[Acute aortic syndrome].

Acute aortic syndrome is a group of pathogenic conditions including aortic dissection, intramural haematoma, penetrating ulcer and aortic aneurysm. The syndrome is a challenging clinical diagnosis because the symptoms are numerous and diverse with similarity to other more common conditions. Delayed diagnosis and treatment can be fatal. Computed tomography angiography is the most important diagnostic tool and is the first choice when acute aortic syndrome is suspected. With this article, we wish to raise awareness of the incidence of acute aortic syndrome and the clinical features of the syndrome.
