Overview
- Prospective, multi-center, randomized, controlled comparison study
- A total of 300 subjects with complex femoropopliteal artery disease will be included according to inclusion and exclusion criteria. Complex lesions include long lesions (>150 mm), calcified lesions (PACSS grade 2-4) and in-stent lesions.
- Patients will be randomized in a 1:1 manner into atherectomy plus drug-coated balloon (DCB) or angiography-guided intervention group. • The randomization will be startified by the participating center and in-stent restenosis lesion. • For the DCB treatment, either IN.PACT (Medtronic) or Ranger (Boston Scientific) DCB will be used. • For the atherectomy, HawkOne (Medtronic), Jetstream (Boston scientific), or Rotarex (Straub Medical) will be used. • The primary endpoint is primary patency at 12 months based on Kaplan-Meier survival analysis. • Ankle-brachial index and Image study follow-up (Duplex US, CT angiography, or catheter angiography) will be performed at 1 year.
- Patients will be followed clinically for 2 years after the procedure.
