title: Inferior caval venography in the assessment of renal carcinoma.
abstract: Inferior caval venography by a non-catheter technique was carried out in 30 cases of renal cell carcinoma. Occlusion of the renal vein was shown in 15 of these and occlusion of the inferior vena cava in a further three. Deformity of the vena cava by adjacent growth was found in nine instances. Renal arteriography was performed in 27 of these patients and the demonstration of the renal vein by this method has been compared with that of caval venography. The incidence of collateral veins on the arteriogram and the finding of impaired renal function as an index of renal vein occlusion has been discussed.
