Renal Infarction in a Patient with Hyperhomocysteinemia

Abstract

A 62-year-old man was referred to our hospital due to acute-onset severe left lumbar pain. Computed tomography of the abdomen revealed a nonenhancing area in the left kidney with renal artery occlusion. Hyperhomocysteinemia, which is known as a risk factor of cardiovascular and thrombotic diseases, was also diagnosed. We performed percutaneous transluminal renal intervention using an aspiration catheter, and started the replacement therapy for folic acid and vitamin B deficiencies in addition to anticoagulant therapy. With improvement of blood perfusion in the left kidney, the patient was discharged after 15 days. In this patient with renal infarction, hyperhomocysteinemia may have been responsible.
