Doctors in the UK performed an emergency C-section on a 48-year-old crash victim who they mistakenly believed was pregnant.

Adele Barbour died at the hospital in January 2018 after she attempted to turn right off a road and slammed into an oncoming car in Nettleham, Lincolnshire, Metro UK reported Thursday.

Her scoliosis and spina bifida made her stomach appear swollen, leading paramedics to believe she was eight months pregnant, the outlet reported.

East Midlands Ambulance Service informed Lincoln County Hospital that they were bringing in a woman who appeared to be in her late 30s and pregnant — so medics immediately prepared to save the “mother” and “unborn child,” Lincolnshire Live reported.

With her life on the line, doctors operated on her, according to the report.

Coroner Marianne Johnson determined that their actions did not lead to her death.

“The evidence that I have heard is that the initial misdiagnosis [of pregnancy] did not cause or contribute to her death,” Johnson told Metro. “It appears all efforts were made in her care to try to save her but her injuries was so severe the outcome was inevitable.

“My conclusion is that Adele died as a result of a road traffic collision,” she said.

But Barbour’s sister Sarah-Jane Spence told the outlet the family is disappointed they were not notified about the C-section.

“On the day Adele was admitted, the doctor omitted to mention the C-section when she told us Adele was being moved to [the operating room], and neither did she tell us about it when she informed us of her death,” she said. “[The doctor] did not communicate the suggestion that she was pregnant or that they had carried out a C-section.

“‘The coroner’s officer rang the next day and asked me if I was aware they thought she was pregnant, and I said that I knew nothing about it.”

But Dr. Anthony Leetman, who produced a report obtained by Metro that investigated the paramedics’ and trauma team’s actions, wrote that Adele’s appearance led ambulance crews to believe she was pregnant.

“‘The crew pre-alerted the hospital quite correctly,” he said. “It was entirely reasonable to proceed to C-section. The trauma team can only proceed on the information that is presented to it. Given the information to the hospital by [the ambulance service], appropriate actions were taken.”

The injury to Barbour’s aorta, he wrote, was so severe that most people probably would have died before making it to the hospital.

“Sadly, she was very likely to die in any event,” Leetman added.
