Studiebefolkning

Subjects currently enrolled in both arms of the VeClose Study (NCT01807585) will be assessed for eligibility to enroll in the VeClose Five Year Follow-up Extension Study. All subjects must meet the inclusion criteria and must not meet the exclusion criteria. Assessment of eligibility is based on data available to the investigator at the time of subject enrollment. The subject will be considered to be enrolled in the VeClose Five Year Follow-up Extension Study after the informed consent is signed/dated and all of the study eligibility criteria have been met.

Kohorter og interventioner

Gruppe / kohorte
Intervention / Behandling
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).
Enhed: VenaSeal SCS
Ikke-tumescerende, ikke-termisk, ikke-skleroserende procedure, der bruger et proprietært medicinsk klæbemiddel leveret endovenøst ​​til at lukke venen.
Andre navne:
  • VenaSeal Sapheon lukkesystem
  • VSCS
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).
Enhed: Lukning Hurtig radiofrekvensablation (RFA)
Radiofrekvens termisk ablation af GSV ved hjælp af Covidien ClosureFast-systemet.
Andre navne:
  • Lukning Hurtig
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.
Enhed: Roll-In (VenaSeal SCS)
Non-tumescent, non-thermal, non-sclerosant procedure that uses a proprietary medical adhesive delivered endovenously to close the vein.
Andre navne:
  • VenaSeal Sapheon lukkesystem
  • VSCS
  • Rulle ind

Foranstaltningsbeskrivelse
Tidsramme
Complete Closure of the Target Vein at 5 years after index treatment in the VeClose study (NCT01807585).
Tidsramme: 5 years
Complete closure is defined as Doppler ultrasound examination showing closure along entire treated target vein segment with no discrete segments of patency exceeding 5cm.

Foranstaltningsbeskrivelse
Tidsramme
Venous Clinical Severity Score (VCSS)
Tidsramme: 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)
Tidsramme: 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)
Tidsramme: 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")
Tidsramme: 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
Tidsramme: 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
Tidsramme: 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
Tidsramme: 5 years
Details of adjunctive procedures performed on the study limb will be captured on Case Report Forms (CRFs)
