Evolución cardiológica postnatal y factores asociados a la agenesia de ductus venoso de diagnóstico prenatal
Resumen: Introducción
la agenesia del ductus venoso es una anomalía infrecuente con pronóstico variable. Puede ir de hallazgo aislado a producir muerte fetal. Así mismo, puede asociarse a otras anomalías y síndromes genéticos.
Material y métodos
estudio descriptivo de 12 niños con diagnóstico prenatal de agenesia del ductus venoso. Se evaluó lugar de drenaje de vena umbilical, variables perinatales, obstétricas, otras anomalías asociadas y evolución.
Resultados
el 75% (9/12) presentaba drenaje extrahepático de vena umbilical; de ellos, el 44, 4% (4/9) presentó insuficiencia cardiaca fetal. Al nacimiento, un 50% (6/12) asociaba anomalías cardiacas estructurales y un 41, 6% (5/12) precisaron tratamiento médico. El 25% (3/12) asociaba síndromes genéticos. 25% (3/12) de niños fallecieron (100% con cardiopatía), y un tercio de los supervivientes (3/9) presentó anomalías estructurales cardiacas. El 50% (6/12) de madres tenían antecedente de aborto o muerte fetal intraútero previa, 25% (3/12) de embarazos fueron producto de reproducción asistida y 25% (3/12) de gestaciones múltiples.
Conclusiones
se halló una incidencia elevada de defectos estructurales cardiacos en niños con agenesia del ductus venoso. Son más usuales si el drenaje es extrahepático y en ellos hay mayor frecuencia de anomalías genéticas y mortalidad. Un porcentaje importante de pacientes precisan tratamiento perinatal; la evolución es satisfactoria en los supervivientes.

Introduction: The absence of ductus venosus is an uncommon condition with a variable prognosis, which can vary from an isolated finding to causing foetal death. Furthermore, it can also be associated with other genetic anomalies and syndromes. Material and method: A descriptive study was conducted on 12 children with a prenatal diagnosis of absence of ductus venosus. An evaluation was made of the umbilical vein drainage site, perinatal and obstetric variables, other associated anomalies, and the outcomes. Results: Extra-hepatic drainage of the umbilical vein was observed in 75% (9/12) of cases, of which 44.4% (4/9) had foetal heart failure. At birth, 50% (6/12) were associated with cardiac structure anomalies, and 41.6% (5/12) required medical treatment. Genetic syndromes were detected in 25% (3/12) of cases. There were 25% (3/12) deaths (100% with heart disease), and one-third (3/9) of the survivors had cardiac structure anomalies. A history of abortion or previous intrauterine death was recorded in 50% (6/12) of the mothers, and in 25% (3/12) the pregnancies were the result of assisted reproduction, and 25% (3/12) multiple gestations. Conclusions: An elevated incidence of cardiac structure defects is found in children with absence of ductus venosus. They are more common if the drainage is extrahepatic, and within those, there is a higher frequency of genetic anomalies and death. A significant percentage of patients require perinatal treatment: The outcome is satisfactory in the survivors.
