Central nervous system vascular malformations are abnormalities of blood vessels in your brain or spinal cord and their membranes.

Central nervous system vascular malformations are rare and include:

  • Arteriovenous malformations. A brain (intracranial) arteriovenous malformation is an abnormal tangle of blood vessels in your brain.
  • Capillary telangiectasias. Capillary telangiectasias are small dilated blood vessels (capillaries).
  • Cavernous malformations. Cavernous malformations are abnormally formed blood vessels in your brain or spinal cord that have the appearance of a mulberry.
  • Dural arteriovenous fistulas. Dural arteriovenous fistulas are abnormal connections between arteries and the tough covering over the brain or spinal cord (dura) and a draining vein.
  • Spinal arteriovenous malformations. A spinal arteriovenous malformation is an abnormal tangle of blood vessels on, in or near your spinal cord.
  • Venous malformations. Venous malformations are abnormally enlarged veins in your brain or spinal cord.
  • Teamwork. Mayo Clinic doctors trained in nervous system conditions (neurologists), brain, spine and peripheral nerve surgery (neurosurgeons), hereditary conditions (medical geneticists), radiology, radiation oncology and other specialties work together as a team to care for people who have central nervous system vascular malformations and other neurological conditions. Doctors trained in pediatric neurology treat children at Mayo Clinic in Minnesota.
  • Ongoing research. Doctors remain at the forefront of research to refine and improve diagnostic testing and treatment options for central nervous system vascular malformations.
  • Technology. Mayo Clinic doctors use an extensive amount of technology, including advanced imaging tests, to diagnose your condition.
  • Treatment expertise. Mayo Clinic offers a variety of treatment options, including stereotactic radiosurgery and endovascular procedures. Your doctor will work with you to create an individualized treatment plan to help you manage your condition.
  • Efficiency. In Mayo Clinic's efficient system, your testing and treatment can be done in days, not weeks.
