Brief Summary:
  • Prospective, multi-center, single-arm registry study
  • A total of 100 subjects with isolated popliteal artery lesions according to inclusion and exclusion criteria will be enrolled.
  • All popliteal artery lesions will be treated with drug-eluting balloon (In.PACT Admiral, Medtronic). • Atherectomy or use of bare nitinol stent in combination with drug-eluting balloon is allowed • Patients will be followed clinically for 12 months after the procedure.
  • Imaging study (Duplex ultrasound, CT angiography or catheter angiography) follow-up will be performed at 12 months.

Condition or disease Intervention/treatment
Popliteal Artery Disease Device: drug-eluting balloon (In.PACT Admiral, Medtronic)

Study Type : Observational
Estimated Enrollment : 100 participants
Observational Model: Case-Only
Time Perspective: Prospective
Study Start Date : January 2016
Estimated Primary Completion Date : March 2021
Estimated Study Completion Date : March 2021

Group/Cohort Intervention/treatment
Patients with isolated popliteal artery disease undergoing endovascular therapy using drug-eluting balloon (In.PACT Admiral, Medtronic)
Device: drug-eluting balloon (In.PACT Admiral, Medtronic)

Primary Outcome Measures :
  1. Primary patency rate [ Time Frame: 12 months after the index procedure ]
    absence of restenosis >50% based on an imaging study (Duplex ultrasound, CT angiography or catheter angiography) at 12 months

Secondary Outcome Measures :
  1. Target vessel revascularization rate [ Time Frame: 12 months ]
    frequency of repeat intervention or surgical treatment due to loss of patency at the target vessel
