Conjoined twins joined at the abdomen and sharing a liver are extraordinarily rare—occurring in only about one in every 200,000 births. Dr. Jose Iglesias, head of pediatric surgery at Cook Children’s Hospital, explains that only five to eight sets of conjoined twins survive each year worldwide, underscoring just how uncommon their case truly was.
The parents learned they were expecting conjoined twins at just 10 weeks into the pregnancy. What began as joyful anticipation quickly shifted into shock, fear, and uncertainty. The mother, Arciniega, admitted she could never have imagined expecting twins—let alone conjoined twins. Despite the emotional weight, her pregnancy progressed smoothly, apart from frequent visits to specialists across the state.
Conjoined twins often face overwhelming medical complications, and many do not survive gestation or die shortly after birth. Fortunately, scans revealed that the girls—JamieLynn and AmieLynn—each had their own hearts and heart sacs. This crucial detail not only increased their chances of survival but also made future separation possible.

The twins were delivered by cesarean section at 34 weeks on October 3, 2022, at Texas Health Fort Worth. Though stable in the NICU, they were not developing evenly because they shared a blood supply. One twin was effectively “stealing groceries” from the other, as Dr. Barber described. AmieLynn also began showing early signs of scoliosis.
As they grew, feeding and positioning became more difficult. Their closeness meant their hearts—and bodies—were pressing together more tightly with time. Doctors determined that separation would need to happen when the girls were nearly four months old.
The procedure carried immense risk. The liver’s dense network of blood vessels made bleeding a major concern, and the chance of infection lingered long after surgery. Surgeons also didn’t know how the girls’ hearts would respond to being positioned on their backs for the very first time.

In the operating room, a massive medical team assembled—three anesthesiologists, four pediatric surgeons, two plastic surgeons, and dozens of specialists. After hours of careful preparation, they opened the abdominal wall and meticulously divided the lower sternum and the shared liver.
At 3 p.m., the long-awaited update arrived: JamieLynn and AmieLynn had been successfully separated. The room erupted in tears, applause, and overwhelming relief as the family learned both babies were breathing peacefully on their backs—something they had never done before.
Recovery would be slow and would require a broad team of therapists: physical, occupational, speech, and nutritional experts. Doctors remained cautiously optimistic as they guided the girls through each step of healing.

Today, the twins are thriving like any other children—energetic, joyful, and uniquely themselves. Their parents share their journey on Instagram, proudly noting how different their personalities have become. “Aime is gentle and kind—you can see it in her eyes,” their father said. “And Jamie—she’s our little firecracker.”
Their remarkable story joins the growing list of conjoined twin miracles—children given a second chance at life through courage, expertise, and extraordinary medical teamwork.
