Los Angeles (CNN) -- Zsa Zsa Gabor's doctors took "one last shot" at saving the ailing actress' leg with powerful antibiotics her publicist said Monday afternoon.
If the newest treatment at Ronald Reagan UCLA Medical Center does not heal a "very deep" lesion in her lower leg, it will be amputated below the knee, according to spokesman John Blanchette.
"She has to be on very strong antibiotics for the next few days and then they will decide what kind of operation to go ahead with," Gabor's husband, Prince Frederic Von Anhalt, told HLN's "The Joy Behar Show" Monday.
Gabor, whose 94th birthday is next month, has not been told that amputation is a possibility, Von Anhalt said.
"I'm not going to tell my wife that she probably could lose her leg," he said. "She's going to get a heart attack."

Doctors recommended that Gabor check into the hospital before Christmas, he said, but she didn't want to go.
"She was crying and begged me 'Please don't bring me to the hospital over the holidays,'" he said.
Her condition worsened in recent days as gangrene set in, he said. "It smells already bad,"
In November, Gabor was hospitalized for a swollen leg, her husband said at the time. Paramedics initially suspected Gabor suffered from a blood clot in her left leg, but an emergency room doctor at Ronald Reagan UCLA Medical Center later determined she had an infection, according to Von Anhalt.
Gabor has been frail and "pretty much confined to a wheelchair" since a 2002 car accident, Von Anhalt has said. The crash happened when the car in which she was riding with her hairdresser slammed into a light pole on Sunset Boulevard in Los Angeles.
The Hungarian-born actress, the second of the three celebrated Gabor sisters, is most famous for her many marriages. Among her husbands was Oscar-winning actor George Sanders.
Her more prominent films include John Huston's 1952 Toulouse-Lautrec biopic, "Moulin Rouge;" "The Story of Three Loves" in 1953; "The Girl in the Kremlin" in 1957; and Orson Welles' 1958 classic, "Touch of Evil."
