Doctors said that Michael Schumacher showed “slight improvement” following a second brain operation in the wake of Sunday's skiing accident in the French Alps. Schumacher had been skiing with his 14-year-old son when he fell and hit his head, cracking his helmet in the process.
Despite the small, “surprising” signs of improvement, doctors were cautious to provide more of a prognosis. Schumacher remained in critical condition in a medically induced coma, and doctors weren't sure how long that might last.
“We cannot say he is out of danger,” Dr. Jean-Francois Payen said, who's head of the hospital's intensive care unit. “But we have gained a bit of time.”
Doctors said there were still extensive blood clots that couldn't be accessed through surgery, according to The New York Times.
The latest operation – at a hospital in Grenoble, France – removed a large blood clot from the left side of his brain, which removed some of the stress on Schumacher's brain. However, some of the bruising remained too deep, making it impossible to predict one way or the other.
“Things can change very quickly, in a bad way or a good way,” Payen said.
Schumacher retired from Formula One last year with 91 career victories and an unprecedented seven world titles.
