Using the theory of selective photothermolysis, benign vascular lesions can be treated with Laser Treatment using the Nd:YAG (1064 nm) and appropriate settings that will cause selective absorption of light in the blood that is flowing through the targeted vessel. The absorption converts light into heat energy, which raises the temperature of the blood. Heat is conducted to the lining of the vessel wall leading to its injury. This results in slow elimination of the vascular lesion by the immune system. All of this should happen selectively and without damage being done to the epidermis or surrounding tissue.
Patient response can vary after a vein removal treatment. Erythema (redness) and edema (swelling) around the treated vessels are usually noted within a few minutes after the completion of the procedure and typically have a “cat scratch” like appearance. A sunburn sensation and a slight feeling of soreness in the area treated are also normal and expected. These reactions tend to subside within 24-48 hours after the treatment.
After 48 hours, the skin over the treated veins will look slightly red, purple, or bruised. Sometimes the veins will be more visible than they were prior to treatment. This is normal. Within the first two to three weeks, the redness and purple color will begin to fade. Each week, the color will become lighter and the veins will become less noticeable. After 2-4 weeks, if any veins are still visible, another laser vein removal treatment will be necessary.
Superficial vascular lesions are most appropriately treated with 1064 nm Nd: YAG ClearScan. Vascular lesions that are bigger than 3 mm, bulging or deeper in tissue should not be treated with cutaneous 1064 nm Nd: YAG ClearScan. Other forms of treatment are more appropriate for these types of vessels.
