About this study
Official title: Randomized Controlled Trial Comparing the Clinical Outcomes After Cyanoacrylate Closure and Surgical Stripping for Incompetent Saphenous Veins
The purpose of this study is to evaluate the non-inferior, clinical outcomes after cyanoacrylate closure comparing the surgical stripping for incompetent saphenous veins.
Read the detailed description
Varicose veins are highly prevalent. In western countries, an estimated 23% of adults have varicose veins, and 6% have more advanced chronic venous disease, including skin changes and healed or active venous ulcers. There are several modalities to treat varicose veins. Open surgical treatment with ligation and stripping of the saphenous vein, combined with excision of large varicosities, has been the standard of care for many years. Endovenous thermal ablation by radiofrequency ablation (RFA) or endovenous laser ablation (EVLA) has been shown to be a safe and effective alternatives with high long-term target vein closure rates. Although both techniques have gained broad acceptance in many countries, one major disadvantage of these techniques is the requirement for use of tumescent anesthesia to avoid the thermal injury of the surrounding structures. Cyanoacrylate closure for varicose veins has recently been introduced for treatment of the incompetent saphenous vein.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cyanoacrylate closureProcedure or surgery
Also called Cyanoacrylate closure for incompetent Saphenous vein
After successful access of target vein and insertion of guidewire under any type of anesthesia, the procedure of cyanoacrylate closure is performed. A 5 French introducer and catheter is advanced and positioned 5.0 cm caudal to the junction with proximal saphenous vein compression by the ultrasound probe, two injections of approximately 0.10 mL glue are given 1 cm apart, followed by a 3min period of compression, and then repeat injections and 30sec ultrasound probe and hand compression sequences until the entire length of the target vein is treated. The catheter is removed.
Surgical strippingProcedure or surgery
Also called Surgical stripping for incompetent Saphenous vein
All types of anesthesia (general, spinal, regional block, or local anesthesia) can be used. The surgical stripping is performed with a proper incision in the groin, with division and ligation of the saphenous vein and division of all tributaries. The saphenous vein is then removed using a stripper.

What is being measured
The primary outcome is the main question the study is designed to answer.
Closure rate of the target vein/ Absence of refluxing vein
The primary endpoint of the study is to evaluate the complete closure of the target vein where complete closure is defined as Doppler ultrasound showing vein closure along entire treated vein segment with no discrete segments of patency exceeding 5cm after cyanoacrylate closure and absence of refluxing vein or residual vein after surgical stripping as read by a qualified site technologist or investigator.
Measured: 3 months
Secondary outcomes (5)
Perioperative pain with visual analog scale
The subject will be asked to rate pain on a 0-10 numeric rating scale. (minimum-0 (best), maximum-10 (worst))
Measured: 3 days
Ecchymosis
The investigator will score the subjects ipsilateral leg of the occurrence of ecchymosis along treated segment, rated on a 0- to 5-point graded scale (0, none; 1, involving <25% of the treatment area; 2, 25%-50%; 3, 50%-75%; 4, 75%-100%; 5, extension above or below the treatment segment)
Measured: 3 days
Venous Clinical Severity Score
Severity score on a 0-30 numeric rating scale ((minimum-0 (best), maximum-30 (worst))
Measured: 1, 3, 6, 12 and 24 months after treatment
Acceptability of Quality of life score
The quality of life scores are measured by the Aberdeen Varicose Vein Questionnaire (AVVQ) and EuroQOL five dimensions questionnaire (EQ-5D).
The AVVQs are scored using a questionnaire. The total score for the 13 questions ranges from 0 to 100 points, with 0 points indicating the best possible quality of life. The EuroQOL is an instrument which evaluates the generic quality of life. The EuroQOL descriptive system is a preference-based measure with one question for each of the five dimensions that include mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Respondents can report their perceived health status with a grade ranging from 0 (the worst possible health status) to 100 (the best possible health status).
Measured: 1, 3, 6, 12 and 24 months after treatment
Satisfaction of the patients: satisfaction rate
The subject will be asked to the satisfaction rate by five response categories (strongly agree, agree, uncertain, disagree, strongly disagree) after asking as following: I'm very satisfied with the medical care I receive.
Measured: 1, 3, 6, 12 and 24 months after treatment

Questions about this trial
What is this clinical trial studying?
A study testing Cyanoacrylate closure and Surgical stripping in people with Occlusions Vein and Chronic Venous Insufficiency, run by Kyung Hee University Hospital at Gangdong at 2 sites in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 16 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Jin Hyun Joh, MD, PhD (+82-2-440-6261, vascularjoh@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Closure rate of the target vein/ Absence of refluxing vein (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03835559, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2019; AzTrials last refreshed its copy on 8 Nov 2026.
