Dr. Antezana has been a neurosurgical consultant in Portland since 2002. He earned a Bachelor of Science in biomedical engineering from Catholic University of America, and an M.D. from the University of Minnesota. He later completed residency and fellowships at Johns Hopkins Hospital in neurological surgery, cerebrovascular research and orthopedic spine surgery. Dr. Antezana is Providence Health & Services’ lead investigator on two NIH-sponsored trials; and his research on neurophysiological monitoring in surgery has been presented at major international neurosurgical conferences. He currently serves as the chair of neurosurgery at Providence Portland Medical Center.

When Dr. Antezana is not working he enjoys hiking and skiing.

Research

• Spinal deformity surgery outcomes and complications
• Neurophysiological monitoring in surgery
• CLEAR-III Clinical Trial: determining whether rapid removal of intraventricular hemorrhage with a recombinant tissue plasminogen activator improves neurologic outcome
• MISTIE-III Trial: determining whether minimally-invasive brain surgery plus recombinant tissue plasminogen activator in patients with intracranial hemorrhage results in improved functional outcome
