title: [A successful surgical treatment of chronic traumatic mid-descending thoracic aortic aneurysm].
abstract: A 48-year-old woman with chronic mid-descending thoracic aortic aneurysm was successfully repaired. She received a blunt chest trauma due to automobile accident at July in 1988. Left upper lobectomy was performed for her lung contusion. March 1990, she admitted our hospital with abnormal shadow revealed by a chest roentgenogram. A computed tomogram of the chest and an aortogram revealed two false aneurysms. One of them was located at mid-descending thoracic aorta and another was aortic isthmus. Under a partial femoral veno-arterial bypass, a Dacron graft replacement of mid-descending thoracic aorta was performed and aneurysm of isthmus was wrapped by Teflon mesh after the left pneumonectomy. 2 months after the operation, bronchopulmonary fistula occurred at the left bronchial stump. The fistula was successfully covered with major omentum. The mid-descending thoracic aortic aneurysm due to blunt chest trauma is rare. The traumatic aortic aneurysms commonly occur aortic isthmus or ascending aorta. Initial diagnosis of traumatic mid-descending thoracic aortic aneurysm is often missed or delayed. Careful follow up is need and when an abnormality is revealed by chest roentgenogram, computed tomogram and aortogram should be obtained to make diagnosis of chronic traumatic aneurysm.
