The study objective was to determine predictors, and adverse outcomes of postoperative type II neurologic complications. An 11-year cohort (N=12,706) study with 595 coronary artery bypass graft (CABG) patients with a neurologic complication, and 7793 patients without any neurologic complications was conducted. This study examined 26 potential risk factors and 13 outcome variables. Logistic regression analysis found that patients were more likely to experience a neurologic complication after CABG if they were older than 70 years of age [odds ratio (OR), 3.8; 95% confidence interval (CI), 3.1-4.5; P < 0.001], had a previous intervention within 10 days before surgery (OR, 3.4; 95% CI, 1.4-8.3; P = 0.008), or had a higher creatinine level (OR, 0.9; 95% CI, 0.95-0.99; P = 0.013). Additionally, there was a significant difference between CABG patients with and without neurologic complications on 12 outcome variables. Type II neurologic complications after CABG are common and associated with an increased risk of postoperative morbidity and mortality.
