A synopsis of current international guidelines and new modalities for the treatment of varicose veins.

BACKGROUND: The UK National Institute for Health and Care Excellence released new guidelines in 2013 recommending that endovenous thermal ablation (laser or radiofrequency) and ultrasound-guided foam sclerotherapy should be offered before conventional surgery for treat-ment of varicose veins and saphenous vein reflux.

OBJECTIVE: The aim of this article is to provide a synopsis of current international guidelines and recent advances for the treatment of varicose veins.

DISCUSSION: Conventional surgery involving classical high ligation and stripping of the saphenous vein has been standard practice for nearly a century. Surgery requires general anaesthesia and hospitalisation, and there is a high rate of recurrent disease. In the past decade there has been an international trend where the minimally invasive techniques of endovenous thermal ablation and ultrasound-guided foam sclerotherapy, which do not require hospitalisation, are beginning to displace surgery. These changes in technique have been supported by recently published international guidelines.
