Atherosclerotic Renal Artery Stenosis

Renal artery stenosis is usually caused by atherosclerosis.

In some cases, it can by caused by renovascular hypertension.

Renal artery atherosclerosis is more likely to occur in older patients with risk factors for vascular disease.


The focus of managing atherosclerotic renal artery stenosis is the control hypertension and preserve renal function while reducing renal and cardiovascular outcomes in the long-term.

Treatment can include surgical reconstruction, revascularization without or with stenting, and medical therapy.

Individuals with renal stenosis have a variety of co-morbid disorders, including:

  • abdominal aortic aneurism;
  • refractory hypertension;
  • hypertension combined with diabetes;
  • conditions requiring dialysis chronic kidney disease;
  • peripheral artery disease.

Rental artery stenosis has become more common with the amount of angioplasty-stenting procedures increasing yearly. Over the last decade, the placement of a stent during angioplasty has become the new standard, improving rates of technical success.

There is not enough evidence to determine if this intervention has greater clinical benefits, such as improved renal function or blood pressure management, than medical therapy.
