Little Freddie Verschueren was delivered using the Ex-utero Intrapartum Treatment known as EXIT.
The procedure is performed on babies in the womb who have an obstruction in their airway which would stop them from breathing.
Freddie had a cyst on his tongue which was detected in a scan during his mum’s second trimester.
He weighed 6lbs 8oz at birth and was able to go home with his parents Anna and Peter Verschueren a healthy baby.
Anna said: “We’ve been incredibly impressed with the service we have had at St George’s, at every step it has been outstanding care.
“When we found out we needed to have the procedure we felt in such safe hands with the experts at St George’s. We never doubted their skill and advice.”
Professor Khalil added: “I am very grateful to the efforts by every member of our large team who ensured that we delivered the best care to Anna and Freddie. Saving babies’ lives and caring for the parents during challenging times is the most rewarding aspect of my job.”
Dr Richard Jennings, Group Chief Medical Officer for St George’s, Epsom and St Helier University Hospitals and Health Group, said: “St George’s is one of the few hospitals in the country that carries out this rare procedure and saves the lives of many babies.
“I am pleased to hear that Freddie is doing well thanks to our dedicated and skilled teams and everyone at St George’s wishes him and his family all the best for the future.”
