One Side Occlusion of Double Inferior Vena Cava

Abstract

A 47-year-old female was admitted to our hospital for her swelled lower legs and rapid getting weight. She was obese, and her arterial blood gas analysis showed hypoxia. CT and venography revealed a double inferior vena cava (IVC), with occlusion of its right side. The two cavae were jointed by the internal iliac anastomosis and the left renal vein. Perfusion lung scintigraphy revealed marginal perfusion defects. After the fibrinolysis therapy and heparin, she got better and was discharged.
