Venual Malformations (Port Wine Stains) are always present at birth and can range from pale pink to dark purple in color. In the past these lesions were erroneously called “capillary hemangiomas.” Port Wine Stains occur in .3% of births and occur equally among males and females.
The cause has been recently associated with a deficiency or absence in the nerve supply to the blood vessels of the affected area. These nerves control the diameter of the blood vessels. If the nerves are absent or defective, the vessels will continue to dilate and blood will pool or collect in the affected area. The result will be a visible birth mark.
Dr. Hopkins treats birthmarks and hemangiomas with vascular lasers.
