Revascularization in Renal Artery Stenosis: Current Treatments and Outlook

Abstract

Renal artery stenosis (RAS) refers to the reduction of lumen diameter of one or both renal arteries, which can cause multiple systemic lesions such as renovascular hypertension, ischemic nephropathy and flash pulmonary oedema. RAS has been attached importance with the improvement of diagnostic level. However, there are still no precise treatments for RAS. As for revascularization, its effect on RAS needs to be evaluated further, and it is also a hot research area. We analyzed the causes and mechanisms regarding the suboptimal effect of renal artery revascularization in some studies, summarized the strategies and neoadjuvant therapies that recently used to improve the effect of renal artery revascularization, with highlights on the importance of selection of patients for the treatment, providing evidence for guiding renal artery revascularization, and for choosing directions in research on patient selection for the treatment and the improvement of treatment effectiveness.
