title: Occlusion of inferior vena cava--features by radionuclide venography.
abstract: Six adults with inferior vena caval obstruction are presented. Three were the results of surgical intervention, two were secondary to large thrombi, and one was due to pressure from a large renal-cell carcinoma and adjacent nodes. All underwent a modified approach of radionuclide venography, using a moderately large volume of sodium pertechnetate. Features characteristic of inferior vena caval obstruction were demonstrated in five of the six patients, and these various features are described and discussed.
