Background

Dr. Holly Hedrick is an attending surgeon in the Division of Pediatric General, Thoracic and Fetal Surgery at Children’s Hospital of Philadelphia (CHOP) and the Louise Schnaufer Endowed Chair in Pediatric Surgery. She is also the Surgical Director of the Extracorporeal Membrane Oxygenation (ECMO) Center, Co-director of the Neonatal Surgical Team and Director of the Pulmonary Hypoplasia Program. In addition, she is an investigator in the Center for Fetal Research and a Professor of Surgery at the University of Pennsylvania School of Medicine. 

Dr. Hedrick completed her pediatric surgery fellowship at CHOP and joined the staff as an attending surgeon 1999. “I felt grateful and honored to be trained at CHOP,” she says. “It is a dream come true to work here.” Dr. Hedrick’s areas of interest include neonatal surgery, ECMO, thoracic surgery, and minimally invasive techniques including laparoscopy and thoracoscopy.

Providing Expert CDH Care

This video follows one family’s journey from prenatal diagnosis of CDH through delivery and CDH surgery to discharge home.

Her clinical specialty is treating children with congenital diaphragmatic hernia (CDH), a birth defect in which a hole in the diaphragm allows abdominal organs to migrate into the chest, restricting development of the lungs. Concerned with improving outcomes after surgical repair for these fragile infants, who suffer long-term complications including pulmonary hypoplasia, Dr. Hedrick sought to create a specialized program offering the most complete and current care tailored to the specific needs of patients with compromised lung function. The result was the Hospital’s unique Pulmonary Hypoplasia Program (PHP), founded in 2004, which unites specialists from various disciplines including neonatology, cardiology, pulmonology, audiology and gastroenterology, to provide comprehensive care for CDH patients well into school age. Today, more than 230 patients are followed in the PHP Program.

“It’s been thrilling to work with this truly interdisciplinary team,” she says. “We are very challenged by these diagnoses, but we find it rewarding to see these babies through. It’s not enough to deliver a survivor. We want to give them a high quality of life.”

Dr. Hedrick earned her bachelor’s degree from Indiana University and her medical degree from Duke University School of Medicine. She completed her general surgery residency at Brigham & Women’s Hospital/Harvard Medical School and her residency and fellowship in pediatric surgery at The Children’s Hospital of Philadelphia. Dr. Hedrick also completed research fellowships at Duke University School of Medicine and Harvard Medical School.

In spring 2015, Dr. Hedrick appeared in a three-part documentary series airing on PBS called TWICE BORN: Stories from the Special Delivery Unit. The Emmy® Award-winning documentary offered a look inside the Richard D. Wood Jr. Center for Fetal Diagnosis and Treatment at Children’s Hospital of Philadelphia, and its unique Garbose Family Special Delivery Unit.
