RESUMO
Perinatal hemolytic disease occurs secondary to a hemolytic phenomenon of immune origin resulting in fetal or neonatal anemia. A 38-year-old pregnant woman was referred to the Department of high risk Obstetrics, Hospital Universitario La Paz Madrid because of presenting a dichorionic diamniotic twin pregnancy spontaneously, pre-pregnancy diabetes poorly controlled and severe alloinmunization anti-D. Her first pregnancy ended in a normal delivery at term; in the period of 4 years, she has three newborn with 36, 34 and 40 weeks respectively, who die with a week of life. After that, two intrauterine fetal death occur at 26 weeks of gestation. The patient who is RhD negative, suffers anti-D inmunization with a antibody titration of 1/1024 with 14 weeks of gestation. Twelve plasmapheresis, eight doses of anti-D inmunoglobulins and intrauterine transfusions has been the treatment received. A severe anemia is found during the ultrasound control of the middLe cerebral artery peak systolic velocity in both twins since the 16th week. It remains stable thanks to the treatment. Finally at the 28th week of gestation, pregnancy is terminated with a cesarean section. The twins are born alive and premature, but with good general state. The measurement of the middle cerebral artery peak systolic velocity predicts moderate-severe fetal anemia cases, which are the most important in the clinical management because of the need of active treatment or finish the pregnancy.

Introducción: la transfusión fetomaterna masiva (TFM) es una entidad con una elevada morbilidad y mortalidad fetal, suele cursar con una disminución en la percepción de los movimientos fetales por parte de la madre, y la presencia de un patrón cardiotocográfico sinusoidal fetal, asociado a la anemia fetal. No obstante, ambas situaciones tienen muy baja especificidad. Se presenta un caso clínico con el objetivo de revisar la exactitud del patrón sinusoidal en el diagnóstico de anemia fetal. Materiales y metodos: se presenta el caso de una gestante de 36 semanas que fue atendida en el Hospital Universitario La Paz (complejo hospitalario de tercer nivel que forma parte del conjunto de hospitales públicos en España), en la que tras presentarse un patrón cardiotocográfico no tranquilizador, se realizó una inducción del parto en el que las pruebas habituales de bienestar fetal resultaron insuficientes para el diagnóstico de sufrimiento fetal. Tras un parto eutócico se comprobó la presencia de una anemia neonatal grave, comprobándose la presencia de un gran volumen de sangre fetal en la sangre materna mediante el test de Kleihauer Betke. Se hace una revisión de los artículos publicados en los últimos 10 años en las base de datos Medline vía PubMed, en español e inglés.Conclusión: la monitorización fetal intraparto podría ser útil en el diagnóstico de la hemorragia fetomaterna masiva, aunque se deben hacer estudios más amplios para determinar la exactitud diagnóstica...
Introduction: massive fetomaternal transfusion (MFT) is an entity having high fetal morbidity and mortality; it usually involves the mothers reduced perception of fetal movements and the presence of a cardiotocographic fetal sinusoidal rhythm, associated with fetal anemia. However, both situations have very low specificity. A clinical case is presented here to arouse interest in reviewing the precision of the sinusoidal rhythm when diagnosing fetal anemia. Materials and methods: the case of a 36-weeks pregnant mother is presented; she attended La Paz teaching hospital (a third-level hospital forming part of the Spanish public hospital system). After presenting a non-reassuring cardiotocographic heart rate pattern, birth was induced in which the usual fetal wellbeing tests proved insufficient for diagnosing fetal suffering. The presence of serious neonatal anemia was shown following a eutocic delivery, the Kleihauer-Betke test proving the presence of a large volume of fetal blood in the mothers blood. Articles published in both Spanish and English during the last 10 years in the Medline database were reviewed via PubMed. Conclusion: intradelivery fetal monitoring could be useful in diagnosing massive fetal-maternal hemorrhage, even though broader studies should be carried out for determining diagnostic precision...
