Endovascular Treatment of Peripheral Artery Disease (PAD)

September 2, 2024 updated by: Duomed

Endovascular Treatment of Peripheral Artery Disease.

The purpose of this observational study is to evaluate the performance and safety of endovascular treatment with stenting (Optimed Sinus Superflex 635 or Qualimed Pontos-pp) or balloon angioplasty (Cardionovum Legflow or Optimed Nylotrack .035 + .018) according to current practice. The goal of the study will be achieved by assessing binary restenosis with duplex ultrasound, peri- and postoperative complications, technical success, target lesion revascularization, amputation and clinical outcome.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with peripheral artery disease, located in the common and external iliac artery, the common and superficial femoral artery, the popliteal artery and/or the below-the-knee (BTK) arteries (anterior tibial artery, posterior tibial artery or peroneal artery).

Description

Inclusion Criteria:

  1. Patient must sign the informed consent form prior to the index-procedure.
  2. Patient is older than 18 years.
  3. Patient is compliant with the requested follow-up visits at week 6 and month 12 and the treatment regime.
  4. Patient suffers from mild to intermittent claudication (Rutherford 1-3) or critical limb ischemia (Rutherford 4-5).
  5. Target lesion is an occlusion or diameter stenosis is ≥50% by visual estimate.
  6. Target lesion is located in the common and external iliac artery, in the common and superficial femoral artery, popliteal artery and/or the below-the-knee (BTK) arteries (anterior tibial artery, posterior tibial artery or peroneal artery).

Exclusion Criteria:

  1. Patients with Rutherford 0 and 6.
  2. Patient is pregnant.
  3. Patients with estimated Glomerular filtration rate (eGFR) < 30 mL/min/1.73m2.
  4. Patient has an acute thrombus or aneurysm in the target arteries.
  5. Patient has a life expectancy of <12 months.
  6. Patient has a target lesion that cannot be crossed with a guidewire.
  7. Patient suffers from acute limb ischemia defined as any sudden decrease in limb perfusion causing a potential threat to limb viability.
  8. Patient has scheduled elective non-vascular procedures within 3 months after index-procedure. Vascular procedures are allowed within 3 months after the index-procedure if it is guaranteed that acetylic salicylic acid and clopidogrel intake is not interrupted.
  9. Contraindication for anti-thrombotic therapy (coagulopathy, …).
  10. Patient has a known intolerance to anti-thrombotic medication or contrast agents.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Binary restenosis
Time Frame: at 12 months follow-up
Binary restenosis defined as ≥ 50% re-obstruction of the target lesion will be assessed by duplex ultrasound (peak systolic ratio >2.4)
at 12 months follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Device-related complications
Time Frame: up to 12 months follow-up
Registration of peri- and early/late postoperative complications
up to 12 months follow-up
Immediate procedural outcome
Time Frame: during index-procedure
The combination of technical success defined as a successful access and deployment of the device and achievement of a final residual diameter stenosis of <30% of the treated target lesion on the procedural completion angiography and procedural success defined as a combination of technical success and absence of procedural complications.
during index-procedure
