title: Study of the venous phase on renal angiography in cases of renal carcinoma.
abstract: The venous phase on renal angiography was studied in 65 cases of renal carcinoma. Opacification of the renal vein stem was observed in 33 cases (51%). The visualisation rate of the renal vein was lower in high stage than in low stage tumours but there was no difference between these groups if patients with tumour thrombus of the renal vein were excluded from the high stage group. Renal arteriovenous fistulas were observed in six cases (9%), in three of which tumour thrombus of the renal vein was also seen. The thrombus was discovered at operation in 14 of the 65 cases and it was in 10 of these that the striated vascular pattern was observed on renal angiography. Collateral veins were observed in 15 cases (23%), only five of which had tumour thrombus of the renal vein.
