Ontwerpdetails
Cohorten en interventies
Groep / Cohort |
Interventie / Behandeling |
|---|---|
|
Experimental: VenaSeal SCS
Endovenous delivery of VenaSeal Adhesive (VA) to a target site in diseased great saphenous veins (GSV).
The VA is dispensed in small amounts with each pull of the trigger equaling 0.10 cc.
Subjects were randomized in a 1:1 ratio to either VenaSeal SCS or to RFA at the time of enrollment into the VeClose study (NCT01807585).
|
Niet-tumescente, niet-thermische, niet-scleroserende procedure waarbij gebruik wordt gemaakt van een gepatenteerde medische kleefstof die endoveneus wordt aangebracht om de ader te sluiten.
Andere namen:
|
|
Active Comparator: RFA
Endovenous insertion of the ClosureFast radiofrequency ablation (RFA) catheter into a target site in diseased great saphenous veins (GSV).
Heat is applied to the target vein using radiofrequency energy to ablate the target vein.
Subjects were randomized in a 1:1 ratio to either VenaSeal SCS or to RFA at the time of enrollment into the VeClose study (NCT01807585).
|
Radiofrequente thermische ablatie van de GSV met behulp van het Covidien ClosureFast-systeem.
Andere namen:
|
|
Experimental: Roll-in (VenaSeal SCS)
Prior to initiation of the randomized cohort at each site for the VeClose study (NCT01807585), a non-randomized cohort of 2 subjects per site (roll-in phase) were enrolled and treated with VenaSeal SCS with endovenous delivery of VenaSeal Adhesive (VA) to a target site in diseased great saphenous veins (GSV).
The VA is dispensed in small amounts with each pull of the trigger equaling 0.10 cc.
|
Non-tumescent, non-thermal, non-sclerosant procedure that uses a proprietary medical adhesive delivered endovenously to close the vein.

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Complete Closure of the Target Vein at 5 years after index treatment in the VeClose study (NCT01807585).

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Venous Clinical Severity Score (VCSS)
Tijdsspanne: 5 years
|
Change in Venous Clinical Severity Score (VCSS) at 5 years as compared to baseline data from the VeClose study (NCT01807585).
The VCSS is an Investigator assessment of the severity of venous reflux disease, assessing signs and symptoms such as pain, varicose veins, venous edema, skin pigmentation, induration and inflammation.
The VCSS score is the sum of responses to 10 questions.
Each question has a total possible of 3 points, which are then added for each question.
The overall VCSS scores can therefore range from 0 (no venous disease) to 30 (severe venous disease).
High scores indicate worse outcomes and "0" is the best possible outcome.

5 years
|
|
Aberdeen Varicose Vein Questionnaire (AVVQ)
Tijdsspanne: 5 years
|
Change in Aberdeen Varicose Vein Questionnaire (AVVQ) at 5 years as compared to baseline data from the VeClose study (NCT01807585).
AVVQ is a disease-specific 13-item questionnaire used to assess the impact of varicose veins on the quality of life, such as pain caused by varicose veins, and need to take painkilling tablets for varicose veins as well as assessing the presence of signs/symptoms such as ankle swelling, purple discoloration and rash/eczema.
The total score of AVVQ is the sum of all questions for each leg.
Scores range from 0 (no disease) to 100 (maximal disease).
High scores indicate worse outcomes and "0" is the best possible outcome.
|
5 years
|
|
Quality of Life survey (EQ-5D)
Tijdsspanne: 5 years
|
Change in Quality of Life survey (EQ-5D) at 5 years as compared to baseline data from the VeClose study (NCT01807585).
EQ-5D is a short generic quality of life survey that is commonly used outside of the United States for health technology assessments.
The "health state today" question provides an overall assessment along a 20-cm visual analog scale (VAS) with a range from 0 ("worst imaginable health state") to 100 ("best imaginable health state").
|
5 years
|
|
CEAP classification ("clinical, etiology, assessment and pathophysiology")
Tijdsspanne: 5 years
|
Standardized measure of the degree of venous insufficiency and secondary manifestations of venous disease as measured by the treating physician.
|
5 years
|
|
Satisfaction with Treatment
Tijdsspanne: 5 years
|
Satisfaction with Treatment assessment consists of a brief 2-question patient survey rating satisfaction with treatment provided and whether the subject would undergo the assigned treatment again.
The number (percent) of subjects on each level of satisfaction are summarized (Very satisfied, Somewhat satisfied, Somewhat dissatisfied, Very dissatisfied).
The number (percent) of subjects for the second satisfaction question, "would undergo treatment again" were also summarized by response (Definitely have again, Might have again, Not have again).
|
5 years
|
|
Adverse events (AE) related to the target GSV
Tijdsspanne: 5 years
|
AEs related to the GSV will be tabulated and reporting using the MedDRA dictionary, version 16.1.
|
5 years
|
|
Adjunctive procedures performed on the study limb
Tijdsspanne: 5 years
|
Details of adjunctive procedures performed on the study limb will be captured on Case Report Forms (CRFs)
