[Thoracic Endovascular Aortic Repair for a Descending Thoracic Aneurysm Associated with Pseudocoarctation of the Aorta;Report of a Case].

A 77-year-old man with a descending thoracic aneurysm associated with pseudocoarctation of the aorta underwent thoracic endovascular aortic repair (TEVAR). Computed tomography demonstrated kinking of the descending thoracic aorta. The aneurysm was located distal to a kinking and constricting aortic isthmus. TEVAR was performed because of the patient's comorbidity such as valvular heart diseases and postradiation status for the thoracic Hodgkin disease. TEVAR was successful but small aortic dissection was occurred distal to the stentgraft. Computed tomography at 1 year after TEVAR demonstrated reduction of the aneurysmal diameter and no change in the small dissection. TEVAR is becoming the treatment of first choice for this disease.
