- Abstract
Although paclitaxel-based devices which demonstrated improved outcomes in the treatment of lower-extremity peripheral artery disease (PAD) have been used worldwide, Katsanos et al. reported a systematic review and summary-level meta-analysis of RCTs in which application of paclitaxel-based devices in the femoropopliteal artery was associated with an increased mortality risk. The purpose of this study was to describe the safety of endovascular therapy (EVT) using paclitaxel-coated stents for femoropopliteal disease by evaluating the mortality risk compared with patients treated with paclitaxel-free devices. A retrospective, multicenter, non-randomized study examined 481 de-novo symptomatic PAD patients treated in 13 Japanese medical centers from January 2011 to December 2015. The risk of all-cause mortality was analyzed between the 65 patients treated with a paclitaxel-coated stent (PTX-coated group) and 416 patients treated with an uncoated balloon or bare nitinol stent (PTX-free group). Overall survival of the PTX-coated group and the PTX-free group were compared after propensity score matching. The 2-year overall survival estimates were 87.7% in the PTX-coated group vs 88.7% in the PTX-free group. There were no significant differences in the mortality risk between the groups through a full follow-up of 2 years (p = 0.80). The multivariate cox proportional hazards model identified three significant predictors of mortality; age (HR, 1.08; 95% CI, 1.03-1.13; p = 0.002), hemodialysis (HR, 3.16; 95% CI, 1.34-7.42; p = 0.008), and albumin (g/dl) (HR, 0.46; 95% CI, 0.25-0.85; p = 0.01)., (© 2021.
