Abstract:
Persistent extrahepatic right umbilical vein without ductus venosus is a rare anomaly of systemic venous drainage and is reported to be associated with cardiac anomalies. We report the case of an 8-year-old boy diagnosed to have an ostium secundum atrial septal defect, in whom an abnormal vascular channel and its opening in the right atrium in close relationship to the inferior vena cava and coronary sinus opening was identified at operation. Post-operative evaluation of this vascular channel was diagnosed to be an extrahepatic persistent right umbilical vein.

The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
01:11Overview 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...

The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
