Circulatory arrest is the main method used in surgical interventions for prosthetics of the proximal aorta. However, recently, facts have been discovered that prove the benefits of avoiding circulatory arrest during planned and emergency surgical interventions. We present a clinical case of planned prosthetics of the ascending section and the aortic arch with a Intergard Woven 28 mm multibranch prosthesis without circulatory arrest in conditions of mild hypothermia. The patient was extubated 5 hours after the operation, and was discharged home in satisfactory condition on the 7th day. The rejection of circulatory arrest made it possible to reduce the duration of surgery, the duration of hospitalization and complications associated with hypoperfusion of organs and tissues that occur during cooling of patients.
