Liver transplant for Budd-Chiari syndrome caused by paroxysmal nocturnal hemoglobinuria.

OBJECTIVES

Paroxysmal nocturnal hemoglobinuria is a rare acquired nocturnal disorder of the hematopoietic stem cells. The major causes of associated morbidity and mortality are chronic intravascular hemolysis, pancytopenia, and venous thrombosis.

PATIENTS

We report on a 20-year-old man with advanced Budd-Chiari syndrome caused by paroxysmal nocturnal hemoglobinuria, who underwent an emergency liver transplant.

RESULTS

At the time of this writing, the patient has good primary hepatic function, and, although not receiving specific medication, shows no signs of pancytopenia. Anticoagulation with low-dose acetylsalicylic acid was initiated. Forty-eight months after the transplant, there are no signs of thromboembolic complications affecting the liver.

CONCLUSIONS

Liver transplant is an appropriate treatment for Budd-Chiari syndrome caused by paroxysmal nocturnal hemoglobinuria. Supplemented by long-term low-dose anticoagulation treatment, liver transplant is superior to other surgical options, particularly when liver disease is advanced.
