Six-year-old conjoined twins Eva and Erika Sandoval made headlines back in December 2016 for the most incredible reason: The adorable girls from California underwent a 17-hour-long surgery at Lucile Packard Children’s Hospital Stanford to separate their bodies.
The twins were born joined at the sternum, diaphragm, liver, pelvis, and third leg.
The girls had only a 30% chance of survival at birth. But Aida, the twins’ mother, decided the risk of delivering Eva and Erika was more than worth it.
According to CNN, “The overall survival rate of conjoined twins is between 5 percent and 25 percent, with about 75 percent of surgical separations resulting in at least one twin surviving.”
Not only that, but surgeon Gary Hartman was particularly concerned about Erika because she was so much smaller than her sister.
“The more calories we gave her, the bigger Eva got,” he told Fox.
Watch what happened following the milestone surgery. It’s nothing short of miraculous, because these girls are thriving today.
