Rarely, the brains are separated by bone and each brain has separate leptomeninges. In others, the brains are connected, or separated only by arachnoid, making separation extremely difficult and dependent upon a superior sagittal sinus for each brain. For the duration of the pregnancy, the Center team will work closely with your referring obstetrician to ensure comprehensive prenatal monitoring.
In some cases, care will be transferred to the Center around 28 weeks' gestation or earlier to optimize management of the pregnancy and prepare for delivery. The SDU offers unmatched continuity of care for both mother and baby, with complete labor and delivery services in immediate proximity to the care your babies will need after birth — neonatal intensive care, cardiac intensive care, pediatric operating rooms and more.
After being born connected at the head, Erin and Abby celebrated their first birthdays as two unique little girls. Delivering in a location with direct access to all the advanced, specialized services both mom and baby might need is particularly important for high-risk conjoined twin pregnancies that require a C-section or a potential ex utero intrapartum therapy EXIT delivery. The EXIT procedure is a "partial delivery" in which the fetus is partially removed from the uterus but remains attached to the circulation carried by the umbilical cord and placenta so that surgeons can correct airway blockages before performing a full delivery.
A comprehensive post-delivery assessment will determine the long-term plan for a potential separation surgery. While some life-threatening conditions may require immediate emergency surgery, a full assessment of shared structures should be performed before separation is attempted. Comprehensive evaluation of the cardiovascular system is particularly important in determining if separation is an option.
Specialists involved in your care will likely include neonatologists, cardiologists, advanced practice nurses and maternal-fetal medicine specialists, among others. One of the many procedures required to prepare twins for separation is the insertion of tissue expanders to increase the skin surface available to cover exposed tissue after surgery.
As separated twins recover after surgery, they are closely followed by nutritionists, developmental pediatricians and other specialists to ensure their ability to thrive and grow. Since , pairs of conjoined twins have been referred to the Center for Fetal Diagnosis and Treatment, and 40 pairs have undergone prenatal evaluation. Not all conjoined twins are candidates for separation, and the success rates for separating conjoined twins vary depending on the connection.

The following imaging tests are used to diagnose and evaluate conjoined twins: Fetal ultrasound : a safe, noninvasive procedure that uses high frequency sound waves to provide detailed high-resolution images, including 3-D and 4-D views. Our team of board-certified radiologists uses highly specialized equipment to ensure the best images possible are obtained. Fetal echocardiogram : a noninvasive ultrasound procedure that assesses the structure and function of the fetal heart.
Fetal echocardiogram is the most important test for the evaluation of conjoined twins, as it determines if the twins share a heart and if so, where that connection occurs.
The sisters became an entertainment sensation in both the United States and Europe, sometimes referred to as the Eighth Wonder of the World or as the Two-Headed Nightingale.
They performed in Philadelphia's concert hall at Chestnut and 12th Streets in the midth century see advertisement below. With the wealth from their career, Millie-Christine bought the former McCoy property where they had been born as slaves.
The sisters died in October and their headstone was inscribed: "A soul with two thoughts. Two hearts that beat as one. Arguably the most famous conjoined twins were two brothers, Chang and Eng Bunker, who were born in in Samut Songkram, Thailand in older literature their birthplace is named Mekong or.
Bangaseau in Siam. The brothers were the first to be referred to as Siamese twins. Barnum Circus. Eng and Sarah had ten children, while Chang and Adelaide had twelve. Allison went home in time for Christmas, and Amelia shortly after.
For both girls, that homecoming was their first time outside of the hospital. The girls required some special care, including feeding tubes, during their first few months at home.
But by the end of the summer, the feeding tubes were gone and both girls were up walking and running. The girls are now in preschool. Allison loves animals and wants to be a vet when she grows up. Amelia loves to catch and throw a ball, and is good at kicking a soccer ball. Allison would eat pizza for every meal if she could, even breakfast, while Amelia loves homemade macaroni and cheese and vegetables, especially broccoli and asparagus.
For show-and-tell at their preschool, the girls recently decided to share pictures of when they were connected. They decided together and asked us for pictures.
Shellie and Greg bring the girls back to CHOP for periodic check-ins with their medical team, though the visits are getting less frequent. While they may not need CHOP as much anymore, the family will always treasure what the entire medical team did for them.
