The 94-year-old screen legend was rushed to a Los Angeles hospital for emergency stomach surgery on 17.05.11 and fell unconscious in the early hours of 18.05.11.
Her ninth husband Prince Frederic von Anhalt released a statement through publicist John Blanchette confirming Zsa Zsa`s grave condition, adding: "She had to have emergency surgery after she started bleeding in her stomach due to a feeding tube."
Zsa Zsa has been blighted with a string of recent health problems and was rushed to hospital earlier this month with severe pneumonia symptoms.
She also needed medical attention for high blood pressure after she became inconsolable over the death of her friend Dame Elizabeth Taylor in March.
The frail actress has also struggled with an infection in her left leg, and while doctors advised she should have the limb amputated - just a month after she lost part of her right leg - she refused the operation, leaving her with just a 50/50 chance of surviving for another year.
Frederic said: "Another big operation is a big risk for a woman who is 94 years old with high blood pressure.
"We don`t expect her to get better. She will be in bed for the rest of her life."
