Atheromatous renal disease, often overlooked, causes severe renal failure through artery stenosis and cholesterol embolism. Early diagnosis via angiography and biopsy is crucial for timely intervention and better outcomes.

Area of Science:

  • Nephrology
  • Cardiovascular Medicine
  • Pathology

Background:

  • Atherosclerosis is a significant risk factor for cardiovascular disease.
  • Renal failure can be a consequence of systemic vascular disease.
  • The role of atheromatous disease in renal failure is often underestimated.

Purpose of the Study:

  • To investigate the incidence and characteristics of atheromatous renal disease.
  • To highlight the diagnostic challenges and therapeutic implications of this condition.

Main Methods:

  • Retrospective analysis of 32 patients with renal failure and atheromatous renal disease over 12 years.
  • Evaluation included clinical data, hypertension history, and renal function markers (serum creatinine).
  • Diagnostic procedures involved angiography and renal biopsy in selected cases.

Main Results:

  • Atheromatous renal disease was the primary cause of renal insufficiency in 22 cases, mainly due to renal artery stenosis.
  • Cholesterol crystal embolism was confirmed in renal biopsies and clinically in additional cases.
  • Complex intrarenal lesions and progression of stenoses were observed, often precluding surgical or interventional treatment.

Conclusions:

  • Atheromatous renal disease is a frequent, yet overlooked, cause of chronic renal insufficiency.
  • The condition involves both renal artery stenosis and intrarenal vascular pathology, including cholesterol embolism.
  • Early diagnosis through angiography and biopsy is recommended before advanced complications arise, enabling potential surgical intervention.
