Objectives The purpose of this article was to study clinical presentations of aortic emergency and to review CTA features in aortic emergency. Methods This retrospectively studied patients presenting with clinically suspected aortic emer-gency in thoracic aorta and abdominal aorta, who underwent emergency CTA at Lamphun hos-pital between January 2012 and August 2015. Presenting symptoms and signs were compared with the results of CTA. CTA imaging findings of the lesions in thoracic aorta and abdominal aorta were reviewed. Results Of the 47 patients enrolled. There were 23 patients clinically suspected lesions in tho-racic aorta and 24 patients were clinically suspected lesion in abdominal aorta. Lesions of the aorta were aortic dissection in 6 pts, rupture thoracic aneurysm in 6 pts, rupture AAA in 10 pts and impending rupture AAA in 5 pts. Presenting symptoms and signs that were found in positive CTA group were also found in negative CTA group as well in both clinically suspected lesions in thoracic and abdominal aorta, which were not significant different. The most common acute aortic syndrome was aortic dissection. CTA imaging findings of rupture aortic aneurysm could be categorized into impending rupture aneurysm and rupture aneurysm. The most common sign of impending rupture aneurysm was IMH and the most common sign of rupture aneurysm was concomitant presence of an aortic aneurysm and an adjacent hematoma. Conclusions Clinical presentations in aortic emergency were nonspecific. Further imaging investigation was necessary and CTA had important role for definite diagnosis and treatment planning.
