Answer

Aneurysm of the aorta can occur in unrepaired coarctation of the aorta and has been described in patients with Turner syndrome and coarctation of the aorta. In addition, endocarditis can result in aortic arch aneurysm (mycotic aneurysm), usually distal to the site of obstruction.

Patch repair of coarctation of the aorta results in an increased incidence of aortic aneurysm (usually opposite the site of the patch), particularly if the shelf of coarcted tissue is excised. Patients with aortic aneurysm can be entirely asymptomatic. Hoarseness that results from stretching of the recurrent laryngeal nerve associated with aortic aneurysm has been described. Chest radiographs are unlikely to reveal the aortic aneurysm, but MRI is more useful in delineating the size and extent of aneurysms.
