ABSTRACT
Percutaneous transluminal angioplasty techniques have become the cornerstone of therapeutic strategy for renal artery stenosis. Occasionally, even after successful technical results, a decline in renal function may be noted in a subset of patients. Recently, Isles et al2 published a review of 10 studies, including 416 stent placement procedures in 379 patients treated for renal artery stenosis. Although technical success was high (96-100%), renal function improved in 26%, stabilized in 48% and deteriorated in 26% of the patients.
