Treatment of renovascular hypertension using stent implantation in an elderly patient with NIDDM.
A 70-year-old man with NIDDM was diagnosed as having renovascular hypertension (RVH), based on a stenosis of the ostial portion of the left renal artery with markedly elevated plasma renin activity (PRA) in both the left renal vein and the peripheral blood, and positive captopril tests. After percutaneous transluminal renal angioplasty (PTRA), his blood pressure (BP) and PRA normalized. However, since restenosis occurred three months later, stent therapy was applied, and consequently BP and PRA normalized immediately after this procedure. During the one-year follow-up, side effects have not been noted. We propose that stent therapy may be feasible for ostial renal artery stenosis in elderly diabetic patients.
