[Cholesterol embolism syndrome after coronary angiography]

Area of Science:

• Cardiovascular Medicine
• Nephrology
• Vascular Surgery

Background:

• Cholesterol crystal embolism (CCE) is a serious complication following invasive vascular procedures or anticoagulant therapy.
• It is an underdiagnosed condition, with diagnosis often occurring postmortem.
• CCE affects multiple organs, leading to significant morbidity and mortality.

Observation:

• The case involved a 66-year-old man who developed symptoms after coronary arteriography with PTCA and stent implantation.
• Clinical manifestations included acral necrosis, cyanosis, livedo racemosa, and acute irreversible renal failure.
• These symptoms are characteristic of cholesterol crystal embolism.

Findings:

• Cholesterol crystal embolization is a multiorgan disease and a severe iatrogenic complication.
• Key diagnostic signs include acral pain, nonhealing ulcerations, necrosis, livedo racemosa, and sudden renal failure.
• Organ biopsy is essential for definitive diagnosis of CCE.

Implications:

• This case highlights the importance of recognizing CCE in patients with a history of vascular procedures and suggestive symptoms.
• Increased awareness and diagnostic vigilance are needed to improve outcomes for this underdiagnosed disease.
• Prompt diagnosis and management may prevent irreversible organ damage and improve patient prognosis.
