Objective
Percutaneous techniques for crossing femoropopliteal chronic total occlusions (CTOs) offer an alternative to bypass surgery in patients deemed to be at increased risk due to advanced age or comorbidities. Bypass surgery in patients deemed to be at increased risk due to advanced age or comorbidities. Recent reports document good success rates in catheters designed to reconstitute peripherally occluded arteries following failed guidewire passage. The Wildcat and cittycat catheter is a novel device with a rotating distal tip and deployable wedges fashioned for channeling a passage through arterial occlusions.
Methods
Between June 2015 and November 2015, patients with peripheral arterial disease due to a femoropopliteal CTO>1 cm and <35 cm were evaluated for study. During treatment, the physician initially attempted to cross the CTO using conventional guidewires per protocol; if the guidewire successfully crossed, the patient was considered a screen failure and the Wildcat was not deployed. At 30 days, patients were reevaluated. The primary efficacy end point was successful crossing of the Wildcat into the distal true lumen as confirmed by angiography. Primary safety end points included no in-hospital or 30-day major adverse events, no clinically significant perforation or embolization, and no grade C or greater dissection. Additional datacollected included lesion length, and location.
