Abstract:
A case is reported of inferior vena cava syndrome in a patient with extreme obesity (BMI: >70 kg/m(2)), treated at a public hospital. The inferior vena cava obstruction was diagnosed during an attempt at inferior vena cava filter percutaneous insertion, in prebariatric surgery period. The diagnosis occurred after a hepatic scintillography, and was confirmed with a femoral venography and celiac trunk arteriography. The patient underwent a biliopancreatic diversion-duodenal switch and has lost weight. A venography 7 months after the surgery did not show any inferior vena cava rechanneling evidence.

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 middle...

Veins of Thorax
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.
