Selective right renal arteriography confirmed a perforation in the proximal right main renal artery, approximately 3 cm from the ostium (Fig. 2A). Gore & Associates, Flagstaff, AZ) was placed across the perforation site in the right renal artery (Fig. 2B). Subsequent angiography showed good blood flow across the stented segment and restoration of distal flow (Fig. 2C).
