[Urographic signs of thrombosis of the inferior vena cava and renal veins].

The case history of a 39 year old male with abdominal pain is described. Intravenous urography showed, during the late vascular period, collateral venous drainage around kidneys. Bilateral venous impressions on the ureters were observed at the excretory time. Inferior vena cavography and venous phase of selective renal arteriography confirmed the expected diagnosis of inferior vena cava thrombosis with bilateral renal vein involvement. Urographic signs of inferior vena cava thrombosis are discussed.
