Abstract
- Kidney cortex necrosis is a relatively rare cause of acute kidney injury and is characterized by complete or partial destruction of the renal cortex, but sparing of the medulla. Tranexamic acid has antifibrinolytic activity and is used to reduce bleeding. We report a rare case of kidney cortex necrosis caused by tranexamic acid. A 49-year-old woman complained of coughing up blood-tinged sputum. She had a history of bronchiectasis and was treated with tranexamic acid for 3 days. Four days after admission, she developed anuria and azotemia. Computerized tomography showed enhancement of the renal medulla, but not the bilateral renal cortex. The patient was treated with hemodialysis, and has since been maintained on hemodialysis for 6 months. Due to the development of kidney cortex necrosis in patients treated with tranexamic acid, all its potential complications should be considered.
