【摘要】 目的:总结急性主动脉综合征(acute aortic syndrome,AAS)影像诊断经验,明确多排螺旋CT(MDCT)的诊断价值。方法:对临床疑诊AAS的100例病例,行MDCT平扫及MDCT血管成像(MDCTA)后,运用GE ADW4.5分析软件进行图像处理后分析影像征象。结果:MDCT准确诊断42例AAS,其中主动脉夹层(acutic dissection,AD)18例,MDCT显示内膜破口、内膜片、真假腔;主动脉壁内血肿(intramural acutic hematoma,IMH)11例,MDCT显示主动脉壁增厚呈新月形、环形无强化高密度影,宽度≥5 mm;主动脉穿通溃疡(penetrating atherosclerotic acutic ulcers,PAU)13例,MDCT显示增厚主动脉壁内有局灶型造影剂填充,形成龛影。结论:充分认识AAS影像征象,及早诊断对于临床治疗及预后有重要价值,利用MDCT检查有明显的诊断优势。更多还原

【Abstract】 Objective:To sum up the imaging diagnosis experiences of Acute Aortic Syndrome(AAS), confirm diagnostic value of MDCT.Method: 100 clinical suspectedcases with AAS were examined by MDCT plain scan and MDCT angiography(MDCTA),process images with GE ADW4.5 analysis software,the images and signs were analyzed.Result:42 cases were accurate diagnosis as AAS, of which 18 cases were aorta dissection(AD),MDCT dispayded intimal entry,inti-mal flap,true lumen and false lumen of the aorta;11 cases were intramural hematoma(IMH),MDCT dispayded the aorta wall thickenings as crescent and annular,and no reinforced high density shadow,width≥5 mm;13 cases were penetrating atherosclerotic aorta ulcers(PAU),MDCT dispayded the thickened aortawall were filled with focal type contrast medium,niche were formed.Conclusion:Recognize the images and signs of AAS adequately and early diagnosis have important value to clinical treatment and prognosis, and the diagnosis advantages of using MDCT are obvious.更多还原
