Clinical Trial Summary

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.

Eligibility

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Binary restenosis	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	Device-related complications	Registration of peri- and early/late postoperative complications	up to 12 months follow-up
Secondary	Immediate procedural outcome	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
Secondary	Clinical outcome	Rutherford classification	at baseline
Secondary	Clinical outcome	Rutherford classification	at 6 weeks follow-up
Secondary	Clinical outcome	Rutherford classification	at 12 months follow-up
Secondary	Primary sustained clinical improvement	defined as sustained upward shift of = 1 category on Rutherford classification without the need for repeated TLR in surviving patients.	at 12 months follow-up
Secondary	Secondary sustained clinical improvement	defined as sustained upward shift of = 1 category on Rutherford classification including the need for repeated TLR in surviving patients.	at 12 months follow-up
Secondary	Target lesion revascularization (TLR)	defined as an endovascular or surgical treatment due to a problem arising from the lesion (+1cm proximally and distally to include edge phenomena).	up to 12 months follow-up
Secondary	Mortality	Procedure-related and all-cause mortality.	up to 12 months follow-up
Secondary	Amputation	minor amputation defined as below the ankle and major defined as above the ankle.	up to 12 months follow-up
