Background: The aim of this study was to compare the 2-year outcomes of de novo versus postendovascular lesion treatment of femoropopliteal occlusions included in a national, multicenter, observational, prospective registry based on the treatment of critical Limb-threatening IschaeMia with infragenicular Bypass adopting in situ SAphenous VEin technique (LIMBSAVE) registry.Methods: From January 2018 to December 2019, 541 patients from43 centers have been enrolled in the LIMBSAVE registry. Of these patients, 460 were included in the present study: 341 (74.1%) with de novo lesions (DN group) and 119 (25.9%) with postendovascular treatment lesions (PE group). Initial outcome measures were assessed at 30 days after treatment. Furthermore, at the 2-year follow-up, the estimated outcomes of primary patency, primary-assisted patency, secondary patency, and limb salvage were analyzed with Kaplan-Meier curves and compared between groups with the log-rank test.Results: Both groups were homogeneous in terms of demographic data, preoperative risk factors, and clinical presentation. However, compared with DN group, more patients in PE group had a great saphenous vein diameter of less than 3 mm (11.1% vs 21%; P = .007). Intraoperatively, both groups showed similar distal anastomosis sites: below-the-knee popliteal artery (63% DN group, 66.4% PE group) and tibial vessel (37% DN group, 33.6% PE group) (P = .3). The overall mean duration of follow-up was 11.6 months (range, 1-24 months). At the 2-year follow-up, there were no differences between the two groups in terms of primary patency (66.3% DN group vs 74.1% PE group; P = .9), primary-assisted patency (78.2% DN group vs 79.5% PE group; P = .2), secondary patency (85.1% DN group vs 91.4% PE group; P = .2), and limb salvage (95.2% DN group vs 95.1% PE group; P = .9).Conclusions: The LIMBSAVE registry did not show a worsening of overall patency and limb salvages rates at the 2-year follow-up in patients undergoing in situ saphenous bypass after a failed endovascular approach for long femoropopliteal occlusive disease. This finding is in contrast with what has been published in literature.
