Liver transplant patient Natasha Brown has suffered a setback after her operation earlier this week.

The 13-year-old, who has autoimmune hepatitis and waited 84 days for a suitable organ donor, remains in intensive care after enduring eight hours of surgery on Tuesday.

Natasha with her parents Valves fitted to attach Natasha's new liver, during her operation at Birmingham Children's Hospital, have come loose, causing her blood pressure to soar. Her mother, Denise, said: "She's very quiet and very sore. We are all hoping she's going to be okay.

"We're praying it's going to be all right. The next five days will be a roller-coaster ride for the whole family."

Natasha, of Banbury Road, Kidlington, was diagnosed with autoimmune hepatitis in 1997.

The illness left her bloated, breathless and unable to play sport.

She suffered from constant nosebleeds and was forced to take 30 tablets every day in a bid to stop her own immune system from attacking her body.

The former Gosford Hill School pupil was excited about receiving the new liver, which should let her live an ordinary life.

Doctors are monitoring Natasha's condition. As soon as her condition stabilises, Mrs Brown hopes her daughter will be moved to a surgical ward to recover.
