Hepatic veno-occlusive disease due to tacrolimus in a single-lung transplant patient.

Hepatic veno-occlusive disease is defined as nonthrombotic fibrous obliterative endophlebitis of small centrilobular hepatic venules. Clinically, patients present with elevated liver enzymes and a triad of jaundice, hepatomegaly and ascites. Although reported as a complication of other solid organ and stem cell transplantation, there have been no reported cases to date of veno-occlusive disease following lung transplantation. The present authors report a case of veno-occlusive disease following single-lung transplantation in a patient on a triple-drug immunosuppressive regimen composed of tacrolimus, mycophenolate mofetil and prednisone. The diagnosis was established by transjugular liver biopsy and by discontinuing tacrolimus; there was clinical regression of symptoms and serological return to baseline.
