Abstract:
We report a case of cholesterol crystal embolism (CCE) after endovascular aortic repair for abdominal aortic aneurysm (AAA). A 68-year-old man with AAA underwent endovascular aortic repair. He complained of left lower abdominal pain after the operation. Abdominal CT showed renal infarction on postoperative day 10. Renal dysfunction developed after postoperative day 17. A biopsy of the renal infarct lesion demonstrated characteristic cholesterol clefts in the small arteries. We diagnosed CCE. Steroid therapy was administered and the patient's condition improved remarkably. Diagnosis of CCE is difficult and its prognosis still remains poor. Therefore, we should keep this unusual complication in mind.
