacional, malformações fetais, morte fetal intrauterina, restrição de crescimento intrauterino e crescimento intrauterino discordante não revelou diferenças estatísticas significativas entre os dois grupos. No grupo das gestações induzidas, observou-se maior taxa de metrorragias do 1º trimestre (24 versus 8,3%, p=0,029). A taxa de cesariana foi de 52,2% nas gestações espontâneas e 64% nas gestações induzidas. Idade gestacional no parto, peso ao nascer, índice de Apgar no primeiro e quinto minutos, internamento em unidade de cuidados intensivos neonatal e complicações puerperais não apresentam diferenças estatisticamente significantes entre os dois grupos. Esses resultados foram independentes do tipo de placentação e método de indução. CONCLUSÃO: O modo de concepção não influenciou os resultados obstétricos e neonatais. Embora as gestações induzidas tenham maior risco de metrorragias do primeiro trimestre, não foram observadas diferenças significativas em relação a outras complicações obstétricas, complicações puerperais e em relação aos resultados neonatais. .

OBJETIVO: Foi analisar as áreas mais críticas em Obstetrícia e sugerir medidas para reduzir ou evitar as situações mais frequentemente envolvidas nessas disputas. MÉTODOS: Foram avaliados todos os casos relativos à Obstetrícia apresentados ao Conselho Médico-legal desde a criação do Instituto Nacional de Medicina Legal e Ciências Forenses em 2001, até 2011. Foi efetuada uma análise compreensiva, determinação de frequências absolutas/relativas, hipótese de linear trend ao longo dos anos e a associação entre os diversos parâmetros. RESULTADOS: As razões mais comuns para o litígio foram a asfixia perinatal (50%), as lesões traumáticas do recém-nascido (24%), as sequelas maternas (19%) e questões relacionadas com o diagnóstico pré-natal e/ou ecografia obstétrica (5,4%). A asfixia perinatal não teve qualquer tendência linear ao longo dos anos (p=0,58) e esteve geralmente relacionada a mortes perinatais ou sequelas neurológicas permanentes nos recém-nascidos. As lesões traumáticas do recém-nascido, principalmente relacionadas com partos instrumentados, distócia de ombros ou parto vaginal em apresentação pélvica, mostrou uma tendência linear de aumento significativo ao longo dos anos (p<0,001), especialmente relacionada com a instrumentação dos partos. O atraso/ausência de cesariana foi o procedimento clínico questionado num número significativamente maior de casos de asfixia perinatal (68,7%) e de lesões traumáticas do recém-nascido devido a partos instrumentados (20,5%). CONCLUSÃO: É importante melhorar e corrigir o desempenho teórico/prático da clínica diária nas áreas destacadas, a fim de reduzir ou mesmo evitar situações que poderão levar a litígio médico-legal em obstetrícia. .

PURPOSE: To evaluate the obstetric and perinatal outcomes evolution of triplet pregnancies. METHODS: A prospective observational study was conducted in triplet pregnancies delivered over 16 years in a tertiary obstetric center with differentiated perinatal support. Evaluation of demographic factors, obstetric complications, gestational age at delivery, mode of delivery, birth weight and immediate newborn outcome were done over a 16 years period. A global characterization of the sample was performed considering the listed parameters. Variables were categorized in three groups according to year of occurrence: 1996-2000, 2001-2006, 2007-2011, and all parameters were compared. RESULTS: Of the 33 triplets included, 72.7% resulted from induced pregnancies. All except one patient received prenatal corticosteroids and five received tocolytics. All women delivered prenatally and no significant differences were seen in the mean gestational age at delivery or birth weight towards time. There were three intrauterine fetal deaths. Neonatal immediate outcomes were not significantly different over the years. CONCLUSION: Despite remarkable progresses in perinatal and neonatal cares, no noticeable impact in triplet gestations' outcomes was seen, sustaining that triplets should be avoided due to their great risk of prematurity and neonatal morbidities, either by limiting the numbers of embryos transferred or by fetal reduction.

OBJETIVO: Avaliar a evolução obstétrica e os resultados perinatais das gestações triplas. MÉTODOS: Um estudo observacional prospectivo foi realizado em gestações triplas durante 16 anos num centro obstétrico terciário com apoio perinatal diferenciado. Foram realizadas avaliações dos fatores demográficos, de complicações obstétricas, da idade gestacional ao parto, do tipo de parto, peso do recém-nascido e resultado neonatal imediato por um período de 16 anos. A caracterização global da amostra foi realizada considerando os parâmetros listados. As variáveis foram divididas em três grupos de acordo com o ano de ocorrência: 1996-2000, 2001-2006, 2007-2011, e todos os parâmetros foram comparados. RESULTADOS: Das 33 gestações triplas incluídas, 72,7% resultaram de gravidezes induzidas. Exceto uma paciente, todas receberam corticosteroides pré-natal e cinco efetuaram tocolíticos. Todas as mulheres tiveram um parto pré-termo e não se observaram diferenças significativas na idade gestacional média ao parto nem no peso ao nascer ao longo do tempo. Houve três óbitos fetais. Os resultados neonatais imediatos não foram significativamente diferentes ao longo dos anos. CONCLUSÃO: Apesar dos avanços notáveis em cuidados perinatais e neonatais, nenhum impacto perceptível nos resultados de gestações triplas foi verificado. Essas gestações devem ser evitadas devido ao grande risco de prematuridade e morbilidade dos recém-nascidos, tanto por limitação do número de embriões transferidos como por redução fetal. .
