目的:探讨多层螺旋CT(MSCT)在急性主动脉综合征(AAS)的临床应用价值。方法:采用西门子Sensa-tion 16层螺旋CT扫描机,对59例主诉急性胸背痛患者进行MSCT检查。结果:59例患者中主动脉夹层(AD)40例,主动脉壁内血肿(IMH)11例,穿透性粥样硬化性溃疡(PAU)8例。MSCT能够显示三种疾病的特征性征象:AD可见内膜片和双腔征;IMH主动脉壁呈新月形或环形增厚≥5 mm;PAU为凸出于主动脉管腔外的造影剂充盈的龛影。结论:MSCT是一种快速、无创的检查方法,能为AAS的诊断提供重要信息。
Objective: To investigate the clinical value of multi-slice spiral CT (MSCT) in the diagnosis of acute aortic syndrome (AAS). Methods: Sixty-nine patients with acute chest and back pain were examined by MSCT with Siemens Sensa-tion 16-slice spiral CT scanner. Results: There were 40 cases of aortic dissection (AD), 11 cases of aortic wall hematoma (IMH) and 8 cases of penetrating atherosclerotic ulcer (PAU) in 59 cases. MSCT can display the characteristic signs of three diseases: AD visible endometrial and double lumen; IMH aortic wall showed crescent or annular thickening ≥ 5 mm; PAU is protruding out of the aortic luminal contrast agent Ying Ying filling. Conclusion: MSCT is a rapid and noninvasive method that can provide important information for the diagnosis of AAS.
