ABSTRACT

La vena cava inferior (VCI) está constituida por tres segmentos de diferente origen embriológico. De su mala fusión, surge un amplio espectro de anomalías. La prevalencia de anomalías de la VCI es de 0,07-8,7% de la población. Generalmente, se diagnostica como hallazgo incidental en la vida adulta. Representa el 5-9,5% de las trombosis venosas profundas idiopáticas en menores de 30 años sin factores de riesgo asociados. Se presenta a una recién nacida a término con diagnóstico prenatal de ascitis en la semana 20 de gestación. Se diagnosticó, mediante angiotomografía abdominal, la agenesia de VCI. El tratamiento de pacientes con agenesia de la VCI se basa en el manejo de las complicaciones. Debido al mayor riesgo que presentan de sufrir un evento trombótico, se debe considerar la profilaxis antitrombótica a largo plazo. Se recomienda iniciar profilaxis anticoagulante en la pubertad.


Inferior Vena Cava (IVC) is composed of three segments from different embryological origin. Its lack of fusion originates a wide spectrum of anomalies of the IVC. These malformations are present in 0.07-8.7% of the population. It is generally diagnosed as an incidental finding in adult life. It represents between 5 and 9.5% of idiopathic deep vein thrombosis in patients younger than 30 years old without associated risk factors. We present a case of a term newborn with prenatal diagnosis of ascites during the 20th week of gestation. IVC Agenesis was diagnosed with the use of abdominal angiotomography. The treatment of patients with IVC Agenesis is based on the management of its complications. Due to the increased thrombotic risk of these patients, we should consider lifelong anticoagulation. We suggest initiating it during puberty.
