64排螺旋CT在主动脉壁内血肿诊断中的应用

目的：探讨64排螺旋CT在诊断主动脉壁内血肿中的应用价值。方法：2007-01～2009-06间529例主动脉血管成像检查中诊断主动脉夹层160例,其中21例为壁内血肿,男16例,女5例。分析其影像特征及临床特点。结果：64排CTA所见征象：钙化内移4例,穿透性溃疡13例,主动脉粥样硬化13例,胸腔积液4例。病变中Standford A型9例,Standford B型12例,2例伴主动脉真性动脉瘤。结论：64排螺旋CT对主动脉壁内血肿是一种无创、安全、有效的诊断方法,可清晰显示IMH的直接、间接征象,对临床诊治有重要的指导意义。

APPLICATION OF 64-SLICE SPIRAL CT TO THE DIAGNOSIS OF AORTIC INTRAMURAL HEMATOMA

Objective：To study the value of 64-slice Spiral CT in the diagnosis of aortic intramural hematoma（IMH）.Methods：Between January 2007 and June 2009,160 patients with aortic dissection were scanned by 64-slice Spiral CT from 529 cases.21 patients（male 16,female 5）among them were aortic IMH.The clinical data and CT findings were analyzed.Results：The CT angiographic（CTA） features of aortic IMH were as follows ：displacement of intimal calcification（5 cases）,penetrating ulcer（13 cases）,atherosclerosis （13 cases） ,pleural effusion（4 cases）. Among the 21 cases, Stanford A type and Stanford B type were involved in 9 and respectively. The complication signs were true aneurysm （2 cases）. Conclusion：64 -slice Spiral CT is a noninvasive ,safe and fast method for the diagnosis of aortic IMH and can show the direct and indirect signs of aortic IMH. All these signs have important value for clinical diagnosis and treatment.
