Using a new selective antegrade cerebral perfusion technique for ascending aorta and aortic arch repair

Abstract

Dissecting aortic aneurysm is one of the most dangerous diseases of the aorta, often leading to severe complications or death. Currently, due to the increased level of diagnosis and the speed of care for patients with aortic diseases, there is now a need to improve approaches to the treatment of this condition. This paper presents the outcomes of a technique developed at our center, Shumakov National Medical Research Center of Transplantology and Artificial Organs, for selective antegrade cerebral perfusion (SACP) when performing prosthetic replacement of the aortic arch under circulatory arrest. Surgical treatment is performed on an emergency basis. During these surgeries, we focused on preventing neurological complications. Analysis of the efficacy and safety of our SACP technique shows that we obtained positive outcomes. In the analysis of 10 cases of aortic arch replacement, there was no evidence indicating the presence of any neurological complication. This technique allows for more adequate monitoring of perfusion during reconstructive interventions on the ascending aorta and aortic arch than the classical perfusion technique.
