Michael Schumacher had a second surgery after a brain scan showed a slight sign of improvement, doctors said Tuesday, but they warned that the Formula One champion remained in critical condition from head injuries sustained in a skiing accident.
Schumacher, 44, who won a record seven Formula One titles before retiring, suffered the injuries Sunday when he fell and struck a rock while skiing in the French Alps.
His condition stabilized somewhat after the second surgery Monday night at Grenoble University Hospital in France, but he remained in a medically induced coma, the Associated Press reported.
Dr. Emmanuel Gay, the hospital's chief neurosurgeon, said a brain scan performed late Monday showed bruising "a little bit everywhere" in Schumacher's brain but also an unexpected easing of pressure.
"The brain scan was, I must say, surprising," Gay said.
During the two-hour surgery, a hematoma, or a swelling of clotted blood, was removed from Schumacher's brain and his intracranial pressure further decreased, Britain's Guardian newspaper reported on its website.
A fresh brain scan conducted Tuesday morning showed "signs ... of slight improvement," the Guardian quoted hospital director Jacqueline Hubert as saying.
