Publicist John Blanchette says the 94-year-old Gabor will be released from the hospital Friday. She was admitted Wednesday after blood flow to her left leg suddenly stopped.
Most of Gabor's right leg was amputated in January because of gangrene.
Gabor's husband, Frederic Prinz von Anhalt, says the actress is taking medication and has "a 50-50 chance" of surviving for another year without surgery.
Gabor has been hospitalized repeatedly since July, when she broke her hip falling from bed.
She appeared in films ranging from "Moulin Rouge" in 1952 to "Queen of Outer Space" in 1958. She also appeared on TV specials, game shows, and guest-starred on various TV series, often playing herself and using her catchphrase - "dahlink" - meaning "darling."
