US secretary of state Hillary Clinton has left New York-Presbyterian Hospital, three days after doctors discovered a blood clot in her head.
Mrs Clinton's medical team advised her last night that she was making good progress on all fronts and said they were confident she would make a full recovery.
Doctors had been treating Mrs Clinton (65) with blood thinners to dissolve a clot in a vein that runs through the space between the brain and the skull behind the right ear.
"She's eager to get back to the office," her spokesman said.
Mrs Clinton had been in the hospital since Sunday, when doctors discovered the clot on an MRI test during a follow-up exam stemming from concussion she suffered earlier in December.
"Grateful my Mom discharged from the hospital and is heading home," her daughter Chelsea said on Twitter. "Even more grateful her medical team confident she'll make a full recovery."
Earlier yesterday, the State Department said Mrs Clinton had been speaking by telephone with staff in Washington and reviewing paperwork in hospital.
"She's been quite active on the phone," said department spokeswoman Victoria Nuland.
The illness has raised questions about Mrs Clinton's political future and how her health might influence her decision about running for president in 2016.
She suffered from a blood clot in 1998, midway through her husband's second term as president, although that clot was located in a knee.
