[Cholesterol embolism after percutaneous transluminal coronary angioplasty procedure: a case report].
A 68-year-old man with chest pain was treated under a diagnosis of angina pectoris based on coronary angiography by percutaneous transluminal coronary angioplasty including stent implantation performed by the femoral approach. About 1 month after intervention, his renal function deteriorated and purpura appeared on both feet, especially at the toe tips. He was treated under a tentative diagnosis of cholesterol embolism conservatively at the out-patient clinic. However, he was admitted by ambulance due to worsening renal failure 2 months later and died from multiple organ failure 2 weeks after admission. Autopsy examination identified cholesterol embolism due to crystal emboli in several organs. Cholesterol embolism rarely occurs after angiographic or interventional procedures, but is difficult to diagnose clinically and there is no established therapy. The number of intervention and angiography procedures is increasing, so the occurrence of embolism as a complication of these procedures might also increase.
