Aortic arch elongation and bovine arch variants were recorded. Catheter manipulation time (CMT) was assessed for each patient. Adverse cardiovascular and cerebral events were assessed at 30 days.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 282 consecutive patients undergoing CAS under proximal balloon occlusion (57.8%) or distal filter (42.2%) neuroprotection were enrolled (age, 72\u2009\u00b1\u20097 years; 72.7% males). Type II and III elongation variants were detected in 23.4% and 10.6% of patients, respectively; in total, 20.5% of the patients had bovine configuration. CMT was significantly influenced by aortic elongation (56.1\u2009\u00b1\u200916.5 min in patients with type III aortic arch configuration compared to 38.2\u2009\u00b1\u200911.6 min in patients with type I or type II, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01) and (in left ICA) by bovine configuration (49.2\u2009\u00b1\u200911.4 min in bovine variants vs. 37.7\u2009\u00b1\u200911.5 min in patients with nonbovine anatomy, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). CMT, but not aortic arch anatomy, resulted the only independent predictor of 30\u2010day adverse outcome (hazard ratio [HR], 1.07; 95% confidence interval [CI], 1.03\u20131.10, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Adverse aortic arch anatomies are frequently encountered in CAS procedures and are associated to longer procedural times. A longer CMT increases the risk for adverse outcome. These data suggest that a careful procedure planning aimed at a reduction of CMT may be pivotal to improve the safety of CAS procedures. \u00a9 2015 Wiley Periodicals,
