First use of cryoplasty to treat in-stent renal artery restenosis

Abstract

Atherosclerotic renal artery stenosis is the most common cause of renovascular hypertension. Primary treatment of renal artery stenosis includes renal artery balloon angioplasty and, in some cases, renal artery stenting. However, in-stent restenosis occurs in 11% to 39% of patients thus treated. Herein, we report the case of a 76-year-old woman whose left-sided renal artery stenosis had been treated by means of renal artery stenting. She later presented at our institution with flash pulmonary edema that was caused by in-stent restenosis. We successfully treated the patient with cutting-balloon angioplasty and cryoplasty of the in-stent restenosis. To our knowledge, this is the 1st report of the use of cryotherapy to treat in-stent renal artery stenosis. © 2008 by the Texas Heart® Institute.
