Offroad re-entry catheter system for subintimal recanalization of chronic total occlusions in femoropopliteal arteries: primary safety and effectiveness results of the re-route trial

AIM: Aim of the study was to provide additional clinical data regarding the safety and technical success of the OffRoad Re-Entry Catheter System (Boston Scientific, Natick, MA, USA) for subintimal recanalization of chronic total occlusions (CTO) in the femoropopliteal arteries. - METHODS: A total of...

520 |a AIM: Aim of the study was to provide additional clinical data regarding the safety and technical success of the OffRoad Re-Entry Catheter System (Boston Scientific, Natick, MA, USA) for subintimal recanalization of chronic total occlusions (CTO) in the femoropopliteal arteries. - METHODS: A total of 92 patients (mean age 70.3±10.6 years; 70% male) were enrolled in this prospective, single-arm, post-market study conducted at 12 European centers. Patients were required to have claudication or critical limb ischemia and a CTO lesion in a native femoropopliteal artery. The primary safety endpoint was the composite rate of device-related major adverse events (MAEs; i.e., death, perforation requiring intervention, clinically significant peripheral embolism, and major amputation of the treated lower limb) at 30 days. Effectiveness was based on device technical success, defined as placement of a guidewire in the true lumen distal to a CTO. - RESULTS: Ninety patients were evaluable for the primary safety endpoint. The 30-day device-related MAE rate was 3.3% (3/90), with an upper confidence bound of 6.5%, which was lower than the prespecified performance goal of 15%. All 3 events were clinically significant peripheral emboli. Technical success was 84.8% (78/92) with a lower confidence bound of 78.6%, which exceeded the prespecified performance goal of 76%. A decrease of ≥1 Rutherford category was observed in 75% (65/87) of patients at the 30 day visit. - CONCLUSION: The Re-ROUTE trial results demonstrate acceptable performance of the OffRoad system in terms of safety and technical success for the recanalization of femoropopliteal CTOs.
