[X-ray and computed tomographic diagnosis of aneurysm of the thoracic aorta]

The paper is concerned with the results of x-ray and CT investigations conducted in 62 patients with suspected aneurysm of the thoracic aorta. The diagnosis was confirmed in 56. Of them 38 patients were operated on, 2 died without surgical intervention. X-ray investigations permitted differential diagnosis of mediastinal formations in 91.5% of cases. However in 2 cases when the combined method of intravenous administration of a contrast medium by means of a syringe was not used, aneurysmal aortic dilatation was not detected by CT. This method was found to be effective for diagnosis of complications of aneurysms of the thoracic aorta (calcinosis, aortic wall stratification and thrombosis of aneurysmal cavity).
