Renal artery stenting has recently been used to treat failures or complications of renal angioplasty. Although technical results and complication rates have been reported, clinical follow-up and long-term data are limited. The purpose of this study was to evaluate the midterm clinical efficacy and safety of Palmaz stents in rescuing renal artery angioplasty failures.

Palmaz stents were placed in 35 renal arteries of 33 patients (14 men and 19 women; 37-77 years old; mean age, 62.6 years old) for immediate angioplasty failure (29 arteries) or for recurrent stenosis after previous angioplasty (six arteries). Indications for treatment were hypertension alone (16 patients) or hypertension associated with renal failure (17 patients). Blood pressure, medication, and serum creatinine level were followed after stenting.

No residual stenosis was found immediately after stenting. Mean clinical follow-up was 13.4 months (range, 1-34 …
