Prenatal phenotypes and outcomes of left-sided and duplicated inferior vena cava according to hepatic IVC continuity: a retrospective cohort study
This retrospective cohort study of 167 fetuses with left-sided or duplicated inferior vena cava reveals that while the interrupted hepatic IVC pattern (Type B) is strongly associated with complex cardiac anomalies and left isomerism, the drainage pattern itself does not independently predict fetal death, though it necessitates comprehensive prenatal assessment.
