FUTURE BTK: Randomized Controlled Trial of First SirolimUs CoaTed Balloon VersUs StandaRd Balloon Angioplasty in The TrEatment of Below The Knee Arterial Disease
This study aims to conduct a randomized, double blind, randomised controlled multicentre trial of sirolimus drug coated balloon versus standard percutaneous transluminal angioplasty for the treatment of below the knee arterial disease.
• Age ≥ 21 years or minimum age
• Rutherford class 4 to 6 in the target limb
• Intraoperative Inclusion Criteria
• Single or sequential de novo or re-stenotic lesions (stenosis of \> 50% or occlusions) from 2 to 20cm in the proximal 200mm of below the knee arteries. Lesion is considered as one lesion if there is maximum of 30mm gap between lesions at discretion of investigator. Below the knee arteries are tibioperoneal trunk, anterior tibial artery, posterior tibial artery and peroneal artery
• Inflow free from flow limiting lesions (\<50% stenosis) confirmed by duplex or angiography. Subjects with flow limiting inflow lesions (\>50% stenosis) can be included if lesion had been treated successfully (\<30% residual stenosis) before or during the index procedure.
• Target vessel has angiographically documented run off to the foot after treatment (ie. without significant stenosis)
