[Chronic traumatic aneurysm of the thoracic aorta; report of a case].

We report a rare case of chronic traumatic aneurysm of the thoracic aorta. A 23-year-old man flew down from the fifth floor of his apartment for an attempted suicide. He suffered right subdural hematoma, bilateral hemothorax, lung contusions, and many other traumas. He was paralyzed by the fracture and dislocation of the first lumbar vertebra. Posterior fixation of lumbar vertebra and the segmental resection of the jejum were performed on the first and third day, respectively. He recovered well; however, he complained his nocturnal dyspnea on the forty-fifth day. Detailed examinations showed that bilateral bronchi were compressed by the aneurysm of thoracic aorta. Elective operation was performed on the sixty third day. Psudoaneurysm, 5 cm in diameter, was disclosed in the aortic isthmus. Graft replacement was undergone with the cardiopulmonary bypass. His postoperative course was uneventful, and he was transferred for the rehabilitation of his paralysis on the eigty-eighth day.
