KTP Laser and Facial Telangiectasias

Can’t say that I find this abstract encouraging, but it at least shows that there is some interest in this laser and facial vessels.

Treatment of superficial cutaneous vascular lesions: experience with the KTP 532 nm laser., Lasers in Medical Science, August 2004, 19(1):1-5. Clark C, Cameron H, Moseley H, Ferguson J, Ibbotson SH.

Abstract: Whilst most facial telangiectasias respond well to short-pulse-duration pulsed dye laser therapy, studies have shown that for the treatment of larger vessels these short-duration pulses are sub-optimal.

Long-pulse frequency-doubled neodymium:YAG lasers have been introduced with pulse durations ranging from 1-50 ms and treatment beam diameters of up to 4 mm.

We report the results of KTP/532 nm laser treatment for superficial vascular skin lesions. The aim was to determine the efficacy of the KTP/532 nm laser in the treatment of superficial cutaneous vascular lesions at a regional dermatology centre in a 2 year retrospective analysis. Patients were referred from general dermatology clinics to a purpose-built laser facility. A test dose was performed at the initial consultation and thereafter patients were reviewed and treated at 6 week intervals.

Outcome was graded into five classifications by the patient and operator independently based on photographic records: clear, marked improvement, partial response, poor response, and no change or worsening.

Over the 2 year period, 204 patients with 246 diagnoses were treated [156 female; median age 41 (range 1-74) years; Fitzpatrick skin types I-III]. Equal numbers of spider angioma (102) and facial telangiectasia (102) were treated. Of those patients who completed treatment and follow up, 57/58 (98%) of spider angiomas and 44/49 (90%) of facial telangiectasia markedly improved or cleared.

Satisfactory treatment outcomes, with one clearance and two partial responses, occurred in three of five patients with port-wine stain. Few patients experienced adverse effects: two declined further treatment due to pain, and a small area of minimal superficial scarring developed in one case. Two patients developed mild persistent post-inflammatory hyperpigmentation, and one subject experienced an episode of acute facial erythema, swelling and blistering after one treatment.

The KTP/532 nm frequency-doubled neodymium:YAG laser is a safe and effective treatment for common superficial cutaneous vascular lesions in patients with Fitzpatrick skin types I-III

    Hi, ive had treatment for redveins/spider viens in my face and the treatment i have had was ipl and vienwave, ipl kinda helped with the redness ie by toning it down but didnt really do anything for the spider veins themselves, now the the veinwave in the beginning was very good, my face was left very red after the treatment for a good two weeks but the spideveins came back!!! now will ktp/yag laser help by permanatly removing the veins or will i have to go for something a bit stronger like pdl laser?? please help.
