Brief Summary:
Prospective, multi-center 1:1 randomized trial to compare efficacy and safety of a stent-avoiding (using drug coated balloons) versus a stent-preferred (using drug eluting or interwoven stents) approach for treatment of complex femoropopliteal lesions TASC II (TransAtlantic Inter-Society Consensus for the Management of Peripheral Arterial Disease) Type B-D (stenosis >10cm, occlusions >5cm; maximum length ≤30cm).

Condition or disease Intervention/treatment Phase
Peripheral Arterial Disease Device: Stent-avoiding Device: Stent-based Not Applicable

Detailed Description:

Prospective, multi-center 1:1 randomized Study.

Patients will be stratified according to a stent-avoiding (study arm) or stent-preferred (control arm)

In total 120 patient will be enrolled in this study, each strata will include 60 patients.

All enrolled patients will be followed up for 24 month to asses the incidence of restenosis by duplex ultrasound and major adverse events.

Follow-up visits occur at 6, 12 and 24 month intervals as well as telephone visit after 1 month.

Arm Intervention/treatment
Stent-avoiding approach
using clinically proven drug coated balloons
Device: Stent-avoiding
Percutaneous transluminal angioplasty (PTA), in which a balloon is advanced and inflated in the obstructed artery for several seconds to minutes, has become the standard endovascular treatment for peripheral arteries

Stent-based approach
using drug eluting nitinol stents. Interwoven nitinol stents in heavily calcified lesions at the operator's discretion.
Device: Stent-based
Stenting, in which a stent is advanced and implanted in the obstructed artery, has become the standard endovascular treatment for peripheral arteries

Primary Outcome Measures :
  1. Primary patency - Absence of clinically-driven target lesion revascularization (CD-TLR) and/or restenosis defined as a peak systolic velocity ratio (PSVR) > 2.4 assessed by ultrasound [ Time Frame: 1 Year ]

Secondary Outcome Measures :
  1. Walking capacity - Walking capacity assessed by Walking impairment questionnaire score at 6, 12 and 24 [ Time Frame: 2 Year ]
    The graded score is multiplied by a pre-specified weight for each distance, speed, or number of stair flights. The products are summed and divided by the maximum possible score to obtain a percent score, ranging from 0 (representing the inability to perform any of the tasks) to 100 (representing no difficult with any of the tasks)

  2. Ankle-brachial index - Clinical improvment assessed by Ankle-brachial index at 6, 12 and 24 month [ Time Frame: 2 Year ]
    The ABI is calculated by dividing the systolic blood pressure at the ankle by the systolic blood pressure in the arm. An ABI between and including 0.9 and 1.2 considered normal (free from significant PAD), while a lesser than 0.9 indicates arterial disease

  3. Rutherford category - Clinical improvment assessed by Rutherford category at 6, 12 and 24 month [ Time Frame: 2 Year ]

    This classification system consists of four grades and seven categories (categories 0-6):

    Grade 0, Category 0: asymptomatic Grade I, Category 1: mild claudication Grade I, Category 2: moderate claudication Grade I, Category 3: severe claudication Grade II, Category 4: rest pain Grade III, Category 5: minor tissue loss; ischemic ulceration not exceeding ulcer of the digits of the foot Grade IV, Category 6: major tissue loss; severe ischemic ulcers or frank gangrene

  4. Freedom from device and procedure-related death, all-cause death, target limb major amputation and clinically-driven target lesion revascularization [ Time Frame: 2 Years ]

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Subject age ≥ 18
  2. Subject has been informed of the nature of the study, agrees to participate, and has signed a Medical Ethics Committee approved consent form Subject understands the duration of the study, agrees to attend follow-up visits, and agrees to complete the required testing.
  3. Subject has a de novo or restenotic lesion with ≥ 70% stenosis documented angiographically and no prior stent in the target lesion.
  4. Rutherford Becker Classification 2-4
  5. Both treatment options seem feasible at the operator's discretion
  6. Femoropopliteal lesions classified as TASC II Type B-D with a maximum lesion length ≤ 30cm not involving the infrageniculate popliteal artery are eligible.
  7. Multiple lesions with max. 3cm healthy vessel segment in between lesions can be considered at the discretion of the operator as one lesion. Total lesion length should not exceed 30 cm.
  8. Reference vessel diameter (RVD) ≥ 4 mm and ≤ 6.5 mm by visual estimation.
  9. Patency of at least one (1) infrapopliteal artery to the ankle (< 50% diameter stenosis) in continuity with the native femoropopliteal artery. The inflow artery(ies) cannot be treated using a drug eluting stent or drug coated balloon
  10. A guidewire has successfully traversed the target treatment segment.

Exclusion Criteria:

  1. Failure to successfully cross the target lesion
