Misago Iliac Study (MISAGO ILIAC)

Patients with peripheral arterial disease, Rutherford 2 to 5.

Inclusion Criteria:

• Patient presenting with a stenotic or occlusive lesion at the iliac arteries suitable for stenting (on indication for primary stenting, based on the discretion of the investigator)
• 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 for the duration of the study
• 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
• Patient is eligible for treatment with the Misago (Terumo)

• The target lesion is either a modified TASC-II class A or B lesion with one of the listed specifications:

  • Type A lesions

    • Unilateral or bilateral stenoses of the Common Iliac Artery
    • Unilateral or bilateral single short (≤3 cm) stenosis of the External Iliac Artery

  • Type B lesions

    • Unilateral Common Iliac Artery occlusion
    • Single or multiple stenosis totaling 3-10 cm involving the External Iliac Artery not extending into the Common Femoral Artery
    • Unilateral External Iliac Artery occlusion not involving the origins of Internal Iliac Artery or Common Iliac Artery
• The target lesion has angiographic evidence of stenosis or restenosis > 50% or occlusion which can be passed with standard guidewire manipulation
• There is angiographic evidence of a patent Common an Deep Femoral Artery

Exclusion Criteria:

• The target lesion is either a modified TASC-II class B lesion with aortic lesion involvement:

  • Short (≤3 cm) stenosis of infrarenal aorta
• The target lesion is either a modified TASC-II class C or D lesion with aortic lesion involvement:
• Presence of aneurysm at the level of the iliac arteries
• Previously implanted stent(s) at the same lesion site
• Reference segment diameter is not suitable for available stent design
• Untreatable lesion located at the distal outflow arteries
• Use of alternative therapy (e.g. atherectomy, cutting balloon, laser, radiation therapy) as part of the index procedure
• Patients refusing treatment
• 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 a history of prior life-threatening contrast medium reaction
• Patients with known hypersensitivity to nickel-titanium
• Patients with uncorrected bleeding disorders
• Female patient with child bearing potential not taking adequate contraceptives or currently breastfeeding
• Life expectancy of less than twelve months
• Any planned surgical intervention/procedure within 30 days of the study 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.
