Summary
In recent years, ultrasound-guided foam sclerotherapy has become a firmly established
treatment for varicose veins and offers many advantages compared with other ablation
procedures. It is used without any type of anaesthesia, as the procedure is painless
for the patient. By contrast, tumescent anaesthesia is required in thermal procedures,
in order to protect surrounding structures and prevent unwanted nerve damage. This
is not necessary with foam sclerotherapy.
Foam sclerotherapy is a rapid and simple treatment method for both large and small
varicose veins and can be performed in the practice examination room. After duplex
examination and detailed discussion of the treatment, the patient can be treated during
the same session. Furthermore, in addition to the standard indications, foam sclerotherapy
can also be used to treat recurrent varicose veins and tortuous vascular segments.
In recent years, other non-thermal techniques have been developed in addition to foam
sclero-therapy.
This article provides an overview of the position of foam sclerotherapy and the various
non-thermal ablation techniques with regard to their efficacy, safety and side effects.
