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.

摘要

A型主动脉夹层患者主动脉造影出现假阴性是一种罕见且严重的诊断错误。我们报告了3例A型胸主动脉夹层患者，其主动脉造影结果为阴性，但CT或磁共振成像结果为阳性。本文讨论了可能导致这种差异的因素以及对这些患者评估的影响。
