GARCIA GUEVARA, Carlos et al. Umbilical vein draining directly into the right atrium: A case report. CorSalud [online]. 2021, vol.13, n.2, pp. 242-245.  Epub 01-Jun-2021. ISSN 2078-7170.

The ductus venosus agenesis is a rare condition associated with adverse perinatal outcomes. We present the case of a fetus of 23.4 weeks that was studied at the Department of Fetal Cardiology in the Cardiocentro Pediátrico William Soler. The four-chamber cross-sectional view echocardiogram showed cardiomegaly with a predominance of right chambers. After performing a longitudinal section of the fetus by color Doppler superimposed on the two-dimensional image, we could trace the course of the umbilical vein draining directly into the right atrium. The newborn underwent a CT scan and the presence of congenital digestive defects was diagnosed. In the case of suspected absence of ductus venosus it is important to determine the drainage variant, identify “microarrays”, and look for structural malformations and genetic diseases since prognosis will depend on all these factors.
