Endovenous treatment of varicose veins, especially thermal procedures using laser and radio frequencies, has become established as an effective alternative to surgery by stripping and high ligation. Although these methods are very sparing and patient-friendly, they also entail risks and side effects. The risk of damage to peripheral and motor nerves is certainly lower than with open surgery, however it still exists as a result of heat application and tumescent anaesthesia. Several non-thermal procedures which do not require the use of tumescent anaesthesia are coming onto the market. They carry a significantly lower risk of nerve lesions while remaining highly effective. The present work analyses the current state of knowledge on the latest to be developed, cyanoacrylate adhesion of incompetent saphenous veins.
