Ultrasound guided foam sclerotherapy for varicose veins
The aim of ultrasound-guided foam sclerotherapy for varicose veins is to damage the endothelial surface of the vein causing scarring and leading to blockage of the treated varicose veins
- sclerosant, in the form of a foam, is intended to have good surface area contact with the vein walls
- the procedure may be carried out with local anaesthesia
- sclerosant foam is injected into the affected veins using ultrasound guidance
- the foam causes an inflammatory reaction in the vein wall, blocking the vein
- compression bandages are applied after the procedure and are typically worn for between a week and a month
- more than 1 vein may be treated during the same session
- if any vein is incompletely treated, further injections may be given in the same or subsequent sessions
- sclerosant foam is injected into the affected veins using ultrasound guidance
NICE state that "..Current evidence on the efficacy of ultrasound-guided foam sclerotherapy for varicose veins is adequate" (1)
