Screening for the vulnerable aorta: targeting high-risk groups in the population.

Thoracic aortic aneurysms are often asymptomatic until patients present with a life-threatening acute aortic syndrome. The vulnerability of an aorta to an acute aortic syndrome is determined by cross-sectional diameter and underlying aetiological factors, such as genotype or acquired disease. Screening the general population for thoracic aneurysms presents multiple resource issues including the availability of imaging modalities. Targeted screening of high-risk groups provides the only currently pragmatic solution. Opportunistic imaging through lung cancer screening programmes could pick up a proportion. Until we have a comprehensive screening programme it is incumbent on all healthcare professionals to have a low threshold for considering acute aortic pathologies when reviewing patients presenting with chest pain.
