Abstract:
False-negative aortography in a patient with a type A dissection is an unusual and serious diagnostic error. We report three cases of type A thoracic dissections with negative aortography but positive CT or magnetic resonance. The factors that might account for this discrepancy and the implications in the evaluation of these patients are discussed.
