In treating spider veins, many patients have found success through laser vein therapy. This treatment has been used as an option to, or perhaps in conjunction with, sclerotherapy. Those being affected by spider veins are encouraged to explore their treatments using a qualified physician inside their area. Sclerotherapy is often considered the gold standard for spider veins, but laser and pulsed light therapies would be the preferred method occasionally.
The differences relating to the VNUS closure procedure and EVLT are subtle. Both are endovenous anyway; meaning, spider veins are accessed and treated in the veins. Whereas, the former utilizes a disposable catheter furnished with a radiofrequency (RF) generating electrode, aforementioned works on the reusable laser producing fiber. RF closure was introduced in Europe in 1998 and was cleared with the US Food and Drug Administration (FDA) in March 1999. Endovenous laser vein treatment was described in 1999 and FDA approved that year 2002. It should be noted that EVLT is a trademarked term and lots of other acronyms, for example EVLA and CTEV, are trademarked with claims that their laser fibers and wavelength lead to less pain than these. Although many different radiofrequency ablation catheters are available for various medical applications, the ClosureFAST catheter and ClosureRFS Stylet, manufactured by VNUS Medical Technologies, currently will be the only commercially ready and FDA approved systems suitable for venous ablation.
They are seen as an weakened veins which can be near to the surface of the skin. They tend to get stretched which is the causes of them to be weaker than a normal vein. This occurs when blood pools inside a vein as a result of damaged or malfunctioning valves from the veins themselves. When the blood pools, the vein is forced to grow, stretching and weakening the walls from the vein.
To treat spider veins, sclerotherapy is a reasonably common method employed by individuals suffering from this vein problem and vein specialists providing treatment. Sclerotherapy involves injections of your chemical sclerant in the problem veins. This irritates the vein wall, creating the vein to collapse, shrink and disappear. The needles used to increase the risk for injections are very small that most do not require a topical anesthetic, although some people might may prefer this for comfort. There is no recovery period related to sclerotherapy, as most folks are in a position to resume normal activities or resume work immediately after treatment.
Our skin cells have liver spots called melanin. In laser treatment, laser of various wavelength and high concentration is passed over the skin. As the dark object sucks light, the melanin catches the sunshine. The particular cell gets warmed and destroyed without hurting one other cells of the epidermis. As there are only two kinds of melanin inside hair, this beam can destroy only black or brown hair. Source= natural remedies for varicose veins
