Plain English Summary
Background and study aims
Leg compression after heat treatment of swollen or enlarged veins is used to reduce the procedure-related side-effects. There is not enough evidence to lend support to the use of leg compression. The aim of this study is to investigate whether leg compression is needed after heat treatment of varicose veins.
Who can participate?
Individuals with enlarged or swollen veins referred to clinics at Royal Bolton Hospital (UK)
What does the study involve?
Patients will be randomly allocated to heat treatment of their veins followed by leg compression or no leg compression.
What are the possible benefits and risks of participating?
Benefits are a reduction in the occurrence of blood clots in veins, pain and inflammation. Risks might be discomfort associated with limb compression and movement restriction.
Where is the study run from?
Royal Bolton Hospital NHS Foundation Trust (UK)
When is the study starting and how long is it expected to run for?
From February 2015 to February 2016
Who is funding the study?
Royal Bolton Hospital NHS Foundation Trust (UK)

Primary outcome measures
Successful obliteration of target vein, assessed with duplex ultrasound scan at 12–14 weeks
Secondary outcome measures
1. Quality of life, assessed with the Aberdeen Varicose Vein Severity Score and the Venous Clinical Severity Score at baseline (on the day of surgery) and at 12 weeks
2. Complications: recorded during patients' follow-up or emergency admissions, including any problems specifically related to stockings from the first post-operative day to 12 weeks
3. Patient's satisfaction, assessed with a patient satisfaction questionnaire
4. Pain, measured with the Visual Analogue Scale questionnaire; completed by the patient during the first post-operative week and collected at the 2 week review
5. Return to normal activities: information obtained by direct questioning at the 2 week interview and reconfirmed at 12 weeks
