dr sanjay has abandoned his journalistic duties to scrub up and perform brain surgery on a teenager in an overstretched hospital in nepal .
the neurosurgeon , who is in kathmandu to cover the aftermath of saturday 's deadly earthquake , performed a craniotomy on the 15-year-old girl , sandhya chalise , after a wall of her family 's home fell on her as she collected water outside .
sandhya , who lives in a more remote area of the country , only reached kathmandu 's bir hospital two days after the 7.8-magnitude quake and by that point , blood had collected in the top of her brain , cnn reported .
