A New Method of Surgically Treating Varicose Veins and Venous Ulcers - a Study to Assess Clinical and Economic Value
A Dual Centre, Randomised Controlled Trial of the Clinical and Cost Effectiveness of Endovenous Laser Therapy (EVLT) in the Treatment of Varicose Veins and Venous Ulcers
Varicose veins are a common problem, affecting up to a third of the western adult population. Most suffer with aching, discomfort, pruritis, and muscle cramps, whilst complications include oedema, eczema, lipodermatosclerosis, ulceration, phlebitis, and bleeding. This is known to have a significant negative effect on patient's quality of life (QoL).
Surgery has been used for many years, but it is known that there is a temporary decline in QoL post-op. This was demonstrated in our pilot study. Surgery leads to painful and prolonged recovery in some patients and has the risks of infection, haematoma and nerve injury.
Recurrence rates are known to be significant. Duplex of veins post surgery has demonstrated persistent reflux in 9-29% of cases at 1 year, 13-40% at 2 years, 40% at 5 years and 60% at 34 years.
26% of NHS patients were 'very dissatisfied' with their varicose vein surgery.
Newer, less invasive treatments are being developed. It would be advantageous to find a treatment that avoided the morbidity of surgery, one that could be performed as a day-case procedure under a local anaesthetic, a treatment that could offer lower recurrence rates and allow an early return to work. These should be the aims of any new treatment for varicose veins.
Endovenous Laser Treatment (EVLT) is performed under a local anaesthetic and uses laser energy delivered into the vein to obliterate it. The vein therefore need not be tied off surgically and stripped out.
The aim of this study is to compare the clinical, cost effectiveness and safety of Surgery and EVLT.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Surgery
|
Patients undergo Saphenofemoral ligation, inversion stripping of the Long Saphenous Vein and avulsion of varicosities if necessary under a general anaesthetic.
|
Experimental: EVLT
|
Patients undergo endovenous laser treatment, using a 810nm laser aiming to occlude the incompetent long saphenous vein from the saphenofemoral junction to the knee.
This may then be followed by ambulatory phlebectomy as appropriate.
All procedures are to be performed under a local anaesthetic.

A detailed clinical and duplex ultrasound assessment was undertaken to identify: The presence of residual or recurrent varicose veins (defined as clinically evident varicose veins of greater than 3mm in diameter present at 1 and 6 weeks (residual) or becoming evident only after 6 weeks (recurrent). This was irrespective of the presence or absence of symptoms. The pattern of underlying insufficiency on duplex giving rise to any clinically evident varicose veins or skin changes. |
