Vascular Malformations of the Brain

What Are Vascular Malformations of the Brain?

Vascular malformations of the brain is a general term used to classify conditions that affect the blood vessels in the brain. During the fetal development stage, abnormal blood clusters form and can have serious repercussions if left untreated. Vascular malformations may cause seizures, headaches, bleeding in the brain, and strokes.


These conditions include:


  • Cavernomas or cavernous malformations of the brain are vascular abnormalities of the central nervous system. This condition is characterized by a cluster of dilated, abnormal vessels.
  • Cerebral aneurysms explain the ballooning, bulging, or dilation of part of the artery or wall of a vein in the brain.
  • Arteriovenous Malformations (AVM) are tangles of abnormal blood vessels that connect veins and arteries to the brain. These veins are tasked with carrying oxygen-depleted blood back to the heart and lungs. The arteries are responsible for transferring oxygen-infused blood to the brain and heart.

Treatment Options

Vascular malformations will typically grow at a rate proportionate to the child’s development. Treatment options will vary based on the location and severity of the malformation. While advancements in medicine are continually introducing new solutions, the current treatment options include:


  • Resection or surgical removal of the vascular malformation of the brain.
  • Multiple embolization is a procedure where pellets are placed in the circulatory system to constrict blood flow from and to the abnormal blood vessels.
  • Irradiation or radiation treatment use hyper-focused lasers to minimize the vascular malformation.
