OBJECTIVE: Paclitaxel (PTX)-coated peripheral arterial devices have been shown to decrease femoropopliteal artery restenosis and the need for reintervention compared with non-PTX-coated devices. The data regarding PTX efficacy and safety come from randomized controlled trials that almost exclusively enrolled patients with claudication. The outcomes of PTX treatment in patients who present with chronic limb-threatening ischemia (CLTI) are unknown. This study compares long-term outcomes in patients with CLTI treated with and without PTX.
METHODS: We retrospectively reviewed 983 patients with CLTI treated with femoropopliteal artery angioplasty, atherectomy, stent, or combination between 2011 and 2019. Procedures were performed with additional proximal or distal tibial interventions as needed. Kaplan-Meier survival analysis and multivariable Cox-regression analysis compared overall survival (OS), amputation-free survival (AFS), freedom from major amputation (ff-MA), and freedom from target vessel revascularization (ff-TVR) between patients treated with and without PTX.
RESULTS: Demographics, comorbidities, and Rutherford class were similar between 574 PTX (58.5%) and 409 non-PTX (41.6%) patients except that non-PTX patients were more likely to be male (56.2% vs 49.7%), dialysis dependent (19.6% vs 14.3%), and have higher average creatinine (2.3 vs 1.8 mg/dL). Through 4-year follow-up, the PTX group demonstrated a significant increase in OS (56.2% vs 43.9%, P = .013), AFS (52.6% vs 36.1%, P < .0001), ff-MA (87.4% vs 78.7%, P = .0007), and ff-TVR (77.6% vs 70.6%, P = .012). Multivariable Cox-regression analysis demonstrated that PTX treatment was associated with improved OS, AFS, ff-MA, and ff-TVR.
CONCLUSIONS: In patients with CLTI, treatment with a PTX-coated device is associated with improved OS, AFS, ff-MA, and ff-TVR through 4-year follow-up. PTX-coated devices may be especially beneficial in patients who present with CLTI.
