Efficacity Study With the Protégé EverFlex Stent in Popliteal Lesions (DUR-POP)
30 september 2013 uppdaterad av: Flanders Medical Research Program
DURABILITY-POP Study - Physician Initiated Trial Investigating the Efficacy of the Implant of Protégé EverFlex Nitinol Stents in Popliteal Lesions
This study will assess the results up to 12 months with the Protégé EverFlex stent (ev3) in patients presenting with a narrowing or blocking at the level of the knee artery, which leads to a limited walking distance, rest pain or non-healing ulcers.

Beskrivning
Inclusion Criteria:
General Inclusion criteria
- De novo, restenotic or reoccluded lesion located in the popliteal artery, with or without superficial femoral artery involvement
- Patient presenting a score from 2 to 5 following Rutherford classification
- Patient is willing to comply with specified follow-up evaluations at the specified times
- Patient is >18 years old
- Patient (or their legal representative) understands the nature of the procedure and provides written informed consent, prior to enrolment in the study
- Prior to enrollment, the guidewire has crossed target lesion
- Patient is eligible for treatment with the self-expanding nitinol EverFlex (ev3) stent
Angiographic Inclusion Criteria
- The target lesion has angiographic evidence of stenosis or restenosis > 50% or occlusion which can be passed with standard guidewire manipulation
- The target lesion, visually estimated, has a maximal length of 14 cm and can be categorized as either a type A or B lesions according the TASC II guidelines
- Target vessel diameter visually estimated is >3.5mm and <7.5 mm
- There is angiographic evidence of at least one-vessel-runoff to the foot
Exclusion Criteria:
- Presence of another stent in the target vessel that was placed during a previous procedure
- Presence of an aortic thrombosis or significant common femoral ipsilateral stenosis
- Previous by-pass surgery in the same limb
- Patients for whom antiplatelet therapy, anticoagulants or thrombolytic drugs are contraindicated
- Patients who exhibit persistent acute intraluminal thrombus of the proposed lesion site
- Perforation at the angioplasty site evidenced by extravasation of contrast medium
- Patients with known hypersensitivity to nickel-titanium
- Patients with uncorrected bleeding disorders
- Aneurysm located at the level of the SFA and/or popliteal artery
- Female patient with child bearing potential not taking adequate contraceptives or currently breastfeeding
- Life expectancy of less than twelve months
- Ipsilateral iliac treatment before the target lesion procedure with a residual stenosis > 30% or ipsilateral iliac treatment conducted after the target lesion procedure
- Use of thrombectomy, artherectomy or laser devices during procedure
- Any patient considered to be hemodynamically unstable at onset of procedure
- Patient is currently participating in another investigational drug or device study that has not completed the entire follow up period.

|
primary patency
Tidsram: 12 months post-procedure

Åtgärdsbeskrivning |
Tidsram |
|---|---|---|
|
Technical success
Tidsram: 1 day post-procedure
|
Technical success, defined as the ability to cross and dilate the lesion to achieve residual angiographic stenosis no greater than 30% and residual stenosis less than 50% by duplex imaging
|
1 day post-procedure
|
|
Primary patency rate at 6-, 12-month follow-up.
Tidsram: 6-, 12-month follow-up
|
Patients that present without a hemodynamically significant stenosis at the target area on duplex ultrasound (systolic velocity ratio no greater than 2.4) and without prior TLR are defined as being primary patent.
|
6-, 12-month follow-up
|
|
Clinical success
Tidsram: 6-, 12-month follow-up
|
Clinical success at follow-up is defined as an improvement of Rutherford classification at 6-, 12-month follow-up of one class or more as compared to the pre-procedure Rutherford classification.
|
6-, 12-month follow-up
|
|
tent fracture rate at 12-month follow-up
Tidsram: 12-month follow-up
|
Determined according the following classification on x-ray: Class 0 (no strut factures); Class I (single tine fracture); Class II (multiple tine factures); Class III (Stent fracture(s) with preserved alignment of the components); Class IV (Stent fracture(s) with mal-alignment of the components); Class V (Stent fracture(s) in a trans-axial spiral configuration)
|

|
|
Serious adverse events
Tidsram: 1 year
|
Defined as any clinical event that is fatal, life-threatening, or judged to be severe by the investigator; resulted in persistent or significant disability; necessitated surgical or percutaneous intervention; or required prolonged hospitalization.
