The world’s first patient to have brain surgery with live artificial intelligence assistance has successfully had his tumour removed.
Rhys Hibbert, a father-of-two from Bedfordshire, could have lost his sight without the operation, said surgeons at University College London Hospital.
The AI tool analysed a video feed of the operation as it happened and advised surgeons on how to avoid crucial but hidden vessels and nerves in the brain. It allowed them to safely remove as much of the tumour as possible.
“From a patient safety perspective, I can see absolutely the benefit. There are no road signs inside our head,” said Hibbert.
Until 18 months ago, 48-year-old Hibbert, a customer services manager, was fit and healthy, going on a two-mile walk every lunchtime.
It was on one of these walks that he fell unconscious and started fitting in the road.
A brain scan revealed he had an 11mm (0.433in) non-cancerous tumour growing on the pituitary gland – a marble-sized organ at the base of the skull.
The gland secretes vital hormones that help with processes like growth, metabolism and regulating blood pressure and temperature.
Crucially it sits very close to the carotid arteries which are vital vessels that supply blood to the brain, and the optic nerves that control vision.
As Hibbert’s tumour began to press on his optic nerves, it narrowed his peripheral vision.
