Study summary

The FLOWGRAFT post-market clinical follow-up study is undertaken to show the safety and performance of FlowWeave Bioseal, FlowNit Bioseal, FlowLine Bipore and FlowLine Bipore Heparin (combined named as Vascular Grafts) in the treatment of arterial diseases, such as dissection, aneurysm, intramural hematoma (IMH), penetrating aortic ulcer (PAU), contained rupture, stenosis in the aorta or peripheral arteries (lower limbs). This includes the use of FlowWeave Bioseal or FlowNit Bioseal for debranching of the head vessels in an alone standing procedure. Furthermore, it includes the use of the FlowLine Bipore and FlowLine Bipore Heparin Grafts as arterious-venous (AV) shunt.

Read the detailed description

In this study, patients who receive a Vascular Graft for the treatment of arterial diseases (aneurysm, PAU, IMH, dissection, stenosis) of the aorta or peripheral arteries (lower limbs) or as an AV shunt will be observed. This includes patients in whom the Vascular Grafts are used for debranching or reconstruction of the head vessels. Participating physicians will be asked to provide the observations, that were collected during routine care. Written informed consent, specifically allowing the use of clinical records for this observational study, will be obtained from every patient prior to data collection.

The period of data collection will be approximately 60 + 6 months (depending on the date of the last follow-up visit) from the date of intervention for each patient.

Study population

Male and female patients with arterial disease who are scheduled to be treated with a Vascular Graft according to the instructions for use and their physician's discretion in accordance with the inclusion and exclusion criteria.

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

  • Patient ≥ 18 years at time of written
  • Patient was selected for treatment with a commercially available Vascular Graft of JOTEC
  • Patient satisfies at least one of the following categories:

    • Acute (14 days) / subacute (15 - 90 days) dissection with double lumina in the aorta or peripheral artery / arteries (lower limb)
    • Chronic (>90 days) dissection with double lumina in the aorta or peripheral artery / arteries (lower limb)
    • Aneurysm in the aorta or peripheral artery / arteries (lower limb)
    • IMH in the aorta or peripheral artery / arteries (lower limb)
    • PAU in the aorta or peripheral artery / arteries (lower limb)
    • Contained rupture in the aorta or peripheral artery / arteries (lower limb)
    • Stenosis in the aorta or peripheral artery / arteries (lower limb)
    • Debranching of head vessels
    • AV shunt
  • Patient is willing and able to comply with all clinical study procedures and study visits.
  • Patient has given written informed consent to participate in the study.

Exclusion criteria

Exclusion Criteria:

  • Patient has any other medical, social, or psychological problem that in the opinion of the investigator preclude them from receiving this treatment, procedures, and evaluations pre- and post-procedure.
  • Patient is scheduled for reconstruction of the tibial artery
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Dec 2021 (actual). Primary completion is estimated for Oct 2024, 33 months after the start.

Of 100 observational studies under Vascular Diseases, half reached primary completion within 52 months of starting (the median), counting those still running; a quarter within 25 and three quarters within 128. This study's planned 33 months is below that.

How these figures are worked out, and which studies are left out of them.

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 May 19, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
