London, Nov 19 One of the Bangaldeshi twins separated in a 25-hour operation in Australia has awoken from an induced coma.

Trishna and Krishna, who were rescued from an orphanage in Bangladesh two years ago and brought to Australia where they have been nursed back to health, were separated by a team of 16 surgeons, doctors and nurses at the Royal Children's Hospital in Melbourne.

Neurosurgeon Wirginia Maxiner said Trisha, who is almost three, was doing remarkably well, reports The Telegraph.

"She (Trishna) looks absolutely fantastic, I'm really, really pleased," Maxiner told 3AW radio.

She added: "I think we've succeeded. Once I see Krishna wake up. I looked at the scans and I was extremely reassured by the scans."

Her sister, Krishna, will be slowly brought out of the coma, Maixner said. Krishna will have a longer period of adjustment as the separation brought more changes to her body and brain's blood circulation.

The twins had been joined at the top of their heads and shared brain tissue and blood vessels. (ANI)
