Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Drug eluting stent
Device: Drug-eluting peripheral arterial(G-stream) stent system Manufacturer:Alain Medical (Beijing) Co., Ltd.
Sirolimus drug-eluting self-expanding stent available from 20mm to 250mm in length, 3.5mm to 7.5mm in diameter of superficial femoral and proximal popliteal arteries (SFA/PPA) cases for inhibiting in-stent restenosis and improve long-term outcome.
Active Comparator: Drug coating balloon
Device: AcoArt-Orchid® Drug Eluting Balloon Catheter Manufacturer: Acotec Scientific Co., Ltd
A proprietary lipophilic coating technology that uses magnesium sterate as excipient, facilitates paclitaxel transfer to the vessel wall, enhances drug delivery, and brings minimal downstream effect. Available from 20mm to 300 mm in length, 3mm to 12 mm in diameter, fits every SFA cases, reduces radiation exposure time.
