Zsa Zsa Gabor remains in intensive care in hospital as doctors try to stabilise her and clear an infection that developed after her recent leg amputation, her husband said.
The actress was taken to Ronald Reagan UCLA Medical Centre after she began spitting up blood, Frederic Prinz von Anhalt said.
Zsa Zsa, whose 94th birthday is on Sunday, was also running a high fever.
"She's still hanging in there," her husband said. "They (doctors) are still working on her, trying to stabilise her and get her moved out of intensive care into a regular room."
The star hasn't recognised anyone since her leg amputation surgery last month, leading doctors to say she probably suffered a stroke, von Anhalt said. He said she was "sort of conscious".
"She doesn't know what is going on. She has no memories. It could come back but the doctor doesn't know yet," he added.
Doctors told him the only explanation for her failed memory was that she had a small stroke during the amputation.
Zsa Zsa was released from the hospital on January 22, a week after doctors removed most of her right leg because of gangrene. The Moulin Rouge actress broke her hip and had replacement surgery in July. She had been in hospital several times for swelling and clots before the amputation.
