Hemolysis-induced acute kidney injury following cardiac surgery: a case report and review of the literature.

ABSTRACT

Acute kidney injury is a common complication following cardiac surgery. Even small increases in creatinine levels are associated with increases in morbidity and mortality. Numerous factors such as hemolysis can contribute to the development of acute kidney injury after cardiac surgery. We present a rare case of severe hemolysis related to cardiopulmonary bypass resulting in kidney injury and requiring dialysis. The patient's renal function gradually recovered when hemolysis was improved. After follow-up for 3 months, his creatinine levels returned to normal. We discussed the pathogenesis of this hemolysis-related kidney dysfunction, the causes of hemolysis during cardiac surgery, and a new treatment option.
