Dr. John C. Barr

My clinical mission is to advance the science and practice of cerebrovascular neurosurgery to new uncharted frontiers. I aim to provide patients seeking neurosurgical treatment at Duke Health with world-class clinical care and surgical management. I partner with patients and their families to achieve excellent clinical and surgical outcomes. I treat patients as I would treat my own family members: with passion, compassion, and respect. I do my best to give patients hope that they might find at other places. I lead a team of scientists and clinicians that strive to make innovative advances in treatment devices, alternative therapeutic agents for cerebrovascular diseases, and surgical approaches. If you or your loved one have a cerebrovascular disease, such as a brain aneurysm, AVM, dural AVF, stroke, intracranial atherosclerotic stenosis, carotid diseases, moyamoya, or vascular tumors, and want world-class care, Duke Health must be your choice.

I specialize in skull base tumors, certain vascular tumors that affect the brain, brain aneurysms, and strokes. Skull base tumors usually occur in a hard-to-reach area where there are a lot of sensitive structures. I have devoted many hours to perfecting my technical skills and my surgical approaches. Skull base tumors tend not to be malignant, so if you can remove the tumor cleanly, you can cure the patient. It's thrilling to be able to reassure the patient and family that they don't have to worry about this disease anymore. Having these conditions can be a scary time in patients’ lives, and I have committed myself to helping them through the process. It's also important to be able to perform surgery in a setting where the patient has the best likelihood of a good outcome. That's what makes Duke stand out: We do rare things frequently and, as a result, we're quite good at them.
