A study of peripheral vascular interventions in patients with peripheral artery disease (PAD) has demonstrated “high freedom” from major amputation at three years, according to study sponsor Cardiovascular Systems.
The Liberty 360° study enrolled more than 1,200 patients at 51 sites across the U.S. It followed patients across the spectrum of symptomatic PAD, and included 100 patients with the most severe form of critical limb ischemia (CLI). Although most patients were treated with St. Paul, Minn.-based Cardiovascular Systems’ orbital atherectomy system (OAS), the study was open to patients treated with any FDA-cleared endovascular device for the treatment of PAD.
