Answer

By necessity and function, the balance between the coagulation system and the fibrinolytic system is delicate and dynamic. Disorders that disrupt this balance can cause a situation in which IVC thrombus formation may occur.

The nephrotic syndrome is a classic example. Patients with this syndrome have urinary protein losses. Both renal vein thrombosis and IVCT have been described. The exact mechanism of the hypercoagulability of patients with the nephrotic syndrome has not been fully delineated. However, these patients have massive urinary protein loss, and diminished levels of antithrombin III have been observed.
