Doctors say the operation was carried out at the request of her family, in a "last chance" attempt to relieve pressure caused by brain haemorrhaging.
They say she remains in a deep coma, and the chances of her survival are minimal.
Ms Trintignant's boyfriend, rock singer Bertrand Cantat, is being questioned by police.
The 41-year-old actress suffered the injuries on Sunday at the Lithuanian hotel where the couple were staying.
Her family, including her film star father Jean-Louis Trintignant, has flown to Vilnius to be at her bedside.
Her 17-year-old son Roman, and her mother, film

Cantat, who is lead singer with French rock band Noir Desir, was taken to the same hospital on Sunday after heavy alcohol use, police say.
Investigator Juozas Kandzezauskas said police had started questioning him about what happened at the hotel.
Trintignant has appeared in dozens of films, most of them French. She was in Vilnius to make a TV film about the life of French author Colette, being directed by her mother.
