Fraser Health puts brain surgery online (not for the squeamish)
Obviously, the surgery wasn't happening live. The regional health authority invited people into the "virtual operating room" to follow a left frontal craniotomy to remove a tumour. The procedure was conducted by Dr. Mark Matishak, a neurosurgeon at Royal Columbian Hospital in New Westminster.
Fortunately, if you missed the "live" tweets, Fraser Health also posted video highlights of the operation on YouTube. #5 is my favourite clip. (Warning: graphic images.)
