A safe and effective treatment for vascular lesions

Cutaneous vascular disorders have already been treated with a number of medical methods, from sclerotherapy to energy-centered devices like lasers and extreme pulsed light (IPL), and even surgery. Based on the prolonged theory of selective photothermolysis, long-pulsed lasers are favored, with numerous wavelengths having been utilized to take care of vascular lesions  successfully and safely, including 577 nm, 585 nm, 595 nm, 532 nm, 755 nm, 1064 nm and others. 


Due to its feature of a higher absorption coefficient in hemoglobin, pulsed dye laser (PDL) is among the mostly used devices to treat vascular lesions, such as for example telangiectasia, rosacea etc. However, PDL has a train pulse connected with microseconds, which can result in blood to leak from the vessel wall structure and bring about purpura. Also, because the medium can be a  consumable dye, high maintenance costs are needed. 


Studies show that KTP offers a similar effect to PDL, but with the added good thing about improved ease and comfort and reduced purpura, rendering it a  suitable option wavelength. With an increased absorption coefficient in hemoglobin, it delivers a easy pulse profile, rather than spiky profile period, which results in a decrease in the incidence of purpura when dealing with vascular lesions. 


I take advantage of the long-pulsed KTP and Nd:YAG laser beam, V-laser, produced by Wontech  <> , Ltd., Co. (Daejeon, Southern Korea), and am extremely satisfied with its performance and scientific outcomes. 


V-laser includes a square-shaped pulse and is named a genuine long pulse. The pulse duration could be adjusted over a variety, allowing physicians to change the pulse width predicated on the size  of the lesion. For smaller sized vascular lesions sized significantly less than 1 mm, 10-12 ms are usually used, and for bigger vascular lesions from 2-4 mm, 20-40 ms are used. 


The V-laser system has a dual wave-size of 532 nm and 1064 nm. I take advantage of the 532 nm KTP to take care of reddish and superficial lesions, such as telangiectasia, cherry angioma, rosacea, hemangioma and diffuse inflammation, as the 1064 nm Nd:YAG is used for the treating blue and deep veins like venulectasia, reticular veins and others. 


For leg veins bigger than 2-3 mm, surgery is generally required. However, I've achieved very satisfactory clinical outcomes using the V-laser. Patients are also content with the V-laser beam  treatment because of improved comfort and minimal post-treatment problems compared to surgery.


A 3 mm spot size is often used for vascular lesions, but occasionally a 5 mm spot size can be used. However, it is necessary to keep in mind that for effective and safe procedures with larger place sizes,  you need to fine-tune the parameters and cooling temps. 


The V-laser has a contact coolant system that is extremely efficient in increasing procedural comfort and skin cooling without consumables. And the sapphire windows is huge enough to provide an ideal view of the treatment area. Cooling temperatures can be modified in five actions (off, 5° C, 10° C, 15° C, 20° C) in order that treatment can be carried out at the  appropriate temperature for every lesion. 


Clear gel is used when treating vascular lesions because coloured gels can respond to the laser energy. The gel enhances cooling ability, which increases comfort and ease and aids in preventing thermal damage.


With a long-pulsed KTP and Nd:YAG, benign pigmented lesions may also be treated (i.electronic. lentigines, dyschromia, freckles, pigment, post-inflammatory hyperpigmentation, poikiloderma, etc.). While benign pigmented lesions are generally treated with Q-switched lasers, by providing a photothermal effect rather than a photomechanical impact, a long-pulsed laser delivers a gentler treatment when it comes to adverse unwanted effects and downtime. 


Even melasma could be treated with KTP and Nd:YAG. KTP functions as a pigment remover and Nd:YAG can be used to decrease the feeding vessels and/or enhance the dermal environment. 


The dual wavelength could also be used in additional indications, including inflammatory lesions and skin rejuvenation. V-laser effectively treats inflammatory lesions such as for example acne vulgaris,  offering photo-dynamic results on P. acnes and sebaceous glands.


For pores and skin rejuvenation, the 532 nm KTP eliminates pigmentation and diffuse redness, and improves boring complexion. The 1064 nm delivers bulk heating system to the dermis, therefore stimulating fibroblasts for neocollagenesis. Furthermore, the mix of V-laser beam treatment with hyaluronic acid and/or neurotoxin can offer dramatic epidermis rejuvenation and skin revitalization outcomes. 



The V-laser includes a selection of spot sizes by means of cartridges so that you can select a spot size that's appropriate for the procedure area and/or lesion. Another benefit is that actually if  one cartridge is certainly broken, you don’t have to replace all the cartridges. 


One more thing to emphasize with the V-laser system is that it is made to delay the 1st laser irradiation about 0.5 seconds. This decreases KTP harm, thus decreasing the necessity for maintenance and raising the duration of the device. 


Most patients who arrive to my clinic desire solutions for vascular and/or pigmented lesions and pores and skin rejuvenation. The V-laser’s versatility and simplicity let me treat most of these  indications and more, securely and effectively.
