Study population

all potential subjects who are appropriate for study inclusion, i.e. subjects implanted with POLYTHESE® for at least one year, or with complete data to death. As the study explores real world data, there is no exclusion criteria for subjects and all subjects with POLYTHESE® implanted for at least one year and have not objected to the collect of their data will be included in the study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

Patients must meet the following inclusion criteria in order to be eligible for inclusion in the study:

- Patient has a minimum of 1-year post-operative follow-up data available, or complete data to death

What researchers measure

Primary outcomes

  1. Performance: Primary patency rate

    Patency rate

    Time frame: 1 year

  2. Safety : Mortality rate

    Time frame: 30 days

Secondary outcomes

  1. Procedural success rate

    Ability to use with no need for replacement by another device and, Effective vascular flow restoration after procedure and, In case of aneurysm, exclusion of aneurysmal portion after procedure.

    Time frame: 5 years

  2. Primary patency rate

    rate patency of the bypass graft without procedure or intervention of the conduit itself (except for occlusion)

    Time frame: 5 years

  3. Primary assisted patency rate

    defined as rate patency of the bypass graft with or without procedure or intervention of the conduit itself (except for occlusion) after device implantation

    Time frame: 5 years

  4. Secondary patency

    defined as rate patency of the bypass graft with or without procedure or intervention of the conduit itself for occlusion after device implantation

    Time frame: 5 years

  5. Device Failure

    * Uncontrolled blood leakage from device * Loss of structural integrity, e.g. rupture and/or exaggerated dilation (\> 50 %) * Occlusion of the device * Total or partial replacement of the device required

    Time frame: 5 years

  6. Mortality rate

    freedom % from death

    Time frame: 5 years

  7. Limb salvage rate

    defined as freedom % from target limb amputation

    Time frame: 5 years

  8. Adverse events

    any documented adverse events, including anticipated and non-anticipated adverse events

    Time frame: 5 years

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 25, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
