All cases of inferior vena cava obstruction diagnosed at the Mayo Clinic between 1950 and 1973 were reviewed. Diagnosis was confirmed by surgery, phlebography, or postmortem examinations in 64 cases; the cause in 55 cases is described. Carcinoma of the kidney was the most common cause (31% pf cases). In nine cases, extensive laboratory investigation failed to reveal the cause of the process. These cases were considered to be primary inferior vena cava thrombosis and are reviewed in detail.
