Twenty-eight patients with a tumor thrombus 914 in the inferior vena cava and 14 in the renal vein), among a series of 170 renal cell carcinoma patients receiving hospital treatment at the Gunma University during the period from 1961 to 1989, were explored for clinical features, with the results leading to the following conclusions: 1) There were 19 male and 9 female with respective mean ages of 62.1 and 54.4 years. 2) The disease was right-sided in 16 patients and left-sided in the other 12, but there were no striking left-to-right difference in tumor location. 3) The most frequent chief complaint was symptoms arising from the urinary tract. Among symptoms and sings occlusion of the inferior vena cava or renal vein, proteinuria was most frequent, being present in 56% of patients with clinical evidence of occlusion, followed by tortuosity of veins of the abdominal wall and edema in the lower extremities noted in 3 patients. 4) Selective renal arteriography demonstrated tumor hypervascularity in all 22 patients (except for one with a hypovascular tumor mass) and A-V shunt at a high percentage. Profuse striated vascular pattern representing arterialization of an extensive tumor thrombus was also noted, particularly with intra-caval involvement. Venacavography demonstrated neoplastic thrombi in the inferior vena cava as filling defects, thus proving the diagnosis. CT also provided diagnostic evidence of a tumor thrombus in all cases except for one in which it failed to detect a tumor thrombus in the renal vein preoperatively, with an accurate diagnosis rate of 100% for intra-caval tumor thrombi and 83% for tumor thrombi in the renal vein.(ABSTRACT TRUNCATED AT 250 WORDS)
