title: Remnant of a non-patent ductus arteriosus mimicking traumatic thoracic aorta transection: a case report.
abstract: We present an interesting case of a 53-year-old man with a non-patent ductus arteriosus erroneously diagnosed as acute thoracic aorta transection after a car accident. The aortography revealed a "rupture" of the linear inner curve of the aorta in the isthmus area, as well as a protrusion of the aortic lumen in the corresponding area. During the followed thoracotomy an intact thoracic aorta and the remnant of a non-patent ligamentum arteriosum were found. It is the first reported case and we review all the possible entities which may give a false-positive image of traumatic aortic transection.
