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

The Jervell and Lange-Nielsen syndrome is an autosomal recessive trait characterized by deafness and electrocardiographic changes. These changes include prolongation of the QT interval and T-wave inversion. Treatment may include the use of beta-blockers to prevent the development of malignant ventricular arrhythmias and sudden death. We report a patient with this syndrome, who was receiving propranolol orally and who became hypoglycaemic during the preoperative fasting period prior to cochlear implantation.
