Laser Vein Treatment
Lasers treat vascular anomalies by emitting a wavelength that is preferentially absorbed by hemoglobin (the red portion of blood) in the targeted vessels. The laser causes the vein to collapse and eventually be absorbed by the body. Advantages include the speed and noninvasive nature of treatment, as well as the size and depth of vessels that can be treated. The exact cause of these smaller, more superficial veins is not yet known; however, heredity is a speculated component. Other possible factors may include hormonal changes associated with puberty, pregnancy, and menopause; constrictive clothing; use of birth control pills; and excessive sun exposure.
Sclerotherapy is a medical procedure used to eliminate varicose and spider veins. It involves injecting a solution (generally a saline) directly into the vein. The solution irritates the lining of the blood vessel causing it to swell, stick together and the blood to clot. Over time the vessel turns into scar tissue and fades from view.
