Brachytherapy for renal artery in-stent restenosis.

We describe a 66-year-old female who presented with recurrent acute pulmonary edema and uncontrolled hypertension. She was diagnosed with left renal artery stenosis and treated with angioplasty and stent placement. Her clinical status improved initially but symptoms recurred within 4 months. Further evaluation documented renal artery in-stent restenosis, which was successfully treated with cutting balloon angioplasty followed by brachytherapy. The feasibility of renal artery brachytherapy and short-term follow-up is presented. Copyright 2003 Wiley-Liss, Inc.
