DAART vs PTA/SUPERA STENTING FOR POPLITEAL ARTERY LESIONS

Status Completed

Clinical Trial Summary

The purpose of this study was to compare the results of directional atherectomy with antirestenotic therapy (DAART technique) and angioplasty/Supera stenting for the treatment of popliteal atherectomy lesions.

Clinical Trial Description

Atherectomy offers a way to improve the chances to avoid stent placement, although it did not show superiority in terms of vessel patency or limb salvage compared with POBA. Nevertheless, atherectomy can modify the plaque morphology and the mechanical properties of the baseline disease, which allows better drug penetration and diffusion into the vessel wall. Moreover, the combination of directional atherectomy devices and drug coated balloons (directional atherectomy with antirestenotic therapy, DAART), theoretically might further improve the clinical outcomes of drug coated angioplasty. The "leave nothing behind" strategies have gained support among interventionalist. Many studies claim that atherectomy improves results when combined with adjunctive DCB. The Supera stent, when compared with other self-expanding nitinol stents, has proven to deforms less with knee flexion and exhibits less strain. It mimics the natura structure and movement of the anatomy and optimizes luminal gain maintaining a round open lumen in challenging anatomies, as the popliteal artery. Mechanical scaffolding is often required owing to elastic recoil and flow-limiting dissections in complex popliteal lesions. The purpose to this study was to retrospectively evaluate the efficacy of both techniques for endovascular treatment of atherosclerotic lesions of the popliteal artery. ;
