Sclerotherapy for Spider Veins

What is Sclerotherapy?

Sclerotherapy is the treatment of choice for eliminating “spider veins” (superficial telangiectasias) and small reticular veins (1-2mm in diameter). The treatment is minimally invasive. Polidocanol (Asclera™) is the primary sclerosing agent used at Craig Singer MD Dermatology. When Polidocanol is injected into the vein, the wall of the vein becomes irritated and inflamed leading to vessel wall breakdown. The injured vein is then removed by the body’s own healing mechanism over the several weeks to months, and eventually fades.  Bloodflow is then rerouted through healthier veins.
