Prenatal diagnosis of interrupted inferior vena cava as an isolated finding: a benign vascular malformation

We report two cases of interrupted inferior vena cava with azygous continua tion diagnosed as an isolated finding during routine prenatal scans. Visual ization of the venous vasculature of the abdomen and thorax in the mid-sagi ttal plane Jailed to visualize the segment of the inferior vena cava betwee n the kidneys and the liver. A vessel with venous flow was observed paralle l, adjacent and posterior to the aorta between the kidney and the right atr ium. This blood vessel connected with the superior vena cava. Axial Planes of the thorax confirmed the presence of two vessels running paravertebrally . A detailed ultrasound examination of the fetal anatomy failed to demonstr ate other anomalies. The neonatal course of both fetuses was uneventful. is olated interruption of the inferior vena cava can be a vascular malformatio n without known pathological consequences.
