Living donor liver transplantation for a patient with acute liver failure following thyroid storm: a case report.

BACKGROUND: Thyroid storm can be complicated by liver dysfunction, which may occasionally progress to acute liver failure. We herein report a case of acute liver failure following thyroid storm that was treated with living donor liver transplantation after resuscitation from cardiopulmonary arrest.

CASE REPORT: The patient was a woman in her 40 s who had been diagnosed with an abnormal thyroid function. She suffered from fatigue and vomiting, and was found to have consciousness disorder, a fever, and tachycardia with a neck mass. She was diagnosed with thyroid storm and was referred to our hospital. After arrival, she went into cardiopulmonary arrest and veno-arterial extracorporeal membrane oxygenation was initiated. In addition to treatment for thyroid storm with antithyroid drugs, steroids, and plasma exchange, extracorporeal life support was required for 5 days. However, despite improvements in her thyroid function, her liver function deteriorated. We planned living donor liver transplantation for acute liver failure after ensuring the recovery and control of the thyroid function following total thyroidectomy. The donor was her husband who donated the right lobe of his liver. Although she experienced acute cellular rejection after surgery, and other complications-including intra-abdominal hemorrhaging and ischemic changes in the intestine-her liver function and general condition gradually improved. One year after living donor liver transplantation, the patient was in a good condition with a normal liver function.

CONCLUSIONS: To our knowledge, this is the first report of living donor liver transplantation in a patient with acute liver failure following thyroid storm. Liver transplantation should be recognized as an effective treatment for acute liver failure following thyroid storm.
