BACKGROUND: The outcome of endovascular intervention (EVI) compared vs. surgical revascularization in patients with peripheral artery disease (PAD) due to chronic total occlusion (CTO) is unknown. METHODS: Using the National Inpatient Sample database between 2007 and 2014, we identified all PAD patients with CTO who had limb revascularization. Multivariate analysis was performed to estimate the odds of in-hospital mortality and adverse outcomes between both groups. RESULTS: A total of 168,420 patients who had peripheral CTO and underwent limb revascularization were identified. 99,279 underwent EVI, and 69,141 underwent surgical revascularization. The patients who underwent EVI were younger, more likely to be women and African American, and less likely to be white (p < 0.001 for all). EVI was associated with lower in-hospital mortality (1.2% vs 1.7%, adjusted odds ratio [aOR]: 0.54; 95% confidence interval [CI] 0.50-0.59). The EVI group had higher vascular complications, major bleeding, acute kidney injury (AKI), and major amputation compared with surgical revascularization. A subgroup analysis on patients with critical limb ischemia showed lower mortality in the EVI group (1.4% vs. 1.9, aOR 0.56; 95% CI 0.50-0.63). Although there was no difference in the incidence of AKI or major amputation between the two groups, the EVI group had higher vascular complication rates and major bleeding events. CONCLUSION: EVI in PAD with CTO is associated with lower in-hospital mortality, likely due to the procedure's less-invasive nature; however, it is associated with higher postprocedural complications likely due to the CTO's complexity.
