These are superficial varicosed veins that lie just beneath the skin. They occur when the walls of a vein are weak or damaged or if the valves in the vein that normally stop the blood from flowing backwards are impaired, resulting in pooling of the blood and stretched veins. Besides being unattractive, varicose veins can be painful and cause inflammation or ulceration.
The following different types of surgery are available if varicose veins require treatment:
- Sclerotherapy – a tiny needle is used to inject a chemical solution into the vein that causes the vein to collapse. This approach is recommended for small varicose veins or spider veins that typically appear on the thigh or lower legs. You will need to wear elastic stockings over the treated area for two weeks afterwards and walk with the stockings on for half an hour per day for those two weeks.
- Laser ablation
- Operation - the latter two are best done by a trained vascular surgeon or general surgeon.
