CHOCO-CABANA Trial

The study will be performed 120 patients at about 6 to 8 study centers. Only patients with clinical conditions requiring assessment of patency of the treated BTK lesions at 6 months post procedure by MRA as part of standard care to prevent amputations as consequence of non-detected re-stenosis/occlusions will be included in the study. The sequence in which the individual patients will be treated will be randomized with the Chocolate PTA balloon and the uncoated conventional PTA balloon at each center. 60 patients will be randomized to uncoated conventional PTA balloon treatment and 60 patients to treatment with the Chocolate PTA balloon. All lesions in each patient (lesions that fulfill the inclusion/exclusion criteria) should be treated as the patient is randomized. In patients with long lesions more than one balloon may be used. Overlapping of balloons (at least 10mm) is mandatory to avoid untreated gaps between sequential treatments. Follow up will be performed at 1 and 6 months.
