Efficacy of the SALFOAM 3% Method Compared to the Conventional Polidocanol Foam Method (Tessari Method) for Treating Lower Limb Varicose Veins

This clinical trial aims to assess the efficacy and safety of the SALFOAM 3% method, which involves saline wash, polidocanol 3% foam injection, and extrinsic compression using Lidstop®, in comparison with the conventional Tessari method for the treatment of lower limb varicose veins. The primary objective is to determine whether the SALFOAM 3% method results in better or equivalent vein occlusion rates and fewer adverse effects, such as hyperpigmentation, compared to the standard treatment.

About this study

Chronic venous disease (CVD) is prevalent in approximately 38% of the adult population in Brazil, posing significant public health challenges due to its potential complications, including ulcerations and reduced quality of life. The SALFOAM 3% method is a novel approach that combines saline wash prior to polidocanol 3% foam sclerotherapy and extrinsic compression with Lidstop®, aiming to improve outcomes by reducing adverse effects such as hyperpigmentation and enhancing patient quality of life. This randomized controlled trial will compare the efficacy, safety, and quality of life outcomes of patients treated with the SALFOAM 3% method versus those treated with the conventional Tessari method for lower limb varicose veins.

Treatment and study plan

SALFOAM 3%

Procedure
  • Drug: Polidocanol 3%
  • Device: Lidstop®

Control Group

Procedure
  • Drug: Polidocanol 3%
  • Device: Standard compression with dental roll and elastic stockings

Primary outcomes

  1. Vein Occlusion Rate at 30 Days

    Time frame: 30 days post-procedure

    Vein occlusion will be measured using Doppler ultrasound to assess whether the treated veins are completely occluded, partially occluded, or not occluded at 30 days post-procedure.

Secondary outcomes

  1. Hyperpigmentation Rate

    Time frame: 7 and 30 days post-procedure

    Incidence of hyperpigmentation will be evaluated using a 4-point scale (1 = absent, 2 = mild, 3 = moderate, 4 = severe) at 7 and 30 days post-procedure.

Other outcomes

  1. Adverse Event Rate

    Time frame: 7 and 30 days post-procedure

    Incidence of adverse events, including thrombophlebitis, skin ulceration, and other complications, will be assessed through clinical and ultrasound evaluations.

  2. Quality of Life Improvement

    Time frame: 30 days post-procedure

    Measured using the revised Venous Clinical Severity Score (rVCSS) to assess changes in the quality of life of participants at 30 days post-procedure. The total score ranges from a minimum of 0 to a maximum of 30 for a single limb. Minimum score: 0. This indicates the complete absence of symptoms or signs for all 10 characteristics. Maximum score: 30. This indicates the most severe symptoms and signs across all 10 characteristics.
