The neurosurgeons and neurologists at the Brain Aneurysm Center and the Center for Cerebrovascular Surgery and Endovascular Neurosurgery at Northwell Health Neuroscience Institute provide leading-edge expertise in the diagnosis and treatment of the wide spectrum of neurological conditions, including ruptured and non-ruptured aneurysms, arteriovenous malformations (AVMs) and carotid artery dissection.

Brain aneurysm causes
Brain aneurysms occur in approximately three to six percent of the population. Fortunately, many of these are small and go unrecognized throughout life and do not rupture. Brain aneurysms are thought to arise from a congenital defect in the wall of an artery. However, certain risk factors can contribute to aneurysm formation and the possibility of rupture. Such risks include:

  • Hypertension
  • Smoking
  • Alcohol use
  • Family history
  • Inherited disorders, such as Ehlers-Danlos syndrome, polycystic kidney disease, Marfan syndrome and neurofibromatosis

Brain aneurysm diagnosis
An unruptured aneurysm is typically found incidentally during an unrelated neurological workup or CT or MRI of the brain. Once an aneurysm has been located, a more detailed workup may be required. It is important for your physician to understand the size, shape, location and origin of an aneurysm. This will help to determine how it should be treated. Most of the tests are safe, painless and noninvasive. These include:

  • Computerized tomography (CT)
  • Computed tomography angiography (CTA)
  • Magnetic resonance angiography (MRA)
  • Angiography
  • 3D angiography
  • Transcranial doppler ultrasonography
