Objective: To compare long term outcomes after great saphenous vein (GSV) treatment with three radiofrequency (RF) thermal devices: Venefit (Closurefast), Radiofrequency Induced Thermal Therapy (RFITT), and Endovenous Radiofrequency (EVRF).

Design: A 72 month follow up of patients who were treated in the randomised 3RF study.

Methods: A total of 172 participants from the 3RF study were invited to take part in a single visit, long term, follow up study.

Objective: To compare the outcomes of ultrasound guided foam sclerotherapy (UGFS) and endovenous laser ablation (EVLA) to treat isolated small saphenous vein (SSV) incompetence in a multicentre randomised controlled study (RCT; ClinicalTrials.gov identifier: NCT05468450).

Methods: Patients aged ≥ 18 years undergoing isolated SSV treatment (reflux > 0.

Importance: One-year outcomes from the Early Venous Reflux Ablation (EVRA) randomized trial showed accelerated venous leg ulcer healing and greater ulcer-free time for participants who are treated with early endovenous ablation of lower extremity superficial reflux.

Objective: To evaluate the clinical and cost-effectiveness of early endovenous ablation of superficial venous reflux in patients with venous leg ulceration.

Design, Setting, And Participants: Between October 24, 2013, and September 27, 2016, the EVRA randomized clinical trial enrolled 450 participants (450 legs) with venous leg ulceration of less than 6 months' duration and superficial venous reflux.

Objective: Published in July 2013, National Institute for Health and Care Excellence Clinical Guideline 168 (CG168) recommended that people with bleeding varicose veins be referred immediately to a vascular service. We have examined the impact of CG168 on referral practice for patients with bleeding varicose veins from primary to secondary care in a local National Health Service setting.

Methods: Referrals to a local vascular service in the 6 years before (group 1) and 6 years after (group 2) publication of CG168 were analyzed to assess patients' management after a bleed, with particular reference to a patient's initial presentation and delays in referral to the vascular service.

Objectives: Venous thromboembolism is a potentially fatal complication of superficial endovenous treatment. Proper risk assessment and thromboprophylaxis could mitigate this hazard; however, there are currently no evidence-based or consensus guidelines. This study surveyed UK and Republic of Ireland vascular consultants to determine areas of consensus.

Objective: To date there has been no comparison of outcomes of endovenous radiofrequency (RF) devices. The 3-RF trial is the first randomised controlled trial of three commercially available RF ablation technologies.

Methods: Patients were recruited [182/302 patients with great saphenous vein (GSV) incompetence] into a prospective double blind randomised trial of Venefit, radiofrequency induced thermal therapy (RFITT), and endovenous radiofrequency (EVRF).

Background: Venous ulceration is a common and costly health-care issue worldwide, with poor healing rates greatly affecting patient quality of life. Compression bandaging has been shown to improve healing rates and reduce recurrence, but does not address the underlying cause, which is often superficial venous reflux. Surgical correction of the reflux reduces ulcer recurrence; however, the effect of early endovenous ablation of superficial venous reflux on ulcer healing is unclear.

Background: Thermal ablation, usually performed with tumescent local anaesthesia (TLA), is the preferred method for varicose veins treatment. Tumescent local anaesthesia is always cited; however, little detail of the procedure is presented in publications. This retrospective audit of clinical tumescent local anaesthesia practice aims to provide detailed information on an important aspect of endovenous practice.

Background: Venous disease is the most common cause of leg ulceration. Although compression therapy improves venous ulcer healing, it does not treat the underlying causes of venous hypertension. Treatment of superficial venous reflux has been shown to reduce the rate of ulcer recurrence, but the effect of early endovenous ablation of superficial venous reflux on ulcer healing remains unclear.

Scope Of The Review: This article systematically reviews the practice of radiofrequency ablation of lower limb varicose veins. We present the clinical evidence and best practice techniques for currently available devices.

Methods: Manufacturer's instructions-for-use were requested for all radiofrequency devices.

Objective: To report a case of femoral vein thrombosis in a carpet fitter and to highlight this as an occupational hazard.

Method: Case presentation and literature review.

Results: An otherwise fit 21-year-old carpet fitter with no past medical history presented with acute thrombosis of his left common femoral, superficial femoral and great saphenous veins.
