Our approach and results have garnered recognition from top centers throughout the United States and internationally. Complex cases are referred to us on a regular basis for consideration, particularly those that have failed treatment or been turned down for treatment elsewhere.


Intense subspecialization

At the National Brain Aneurysm & Tumor Center, our neurosurgeons are highly subspecialized and dedicated to treating and caring for patients with complex problems involving:

  • neurovascular issues—the blood vessels bringing blood supply to the brain

  • skull base surgery—complicated brain tumors including those that involve the base of the skull.

On a daily basis, our neurosurgeons care for patients with brain aneurysms, vascular malformations, carotid artery narrowing, and brain tumors including meningioma, acoustic neuroma, glioma and other complicated tumors. We perform a high volume of complex surgeries including brain bypass surgery.

We specialize in open microsurgery as well as CyberKnife stereotactic radiosurgery, and we partner with a highly experienced endovascular group to offer patients the full spectrum of options including coils and stents for aneurysms and embolization for vascular malformations.

Instead of trying to do everything in the specialty of neurosurgery, we focus exclusively on these complex problems. We treat a high volume of cases and, as a result, we offer outcomes that rival the best centers in the world.

Our approach and results have garnered recognition from top centers throughout the United States and internationally. Complex cases are referred to us on a regular basis for consideration, particularly those that have failed treatment or been turned down for treatment elsewhere. 

This intense subspecialization in neurovascular surgery, skull base surgery and stereotactic radiosurgery has allowed us to develop great expertise in the management of even the most complicated problems. We are the busiest neurovascular and skull base practice in the Upper Midwest by patient volume.

Individualized care

The National Brain Aneurysm & Tumor Center neurosurgeons and advanced care practitioners are on the Medical Staff at United Hospital in St. Paul, Minnesota. Its Neurovascular program is one of the busiest by volume in the country and is a five-state regional referral quaternary center for patients traveling from around the world for our services.

We offer a multi-disciplinary team including neurovascular surgery, interventional neuroradiology, stroke neurology, neurocritical care and CyberKnife neuro-radiosusrgery. As a result, we are able to offer patients all options of care and a balanced, thoughtful approach for the treatment of brain aneurysms, brain tumors, vascular malformations, stroke and occlusive cerebrovascular disease.

Our practitioners have treated more than 5,000 brain aneurysms ranging from small, simple lesions to the most complex, giant and fusiform aneurysms that have been turned down repeatedly by other centers and considered “untreatable.” We are the only center in the Upper Midwest and one of the busiest in the country performing brain bypass on a regular basis.

Under the leadership of Eric Nussbaum, MD, our team has experience with more than 500 brain bypass procedures in which tiny blood vessels are connected surgically to reroute blood flow around blocked or diseased arteries deep within the brain.

Our surgeons also have an active clinical and translational research program, which leverages our extensive experience to advance the field and improve care and outcomes. In this capacity, our team is actively involved in publishing scientific papers, writing neurosurgical textbooks, presenting findings at national conferences, participating in clinical trials, as well as developing new devices and bringing them to the bedside for use in patient care.
