Renal artery stenosis (RAS) can cause kidney failure and high blood pressure. Early diagnosis and revascularization (surgical or endovascular) can preserve kidney function in at-risk patients.

Area of Science:

  • Nephrology
  • Cardiovascular Medicine
  • Vascular Surgery

Background:

  • Atherosclerotic narrowing of renal arteries (renal artery stenosis) can lead to chronic renal ischemia, atheroembolism, and renovascular hypertension.
  • Ischemic renal disease is an increasingly recognized, potentially treatable cause of chronic renal failure, though its precise prevalence is undetermined due to a lack of population-based studies.
  • Patients with atherosclerotic renal disease (ARD), especially those with high-grade stenosis and systolic hypertension, face a very high risk of renal atrophy and failure.

Purpose of the Study:

  • To highlight the significance of atherosclerotic renal disease (ARD) as a treatable cause of chronic renal failure.
  • To emphasize the diagnostic clues for ARD in at-risk populations.
  • To advocate for renal revascularization as a treatment to preserve renal function.

Main Methods:

  • Diagnosis is typically confirmed by angiogram.
  • Clinical suspicion is raised in elderly patients with systemic atherosclerosis and hypertension, presenting with a rapid rise in serum creatinine and decreased renal length.
  • The study emphasizes clinical recognition and the benefits of intervention.

Main Results:

  • Medical management of ARD is associated with high mortality.
  • Renal revascularization (surgical or endovascular) has been reported to lead to clinical improvement.
  • Preservation of renal function is achievable in selected patients through revascularization.

Conclusions:

  • Atherosclerotic renal disease (ARD) is a critical condition that requires consideration in at-risk patients.
  • Early diagnosis and intervention, particularly renal revascularization, can significantly improve outcomes and preserve kidney function.
  • Revascularization offers a better prognosis compared to medical management alone for patients with ARD.
