Transplant patient Natasha Brown was today back in hospital after fears her body has rejected her new liver.
Although the teenager, of Banbury Road, Kidlington, is not seriously ill, doctors believe the organ she has had since May may be functioning abnormally.
Natasha BrownHer mother, Denise, said: "Two recent blood tests had shown there was a problem, but the doctors don't know how they are going to deal with it.
"It is likely that she will have to stay in hospital on a drip which every few hours will take over the function of her failing liver."
Natasha, 14, of Banbury Road, Kidlington, who suffered from autoimmune hepatitis, seemed to be recovering well from her eight-hour transplant operation at Birmingham Children's Hospital.
She had been on the transplant register for 84 days waiting for a suitable donor. Her new liver was donated by the family of a 13-year-old car crash victim. Since then, she has been physically fit and enjoying normal teenage life with her friends.
Recently, Oxford United chairman Firoz Kassam invited football-crazy Natasha to join him in the directors' box at the team's new home, the Kassam Stadium.
