Changing to endovenous treatment for varicose veins: How much more evidence is needed?

Surgical ligation and stripping of varicose veins has been the accepted treatment for almost a century but within the last decade this has been challenged by endovenous thermal and chemical ablation methods. Surgery is not without significant complications including paraesthesia and has reflux recurrence rates of up to 54% at five years, even though it has been shown to provide significant health-related quality of life benefits cost-effectively. Ultrasound-guided foam sclerotherapy, endovenous laser ablation and radiofrequency ablation are all consistently proving to be at least as beneficial as surgery, without the same complications and with less post-procedure morbidity and more rapid recovery. This article presents a review of the latest published evidence and comparative analysis of vein surgery and it’s alternatives. Endovenous treatment under local anaesthesia in a clinic room or office-based setting is now being recognized internationally as an acceptable standard for dedicated venous practice in a cost-effective environment. Although more long-term comparative trials of these innovative methods compared with surgery are desirable, many centres are now conducting trials testing the latest endovenous device technologies with each other to support the development of contemporary pathways of care. Patients are entitled to a range of treatment strategies, particularly when complex and recurrent venous disease has such unacceptably high surgical complication and recurrence rates compared to endovenous alternatives. There is questionable logic in procrastinating until there is more convincing evidence. Now is the time for vascular surgeons to enhance their ultrasound skills and future-proof their venous practice for the benefits of patients and institutions.
