Vascular Malformations
Vascular malformations are an abnormally formed combination of capillaries, veins, arteries, or lymphatic vessels. They can appear anywhere on the body and, depending on the type, can cause pain, frequent and uncontrolled bleeding, deformities, or an increased risk of blood clots.
Vascular malformations in the:
- Brain may trigger headaches or seizures.
- Airway can cause speech problems or breathing concerns.
- Eyes can cause vision problems.
- Intestines can cause gastrointestinal bleeding.
Capillary Malformation or Port-Wine Stain
Capillary malformation or port-wine stain is a red or purple flat area on the skin. They are present at birth but can become darker and thicker as a person ages. In rare cases, port-wine stains can be a sign of a serious neurological disorder. Repeated treatments with a laser may lighten large, dark port-wine stains.
Venous Malformation
Venous malformation is a collection of veins that can occur anywhere on the body. Sometimes these areas can become swollen or painful or even bleed. Monitoring is important. Treatment can include compression garments, anticoagulation medication, sclerotherapy (a non-surgical treatment that involves injecting a chemical under ultrasound and X-ray guidance), or surgery. Venous malformations may not cause symptoms until adolescence because growth can be triggered by hormonal changes associated with puberty. Venous malformations are often lifelong issues that require comprehensive team care.
Arteriovenous Malformations
Arteriovenous malformations are abnormal connections between arteries and veins. They require monitoring and early treatment, as they usually grow throughout a person’s life.
Lymphatic Malformations
Lymphatic malformations occur when lymphatic vessels form abnormally during fetal development. They often appear as either small and clear blisters on the skin that do not go away, or as very large swellings, especially of the neck. They typically form in the head or neck area. If the lesion is in the neck, it can be life-threatening. Lymphatic malformations that put you or your child at risk for permanent disfigurement or affect physical, emotional, and social well-being may be treated with drug therapy, laser treatment, or sclerotherapy to shrink the malformation. Surgery may also be recommended to remove the malformation.
