Neurological Surgery Residency

The residency program at UC Irvine's Department of Neurological Surgery is designed to provide experience in adult and pediatric neurosurgical practice. Practice settings include the university's medical center, health maintenance organizations and private practice sites.

Training takes place at UC Irvine Medical Center, San Antonio Regional Hospital in Upland, Tibor Rubin Veterans Affairs Medical Center in Long Beach (VA) and CHOC Children’s Hospital in Orange. These settings offer our residents exposure to a wide variety of patients with neurosurgical conditions.

In addition to these clinical rotations, our residents are trained in neuropathology and neuroradiology. Residents also undergo an extensive didactic program of core lectures, seminars and neurosurgery journal clubs, conferences and grand rounds as well as a full year of research activities that they select.

The residency program, which is fully accredited by the Accreditation Council for Graduate Medical Education (ACGME), was officially launched on July 1, 2008. The seven-year program generally accepts two new resident trainees every other year and one new resident trainee the years in between.

Program Mission Statement

Overview »

The first year (PGY-1) includes five months of surgical training tailored toward neurosurgical relevance; three-months rotation in neuro-critical care; one-month rotation in trauma and a three-months rotation in basic neuroscience. During the the next 6 years, residents receive a variety of required neurosurgical training that includes, for example:

  • PGY-2, 12 months neurosurgery at UC Irvine Health Medical Center
  • PGY-3, 9 months neurosurgery at UC Irvine Health Medical Center; 3 endovascular neurosurgery at UC Irvine Health Medical Center
  • PGY-4, 6 months pediatric neurosurgery at Childrens Hospital of Orange County; 2 months of stereotactic radiosurgery at San Antonio Regional Hospital; 1 month of neuro-oncology; and 3 months clinical neurosurgery at Tibor Rubin Veterans Affairs Medical Center - Long Beach
  • PGY-5, 12 months of research at UC Irvine Medical Center or 12 months of subspecialty electives  (skull base neurosurgery; epilepsy and functional neurosurgery; complex spine; endovascular neurosurgery; neuro-critical care) at UC Irvine Health Medical Center
  • PGY-6, Option 1:  3 months at Tibor Rubin Veterans Affairs Medical Center - Long Beach; an elective consisting of 4 month of interventional radiology, including endovascular surgery, and 2 months of multidisciplinary spine service, both at UC Irvine Medical Center; and 3 months as chief resident at UC Irvine Medical Center
  • PGY-6, Option 2: 3 months at Tibor Rubin Veterans Affairs Medical Center - Long Beach; 2 months of pediatric neurosurgery at Rady Children's Hospital (UCSD);  an elective consisting of 2 months of interventional radiology, including endovascular surgery or 2 months of multidisciplinary spine service; and 3 months as chief resident at UC Irvine Medical Center
  • PGY-7, 9 months as chief resident at UC Irvine Medical Center; 3 months of subspecialty elective

Beginning with the PGY-2-7 year, residents are expected to prepare and submit at least one manuscript annually for peer review publication.

They are expected to take the American Board of Neurological Surgery (ABNS) written examination for either practice or credit each year of training beginning with the PGY-1 year. The earliest year they can take the examination for credit is PGY-4. Residents must pass the ABNS exam by the completion of PGY-6 in order to progress to the final chief residency year.

Assuming these requirements are met and faculty evaluations are satisfactory, a resident will complete the entire program in 7 years.
