Transcatheter arterial embolization (TAE) effectively treated severely dysfunctional kidneys, normalizing blood pressure in hypertension cases and healing urinary fistulas. This minimally invasive procedure offers advantages over surgical nephrectomy for high-risk patients.

Area of Science:

  • Interventional Radiology
  • Nephrology
  • Vascular Surgery

Context:

  • Severely dysfunctional kidneys pose significant clinical challenges.
  • Conventional surgical nephrectomy may not be suitable for all patients, especially the elderly or those with comorbidities.
  • Complications include renal hypertension and refractory urinary fistulas.

Purpose:

  • To evaluate the efficacy and safety of Transcatheter Arterial Embolization (TAE) using pure ethanol for severely dysfunctional kidneys.
  • To assess TAE's impact on renal hypertension and urinary fistulas.
  • To compare TAE with traditional surgical nephrectomy.

Summary:

  • Transcatheter Arterial Embolization (TAE) with pure ethanol was performed on five patients with severely dysfunctional kidneys.

  • Successful complete embolization was achieved in all cases.
  • Kidney size significantly reduced post-TAE (average reduction rate: 72.61%).
  • Renal hypertension resolved in three patients, with normalized blood pressure and plasma renin activity sustained long-term.
  • Urinary fistulas healed in two patients.
  • TAE demonstrated advantages including being bloodless, noninvasive, technically simpler, and suitable for poor-risk patients.

    • Impact:

    • TAE offers a minimally invasive and effective alternative to nephrectomy for managing dysfunctional kidneys.
    • The procedure successfully addresses complications like renal hypertension and urinary fistulas.
    • TAE may lead to reduced juxtaglomerular cell function, contributing to blood pressure normalization.
    • Its applicability to high-risk patients expands treatment options in nephrology and interventional radiology.
