Prevea Health

Prevea neurosurgery


Neurological problems can be a passing annoyance or a chronic, debilitating problem. Neurosurgery is the medical specialty that diagnoses and surgically treats patients with diseases and disorders of the brain, spine and peripheral nerves. When surgery is the best option, trust our team to get you back to your healthy, vibrant life.
Our neurosurgeons have a genuine concern for your well-being. They are dedicated to offering high level of care and achieving maximum results, all right here in Northeast Wisconsin. In fact, Prevea has the only neurosurgeon in Wisconsin with an extended fellowship in endoscopic skull base surgery.

first in Wisconsin to use robotic- and navigation-assisted technology for back and neck surgeries

Leaders in brain and spine surgery

Prevea is the first in Wisconsin to use robotic- and navigation-assisted technology for back and neck surgeries and to use Gleolan™, a new, breakthrough tool designed to make the surgical removal of high-grade gliomas more effective.
Partners with Medical College of Wisconsin

Strong partnerships

Prevea Health and Medical College of Wisconsin partner to provide the Greater Green Bay community with the most extensive neurosurgical care available.
board-certified neurosurgeons

Coordinated care

Our neurosurgeons work with a team of skilled physiatrists, spine-trained nurse practitioners, physician assistants, and physical and occupational therapists. Together, they form the team that will guide you through the treatment and therapy process.

Gleolan for high-grade glioma
If a patient requires surgery to remove a high-grade glioma (tumor that arises from the supportive tissue of the brain), Prevea now offers the latest technology to help.
High-grade gliomas, such as glioblastomas, infiltrate into a person’s brain tissue which can make it difficult for surgeons to differentiate between cancerous and non-cancerous tissue in the brain during surgery. In some cases, the cancer appears to disguise itself as healthy brain tissue.
Gleolan is an imaging agent that assists the surgeon in pinpointing where the cancerous tissue is located within the brain. Patients ingest the Gleolan solution 2 to 4 hours prior to the surgery. Then, during surgery, the surgeon views the brain through a special blue light filter on a surgical microscope. Under this blue light, the active substance in Gleolan causes the cancerous tumor cells to appear a red-violet color, while the non-cancerous brain cells appear blue. This differentiation provides the surgeon a better view , allowing them to remove more of the tumor and  less healthy brain tissue. The goal is to remove as much of the tumor as possible without harming areas of the brain that control critical functions such as speech, balance, movement, memory, understanding and vision.
Although high-grade gliomas are generally not curable, the use of this new approach can help extend the length of someone’s life without sacrificing the quality of their life.
