An evaluation of the effects of renal artery stenting in renovascular hypertension.
Renal artery stenosis is a common cause (1-6%) of secondary hypertension. Renal artery stenting has recently been employed as an adjunct to antihypertensive medication. We evaluated 92 patients who underwent renal angiography of whom 30 were stented. There was a reduction (p < 0.01) in blood pressure immediately post renal artery stenting--systolic BP from 157 +/- 20 to 140 +/- 21 mmHg and diastolic BP from 81 +/- 13 to 72 +/- 12 mmHg was sustained at 6 months follow up (148 +/- 20/76 +/- 12 mmHg) in the outpatients' clinic. The amount of antihypertensive medication did not differ post stenting--2.7 +/- 1.2 pre vs 2.7 +/- 1.2 drugs post procedure. Renal artery stenting did not provide a 'cure' for any patient with atherosclerotic renovascular hypertension and until the results of randomized studies are known we believe use should be restricted.
