Renal artery angioplasty and stenting is a common treatment for renal artery stenosis (RAS), offering good outcomes. However, some patients experience kidney function decline, possibly due to atheroembolism, necessitating further research into protective measures.

Area of Science:

  • Cardiovascular Medicine
  • Nephrology
  • Interventional Radiology

Background:

  • Renal artery stenosis (RAS) is increasingly diagnosed due to advanced imaging techniques.
  • RAS is common in patients with hypertension and other vascular diseases.
  • Renal angioplasty and stenting is a primary treatment for RAS.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of renal angioplasty and stenting for RAS.
  • To identify factors contributing to renal function deterioration post-procedure.
  • To explore the potential of protection devices in mitigating complications.

Main Methods:

  • Review of technical success, anatomical results, complication rates, and long-term patency of renal angioplasty and stenting.
  • Analysis of renal function (RF) and blood pressure (BP) changes before and after intervention.

  • Discussion of emerging techniques like renal angioplasty with protection devices.

    • Main Results:

    • Renal angioplasty and stenting demonstrates high technical and anatomical success rates with good long-term patency.
    • The procedure benefits many patients by preserving renal function and stabilizing blood pressure.
    • A significant minority (20-30%) experience renal function deterioration, with atheroembolism implicated.

    Conclusions:

    • Renal angioplasty and stenting is effective for RAS, but renal function decline remains a concern.
    • Renal angioplasty with protection devices shows promise for improving outcomes and may become a future standard.
    • Further research, including randomized trials, is needed to optimize techniques, devices, and indications.
