Cholesterol crystal embolism, often iatrogenic, can cause multiorgan syndrome in high-risk patients. This condition leads to obliterating inflammation and high mortality rates, underscoring the need for awareness.

Area of Science:

  • Nephrology
  • Cardiovascular Medicine
  • Pathology

Background:

  • Cholesterol crystal embolism (CCE) is a serious complication, often triggered by medical procedures like angiography.
  • Patients with pre-existing cardiovascular disease risk factors are particularly susceptible.

Observation:

  • A 73-year-old woman with diabetes and hypertension presented with acute renal failure and ischemic changes in her feet post-angiogram.
  • Clinical findings included severe renal dysfunction, proteinuria, eosinophilia, and hypocomplementemia.

Findings:

  • Renal and skin biopsies confirmed cholesterol crystal emboli obstructing small arteries, leading to inflammatory reactions.
  • Despite treatment, renal function did not recover, necessitating chronic dialysis.

Implications:

  • CCE is a potentially fatal iatrogenic condition associated with significant morbidity and mortality.
  • Early recognition and management of risk factors are crucial for preventing CCE in vulnerable populations.
