The New 940 nanometer Diode Laser Effective Treatment For Leg Venulectasia


Leg telangiectases are represented by an expanded venule, capillary, or arteriole. The clinical aspects and physiopathology are quite different within each variety of telangiectases. Color,depth, diameter, and placement define the various categories of telangiectases.1-3 Superficial telangiectasia,venulectasia, and reticular veins measuring,respectively, 0.1 to 0.3 mm, 0.4 to 2 mm, and 2 to 4 mm in diameter represent 3 distinct target vessels.Treatment strategy must be modified to achieve greater success. Sclerotherapy combined with a variety of agents is considered the gold standard treatment for leg telangiactasias. However, pain, pigment changes, ulceration, scarring, and telangiectatic matting may result.


Since the development of laser technology in dermatology, vascular indications such as port wine stains or spider angioma have been treated successfully.As an alternative method, leg telangiectases were also treated.


The Cherylas laser in a repetitive pulse with an optical fiber ( core size 600 µm) ending with a hand piece (probe) were used to treat the spider veins in a (non contact) technique of (2mm) away from the skin. The tip of optical fiber was held perpendicular to the skin and moved in a low speed at a rate of (1cm/min). The total exposure time for each patient was entirely dependent on the length of spider veins under treatment.

High absorption 532 nm treatments are preferred for smaller and more superficial vessels. Superficial and small-diameter vessels are most selectively treated with wavelengths that are strongly absorbed by oxyhemoglobin as the vessels can be heated to clinical response temperatures with minimal incident energy. However, high oxyhemoglobin absorption can limit the depth to which laser light penetrates into skin, making it difficult to treat large or deep vessels with these wavelengths.


Moderate absorption 940 nm treatments are preferred for larger and deeper vessels. Less strongly absorbed wavelengths penetrate more deeply, and can more uniformly heat through larger diameter vessels. Higher fluences are used to overcome the lower absorption coefficient and successful treatments can be achieved with good selectivity. Of the near infrared wavelengths, 940 nm is optimal since it has the highest oxyhemoglobin absorption coefficient for improved selectivity, reduced discomfort, and fewer side effects.


What conditions are treated?

Vascular Lesions:

• Facial telangiectasia – surface veins caused by dilation of capillary vessels

• Cherry angiomas – slightly raised, red lesions

• Spider angiomas – slightly raised, red spider-like lesions

• Rosacea – red facial lesions around the nose and cheeks causing a sunburned irritated look

• Spider veins – small, superficial purple or red veins stretching like a web under the skin


Pigmented Lesions:

• Lentignes – flat, brown spots on the skin, present on skin with frequent sun exposure

• Freckles – brown spots on the skin

• Dermatosis papulosis nigra – small black raised lesions seen primarily on people of Asian or African descent


Cutaneous Lesions:

• Keratoses - slightly elevated pigmented lesions often found on the back and hands
