Aim: The aim of the current study was to describe the clinical profile, frequency of in-hospital complications, and predictors of adverse events in patients undergoing endovascular therapy (EVT) for acute limb ischemia (ALI), and to compare them with those of patients undergoing EVT for chronic symptomatic peripheral artery disease (PAD). Methods: The current study compared 2,398 cases of EVT for ALI with 74,171 cases of EVT for chronic symptomatic PAD performed between January 2015 and December 2018 in Japan. We first compared the clinical profiles of ALI patients with those of PAD patients. We then evaluated the proportion of in-hospital complications and investigated their risk factors in the ALI patients. The association of clinical characteristics with the risk of in-hospital complications was analyzed via logistic regression modeling. Results: Patients with ALI were older and had a higher prevalence of female sex, impaired mobility, and history of cerebrovascular disease, but a lower prevalence of cardiovascular risk factors and history of coronary artery dis-ease. The proportion of in-hospital EVT-related complications in ALI was 6.1% and was significantly higher compared with those in chronic symptomatic PAD patients (2.0%, P<0.001). Bedridden status (adjusted odds ratio [aOR], 1.74 [1.14 to 2.66]; P=0.010), history of coronary artery disease (aOR, 1.80 [1.21 to 2.68]; P =0.004), and a suprapopliteal lesion (aOR, 1.70 [1.05 to 2.74]; P=0.030) were identified as independent risk factors for in-hospital complications. Conclusion: The current study demonstrated that ALI patients with significant comorbidities show a higher proportion of in-hospital complications after EVT.
