Abstract
To assess the technical success of GoBack™ crossing catheter in chronic total occlusion. A retrospective review of chronic limb threatening ischemia (CLTI) patients treated for chronic total occlusions (CTO) with the application of the GoBack™ crossing catheter (Upstream Peripheral Technologies, Haifa, Israel) between May 2020 and January 2021 was performed. Sixteen GoBack catheters were applied in twelve limbs in 12 patients (ten men, average age 75.7years). Treated limbs were classified as Rutherford Category 5 and 6 in ten patients and four in two patients. Average occlusion length was 287mm (62-466). All occluded arteries were heavily calcified. Technical success was defined as successful application of the GoBack catheter for lesion crossing or luminal reentry. Successful application of the four French catheter was achieved in 11 of the 12 cases (92%) for reentry in external iliac (1), superficial femoral (2), popliteal (2) and posterior tibial (1) arteries in six out of six cases (100%) and lesion crossing in popliteal (4), peroneal (1) and posterior tibial arteries in five out of six cases (83%). The 2.9 Fr catheter was successfully applied once out of four (25%) in lesion crossing in the posterior tibial artery. The GoBack™ 4 Fr crossing catheter in revascularization of CLI patients with CTO could be valuable when manual crossing or reentry is unsuccessful and is applicable from any access site.
