Purpose. To determine the usefulness of renal angiography in patients
that underwent coronary angiography because of clinically suspected co
ronary artery disease. Methods. Selective arteriography of the renal a
rteries was performed in 205 patients (mean age 60 +/- 8 years; 80% ma
les) at the time after coronary angiography with the use of right coro
nary Judkins catheter. Results. Two hundred renal angiographies were j
udged technically adequate. Average additional fluoroscopy time was 3
+/- 2 min and 30 +/- 8 ml of additional contrast medium was used. Coro
nary artery disease (greater than or equal to 50% narrowing) was found
in 158 (79%). Renal arterial disease was found in 17 (8.5%) patients.
Reduction in lumen diameter was < 50% in 11 patients (5.5%) including
3 patients with bilateral stenosis, and greater than or equal to 50%
in 6 patients (3%). The only clinical variable associated with renal a
rtery stenosis was peripheral vascular disease. Conclusion. There is n
o justification for doing routinely renal angiography for patients und
ergoing coronary arteriography because the prevalence of severe renal
artery stenosis is low.
