Chronic Venous Insufficiency with Symptomatic Great Saphenous Vein Reflux in Adults: What to Do When Conservative Therapy Has Not Controlled Symptoms
This protocol covers adults with symptomatic great saphenous vein (GSV) reflux — with or without concurrent small saphenous vein (SSV) reflux — who have not achieved adequate relief of leg discomfort and edema on conservative management.
Clinical scenario: Adults with symptomatic GSV reflux, with or without SSV reflux, in whom a prior course of conservative therapy has not met the target goals of reduced leg discomfort and reduced volume of edema.
Previous line — goals not met
Conservative therapy — comprising compression therapy, venotonic medications, lifestyle changes, and weight loss where applicable — was the initial approach. This protocol is indicated when that line has failed to achieve reduced leg discomfort and reduced volume of edema.
Next-step approach
When conservative therapy has not controlled symptoms, an ablation-based intervention targeting the great saphenous vein, combined with continued conservative management, is the recommended next step — the specific modality and full treatment sequence are detailed in the structured protocol.
Complete modality selection guidance, criteria for below-knee segments, and the full clinical algorithm are available behind the link below.
Treatment success is assessed by improvement in venous symptoms at 6 weeks and a reduction in time to ulcer healing where applicable.

- For patients with symptomatic GSV with or without SSV reflux, the SCAI guideline panel suggests ablation therapy plus conservative management rather than conservative management alone (conditional recommendation, low certainty of evidence).
- Ablation therapy can be divided into thermal and nonthermal modalities.
- Nonthermal ablation modalities include mechanochemical ablation, cyanoacrylate adhesive ablation, and foam sclerotherapy.
- Additionally, nonthermal ablation may be preferred to reduce the risk of nerve injury that can occur, particularly with ablations below the knee and to the SSV.
