Blanchette said that Gabor underwent surgery at /*Ronald Reagan UCLA Medical Center*/ on Saturday to get multiple blood clots removed from her upper body. One of the clots was very close to her heart.
Gabor was hospitalized on Friday due to excessive bleeding and pain.
She broke her hip July 17, had hip replacement surgery and had just returned home from the hospital Wednesday after various setbacks.
Gabor appeared in numerous films and television shows in the 1950s and 1960s, but she has been confined to a wheelchair due to a 2002 car crash. She also suffered a stroke in 2005.
