摘要
目的:评价多层螺旋计算机断层摄影术(MSCT)在主动脉壁内血肿(AIH)诊断中的价值。方法:采用GE Lightspeed Plus或Lightspeed 16螺旋计算机断层摄影术(CT)进行增强前后扫描,共发现20例AIH,为AIH组。另随机选取20例单纯主动脉粥样硬化病例作为对照组,比较两组患者MSCT征象。结果:①20例患者主动脉壁均呈新月形或环形增厚,达5.0～12.3 mm,CT值:45.6～75.4 Hu。②14例患者主动脉钙化内移达3.0～10.3 mm。③20例患者合并粥样硬化穿透性溃疡和内膜渗漏分别为15处和7处。④AIH组的主动脉壁最大厚度及平扫CT密度值、主动脉最大直径和主动脉钙化内移距离与对照组比较差异具有统计学意义(P<0.05)。结论:MSCT是检出AIH的快速、无创检查方法,对临床的诊断、鉴别诊断和治疗方案的确定有重要的指导意义,且便于治疗后随访观察。
Objective ：To evaluate the diagnostic value of MSCT in aortic intramural hematoma （AIH）.
Methods ：Twenty patients with AIH were found by using the contrast-enhanced MSCT in this study （AIH group） ,6 of them were treated by subsequent surgery. 20 patients with single atberosclerosis were randomly used as the Control group.
Results：All patients （n = 20） presented continuous crescentic or circumferential areas along the wall of aorta with CT value of 45.6 -75.4 Hu and 5 - 12. 3 mm in aortic wall thickness. Displacement of intimal calcification were found in 14 cases, it showed 3 - 10. 3 mm in distance. Penetrating atherosclerotic ulcer （ 15 places） ,leakage in false lumen （7 places） were found re- spectively. There were significant differences in the maximum thickness of aortic wall, density of pre-eontrast, maximum diameter of aorta and disolacement of intimal calcification between AIH group and Control group （ P 〈 0. 05 ）.
Conclusion：MSCT was a fast and noninvasive imaging modality in the diagnosis, treatment and follow up of aortic intramural hematoma.
