Atherosclerotic renal artery stenosis: Current status

摘要

Atherosclerotic renal artery stenosis (ARAS) remains a major cause of secondary hypertension and renal failure. Randomized, prospective trials show that medical treatment should constitute the main therapeutic approach in ARAS. Regardless of intensive treatment and adequate blood pressure control, however, renal and extra-renal complications are not uncommon. Yet, the precise mechanisms, accurate detection, and optimal treatment in ARAS remain elusive. Strategies oriented to early detection and targeting these pathogenic pathways might prevent development of clinical endpoints. Here, we review the results of recent clinical trials, current understanding of the pathogenic mechanisms, novel imaging techniques to assess renal damage in ARAS, and treatment options.
