Vascular pigment laser 532 1064 evidence for Venous lake

Abstract summary (English) 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...

Evaluation Study, Journal Article

Abstract summary (English) BACKGROUND: Some venous lakes do not respond well to traditional vascular lasers. The Nd:YAG laser output at 1,064 nm is less well absorbed by hemoglobin but penetrates more deeply into tissue. OBJECTIVE: This study was undertaken to assess the effectiveness of the long-pulsed Nd:YAG on venous lakes.

Case Reports, Comparative Study, Journal Article

Abstract summary (English) Venous lake is a benign vascular malformation commonly seen in elderly patients, typically arising in sun-exposed areas of the body. Patients often seek treatment to prevent recurrent bleeding or because they find the lesion cosmetically unacceptable. Venous lake may negatively affect quality of life, due to the cosmetic disfigurement it can create and the resulting psychological distress.

Abstract summary (English) BACKGROUND AND OBJECTIVE: The pulsed dye laser was developed based on the concept of selective photothermolysis. By using a wavelength of light well absorbed by the target and pulse duration short enough to spatially confine thermal injury, specific vascular injury could be produced. STUDY DESIGN/MATERIALS AND METHODS: Although the pulsed dye laser revolutionized the treatment of port wine stains (PWS) and a variety...

Abstract summary (English) OBJECTIVES: Varices and ectasias in singers are typically the result of phonotraumatic shearing stresses and/or collision forces on the microcirculation within the superficial lamina propria. These lesions can be debilitating in performing vocalists because of the effect of recurrent hemorrhage and/or as a contributing factor to the morbidity of other mass lesions such as polyps, nodules, and cysts....

Abstract summary (English) Although used for treating vascular malformations, KTP (532 nm) lasers have not been used to treat microvascular lesions of the vocal fold. The efficiency of KTP laser operation in the continuous mode with a 0.4- or 0.6-mm beam (1- to 2-W aim for 3 to 7 seconds delivering a total energy of 3 to 7 J) was studied retrospectively in patients with microvascular lesions of the vocal fold (n = 14). The perceptual...

Abstract summary (English) BACKGROUND: The long-pulsed Nd:YAG (1064 nm) laser has been shown to be effective in the treatment of blue venulectasias and reticular veins. OBJECTIVE: The present study examined the clinical efficacy and long-term follow-up (12 months) of patients treated with the 1064 nm Nd:YAG laser technology. METHODS: Twenty-five female patients (mean age 37.6 years, Fitzpatrick skin types II-V) were treated with up to three...

Journal Article

Abstract summary (English) Leg venectasia is a common problem. Although there are a variety of therapeutic modalities, none of them gives satisfactory results. The effects of sclerotherapy in the treatment of telangiectasia with a small diameter are poor.
