Technical note on renal angioplasty and stenting: new developments that facilitate its performance

Technologic advances in percutaneous catheter-based therapy for renovascular occlusive disease have resulted in progressively miniaturized wires, balloon catheters, stents, and delivery systems. The technique of angioplasty and stenting of renal artery stenoses has been shown to be a safe and effective option for severe hypertension and ischemic nephropathy. Renal artery stenting, especially when performed with the newer lower-profile systems, can be performed with minimal morbidity and a reliably high degree of initial technical success. In this article, we describe our technique using a lower-profile platform of balloons and stents and review data supporting renal artery stenting.
