Radionuclide venographic demonstration of portal and systemic collaterals in a case of complete IVC obstruction.
Radionuclide venography can be used to assess deep venous thrombosis and IVC obstruction. We present a case which, to our knowledge, has not been previously described, in which the entire liver and lungs are simultaneously visualized secondary to portal-caval and caval-systemic collaterals, respectively.
