PHOENIX (April 2, 2025) – About two months after welcoming their four identical baby girls to the world, Rachel and Marco Vargas have returned home to Cranston, Rhode Island, after the babies were recently discharged from Banner – University Medical Center Phoenix.
The couple was eager to go home after a long and complex pregnancy journey in which they sought care from Dr. John Elliott, a renowned multiple birth specialist at Banner – University Medical Center Phoenix, who said the chances of a pregnancy and delivery like Rachel’s was potentially around one in 40 million.
“We’re so excited to start this new chapter of our lives with little Sofía, Philomena, Veronica and Isabel,” Rachel said. “While it hasn’t been an easy journey, we’re thankful that we came to Banner and Dr. Elliott for care, and we can’t wait to share the milestones that will come with raising our beautiful girls.”
Dr. Elliott, who is globally recognized for his decades of experience having delivered hundreds of complex high-order multiples, said he has never seen a pregnancy like Rachel’s in his career.
The first two babies shared the same amniotic sac and had a velamentous insertion of the umbilical cord, where the umbilical cord inserts into the fetal membranes instead of the placenta, which can result in a 30-40% risk of death to the fetuses. Two of the babies were diagnosed with twin-to-twin transfusion syndrome, or TTTS. This happens when identical twins sharing a placenta experience an uneven blood flow between them, causing one to give too much blood to the other. If untreated, TTTS can lead to low amniotic fluid and poor growth for one twin, and too much amniotic fluid and an enlarged heart for the other.
“With all the complications involved in Rachel’s pregnancy, we were very candid about the risks and potential outcomes, but we also underscored the importance of having a positive outlook,” Dr. Elliott said. “I believe that played an important role in her successful case, along with constant top-class medical care throughout their stay in Phoenix.”
Because the quadruplets were born early at 30 weeks gestation, they required meticulous care by a team of skilled neonatologists, nurses and respiratory therapists. They remained in the neonatal intensive care unit until they were healthy enough to leave the hospital in late March.
“It was such a privilege for our team to care for Rachel and her babies,” said Dr. Suma Rao, medical director of the neonatal ICU at Banner – University Medical Center Phoenix. “These kinds of pregnancies can be quite scary for the parents and family members, so we are thrilled that they are all back home now with their healthy girls.”
