胸片在早期诊断急性胸主动脉夹层中的应用

目的 :评价胸片检查对早期诊断急性胸主动脉夹层的临床应用价值。方法 :对我院核磁共振检查确诊的急性胸主动脉夹层 37例患者 (AD组 )和同龄对照组、高龄对照组各 10 0例患者胸片主动脉影像进行回顾性分析比较。结果 :AD组 37例急性胸主动脉夹层患者有 31例胸片主动脉有异常增宽发现 ,阳性率 83.8% ;而同龄对照组、高龄对照组仅 3%、11%有主动脉增宽表现 ,AD组和两对照组相比有显著差异 (p <0 .0 1) ;胸片对于升主动脉的病变敏感性为 18.5 %。结论 :胸片对急性胸主动脉夹层早期诊断有提示价值 ,有助于降低首诊误诊率

Chest radiograph for the early diagnosis of acute thoracic aortic dissection

Objective: To assess the diagnostic accuracy of routine chest radiography for the acute thoracic aortic dissection (AD). Method:During a 6-year period, 37 patients underwent chest radiograph before thoracic aortic dissection was diagnosed with magnetic resonance imaging (AD group), we also examined chest radiographs of 100 non-AD patients each of the same-aged control group and the old-aged control group. Chest films were evaluated retrospectively for aortic contour. Result: Aortic enlargement was found in the chest radiographs of 31 patients in the AD group, the sensitivity is 83.8%, the same-aged control group and the old-aged control group only has a sensitivity of 3% and 11% each, there was a significant difference between AD group and two control groups(p<0.01); sensitivity was only 18.5% for pathology of the ascending aorta. Conclusion: Chest radiograph has important suggestive value for early diagnosing the acute thoracic aortic dissection; it may help avoid delaying diagnosis.
