Former motor racing champion Michael Schumacher's condition has improved slightly after an operation to relieve pressure on his brain, his doctors have said.
A new scan taken overnight showed signs that he was "better than yesterday", but he was still "not out of danger", doctors said.
The seven-time Formula 1 champion suffered head injuries on Sunday in a skiing accident in the French Alps.
He was put in a medically-induced coma.
An initial scan on Monday night showed "an improved situation" and indicated a window of opportunity for a second operation, doctors said.
The family took the "difficult decision" to give consent for the procedure, and doctors operated on Schumacher for about two hours.
A subsequent scan revealed a "slight improvement".
"We can't say he is out of danger but... we have gained a bit of time,'' said Dr Jean-Francois Payen. "The coming hours are crucial.
"All the family is very much aware that his state is still sensitive and anything can happen."
Doctors said it was impossible to give a prognosis for his condition for tomorrow, six months' or even a year's time.
