Nov. 20, 2017 -- After 485 days at Children's Hospital of Philadelphia (CHOP), formerly conjoined twins, Erin and Abby Delaney, were discharged to return home to North Carolina, just in time for Thanksgiving.

Abby and Erin were born in CHOP's Garbose Family Special Delivery Unit on July 24, 2016, 10 weeks premature and joined at the top of their heads. On Tuesday, June 6, a multidisciplinary team of approximately 30 members successfully completed the separation of the then 10-month-old twins. The surgery, co-led by neurosurgeon Gregory Heuer, MD, PhD, and plastic surgeon Jesse Taylor, MD, lasted about 11 hours. It was the 24th time that surgeons at CHOP have separated a pair of conjoined twins, but the first craniopagus (joined at the head and the least common) pair.

Erin and Abby will require additional surgeries as they mature. Their CHOP team, who has been caring for them since birth, will continue to monitor them as they grow up. The team is optimistic about their progress so far and about their long-term potential. Read more in this update from Oct 22.

"The girls are inspiring," said Heather Delaney, mother to Erin and Abby. "As their parents, it is very neat for Riley and me to have a front-row seat to this and watch them overcome these incredible obstacles. We cannot wait to see what their future holds!"

"The team at Children's Hospital of Philadelphia has become like family," added Heather. "Riley and I are so grateful for the care our girls have received here and so excited to take them home —just in time for the holidays."

About Conjoined Twins: 
Doctors at Children's Hospital of Philadelphia have separated 24 sets of conjoined twins since 1957, more than any other hospital in the Western Hemisphere. The physicians have also managed the care of many others whose separation was not surgically possible. Conjoined twins occur once in every 50,000 to 60,000 births; most are stillborn. Approximately 75 percent of conjoined twins are female and joined at least partially in the chest and share organs with one another. If they have separate sets of organs, chances for surgery and survival are greater than if they share the same organs. Craniopagus, represented by fusion of the skull, is the least common type of conjoined twins, accounting for 2 percent of cases.
