Transcatheter therapy for the treatment of atherosclerotic renal artery stenosis

The preemptory challenge in this invited review was to provide a contemporary evidence-based analysis of how renal artery intervention effects renal function and hypertension while also addressing the efficacy in transplanted kidneys. The authors tailored the paper architecture in a way that provides a systematic review of the randomized and observational data relating to the impact of renal stenting in each of these clinical domains. When appropriate the aujthors include data from their experience with over 1 200 renal stent procedures. This contemporary literature review provides objective insight into the procedural risk and early outcomes following renal intervention based on observational study results. However, well-controlled randomized trials and standardization of interventional technique with or without embolic protection is desperately needed.
