Background The aim of this study was to determine perioperative factors influencing neurologic outcome in a single-center cohort of patients undergoing elective aortic arch operations. Methods From January 2005 to June 2015, 791 consecutive patients received open aortic arch operations with either antegrade selective cerebral perfusion (ASCP) (636 patients [80.4%]) or deep hypothermic circulatory arrest (DHCA) (155 patients [19.6%]). Main indications were degenerative aneurysm (85%) and chronic postdissection aneurysm (9.1%). Results Hospital mortality (30 days) was 5.3%. Permanent neurologic dysfunction (PND) was observed in 42 patients (5.3%). Significant risk factors for PND appeared to be femoral artery cannulation (p = 0.003), progressive cardiopulmonary bypass (p = 0.001), circulatory arrest (p = 0.001), and ASCP time (p = 0.011). ASCP, in contrast to DHCA, was protective against PND (odds ratio [OR], 0.37; p = 0.003). Temporary neurologic dysfunction (TND) was observed in 49 patients (6.2%). Preoperative transient ischemic attack (TIA) (p = 0.001), progressive EuroSCORE (p = 0.001), left ventricular ejection fraction (LVEF) less than 50% (p = 0.003), and the use of femoral artery cannulation (p = 0.049) showed correlation in the univariate analysis. Stepwise logistic regression indicated TIA (p = 0.002; OR, 3.24) and the EuroSCORE (p = 0.003; OR, 1.23) as independent predictors of TND. Conclusions Contemporary elective aortic arch repair can be achieved with low mortality and a low incidence of neurologic dysfunction. ASCP was confirmed to be the safest method of cerebral protection. The extent of aortic arch replacement (apart from the frozen elephant trunk [FET] procedure) was not related to increased rates of TND or PND.

Abstract

Background The aim of this study was to determine perioperative factors influencing neurologic outcome in a single-center cohort of patients undergoing elective aortic arch operations. Methods From January 2005 to June 2015, 791 consecutive patients received open aortic arch operations with either antegrade selective cerebral perfusion (ASCP) (636 patients [80.4%]) or deep hypothermic circulatory arrest (DHCA) (155 patients [19.6%]). Main indications were degenerative aneurysm (85%) and chronic postdissection aneurysm (9.1%). Results Hospital mortality (30 days) was 5.3%. Permanent neurologic dysfunction (PND) was observed in 42 patients (5.3%). Significant risk factors for PND appeared to be femoral artery cannulation (p = 0.003), progressive cardiopulmonary bypass (p = 0.001), circulatory arrest (p = 0.001), and ASCP time (p = 0.011). ASCP, in contrast to DHCA, was protective against PND (odds ratio [OR], 0.37; p = 0.003). Temporary neurologic dysfunction (TND) was observed in 49 patients (6.2%).
