Spider veins (telangiectasias) are small, visible blood vessels that may appear red, purple or blue, commonly on the legs or face. They are often a cosmetic concern, but visible leg veins can sometimes occur together with larger reticular or varicose veins. For this reason, assessment is important before deciding whether laser treatment is appropriate.
What Are Spider Veins?
Spider veins are small dilated superficial blood vessels visible through the skin. They may develop for several reasons, including genetic tendency, hormonal factors, pregnancy, prolonged standing, age and changes in the superficial venous system. Their appearance alone does not determine the most appropriate treatment.
Selected superficial vessels can be treated with vascular laser. Laser energy is absorbed by hemoglobin within the targeted blood vessel, producing controlled heating that can cause the vessel to gradually close and become less visible. Response varies according to vessel size, depth and color, treatment area, skin type and individual factors.
Laser may be considered for selected small superficial vessels after assessment. Long-pulsed 1064 nm Nd:YAG laser is one established option for leg telangiectasias and small reticular veins. Treatment choice should be individualized; laser is not automatically the appropriate treatment for every visible vein.
When Is Further Vascular Assessment Important?
Prominent varicose veins, leg swelling, persistent aching or heaviness, skin changes, recurrent inflammation, or other features suggesting underlying venous disease may require further medical or vascular assessment. Treating a visible vessel does not treat an underlying venous disorder when one is present.
The area is assessed and appropriate laser parameters are selected according to the vessel and skin characteristics. Protective eyewear is used during treatment. Patients may feel brief heat, stinging or discomfort as individual vessels are treated. The duration depends on the number and size of the vessels.
There is no fixed number for every patient. Some vessels may improve after one treatment, while others require additional sessions. Complete clearance cannot be guaranteed, and new spider veins may develop over time.
Temporary redness, swelling, tenderness, bruising or darkening of the treated vessels may occur. Less commonly, blistering, pigment changes, crusting or other skin reactions can occur. Individual risks depend on the treatment area, skin type and laser parameters. Appropriate aftercare and sun protection are …
