Prenatal Diagnosis of Interrupted Inferior Vena Cava with Azygos Continuation: A Case Report

Inferior vena cava (IVC) disruption with continuation of the azygos is a rare congenital vascular abnormality that can be detected prenatally via high-resolution ultrasound. We present a case of isolated discontinuation of IVC, diagnosed during a routine abnormal scan of the second trimester, confirmed by fetal echocardiography, with an uneventful neonatal outcome. In accordance with the literature, we discuss the diagnostic approach, clinical significance and long-term implications of this vascular variant. We want to emphasize the importance of recognizing this anomaly and differentiating isolated cases from those associated with other congenital malformations.
