Cerebrovascular Malformations

Dallas Vascular & Neurosurgery Treatments

A cerebrovascular malformation is an abnormal tangle of blood vessels in the brain. These abnormal vessels can alter the blood flow to the brain, causing strokes or seizures. They can also rupture and cause potentially devastating brain hemorrhage.

Types of Cerebrovascular Malformations

Cerebrovascular malformations take many different forms, and they can occur in arteries, veins, and capillaries. Once your doctor has identified the type of cerebrovascular malformation you have, they can start planning the appropriate treatment.

The following are some examples of cerebrovascular malformations

  • Arteriovenous Malformations (AVM) – abnormal tangle of blood vessels in which arteries are connected directly to veins.
  • Dual Arteriovenous Fistula (DAVF) – similar to an AVM, but instead of occurring in the brain itself, DAVF effects the membranes that cover the brain.
  • Cavernous Malformation – benign vascular “clusters” of tiny thin-walled vessels.
  • Venous Malformation – enlarged veins that are usually harmless, but can cause symptoms if they get too big.


Performing surgery on blood vessels in the brain is a delicate process that requires skilled hands. It is highly recommended that you seek treatment from a specialty center like Methodist Moody Brain and Spine Institute that has a multidisciplinary team experienced in treating these conditions.
