AbstractNine 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. The presence of mediastinal hematoma necessitated aortography in 48 patients. However, operative treatment was carried out without aortography in 3 patients who had specific signs of rupture on CT. CT proved to be a reliable indicator for the selection of the patients who need aortography. 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.
