Pediatric neurosurgery

Our neurosurgery specialists at UC Davis Children’s Hospital are committed to setting the standard for the surgical treatment of infants and children with neurologic diseases.

Neurosurgical problems seen by pediatric neurosurgeons are often quite different from those commonly seen by adult or general neurosurgeons. Because pediatric neurosurgical problems often are present for life, children with nervous system problems frequently require close, ongoing follow-up from childhood—sometimes as early as the newborn period—through the teenage years. As a result, pediatric neurosurgeons have special, long-term relationships with their patients and their families.

Conditions we treat

In cooperation with pediatric experts across other specialties, our pediatric neurosurgeons provide advanced clinical care and surgical intervention for children suffering from diseases that affect the developing brain, spinal cord, and peripheral nervous system, including:

  • Brain tumors
  • Cerebrovascular disorders
  • Chiari malformation and syringomyelia
  • Complex spinal disorders and congenital spine anomalies
  • Craniofacial anomalies and craniosynostosis
  • Epilepsy
  • Hydrocephalus
  • Movement Disorders (including dystonia, essential tremor, juvenile Parkinson's disease)
  • Pituitary disorders and tumors
  • Spasticity
  • Spina bifida (including fetal repair)
  • Spinal Cord tumors
  • Traumatic brain and spine injury

    Marike Zwienenberg, M.D., F.A.A.N.S.

    Health Sciences Associate Clinical Professor

    Dr. Zwienenberg, a specialist in pediatric neurological surgery, is fellowship-trained and board certified by the American Board of Pediatric Neurosurgery. She is an expert in treating brain tumors, hydrocephalus, craniofacial disorders, epilepsy, traumatic brain injury, and spinal dysraphism (spinal cord abnormalities caused by malformation of the spinal column during fetal development). She is part of the fetal surgery team performing intra-uterine repair of myelomeningocele and routinely uses minimally invasive surgery (endoscopy) to treat disorders such as craniosynostosis and hydrocephalus.

  • Yin Allison Liu, M.D., Ph.D.

    Assistant Professor, Department of Ophthalmology & Vision Science | Assistant Professor, Department of Neurology

    Dr. Liu is a neuro-ophthalmologist offering care to children with neurological conditions that affect vision. Her research focuses on using the eye as a window to the brain. By applying novel ophthalmic imaging technologies, Dr. Liu strives to establish biomarkers for disease activity monitoring and visual outcome prediction in several neuro-ophthalmic conditions, such as giant cell arteritis, brain tumors, and skull base conditions.

An important distinctionA level I Children’s Surgery Center
ACS badge

UC Davis Children’s Hospital was the first hospital on the West Coast, and only the fourth in the nation, to earn verification as a level I Children’s Surgery Center by the American College of Surgeons (ACS), the world standard bearer for surgical quality.

Level I centers have children’s surgeons in every discipline, with pediatric anesthesiologists and dedicated operating rooms for children available 24 hours a day.
