Aim Lasers and non-coherent intense pulse light sources (IPLS) are based on the principle of selective photothermolysis and can be used for the treatment of many vascular skin lesions. A variety of lasers has been developed for the treatment of congenital and acquired vascular lesions which incorporate these concepts into their design. Although laser and light sources are very popular due to their non-invasive nature, caution should be considered by practitioners and patients to avoid permanent side-effects. The aim of these guidelines is to give evidence-based recommendations for the use of lasers and IPLS in the treatment of vascular lesions. Results Lasers and IPLS are very useful and sometimes the only available method to treat various vascular lesions. It is of a paramount importance that the type of laser or IPLS and their specific parameters are adapted to the indication but also that the treating physician is familiar with the device to be used. The crucial issue in treating vascular lesions is to recognize the immediate end-point after laser treatment. This is the single most important factor to ensure both the efficacy of the treatment and avoidance of serious side-effects. Methods Conflicts of interestNone declared. Funding sourceNone.Since the publication of previous European Society of Laser Dermatology (ESLD) guidelines in 2007, there have been significant advances in the field of laser treatment of common vascular lesions.1 These guidelines have been updated by the Consensus Panel under the auspices of the ESLD. Methodology, search strategy and recommendation formulation are described in Appendix II. A brief overview of vascular lasersStandard vascular lasers include pulsed dye lasers (585 and 595 nm), and KTP-lasers (532 nm), followed by longer wavelength lasers such as alexandrite lasers (755 nm), diode lasers (800-900 nm) and millisecond Nd:YAG lasers (1064 nm). New developments include a non-uniform pulse sequence or a dual-wavelength modality (combined dual wavelength 595 and 1064 nm-pulsed dye and Nd:YAG laser) and microsecond Nd: YAG lasers. [2][3][4][5][6] Even fractional photothermolysis has begun to be used for selected vascular lesions. Lasers' and intense pulse light sources (IPLS) effects are based on the principle of selective photothermolysis. In general, they deliver a precisely graded aliquot of energy to a defined area of the skin in a reproducible, standardized manner that almost always involves addition or evacuation of heat.

The Nd:YAG laser, with its 1,064-nm wavelength, is a mainstay for treatment of vascular lesions. What it may sacrifice in absorption by hemoglobin, it makes up for in depth of penetration. The long-pulsed Nd:YAG laser has been the ideal choice for lesions off the face and for thick or deep vascular targets, although newer short-pulsed high-energy (650-μs) devices are showing high efficacy and safety on facial vessels as well. Common uses include leg veins, port-wine stains, blue vessels, and venous lakes. Care must be taken to use adequate cooling during treatment. The Nd:YAG laser is a versatile wavelength with many possible uses for both pigmented and vascular indications. © 2014 S. Karger AG, Basel Vascular lesions, such as port-wine stains and hemangioma of infancy, have been the first and most evident uses for cutaneous lasers in dermatology. However, there are many other uses for these lasers, some vascular in nature and some using the same target, but for a different purpose. The shorter wavelength vascular lasers, including the pulsed dye laser, were the initial lasers implemented for these indications. Over the past 20 years, advancements including using other wavelengths, such as 532 nm [KTP (potassium-titanyl-phosphate)], 755 nm (alexandrite), and 1,064 nm [Nd:YAG (neodymium:yttrium-aluminum-garnet)] have expanded available treatments for these and other vascular conditions. The Nd:YAG laser has become a vital wavelength in treating many cutaneous conditions, including hemangiomas of infancy, port-wine stains, leg veins, venous lakes, telangiectasias scars and photorejuvenation.The first reports of the Nd:YAG laser being used for vascular lesions was in the early 1980s [1,2]. Parkin and Dixon [1] used an Nd:YAG laser to successfully photocoagulate intranasal telangiectasias in patients with Osler-Weber-Rendu syndrome. In 1986, the Nd:YAG was used on hypertrophic port-wine stains [3]. The fluence used was very high with no epidermal cooling, resulting in coagulation at a great depth, but with posttreatment necrosis of the epidermis and scarring [4]. Histologic investiga-

“…Because the absorption coefficient of hemoglobin is low at 1,064‐nm and because water is a competing chromophore, high fluences must be used to obtain vascular destruction, which increases the potential for collateral damage to the skin . The traditional millisecond Nd:YAG laser has been shown to be associated with a significantly higher risk of scarring than the KTP laser for the treatment of vascular lesions such as cherry angiomas . A 1,064‐nm Nd:YAG laser with a microsecond pulse duration may be able to treat small vessels with less pain and with a better risk profile than the traditional millisecond‐pulse‐duration Nd:YAG.…”

Comparison of the 532-nm KTP and 1064-nm Nd:YAG lasers for the treatment of cherry angiomas

Abstract: Both KTP and Nd:YAG lasers were found to be effective methods. The Nd:YAG laser offered fewer treatment sessions, but a higher risk of scar formation. The KTP laser seems more advantageous, but in dark-skinned patients the Nd:YAG laser may be preferable.
