We report a case of successful pregnancy in a 22-year-old primigravida who became pregnant 19 months after orthotopic liver transplantation for end-stage liver dysfunction caused by Wilson disease. The mother continued immunosuppressive therapy (tacrolimus) during the pregnancy. No complications were observed. Labour started spontaneously at 40th week's gestation. As a result the healthy male infant weighing 3900 g was born. Patient and the baby were discharged from hospital, both in good condition, on the fifth day after delivery.
