OMAHA, Neb. (AP) — Omaha doctors say they kept the body of a brain-dead woman functioning for nearly seven weeks so the baby she was carrying could survive.

The tiny boy, Angel, was delivered earlier this month at Methodist Women’s Hospital. His mother, 22-year-old Karla Perez, had collapsed at home in Waterloo in early February. Doctors discovered a brain bleed and determined that she’d suffered brain death. Her family agreed to keep Perez’s body alive.

Dr. Todd Lovgren told television station WOWT the fetus was just 22 weeks along and couldn’t survive outside of the womb, so “we were going to have to prolong Karla’s pregnancy as long as possible.”

On April 4 her condition worsened, and doctors performed a cesarean section.

Perez was pronounced dead, and her organs were donated to other people.
