Treatment of Leg Telangiectasias Using a Long-Pulse Frequency-doubled Neodymium:YAG Laser at 532 nm

Abstract

The VersaPulse variable pulse width laser appears to be an effective modality for the treatment of leg telangiectasias. The relative lack of patient discomfort combined with a high degree of patient satisfaction may indicate a fairly high level of patient acceptance of this new form of therapy for the treatment of leg telangiectasias.

Pulsed Alexandrite Laser for the Treatment of Leg Telangiectasia and Reticular Veins

“…In recent years, a variety of lasers have been developed with the specific goal of treating leg telangiectasia. These include pulsed potassium titanyl phosphate lasers (532 nm), 6 flashlamp-pumped tunable pulsed dye lasers (585-600 nm), [7][8][9] and a noncoherent pulsed light source (515-1200 nm). 10 These devices have been most successful in the treatment of small-caliber red telangiectasia measuring less than 1.0 mm in diameter.…”

Retrospective clinical comparison of hemangioma treatment by flashlamp-pumped (585 nm) and frequency-doubled Nd:YAG (532 nm) lasers

“…Positive results have been described to date for the treatment of port wine stains and essential and leg telangiectasias with this laser type [10][11][12][13][14][15]. In this study, the side effect rate of the VersaPulse is evaluated as being low .…”

“…Due to a wavelength of 532 nm, which comes close to the absorption maximum of oxygenated hemoglobin, it targets small dermal vessels exactly as the FPDL does. In the treatment of superficial vascular skin lesions such as port wine stains and essential and leg telangiectasias, this laser has already proven itself to be an effective therapy method [10][11][12][13][14][15]. To compare both lasers directly, we examined and treated 50 infants with a total of 62 superficial infant hemangiomas over a period of 12 months.…”

New approaches to the treatment of vascular lesions

“…The treatment of leg veins by using small spot sizes and pulse durations of 10 ms or less have been mixed [10,11]. Recent results have been more promising by using larger spot sizes (3-5 mm) and pulse duration of 10 to 50 ms at fluences of 14-20 J/cm 2 .…”
