BackgroundEndovenous treatment of varicose veins has increased in popularity over the last decade. There remains, however, a degree of uncertainty regarding the role of compression bandaging or hosiery following this intervention. The National Institute for Clinical Excellence Guideline Development Group has advocated further research to evaluate the clinical and cost-effectiveness of this post-procedure intervention. In addition to this, the duration of compression bandaging also warrants clarification.MethodsEthical approval for the study was obtained from the Singhealth Centralised Institutional Review Board (CIRB Ref: 2017/2710). Consent to enter the study will be sought from each participant only after a full explanation has been given, an information leaflet offered and time allowed for consideration. Signed participant consent will be obtained. Patients will be randomised to either compression (group A) or no compression (group B). The primary aim of the study is to assess the patient’s pain scores for the first 10 days post procedure using a visual analogue scale. Secondary aims include an assessment of patient compliance with compression, quality of life scores, clinical effectiveness, rates of bruising and phlebitis, time taken to return to normal activities, patient satisfaction and occlusion rate at 6 months.DiscussionThe purpose of this study is to examine the effect of compression therapy in patients having mechano-chemical ablation (MOCA) therapy for truncal incompetence of their varicose veins using the ClariVein® device. This study may provide clarification on the role of compression therapy in patients undergoing MOCA.Trial, NCT03685838. Registered on 26 September 2018.
