Renal denervation in a patient with prior renal artery stenting

This is a case report of a 69‐year‐old female with treatment‐resistant severe arterial hypertension despite prior successful percutaneous intervention to both renal arteries for significant renal artery stenoses (stenting of the right and balloon angioplasty of the left renal artery). The office blood pressure was 221/108 mm Hg at baseline. Secondary hypertension was ruled out and catheter‐based renal denervation performed (distal to the stent in the right renal artery and in the usual fashion in the left renal artery) without complications. The office blood pressure decreased at 1‐ and 3‐month follow‐up to 185/93 mm Hg and 182/95 mm Hg, respectively. This case illustrates the feasibility and potential efficacy of catheter‐based renal denervation in patients with a renal artery stent, an important finding as persistent hypertension is common in patients despite successful renal artery stenting and currently available trials examining renal denervation have excluded patients with prior renal artery stents. © 2012 Wiley Periodicals, Inc.
