A Case of Abdominal Aortic Mobile Plaque Complicated by Mitochondrial Encephalomyopathy Treated with EVAR

Abstract

A 56-year-old man had hepercholesterolemia. A statin was prescribed by a nearby doctor. However, the oral administration was discontinued because of hypercreatine kinasemia. The patient was referred to our hospital because of continuous hepercreatine kinasemia. He had short stature, muscle weakness in both lower extremities, blepharoptosis, and left sensorineural hearing loss. As a result of detailed examination, mitochondrial encephalomyopathy was diagnosed according to the diagnostic criteria. Abdominal ultrasonography revealed a markedly mobile plaque in the abdominal aorta just above the inferior mesenteric artery (IMA). EVAR was performed because there was concern about the occurrence of embolism. In surgery, stent graft was opposed directly above the IMA bifurcation of the infrarenal abdominal aorta, and vascular echocardiography confirmed the disappearance of mobile plaque. The patient was discharged without complications such as embolism. We report a case of abdominal aortic mobile plaque complicated by mitochondrial encephalomyopathy treated with EVAR.
