The U.S. State Department reported in a communique that U.S. Secretary of State Hillary Clinton on Wednesday left the New York hospital where she was being treated for a blood clot in the head.

Clinton was admitted to Presbyterian Hospital after a fainting spell while she was recovering from a stomach ailment, after which the blood clot was detected.

Clinton was released from Presbyterian Hospital several hours after undergoing tests at other medical facilities, a situation that caused temporary confusion among the media, which initially reported her initial trip to the other health centers to be her definitive release.

However, after the other tests, Clinton returned to the hospital for a time before being sent home later in the day, accompanied by her husband, former President Bill Clinton, and daughter Chelsea, who tweeted her thanks that her mother was once again at home and the medical team's assessment that she would recover completely.

The State Department said that Clinton - who had been followig a grueling schedule - wants to get back to work, adding that it will provide more information regarding her agenda "in the coming days."

The communique concluded by saying that Clinton and her family wanted to express their appreciation for the excellent care provided by the physicians, nurses and personnel at Presbyterian Hospital.

Photographs showed Clinton, dressed in a black coat and wearing sunglasses, walking down the hospital steps with the help of Chelsea and followed by former President Clinton.

The secretary was hospitalized for about 48 hours, and although doctors are still administering anticoagulants to her to help dissolve the clot they said earlier in the week that Clinton had sustained no neurological damage and is expected to recover completely.

The clot, located in a vein between the brain and the skull behind the right ear, has been linked to a concussion she suffered while she was recovering from a stomach infection.

The photographs taken on Wednesday are the first to show Clinton in public since Dec. 7, when her stomach problems began.

Because of her convalescence, her appearance was suspended before the congressional committee investigating the attack on the U.S. consulate in Benghazi, Libya, in which U.S. Ambassador Chris Stevens and three other Americans died.

Clinton's health situation raises doubts about her political future, particularly given that she developed another blood clot in her leg in 1998.

She will leave her post as secretary of state in January once the Senate confirms her replacement - Sen. John Kerry of Massachusetts - and many of her supporters are urging her to consider running for president again in 2016. EFE
