  1. Inflammation may occur in the treated area: This will apear as redness of the skin and if blood is stilll trapped in the veins, the veins may be raised and red – this will all resolve over time.
  2. There may be small ulcerations if any sclerosant extravasated outside the vein.
  3. There may be darker lines where the veins were  (hyperpigmentation).
  4. There may be matting of the treated veins.
  5. There may some nerve damage – numbness or pain.
  6. These all normally resolve over a few days to a few weeks.
  7. Other complications, that are rarer but may require intervention are:

  • Blood clots – if the vein was large some blood may become trapped and this may need to be drained with a tiny incision.
  • Deep vein thrombosis – extremely rare.
  • More extensive inflammation – may require an anti-inflammatory or an antibiotic if there is secondary infection.
  • Allergic reaction – this is very uncommon, is treated on it merits and would prevent the same sclerosant being used again.
  • Air bubbles in foam sclerotherapy – tiny air bubbles may enter the blood stream and cause no problems at all, but they may also result in nausea, visual disturbances, migraine and some neurological abnormalities. These are usually temporary but any neurological abnormalities should be reported.
