  • Treatment of superficial cutaneous vascular lesions: experience with the KTP 532 nm laser
    Lasers in Medical Science, 2004
    Co-Authors: C. Clark, H. Cameron, H. Moseley, J. Ferguson, S. H. Ibbotson
    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.

  • Treatment of superficial vascular lesions with the KTP 532-nm laser: experience with 647 patients
    Lasers in Medical Science, 2014
    Co-Authors: G. L. Becher, H. Cameron, H. Moseley
    Abstract:

    Superficial vascular lesions are a common dermatological diagnosis but are often difficult to treat. Numerous lasers (especially the dye laser) and intense pulsed light sources have been used, but there have been very few reports on the effectiveness of the potassium-titanyl phosphate (KTP) laser. We have extensive experience of this modality at our institution, and the purpose of this survey is to report on the safety and efficacy of the KTP laser. Using an in-house database, we retrospectively collected data from patients who had undergone treatment with the KTP laser for superficial vascular lesions. Patients of Fitzpatrick skin type I–IV were included. Exclusion criteria were Fitzpatrick skin type V, patients with obvious suntan and those on potentially phototoxic medications or minocycline therapy. Diagnoses included discrete or matted telangiectasia, strawberry naevus, Spider Angioma, rosaceal erythema, rosaceal telangiectasia, telangiectatic naevus, Angioma, combined rosaceal erythema/telangiectasia, port-wine stain, venous lake haemAngioma and hereditary haemorrhagic telangiectasia. Patients underwent an initial test treatment and further treatment at 6-week intervals as required. Clinical photographs were taken pre- and post-treatment, and outcome was graded by patient and physician. Adverse effects were recorded including scarring, hypo- or hyperpigmentation, marked swelling, blistering, scabbing and bruising. Six hundred forty-seven patients with 13 diagnoses on 9 different body sites were recorded. Four hundred eighty-six were female, and the median age was 39.5 years. Of the lesions treated, 33.7 % ( n  = 218) were discrete telangiectases and 31.8 % ( n  = 206) were Spider Angiomas. A 92.7 % of lesions were on the face. Four hundred thirteen (77.6 %) patients who had outcomes recorded at 6 weeks were graded as “clearance” or “marked improvement”. Only 38 (5.8 %) patients experienced adverse effects, all of which were minor; the main adverse effect was swelling. Unlike the dye laser, there was only one case of bruising out of 647 patients. This is the largest survey of patients to have undergone KTP laser treatment reported in the literature. Our results show that the KTP laser is a safe and effective modality for the treatment of superficial vascular lesions.

  • Single-center experience with potassium titanyl phosphate (KTP) laser for superficial cutaneous vascular lesions in face
    Journal of cosmetic and laser therapy : official publication of the European Society for Laser Dermatology, 2016
    Co-Authors: Berna Solak, Rabia Oztas Kara, Bahar Sevimli Dikicier, Teoman Erdem
    Abstract:

    Background and objectives: Superficial cutaneous vascular lesions (SCVLs) are quite common. Several types of lasers have been used to treat these lesions; however, there are no dedicated treatment guidelines and few studies in the literature addressed their treatment. Aims: In this paper, we aimed to report our clinical experience with potassium titanyl phosphate (KTP) laser treatment on different types of facial SCVLs including telangiectasia, Spider Angioma, and erythema. Methods: Data were retrospectively collected from 146 patients with SCVLs, who had been treated with the 532-nm wavelength laser at our outpatient dermatology clinic. Treatment responses were graded as four groups: clearance (> 75% improvement compared with the previous session), marked improvement (50–75%), partial improvement (25–50%), and no response (< 25%). Results: The rate of clearance plus marked improvement (favorable outcome) was 66.1% for telangiectasia group, 93.5% for Spider Angioma group, and 26.7% for erythema group. Mea...

    Abstract:

    BACKGROUND AND OBJECTIVES: Superficial cutaneous vascular lesions (SCVLs) are quite common. Several types of lasers have been used to treat these lesions; however, there are no dedicated treatment guidelines and few studies in the literature addressed their treatment. AIMS: In this paper, we aimed to report our clinical experience with potassium titanyl phosphate (KTP) laser treatment on different types of facial SCVLs including telangiectasia, Spider Angioma, and erythema. METHODS: Data were retrospectively collected from 146 patients with SCVLs, who had been treated with the 532-nm wavelength laser at our outpatient dermatology clinic. Treatment responses were graded as four groups: clearance (> 75% improvement compared with the previous session), marked improvement (50-75%), partial improvement (25-50%), and no response (< 25%). RESULTS: The rate of clearance plus marked improvement (favorable outcome) was 66.1% for telangiectasia group, 93.5% for Spider Angioma group, and 26.7% for erythema group. Mean number of treatments was 2.9 +/- 1.4 for telangiectasia group, 1.4 +/- 0.8 for Spider Angioma group, and 2.9 +/- 1.7 for facial erythema group. Only minimal adverse effects related to treatment procedure were detected in 5 out of 146 (3.4%) patients. CONCLUSIONS: Our results demonstrated that KTP laser might be a safe and effective laser modality for SCVLs, which may be associated with physiological problems due to cosmetic concerns
