Detalles de diseño

Cohortes e Intervenciones

Grupo / Cohorte
Intervención / Tratamiento
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).
Procedimiento no tumescente, no térmico, no esclerosante que utiliza un adhesivo médico patentado que se administra por vía endovenosa para cerrar la vena.
Otros nombres:
  • Sistema de cierre VenaSeal Sapheon
  • 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).
Ablación térmica por radiofrecuencia de la GSV mediante el sistema Covidien ClosureFast.
Otros nombres:
  • CierreRápido
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.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Complete Closure of the Target Vein at 5 years after index treatment in the VeClose study (NCT01807585).
Periodo de tiempo: 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.
5 years

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Venous Clinical Severity Score (VCSS)
Periodo de tiempo: 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)
Periodo de tiempo: 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)
Periodo de tiempo: 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")
Periodo de tiempo: 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
Periodo de tiempo: 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
Periodo de tiempo: 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
Periodo de tiempo: 5 years
Details of adjunctive procedures performed on the study limb will be captured on Case Report Forms (CRFs)
5 years
