Abstract
Ten hypertensive patients due to renal arterial stenosis were studied to determine the relationship between results of surgical revascularization and bilateral renal biopsy findings.
Seven patients including 5 with no intrarenal vascular lesion and 2 with slight arteriosclerosis, normal blood pressure was achieved after operation except in a case in whom surgery failed to repair his renal ischemia.
In 3 patients showing moderate to severe intrarenal small vessel disease, diastolic blood pressure was lowered to below 90mm. Hg, although one of them needed sometimes small doses of a hypotensive drug postoperatively.
On the basis of the present results, it is postulated that patients of renovascular hypertension even with intrarenal vascular changes, should be treated by surgical reconstruction of the stenotic renal artery whenever the procedure is adequately feasible.
