入选标准
- •Men and women; age 18 to 75 years
- •Bilateral incompetence of SFJ (reflux >1 second on duplex ultrasonography) associated with incompetence of the GSV in both legs
- •GSV diameter >5 mm measured from the superficial epigastric vein to 10 cm below the SFJ while in a standing position in both legs
- •Eligible to receive RFA treatment and Varithena® treatment
- •CEAP C2-C5 (inclusive)
- •Patient is participating in usual work and home activities with no changes anticipated for the duration of the study
- •Ability to comprehend and sign an informed consent and complete study questionnaires written in English
- •Ability to reliably use an electronic diary to record pain and analgesic/opioid use in accordance with the protocol
排除标准
- •Prior GSV treatment in either leg
- •Non-venous source of pain in either leg that could confound the results of the study
- •Use of chronic analgesic or opiate medications or medical history that could result in the regular use of pain medications during the study

- •Major surgery, prolonged hospitalization or pregnancy within 3 months of screening
- •Major co-existing disease (e.g., malignancy; pulmonary disease; renal or hepatic insufficiency; serious skin disease/condition that may compromise the ability of the patient to comply with the compression protocol, etc.)
- •Contraindications to Varithena® (e.g., acute thromboembolic disease) or RFA according to the manufacturer's prescribing information
- •Varithena® contraindication due to known allergy to polidocanol
- •RFA contraindication due to veins being too large

研究组 & 干预措施
Varithena®, then Radiofrequency Ablation
Varithena (polidocanol injectable foam) supplied as polidocanol solution 180 mg/18 mL (10 mg/mL) to be activated before use. Once activated, Varithena is a white injectable foam delivering a 1% polidocanol solution. Each milliliter of Varithena injectable foam contains 1.3 mg of polidocanol. Up to 5 mL per injection or 15 mL per treatment session could be used. This was followed by RFA treatment.
干预措施: Varithena® (Drug)

结局指标
主要结局
Pain
时间窗: 14 day average (0-100)
14-day average post-treatment pain using a VAS pain score. VAS pain score is an integer-valued, interval scale variable with range from 0 to 100 representing the spectrum from no pain to pain as bad as one can imagine.
次要结局
- Procedural Pain(immediately following procedure)
- Patient Preference(8 weeks)
