During the 10-year period, the frequency of CEA declined, whereas CAS use slowly increased. After multivariate propensity score\u2013matched analysis, CAS was associated with an increased risk of death (odds ratio [OR], 1.69; 95% confidence interval [CI], 1.40\u20132.04), stroke (OR, 1.43; 95% CI, 1.23\u20131.66), and major adverse events including death, stroke, and myocardial infarction (OR, 1.25; 95% CI, 1.13\u20131.39). In asymptomatic patients, there was no significant difference in major adverse events (OR, 1.08; 95% CI, 0.92\u20131.20;\n              <jats:italic>P<\/jats:italic>\n              =0.16 [\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001 for interaction between procedure type and symptom status]) between CAS and CEA.
