  • Abstract
  • Look Inside

A 64-year-old male was admitted with renal failure which had developed 3 weeks after percutaneous trans-luminal angioplasty. Examination of peripheral bloodrevealed eosinophilia. Abdominal computerized tomo-graphy disclosed atherosclerotic changes at the site of bifacation of the renal artery and anuerysmal changes at the distal part. Suspecting cholesterol atheroem-bolism, renal biopsy was performed, revealing numerous occlusions of the artery with cholesterol emboli. Two months later the patient who was kept on maintenance hemodialysis, underwent an operation on the aneurysm in the abdonimal aorta. The renal function gradually improved on continuation of the maintenance dialysis.The patients was released from the dialysis 6 month later. Thus, cholesterol atheroembolism sometimes occurs 3 weeks after angioplasty without any symptoms and signs on the skin. and it should be kept in mind as a possible cause of acute renal failure. Histological examination including renal biopsy is a useful method for the diagnosis of cholesterol embolism. This was a rare cases in which impaired renal function was im-proved by long-term treatment to such a degree that hemodialysis was able to be discontinued.
