About this study

Official title: Prospective, Single-centre Post-Market Clinical Follow-up (PMCF) Study to Evaluate Safety and Performance of the DUO Venous Stent

This observational study is to evaluate performance and safety of the DUO Venous Stent for the treatment of obstructions of the iliac vein.

Venous stent system

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary patency rate at month 12

    The primary patency rate is defined as the percentage of stented target lesions with primary treatment success and without the occurrence of thrombosis of the treated lesion or any re-intervention (surgical interventions on the target vessel) to restore or maintain flow within the treated lesion

    Measured: 12 months

Secondary outcomes (7)
  1. Primary patency rates

    Measured: 30 Days, 6 and 24 months

  2. Secondary patency rates

    Percentage of patients with primary treatment success and without occurrence of permanent loss of flow in the treated segment, irrespective of any reintervention

    Measured: 30 Days, 6, 12 and 24 months

  3. Revised Venous Clinical Severity Score (VCSS)

    The score includes 10 clinical parameters (pain, varicose veins, venous edema, skin hyperpigmentation, inflammation, induration, number of ulcers, durations of ulcers, size of ulcers, and compliance with compression therapy). Each item is graded from zero to three depending on severity (None = 0, Mild = 1, Moderate = 2, Severe = 3).

    Measured: 30 Days 6, 12 and 24 month

  4. Clinical Etiological Anatomical Pathophysiological Classification score (CEAP)

    The score for the clinical condition of the chronic venous insufficiency (C0 to C6) will be evaluated whereas C0 is representing the best and C6 the worst condition

    Measured: 30 Days, 6, 12 and 24 months

  5. Villalta score

    The score includes five symptoms (pain, cramps, heaviness, paresthesia, pruritus) and six clinical signs (pretibial edema, skin induration, hyperpigmentation, redness, venous ectasia, pain on calf compression).Each item is graded from zero (not present)to three (severe).

    Measured: 30 Days, 6, 12 and 24 month

  6. Device or procedure-related adverse events

    Measured: 30 Days, 6, 12 and 24 month

  7. Serious adverse events

    Measured: 30 Days, 6, 12 and 24 month

Questions about this trial

What is this clinical trial studying?

An observational study of Deep Venous Obstructions, run by Klinikum Arnsberg at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Michael Lichtenberg, MD (+49 02923 952 242 ext. 201, M.Lichtenberg@klinikum-hochsauerland.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary patency rate at month 12 (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 May 2022.
