Blunt thoracic aortic injuries are potentially lethal. Those who survive may form an organised haematoma in the periadventitial space resulting in a pseudoaneurysm, which may be identified incidentally decades later. While the role of thoracic endovascular aortic repair (TEVAR) in acute settings has been established, its role in chronic cases is yet to be defined. We report three cases that were diagnosed incidentally six, nine and 18 years after the injury. Two were managed by TEVAR while the third declined intervention and is on annual followup. Patients with asymptomatic and stable pseudoaneurysms of the descending thoracic aorta should be offered surveillance versus TEVAR because the risk of rupture is not negligible, whilst taking into account the patient’s level of physical activity. These three cases highlight the importance of early diagnosis of aortic injuries in blunt trauma and its grading.
