We are aware of a recent Buffalo News article about another local organization with a similar name to UBNS (UB Neurosurgery). Due to the influx of inquiries and potential confusion we wanted to let our patients, referring providers, hospital partners and the Western New York community know that the article is not related to UBNS (UB Neurosurgery). UBNS (UB Neurosurgery) is not the organization being discussed in the article. UBNS (UB Neurosurgery) operations remain separate and independent from the organization being mentioned.

Contact Dr. Levy and his team for a trusted second opinion on your AVM or aneurysm diagnosis.

Cerebrovascular Disease

Cerebrovascular disease includes all disorders in which an area of the brain is temporarily or permanently affected by a blockage of blood flow to the brain (ischemia) or bleeding into the brain (hemorrhage) by one or more of the cerebral blood vessels in the brain. Cerebrovascular disease includes stroke, carotid stenosis (narrowing of the carotid artery), vertebral stenosis (narrowing of the vertebral artery) and intracranial stenosis, aneurysms, and vascular malformations. Strokes occur when blood flow is restricted due to vessel narrowing (stenosis), clot formation (thrombosis), blockage (embolism) or blood vessel rupture (hemorrhage) or lack of sufficient blood flow (ischemia) affecting brain tissue.

Minimally invasive endovascular neurosurgery refers to treating vascular diseases in the brain using microcatheters that are inserted into an artery and passed up into the brain where tiny devices can be placed to open blocked vessels or divert blood flow away from an aneurysm.

Neurosurgical Conditions Treated:

  • Endovascular
  • Stroke
  • TIA
  • AVM
  • AVF
