New, previously unnoticed veins after Sclerotherapy


This phenomenon of developing new, previously unnoticed veins after sclerotherapy is called telangiectatic matting. It has also been called FLARES and BLUSHING. There are many theories as to why telangiectatic mapping occurs and most relate to hypoxia, or low oxygen levels in the tissue.

It is believed to occur because of angiogenesis (creation of new vessels) or dilation of existing blood vessels. Probable risk factors for the development of telangiectatic mapping includes being overweight and obese, pregnancy state after sclerotherapy or vein surgery, and the use of estrogen in this time period. This matting typically appears within 4-8 weeks of sclerotherapy or vein stripping surgery.

Fortunately, for most patients, telangiectatic mapping disappears wihout treatment within 4 to 12 months. They disappear in more than 95% of patients at 1 year follow-up. Persistent telangiectatic mapping can be treated with laser or IPL treatment.
