It can also occur during pregnancy. While calculating the estimated right ventricular systolic pressure (RVSP) from tricuspid regurgitation (TR) gradient, corrections have to be applied in cases of IVC plethora. Although the liver has a dual blood supply, the hepatic veins provide the sole route of egress for blood exiting the liver. The result says The inferior vena cava was abnormal in this study.

Radiologically, it is most appreciable on portovenous phase imaging on cross-sectional imaging. Liver dysfunction and corresponding clinical signs and symptoms typically manifest late in the disease process. Cirrhosis is the most common cause of diffuse intrahepatic venous outflow obstruction. Conclusions: Measurements of respiratory variation in IVC collapse in healthy volunteers are equivalent at the level of the left renal vein and at 2 cm caudal to the hepatic vein inlet. An IVC diameter greater than 20 mm is commonly regarded as an upper limit of normal, which is a noninvasive indication of increased RA pressure in patients with cardiac or renal disease [4]. 3.
