Summary
A rare abnormal venous connection, persistent right umbilical vein, can bypass the liver and cause congenital malformations. This case details a unique venous drainage in a newborn with truncus arteriosus type II.
Area of Science:
- Medical Science
- Pediatric Cardiology
- Vascular Anatomy
Background:
- Persistent right umbilical vein is a rare congenital anomaly.
- Often associated with significant congenital malformations and hepatic bypass.
Observation:
- A newborn presented with severe systemic venous drainage abnormalities.
- The infant had a truncus arteriosus type II congenital heart defect.
Findings:
- Contrast injection revealed an unusual venous pathway.
- The anomalous vein coursed anterio-laterally through the right hemithorax.
Implications:
- This specific venous drainage may result from a persistent right umbilical vein.
- Understanding such anomalies is crucial for diagnosing complex congenital heart defects.
