Plain English summary of protocol

Background and study aims
Varicose veins are swollen and enlarged veins that usually occur on the legs. They can be treated with surgery to remove the affected veins or with thermotherapy, in which the affected veins are burned and closed. At the moment there is not enough evidence regarding the benefits of the different treatments for varicose veins, especially for thermotherapy. The aim of our study is to find out whether thermotherapy provides better results compared with surgery.

Who can participate?
Patients aged 18 - 70 with varicose veins.

What does the study involve?
Participants will be randomly allocated to undergo either thermotherapy or surgery. The participants will be followed-up regularly for 5 years after the treatment.

What are the possible benefits and risks of participating?
By entering the study participants get the chance to try a new treatment for free.

Where is the study run from?
Krankenhaus Tabea (Germany).

When is the study starting and how long is it expected to run for?
From November 2014 to October 2019.

Who is funding the study?
Artemed SE (Germany).

Who is the main contact?
Dr Guido Bruning

Scientific titleQuality of life and benefit for patients: bipolar radiofrequency-induced thermotherapy (RFITT) versus crossectomy and stripping: a prospective randomized multi-centre trial
Study acronymCelArt
Study objectivesQuality of life and benefit for the patient is higher 5 years after bipolar radio frequency induced thermotherapy (RFITT) compared with high ligation (crossectomy) and stripping.
Ethics approval(s)Medical Council of Hamburg (Ärztekammer Hamburg), Germany, approved 10/06/2014 (confirmed
amendments on 04/04/2014 and 13/05/2014), identification no. PV4495
Health condition(s) or problem(s) studiedGreat saphenous vein insufficiency
InterventionGroup A: ultrasound-guided bipolar radio frequency induced thermotherapy (RFITT) is performed under tumescent local anaesthesia. The additional phlebectomy of side branches is allowed.

Group B: High Ligation (Crossectomy) and Stripping (HLS): Standard surgical procedures are performed, consisting of transection of all groin tributaries, flush ligation of the saphenofemoral junction with resorbable sutures and neoreflux protection with a continuous stump suture, followed by invagination stripping of the great saphenous vein just below knee under tumescent local anaesthesia. The additional phlebectomy of side branches is allowed.
Intervention type
Primary outcome measureQuality of life, benefit for the patients and patients' satisfaction is measured using visual analogue scale (VAS) based questionnaires, pain scale according to VAS, Venous Clinical Severity Score (VCSS), Patient Benefit Index (PBI-v[prä] and PBI-v[post]) and Freiburger quality of life questionnaire for veins (FLAQvs) and open-ended questionnaire. Measured at preoperative visit and after 3 months, 1 year, 2 years, 3 years, 4 years and
5 years.
Secondary outcome measures1. Minor and major complications
2. Recurrent varices after treatment (REVAT) evaluated at 3, 6, 12, 24, 36, 48 and 60 months follow-up visit
Overall study start date10/11/2014
Completion date09/10/2019
