Vascular Malformations

Also known as: Vascular Malformations, VM’s.

What are vascular malformations?

A vascular malformation is frequently a congenital abnormality (can sometimes develop after birth) where clusters of blood vessels develop (grow abnormally or connect in an unusual way) during fetal development (while the baby is in the uterus).There are a number of subtypes which include “port wine stains” (capillaries), venous malformations, lymphatic malformations, arteriovenous malformations and mixed vessel abnormalities. Boys and girls are equally affected. Depending on the type , position and size of the VM, clinical presentations will vary. In the brain, they often present incidentally or with headaches, seizures and stroke like manifestations. VM’s may be sporadic or be the result of an inherited gene abnormality.

How are Vascular Malformations Diagnosed?

Ultrasound, magnetic resonance imaging (MRI) and computed tomography (CT scans) play an important role in diagnosis and evaluation of vascular malformations.

How are Vascular Malformations Treated?

Depending on the the malformation and clinical presentation treatments may be medical, surgical and/or interventional radiological (for example sclerotherapy).

We provide the most up-to-date methods in treatment of childhood vascular malformations. Our team of pediatric doctors, technicians, nurses and child life specialists are experts in addressing the special needs of children, focusing on pain control and alleviating anxiety. Our procedures are performed with sedation to assure patient comfort.

Every vascular malformation is unique; therefore, an initial consultation and examination with an interventional radiologist is performed prior to treatment.

What to Expect on the Day of a Sclerotherapy Procedure:

  • An ultrasound will be performed prior to the procedure. 
  • The procedure will take approximately 1 hour, but can be longer for complicated cases. 
  • Most children are able to go home the same day, but some may be kept in the hospital overnight for observation. 
  • Usually there is only minimal post procedure pain, controlled with Tylenol® if needed.
