The highly accomplished neurosurgeons at the St. Mary Neurosciences Center are dedicated to caring for people who need specialized surgical interventions for some of the most challenging conditions that affect the brain, spine, and nervous system. Every day, St. Mary neurosciences experts solve the most complex cases using advanced procedures and treatment technologies never before imagined. Whenever clinically appropriate, our team uses a minimally invasive approach, enabling us to treat even the most difficult cases with greater levels of surgical skill and precision.

Areas of Expertise

  • Acoustic neuromas
  • Aneurysms
  • Arteriovenous malformations
  • Cerebrovascular diseases
  • Cervical neck surgery
  • Chiari malformations
  • Chronic back pain
  • Colloid cysts
  • Degenerative disc disease
  • Epilepsy
  • Intracranial hemorrhages
  • Meningiomas
  • Metastatic brain tumors
  • Movement disorders
  • Peripheral nerve disorders
  • Spine surgery

Neurosurgical Capabilities

  • “Brain Lab” computerized brain mapping, which allows our specialists to biopsy and treat brain tumors with unprecedented precision
  • Complex and minimally invasive spinal surgery, including kyphoplasty for the treatment of spinal compression fractures due to osteoporosis
  • Frameless Stereotactic Radiosurgery (SRS), a non-invasive cancer treatment that requires no anesthesia
  • High definition microscopes for brain and spine surgery

Neurovascular Surgery and Endovascular Neurosurgery

Two of the fastest growing subspecialties within the St. Mary Neurosciences Center are in the areas of neurovascular surgery and endovascular neurosurgery. Our highly skilled surgeons specialize in the evaluation, diagnosis, and treatment of aneurysms, arteriovenous malformations (AVMs), intracranial hemorrhages, stenosis, stroke, transient ischemic attacks (TIAs), and other vascular disorders that affect the brain and spinal cord. In appropriate patients, many of the procedures are performed with minimally invasive techniques.

Neurovascular and Endovascular Capabilities

  • Aneurysm coiling
  • Carotid stenting
  • Clot retrieval
  • Endovascular neurosurgery
  • Epilepsy surgery
  • Minimally invasive coronary and cerebral angiography procedures
  • Tumor embolization to reduce bleeding during surgery
  • Vascular malformation management

Interventional Neurosurgery

The neuro-interventional surgeons at St. Mary Medical Center are medical doctors with specialized training and board certification in their field of expertise. These highly skilled physicians use image guidance to perform a variety of advanced, minimally invasive techniques for the diagnosis and treatment of central nervous system vascular diseases. Some of the technologies used by our interventional team include three-dimensional digital imaging, ultrasound, CT scans, digital X-rays, and MRI.

For many patients, neuro-interventional procedures are an excellent treatment option for neurological conditions that once required highly invasive surgical interventions. Conditions that now can be treated non-invasively include:

  • Aneurysms
  • AVMs
  • Tumors of the brain and spine

Further, our neuro-interventional surgeons can provide treatment in emergency situations, when minutes — or even seconds — are critical to successful outcomes. Our neuro-interventionists are available 24/7.


“The amazing detail provided by this high-tech imaging system enhances our capabilities to perform the most delicate procedures in the most vulnerable regions of the body. This will greatly benefit the existing and future healthcare needs of our community.”
