CEREBRAL OXIMETRY AS AN EFFECTIVE METHOD OF MONITORING THE ADEQUACY OF AN INSULATING CEREBRAL PERFUSION DURING OPERATIONS ON THE AORTIC ARCH

Abstract

Since January, 2012, till March, 2013, 29 combined ascending aortic and arch procedures were performed in the Centre. In all cases we used continuous intraoperative cerebral oximetry. In most part of cases aortic arch procedures were performed with circulatory arrest, moderate hypothermia and antegrade cerebral perfusion. Hospital mortality was 3 % (1 patient). In 2 cases post-operative course complicated with stroke. We revealed correlation between cerebral saturation measured during circulatory arrest and neurological adverse events in post-operative period. This method of monitoring of cerebral protection efficacy is effective and safe. Further investigations to assess cognitive function in the late post-operative period are needed.
