title: Renal artery stenosis in hypertensive diabetic patients.
abstract: The prevalence of secondary forms of hypertension in diabetes is unknown. One hundred and five of 465 patients randomly selected from a diabetic clinic population were found to be hypertensive. Hypertensive patients aged less than 70 years were screened for renal artery stenosis using intravenous digital subtraction angiography. Two angiograms were technically unsatisfactory. All 18 insulin-dependent patients successfully screened had normal renal arteriograms. Five of 24 non-insulin-dependent patients had unilateral renal artery stenosis but functional tests did not clearly suggest that renal artery stenosis was causing the hypertension in these cases. No patient was referred for surgery or angioplasty. We conclude that renal artery stenosis is common in hypertensive non-insulin-dependent diabetics but may not, in many cases, be the cause of the hypertension. The criteria for investigating diabetic hypertensives for renal artery stenosis should be no different from those used in the general hypertensive population.
