Doctor Diagnosis

Venous Malformations develop prior to birth but may not become evident until teen or adult years. They can occur anywhere on the body and are a result of abnormally developed veins while the child is still in the womb. No known outside causes contribute to the formation of a venous malformation. They are the most common type of vascular malformations, seen in one or two out of every 10,000 births.

What Causes a Venous Malformation to Grow?

Many venous malformations do not grow or change over the patient’s lifetime, whether they are detected at birth or later in life. Those that cause no problems are monitored by a doctor and left alone. Your physician may give you some signs to notice that could indicate the growth of your venous malformation, and some situations that might trigger growth or changes. These can include:

  • Increased or sudden stress
  • Increased physical activity
  • Emotional trauma
  • Physical trauma
  • Surgery or removal
  • Puberty
  • Pregnancy
  • Menopause
  • Infections
  • Hormonal changes

When a venous malformation grows, it can cause serious complications, depending on its size, location and how it impacts other aspects of the body. The malformation can bleed or cause pain, or impact nearby structures and cause difficulty with vision, breathing, movement and more. Some venous malformations that impact bones can cause weakening of bone structure that leads to breakage.

How Can Venous Malformation Treatments Help Me?

The specialists at The Vascular Birthmark Institute may recommend certain treatments to alleviate symptoms and preserve function and quality of life. Your treatment recommendations will be tailored to your specific condition and complications. Some of our common treatments for venous malformation complications are described below.

Wearing Compression Sleeves/Garments
Tight-fitting sleeves or garments that fit over the area of the venous malformation compress the growth to restrict it and help with pain, swelling and potential bleeding. This may be combined with other treatment options and is usually the first step when a growing venous malformation is detected.
Laser Therapy
Modern lasers can be targeted to eliminate discolorations from a venous malformation or even close off offending blood vessels to stop bleeding and/or further growth. This treatment is painless and very successful in most cases.
This treatment option uses a chemical to achieve the same results as laser therapy. The chemical is injected into the veins to shrink or close off offending vessels of the venous malformation. It is painless and takes some time to see results.
Surgical Removal
In specific cases, your specialist at The Vascular Birthmark Institute may recommend surgical removal of a vascular malformation. This is particularly true when the malformation impacts bodily functions or structures. Special techniques are used to prevent the formation of a new malformation due to the trauma of surgery.
