Vascular Malformations of the Brain and Spinal Cord

The neurosurgeons at Houston Methodist diagnose and treat many kinds of brain and spinal vascular malformations.

They are also referred to as cerebral vascular malformations, intracranial vascular malformations and occult intracranial vascular malformations.

Types of Vascular Malformations
Vascular malformations is an umbrella term for several conditions that affect blood vessels to the brain. They are separated into different subtypes with various symptoms, severity and causes:
  • Arteriovenous malformations (AVMs) — abnormal veins and arteries
  • Cavernous malformations — enlarged blood-filled spaces
  • Venous angiomas — a small tangle of abnormal veins
  • Talangiectasias — enlarged capillary-sized blood vessels that arise on the surface of the skin
  • Vein of Galen malformations — the most common type of AVM in infants, it affects the large, deep vein at the base of the brain, also known as the “great cerebral vein,” which is one of the large veins that returns blood from the brain to the heart
  • Mixed malformations — a fairly common congenital (from birth) malformation that usually includes both abnormally developed veins and cavernous malformation
