Likud MK Oren Hazan was rushed to Rabin Medical Center Beilinson Campus Friday night after feeling ill.
His spokesman said that following standard check-ups, he was rushed into surgery overnight and was placed under full anesthesia.
The spokesman said that surgeons found that a disconnected vein which caused a large rush of blood was the source of the problem.
But Channel 10 reported that Hazan's spokesman reported inaccurate information, and the reason for his hospitalization was different.
A Beilinson statement said he was still hospitalized Saturday night, but not in the emergency room.
