Doctors said she needs to have her remaining leg amputated, but she decided not to do it.
The 94-year-old was admitted to Ronald Reagan UCLA Medical Center on Wednesday after blood flow to her left leg suddenly stopped. Most of Gabor's right leg was amputated in January because of an infection.
Her husband, Prince Frederic von Anhalt, said she's taking medication and has "a 50-50 chance" of surviving another year without surgery.
Gabor has been in and out of the hospital since she fell and broke her hip in July. She had a priest read her last rites in August.
