The question whether a given mediastinal lesion is amenable to surgery is not always answerable by roentgenograms or by fluoroscopy. Often the only accurate means of distinguishing vascular from nonvascular lesions is provided by angiocardiography and thoracic aortography. The techniques here described were used in obtaining 188 angiocardiograms and 17 thoracic aortograms in 200 patients. The value of the information so obtained in planning surgical procedures, if any, is illustrated by 12 case histories.
