Abstract:
We report a case of prenatally diagnosed asplenia syndrome complicated by an infracardiac type total anomalous pulmonary venous connection. Stenting the ductus venosus through the umbilical vein was unsuccessful owing to the persistence of the right umbilical vein. Umbilical veins can develop various anomalies. When the fetus is planned for catheter intervention immediately after birth, the umbilical vein structure should be evaluated at the prenatal stage.

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
