Introduction:

chest pain is a common presentation in the emergency department environment. Although most cases of chest pain that present in the emergency department are eventually diagnosed as non-cardiovascular aetiology, it is important to exclude acute life-threatening conditions such as acute myocardial infarction, pulmonary embolism, visceral perforation and aortic dissection. This publication aims to show the importance of CT Angiography in the diagnosis of this disease and to review the updated bibliography.

Case presentation:

45-year-old male patient with onset of chest pain and arterial hypertension, on CT angiography.

Discussion:

a type B aortic dissection was performed according to Stanford and type III according to the DeBakey classification, the patient was stabilized, cared for by a cardiologist, and referred to a tertiary hospital. Aortic dissection is a disease to consider in young patients who complain of sudden chest pain, hypertension, mainly if the D-dimer is altered;

Conclusions:

aortic dissection is a disease with a high risk of mortality that must be treated early; the most important radiological study in the diagnosis is CT angiography, the most common clinical presentation is atypical chest pain.
