RESUMO

OBJECTIVE: To evaluate the association between Doppler patterns in fetuses with Down syndrome (DS) and their placental histopathologic findings. METHODS: A retrospective cross-sectional study was performed by collecting data from medical records of singleton pregnancies between January 2014 and January 2022, whose fetuses had a confirmed diagnosis of DS either prenatally or postnatally. Placental histopathology, maternal characteristics, and prenatal ultrasound (biometric parameters and umbilical artery [UA] Doppler) were evaluated. RESULTS: Of 69 eligible pregnant women, 61 met the inclusion and exclusion criteria. In the sample, 15 fetuses had an estimated fetal weight < 10th percentile for gestational age (GA) and were considered small for gestational age (SGA). Thirty-eight fetuses had increased resistance on the UA Doppler. Histologic changes were detected in 100% of the placentas, the most common being delayed villous maturation, alterations associated with poor fetal vascular perfusion, and villous dysmorphism. More than 50% of the placentas showed alterations related to placental insufficiency. We did not observe a statistically significant association between UA Doppler examination and placental alterations. All placentas analyzed in the SGA subgroup showed findings compatible with placental insufficiency. CONCLUSION: We found no statistically significant association between placental histopathologic findings and UA Doppler abnormalities in fetuses with DS. The placental alterations identified were delayed villous maturation, alterations associated with poor fetal vascular perfusion, and villous dysmorphism.

RESUMO

OBJECTIVE: To identify antenatal predictors of adverse perinatal outcomes in a population of preterm fetuses with early placental insufficiency diagnosed by Doppler abnormalities. METHOD: In this cross-sectional study of a cohort of singleton pregnant women diagnosed with early placental insufficiency, relationships between perinatal variables (arterial and venous Doppler, gestational age, birth weight, oligohydramnios, estimated fetal weight, and fetal weight z-scores) and major neonatal complications were analyzed by logistic regression. RESULTS: Two hundred sixty-five women were delivered, between 24 and 33 weeks gestation. The overall frequency of intact survival was 57.9% (n = 154). Gestational age thresholds for best prediction of survival was 27 + 6 weeks and for intact survival was 29 + 0 weeks gestation. Fetal weight and absent/reversed ductus venosus a-wave were the main predictors of survival in the regression model. When fetal weight was substituted for fetal weight z-score, ductus venosus abnormal Doppler predicted mortality and absent or reversed umbilical artery diastolic velocities predicted intact survival. CONCLUSIONS: This study illustrates the impact of gestational age and fetal weight on perinatal outcomes in early placental insufficiency, with well-defined thresholds. Gestational age and fetal weight, or a combination of fetal weight z-scores and fetal Doppler parameters, were the best predictors of intact survival in our sample.

RESUMO

Communicating an unfavorable diagnosis during prenatal care is a growing challenge in clinical practice, as more and more tests are being performed to screen for the main conditions affecting the pregnant woman and her fetus. The way patients receive and subsequently deal with bad news is directly influenced by how the news is communicated by the attending physician. Unfortunately, physicians receive little or no training in communicating bad news, and they generally feel quite uncomfortable about doing so. Although many physicians consider the saying that "there's no good way to break bad news" to be the truth, the maxim does not reflect the true picture. The scope of this article is to discuss, in light of the scientific literature and the experience of fetal medicine services, some recommendations that can help to deal with these difficult moments and improve patient care for the remainder of the pregnancy.

A comunicação de diagnósticos durante o pré-natal é um desafio crescente na prática clínica à medida que se realizam cada vez mais exames para o rastreio das principais patologias que acometem as gestantes e seus fetos. A recepção de uma má notícia e sua posterior elaboração pela paciente serão diretamente influenciadas pelo modo como ela foi comunicada pelo profissional assistente. Infelizmente, os médicos recebem pouco ou nenhum treinamento para transmitir más notícias e, em geral, sentem-se extremamente desconfortáveis com isso. Embora a máxima "não existe uma maneira boa de dar uma notícia ruim" seja admitida como verdade por muitos médicos, ela não é representativa da realidade. O objetivo deste artigo é discutir à luz da literatura científica e da prática em centros de medicina fetal algumas recomendações que podem facilitar a vivência desses momentos difíceis e melhorar o cuidado com os pacientes para o prosseguimento da gestação.
