Resumo Objetivo Recomenda-se o encaminhamento imediato de pacientes com fatores de risco para espectro placentário acreta (PAS, na sigla em inglês) para centros especializados, favorecendo assim o diagnóstico precoce e o manejo interdisciplinar. No entanto, erros diagnósticos são frequentes, mesmo em centros de referência (CRs). Buscou-se avaliar o desempenho do diagnóstico pré-natal para PAS em um hospital latino-americano. Métodos Um estudo descritivo retrospectivo incluindo pacientes encaminhados por suspeita de SAP foi realizado. Os dados dos exames de imagem do pré-natal foram comparados com os diagnósticos finais (intraoperatórios e/ou histológicos). Resultados Foram incluídos 162 pacientes no presente estudo. A idade gestacional mediana no momento da primeira ultrassonografia suspeita de PAS foi de 29 semanas, mas as pacientes chegaram ao CR de PAS com 34 semanas. A frequência de resultados falso-positivos nos hospitais de referência foi de 68,5%. Sessenta e nove pacientes foram operadas com base na suspeita de PAS com 35 semanas e houve 28,9% de falso-positivos no CR. Em 93 pacientes, o diagnóstico de PAS foi descartado no CR, com frequência de falso-negativos de 2,1%. Conclusão O diagnóstico pré-natal de PAS é melhor no CR. Entretanto, mesmo nestes centros, resultados falso-positivos são comuns; portanto, a confirmação intraoperatória do diagnóstico de SAP é essencial.

Abstract Objective The immediate referral of patients with risk factors for placenta accreta spectrum (PAS) to specialized centers is recommended, thus favoring an early diagnosis and an interdisciplinary management. However, diagnostic errors are frequent, even in referral centers (RCs). We sought to evaluate the performance of the prenatal diagnosis for PAS in a Latin American hospital. Methods A retrospective descriptive study including patients referred due to the suspicion of PAS was conducted. Data from the prenatal imaging studies were compared with the final diagnoses (intraoperative and/or histological). Results A total of 162 patients were included in the present study. The median gestational age at the time of the first PAS suspicious ultrasound was 29 weeks, but patients arrived at the PAS RC at 34 weeks. The frequency of false-positive results at referring hospitals was 68.5%. Sixty-nine patients underwent surgery based on the suspicion of PAS at 35 weeks, and there was a 28.9% false-positive rate at the RC. In 93 patients, the diagnosis of PAS was ruled out at the RC, with a 2.1% false-negative frequency. Conclusion The prenatal diagnosis of PAS is better at the RC. However, even in these centers, false-positive results are common; therefore, the intraoperative confirmation of the diagnosis of PAS is essential.

Abstract BACKGROUND: Adaptive changes occur in pregnancy, secondary to hormonal variations, one of which is alterations in the level of plasma lipids that aims to ensure adequate nutrition to the fetus. However, sometimes triglycerides reach such high levels that they could compromise maternal health. CLINICAL CASE: The case of a female patient with a history of familial hypertriglyceridemia, exacerbated by the physiological processes of pregnancy, is presented. It was managed intrahospitalary, followed by nutrition and endocrinology, in addition to the use of pharmacological treatment and plasmapheresis. CONCLUSIONS: The use of plasmapheresis was evaluated as a therapeutic measure, where it was found to be an equally effective method after 6 sessions of treatment, achieving a 70% reduction in serum levels of triglycerides, however it was not a definitive measure and it was necessary to end the pregnancy.

Resumen ANTECEDENTES: Durante el embarazo suceden cambios adaptativos, secundarios a las variaciones hormonales, como las alteraciones en la concentración de lípidos plasmáticos necesarias para garantizar la adecuada nutrición al feto. Algunas veces la concentración de triglicéridos sobrepasa los límites de tolerancia y ello pone en riesgo la salud de la madre. CASO CLÍNICO: Paciente con antecedente de un embarazo, hipertrigliceridemia familiar que se exacerbó por los procesos fisiológicos del embarazo. Se hospitalizó para tratarla y los especialistas en Nutrición y Endocrinología le indicaron fármacos y plasmaféresis. CONCLUSIONES: La plasmaféresis es un método efectivo después de seis sesiones de tratamiento con el que se logran reducir 70% las concentraciones séricas triglicéridos, aunque no fue una medida definitiva y se requirió finalizar el embarazo.
