EXIT Procedure Allows Will to Breathe
When Kristin Hileman was 29 weeks pregnant, a routine prenatal checkup found that her gestational measurement was larger than it should have been. An ultrasound showed a mass on her baby’s neck the size of a small orange. Kristin was immediately referred to a specialist who diagnosed the mass as a cervical teratoma.
A cervical teratoma is a tumor that grows on the neck of a baby in utero. It can grow so large that it obstructs the airway of the baby, making it impossible for the child to breathe at birth. This type of tumor is rare, affecting approximately one in 16,000 babies.
Kristin and her husband, Bill, of Columbus, Oh, soon learned that the best chance for their baby’s survival would be for Kristin to undergo what is called an EXIT procedure (ex-utero intrapartum treatment). This procedure combines a surgery on the baby’s airway with a C-section delivery. They were referred to the Cincinnati Children's Fetal Care Center and quickly made arrangements for what turned out to be a lengthy stay.
Help From Afar
The Hilemans were able to take advantage of a concierge service through Concierge Services at Cincinnati Children’s, one of three local hospitals that makes up the Fetal Care Center. This service helps out-of-town families make travel arrangements such as lodging and transportation. That freed up the Hilemans to coordinate care for daughter Brynn, who was 3 at the time.
Upon arriving at the Fetal Care Center on Jan. 17, 2010, Kristin underwent standard prenatal tests including an MRI and ultrasound. She and Bill later met with their care team, consisting of a maternal fetal medicine specialist, fetal surgeon, nurse coordinator, and others who would be involved in the care of Kristin and her baby. They were presented with all of the facts of their case and learned what to expect over the coming weeks until the baby’s delivery.
“We had several team meetings with our doctors,” Kristin says. “It was very helpful. Any time we had an MRI they’d go over all of the results with us.” They not only learned what to expect before their baby’s birth, but also what they would face after delivery and the special needs their baby might have due to complications from the tumor.
“It’s scary to go through something like this,” Kristin says. “There’s a risk for the mom as well as the baby. They really made us feel at home and took great care of us.”
A Complex Procedure
On Feb. 10, at 33 weeks pregnant, Kristin went in for the surgery and delivery. Her procedure, called an EXIT-to-airway, involved putting Kristin under general anesthesia to relax her uterus. Then the surgeons made an incision in Kristin’s abdomen as is done with a standard C-section. Next they lifted out the baby’s head and shoulders while the baby remained attached to Kristin through the umbilical cord. This allows the doctors more time to work on the airway, since the baby is still being supported by the mother.
In Kristin’s case, the doctors needed to create an artificial airway for her baby because the tumor was compressing the natural airway. This involved intubating the baby − inserting a tube into the throat − so that he could breathe once he was fully delivered. The tumor would later be removed after birth during a separate surgery. After they intubated him, the doctors delivered him as during a typical C-section.
A Long Road Ahead
The procedure was a success, and the Hilemans welcomed baby William into their family. The surgery allowed him to breathe through an endotracheal tube. But he had a long way to go. He was so weak, in fact, that Bill’s family drove through a snow storm from Michigan to meet baby Will because they weren’t sure he would make it.
“He was so very sick,” Kristin says of Will, who had immediately been taken to the Newborn Intensive Care Unit (NICU) after his birth. “He needed surgery to remove the tumor from his neck. The operating room was right across from his pod in the NICU, but we didn’t think he could even be moved there because he was so fragile.” Finally, there was a six-hour period of time where Will looked well enough to tolerate the surgery. “It was the longest wait of my life,” says Kristin.
Will proved strong, surviving the surgery and continuing to grow and develop during his stay in the NICU. But his list of challenges was lengthy. Tests showed his tumor was cancerous. His prematurity and prenatal condition combined to present medical challenges including a brain hemorrhage, a diseased thyroid that had to be removed, and a pyloric stenosis, where the contents of his stomach were blocked from emptying into his small intestine.
But Will persevered, and almost three months after he was born, he was finally well enough to be transferred to Nationwide Children’s in the Hilemans’ hometown of Columbus. He stayed there for another month to complete his transition to home care.
