Résumé
Epiaortic ultrasonography (EAU) is a valid imaging method to detect atherosclerotic changes of the ascending aorta and to guide surgical strategies for the prevention of cerebral embolism in patients undergoing isolated coronary artery bypass grafting (CABG). However, its use is not widespread. The impact of EAU on the outcome after isolated CABG was investigated in patients from the European Multicenter Study on Coronary Artery Bypass Grafting (E-CABG) registry. A systematic review and meta-analysis of the literature was performed to substantiate the findings of this observational study. EAU was performed intraoperatively in 673 of 7241 patients (9.3%) from the E-CABG registry. In the overall series, the rates of stroke without and with aortic manipulation were 0.3% and 1.3%, respectively (P = .003). In 660 propensity score-matched pairs, EAU was associated with significantly lower risk of stroke (0.6% vs 2.6%, P = .007). A literature search yielded 5 studies fulfilling the inclusion criteria. These studies, along with the present one, included 11,496 patients, of whom 3026 (25.7%) underwent intraoperative EAU. Their rate of postoperative stroke was significantly lower than in patients not investigated with EAU (pooled rate, 0.6% vs 1.9%; risk ratio, 0.40; 95% confidence interval, 0.24-0.66; I Avoiding aortic manipulation is associated with the lowest risk of stroke in patients undergoing CABG. When manipulation of the ascending aorta is planned, EAU is effective in guiding the surgical strategy to reduce the risk for embolic stroke in these patients.

BACKGROUND
Epiaortic ultrasonography (EAU) is a valid imaging method to detect atherosclerotic changes of the ascending aorta and to guide surgical strategies for the prevention of cerebral embolism in patients undergoing isolated coronary artery bypass grafting (CABG). However, its use is not widespread.
METHODS
The impact of EAU on the outcome after isolated CABG was investigated in patients from the European Multicenter Study on Coronary Artery Bypass Grafting (E-CABG) registry. A systematic review and meta-analysis of the literature was performed to substantiate the findings of this observational study.
RESULTS
EAU was performed intraoperatively in 673 of 7241 patients (9.3%) from the E-CABG registry. In the overall series, the rates of stroke without and with aortic manipulation were 0.3% and 1.3%, respectively (P = .003). In 660 propensity score-matched pairs, EAU was associated with significantly lower risk of stroke (0.6% vs 2.6%, P = .007). A literature search yielded 5 studies fulfilling the inclusion criteria. These studies, along with the present one, included 11,496 patients, of whom 3026 (25.7%) underwent intraoperative EAU. Their rate of postoperative stroke was significantly lower than in patients not investigated with EAU (pooled rate, 0.6% vs 1.9%; risk ratio, 0.40; 95% confidence interval, 0.24-0.66; I
CONCLUSIONS
Avoiding aortic manipulation is associated with the lowest risk of stroke in patients undergoing CABG. When manipulation of the ascending aorta is planned, EAU is effective in guiding the surgical strategy to reduce the risk for embolic stroke in these patients.
