ABSTRACT

Aortic dissection (DA) is the most frequent cause of aortic emergency and must be diagnosed and treated urgently. It is associated with a high morbidity and mortality rate. 20% of patients with AD do not reach the emergency services. Type A dissection has a mortality rate of 1% per hour, with a mortality of 50% in the first 48 hours, after the chest pain has begun, but increases to 75% in the second week and around 90% at 3 months.
The treatment of acute DA is surgical The most accepted technique at present when there is compromise of the aortic arch consists of the use of circulatory arrest with selective cerebral perfusion antegrade (PCSA) to achieve a safer cerebral protection.
Four cases operated with the use of PCSA are presented, the variables determined during the extracorporeal circulation are exposed, as well as the methods used for the management of these patients, as well as the immediate postoperative evolution, mediate and hospital discharge.
The four patients on discharge evolved satisfactorily, with recovery of brain functions and with a minimum of postsurgical complications.
