Classic aortic dissection is the most common aortic syndrome. The common denominator of acute aortic syndromes is the disruption of the middle layer, the presence of hemorrhage within the aortic wall (intramural hematoma), longitudinal extensive and progressive separation of the layers (aortic dissection) and disruption of the wall due to ulceration of an atheromatous plaque (penetrating atheromatous ulcer). The risk factors most frequently associated with aortic dissection are hypertension (72%), atherosclerosis (31%) and a history of previous cardiac surgery. The classification of acute aortic dissection depends on the anatomical site of the intimal damage and the affected aortic segment. The two most widely used classifications are the DeBakey and Stanford systems. The most common symptom is chest pain. The combination of clinical signs, non-imaginological tools (electrocardiogram, biomarkers and chest radiography), and diagnostic techniques such as echocardiography, computed tomography, aortography and MRI have been used in different algorithms. Acute aortic syndromes that involve the ascending aorta are surgical emergencies. Conclusions: aortic dissection remains a catastrophic vascular disease, despite surgical management techniques and the advent of new endovascular interventions. Clinical suspicion and consultation with a cardiovascular surgeon are cornerstones in the early therapeutic approach for patients affected by acute aortic syndromes.
