• W1976507848 abstract "ObjectiveThis study was conducted to investigate the influence of coronary artery bypass grafting (CABG), carotid patching, and other factors on the outcome of all carotid endarterectomies (CEAs) performed by a single surgeon at a tertiary referral center.MethodsThe series includes 2262 CEAs (335 bilateral) in 1521 men and 741 women (33%) with median ages of 66 and 68 years, respectively. Surgical indications were asymptomatic stenosis for 1503 procedures (66%), retinal ischemia or cerebral transient ischemic attacks each for 271 (12%), and prior stroke for 217 (9.6%). CEA was done as an isolated operation in 1959 patients and was performed in conjunction with simultaneous CABG in 303 (13%). Primary arteriotomy closure was used for 783 CEAs (35%), vein patching for 1232 (54%), and synthetic patching for 247 (11%). Outcome event rates were assessed by logistic regression analysis, proportional hazards models, and Kaplan-Meier estimations.ResultsPostoperative mortality (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.7 to 7.5; P = .001), stroke (OR, 3.2; 95% CI, 1.6 to 6.4; P = .001), and combined stroke and mortality rates (OR, 3.4; 95% CI, 2.0 to 5.8; P < .001) were significantly higher for simultaneous CEA/CABG than for isolated CEA. Ipsilateral postoperative stroke rates were similar (2.6% vs 1.7%, P = .41) in both settings. Vein patching had a lower risk for ipsilateral stroke (OR, 0.42; 95% CI, 0.21 to 0.86; P = .015) than primary closure, but was not significantly different from synthetic patching (P = .10). The documented incidence of postoperative carotid thrombosis was 1.5% with primary closure, 0.6% with vein patching, and 2.0% with synthetic patching (P = .088). Overall Kaplan-Meier survival was 92% at 1 year, 71% at 5 years, 41% at 10 years, and 20% at 15 years, but long-term mortality rates were higher after simultaneous CEA/CABG (hazard ratio, 1.3; 95% CI, 1.1 to 1.5; P = .002) than after CEA alone. Late strokes or retinal infarctions have been reported after 97 (5.0%) of the 1923 operations for which follow-up was available, 51 (2.3%) of which were ipsilateral to CEA. The incidence of ≥60% recurrent stenosis was independently influenced by carotid patching (OR, 0.61; 95% CI, 0.40 to 0.92; P = .019) but not by the choice of patch material (P = .11).ConclusionsThese results substantiate the common observation that patients who require simultaneous CEA/CABG have a higher risk for adverse outcomes than patients who undergo isolated CEA. Carotid patching provided significant benefit with respect to the risks for ipsilateral postoperative stroke and ≥60% recurrent stenosis.
