Comparison of Sirolimus vs Paclitaxel Drug Eluting Balloon for Below-the-knee Angioplasty in Critical Limb Ischemia

The objective of this study is to compare the remote patency of paclitaxel versus sirolimus eluting balloons in patients with CLI undergoing tibial artery revascularization. Patients will be randomized 1:1 to Paclitaxel eluting balloon (Litos, ACOTEC ltd) or sirolimus eluting balloon (Magic touch, Concept Medical) after optimal balloon angioplasty. The primary endpoint of the study is the late luminal loss at 6 months angiography. Secondary endpoint are major amputation, clinically driven target lesion revascularization and vessel reocclusion (duplex) at 12 months.
