At Dallas Vein Specialists foam ablation or sclerotherapy is routinely used for the treatment of skin spider veins and abnormal larger veins coursing below the skin and above the muscle layer of the leg. When used with ultrasound, foam may be injected into abnormal veins that cannot be seen on the surface but must be treated in order to correct the underlying vein problem. The procedure is virtually painless and easily accomplished in the outpatient office setting.
Liquid chemical solutions that damage the cells lining the inside walls of veins have been used for the injection of unsightly veins for many years. In recent years, some of the chemicals have been made into a fine foam solutions by forceful mixing them with air or carbon dioxide. This foam when injected into veins has been shown to be more effective in causing the vein to succumb to injury and eventually disappear as the body takes it away. With the attachment of the small foam bubbles to the inside wall of the veins more time is allowed for the chemical substance coating the bubbles to cause the injury to the lining cells. This injury is necessary to invoke the body’s mechanism that removes the vein.
