NCT01406795

Brief Summary

To study the safety and efficacy of drug coated stents for the treatment of venous occlusions and stenoses in the lower extremity. The use of the device for the treatment of peripheral arterial disease is approved by the FDA, however, the use of the device in venous occlusions and stenoses, although performed by some practitioners, has not yet been studied in detail.

Outcome Measures

Primary Outcomes (3)

  • Stent Migration

    Stent migration is reported as the count of participants with stent migration within 1 month following stent placement.

    up to 1 month following the procedure

  • Stent Migration

    Stent migration is reported as the count of participants with stent migration within 1 year following stent placement.

    up to one year following the procedure 1 year

  • Primary Patency Rate

    Patency refers to whether the stent is unoccluded (open). Primary patency rate was defined as the count of participants with \>= 50% patency following initial stent placement, and is reported as the count of participants meeting this criteria.

    up to 1 year following the procedure

Secondary Outcomes (8)

  • Freedom From Device-related Amputation

    up to 1 year following the procedure

  • Assisted-primary Patency

    up to 1 year

  • Secondary Patency

    up to 1 year

  • Adverse Events

    up to two years 2 years

  • Decrease in Swelling of Affected Extremity

    up to 2 years

  • +3 more secondary outcomes

Study Arms (1)

Venous Stent Arm

EXPERIMENTAL

The study is a single treatment arm study and the venous stent will be placed in all eligible participants.

Device: Gore Viabahn Heparin Coated Stent

Interventions

For subjects deemed to be suffering from chronic venous insufficiency of the femoral or popliteal veins, a Gore Viabahn stent will be implanted during a venoplasty procedure to determine whether the vein will stay open.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient is at least 18 years old
  • Imaging confirmation of venous occlusion or stenosis (\>50%) involving the femoral, and/or popliteal veins
  • Obstructed vessel caliber can accommodate a 7FR System, from insertion site to target segment
  • Patient is able to read and answer a questionnaire in English

You may not qualify if:

  • History of life-threatening reaction to contrast material
  • Unwilling or unable to provide informed consent, or return for required follow-up evaluations
  • Participating in another investigational study that has not completed follow-up testing
  • Cannot receive outpatient anticoagulation such as LMWH and/or vitamin K antagonists (VKAs)
  • Absolute contraindication to contrast media or renal insufficiency (baseline creatinine \>2.0 mg/dL).
  • Either a history or presence of heparin-induced thrombocytopenia antibodies
