Nine cases of traumatic thoracic aortic rupture (TAR), operated on at St. Marianna University Hospital between July 1980 and December 1988, were reviewed in order to evaluate the role of contrast-enhanced CT in the early diagnosis of TAR. The absence of mediastinal hematoma on CT eliminated the need for aortography in 30 (38.5%) of the 78 patients suspected of having TAR on the basis of chest roentgenograms. ⋯ As a rule, emergency operations were performed in these patients. Simple aortic crossclamping was employed in 4 patients, and heparinless left heart bypass with the BioPump was performed for spinal cord protection in 2 recent patients without complication of embolization. Use of the BioPump as an adjunct in the repair of TAR appears to be promising.
