Clinical outcomes of renal cholesterol crystal embolization

Area of Science:

• Cardiovascular Medicine
• Nephrology
• Pathology

Background:

• Cholesterol crystal embolization (CCE) is an increasingly recognized clinical entity.
• CCE typically affects elderly men, often following angiographic procedures or vascular surgery.
• The clinical presentation of CCE is diverse.

Observation:

• This report describes three patients who developed systemic cholesterol embolic disease.
• All three patients experienced varying degrees of renal failure.
• The onset of CCE and renal failure occurred after coronary angiographic interventions.

Findings:

• Systemic cholesterol embolization can manifest with significant renal impairment.
• Coronary angiography is a potential trigger for cholesterol crystal embolization.
• The severity of renal failure in CCE can be variable.

Implications:

• Increased awareness of CCE is crucial for early diagnosis and management.
• Nephrologists and cardiologists should consider CCE in patients with unexplained renal failure post-angiography.
• Further research into preventative strategies and treatment for CCE is warranted.
