Ductus arteriosus aneurysm presenting as hoarseness: successful repair with an endovascular approach

Abstract

An aneurysm of the ductus arteriosus is a rare finding, particularly in the adult population. These saccular aneurysms arise at the site of an incompletely obliterated ductus arteriosus along the lesser curvature of the aortic arch. Left untreated, it is associated with a high risk of potentially life-threatening complications including rupture, infection and thromboembolism. As a result, surgical correction is recommended. Previously, options were limited to open repair but as endovascular experience grows, novel techniques afford safer and less invasive alternatives. In contrast, neonatal ductus arteriosus aneurysms may regress spontaneously and expectant treatment can be justified. We present the case of a 74-year-old woman who presented with hoarseness secondary to a ductus arteriosus aneurysm; a diagnosis consistent with Ortner's syndrome. The patient underwent an uncomplicated endovascular repair using the chimney-graft technique.
