N2 - BACKGROUND: Endovascular intervention of femoropopliteal chronic total occlusions (CTOs) is technically more complex. However, there is lack of comparative analysis between CTO and non-CTO femoropopliteal interventions. METHODS AND RESULTS: We report procedural details and outcomes of patients treated for femoropopliteal CTO and non-CTO lesions in the XLPAD (Excellence in Peripheral Artery Disease) registry (NCT01904851) between 2006 and 2019. Primary outcomes were procedural success and 1-year major adverse limb events, a composite of all-cause death, target limb revascularization, or major amputation. Analysis included 2895 patients (CTO: n=1516 patients; non-CTO: n=1379 patients) with 3658 lesions (CTO: n=1998 lesions; non-CTO: n=1660 lesions). Conventional balloon angioplasty (20.86% versus 33.48%, P<0.001) or drug-coated balloon angioplasty (1.26% versus 2.93%, P<0.001) were more frequent in the non-CTO group, whereas baremetal stents (28.09% versus 20.22%, P<0.001) or covered stents (4.08% versus 1.83%, P<0.001) were more frequent in the CTO group. Debulking procedures were more commonly performed in the non-CTO group (41.44% versus 53.13%, P<0.001), despite a similar degree of calcification between the 2 groups. Procedural success was higher in the non-CTO group (90.12% versus 96.79%, P<0.001). Procedural complications were higher in the CTO group (7.21% versus 4.66%, P=0.002), mainly due to excess distal embolization (1.5% versus 0.6%, P=0.015). Adjusted 1-year major adverse limb events were higher in the CTO group (22.47% versus 18.77%, P=0.019), driven mainly by target limb revascularization (19.00% versus 15.34%, P=0.013). CONCLUSIONS: Procedural success is lower for endovascular treatment of femoropopliteal CTO compared with non-CTO lesions. CTO lesions are associated with higher rates of periprocedural complications and reinterventions after 1 year.
