In the Cooperative Study of Renovascular Hypertension, 2,719 renal arteriograms were performed. Initial studies were done in 2,374 patients, and 345 studies were done on a follow-up basis. The transfemoral catheter technique was used in 77% of the cases. There was a fatality rate of 0.11% and a nonfatal major complication rate of 1.2%. Most of the major complications involved hemorrhage, thrombosis, and renal injury. These did not appear to be related to the technique utilized.
