What are potential side effects and complications of sclerotherapy?
In some patients treated with sclerotherapy, dark discoloration of the injected area may occur (hyperpigmentation). This usually happens because of disintegration of the red blood cells in the treated blood vessel. In the majority of cases, this discoloration will completely go away within 6 months.
Another potential problem is the formation of new spider veins near the area that was treated with sclerotherapy. This can happen in some patients, but these new vessels also typically disappear within 6 months.
Rare complications may include the formation of an ulcer around the injection site or the formation of small blood clots in the small surface veins (superficial thrombophlebitis).
