This venous laser treatment works by thermal destruction of the vein tissue. The laser energy is delivered to the area of the vein that is incompetent and a variety of wavelengths are used. When the laser is fired, thermal energy is deposited in the blood and venous tissues causing irreversible localized damage. The entire vessel is treated and, although a hole may be made during the laser treatment, permanent changes are caused by the thermal injury. (6,7)
Prior to the procedure your physician will evaluate your health and situation to determine whether or not you are a good candidate. Be sure to report all medications that you are currently taking, including herbal supplements and multivitamins. If you have any allergies, especially to local anesthetic or general anesthetic, you must also advise your physician. Your doctor will talk to you about removing any aspirin, nonsteroidal anti-inflammatory drugs or blood thinners for a specific period of time prior to the procedure in order to decrease the risk of bleeding.
