Smallest lung transplant: Operation was challenging
A four-year-old boy is the shortest person in the UK to have a successful lung transplant, doctors said.
Surgeons at Great Ormond Street Hospital in London carried out the transplant involving Mason Lewis, measuring 93cm (3ft) tall.
He received lungs which were 11cm (4.3in) long during an operation lasting about eight hours.
Doctor Paul Aurora, from the hospital, said Mason's size added to the complications of carrying out the operation.
