We report a case of superior vena cava obstruction in a child, which was pr
obably secondary to long-term central venous cannulation. The obstruction w
as asymptomatic preoperatively, but became evident during liver transplanta
tion, and complicated the intraoperative management. There is one other cas
e report of this occurring in an adult in similar circumstances, and we bel
ieve that ours is the first report of such a presentation in the paediatric
age group.
