16层螺旋CT多维成像技术诊断主动脉夹层动脉瘤的临床应用价值(1)
【摘要】 目的：分析16层螺旋CT多维成像技术对主动脉夹层动脉瘤(ADA)的临床诊断价值。方法：2011年1月-2016年11月，择取于本院就诊的55例ADA患者作为研究对象，所有患者均接受16层螺旋CT多维成像技术及数字减影血管造影(DSA)检查，对比两者的诊断价值，并观察16层螺旋CT多维成像技术的影像学特点。结果：在ADA诊断阳性率及分型诊断准确率方面，16层螺旋CT与DSA相似；两种检查方法主动脉破口数比较，差异无统计学意义(P>0.05)，而累及分支血管数、夹层血栓形成及动脉壁钙化指标比较，16层螺旋CT较DSA更具优势(P<0.05)。结论：16层螺旋CT多维成像技术可清晰显示ADA的征象，对于判定病情、为合理制定治疗方案提供依据，故为ADA的理想诊断方法之一。

【Abstract】 Objective：To analyze the clinical value of 16 slice spiral CT multi dimension imaging technology in diagnosis of aortic dissecting aneurysm(ADA).Method：From January 2011 to November 2016，55 cases of ADA were selected in our hospital as the research objects，all patients received 16 slice spiral CT multi dimension imaging technology and digital subtraction angiography(DSA) inspecting，compared the diagnostic value of two inspection methods，and observed the imaging features of 16 slice spiral CT multi dimension imaging technology.Result：The positive rate of ADA accurate rate of categorizing diagnosis of 16 slice spiral CT and DSA were fairly.The number of aortic rupture of two methods was not statistically significant (P>0.05)，but the number of branch vessels involved，the interlayer thrombosis and arterial wall calcification had statistically significant，and 16 slice spiral CT was superior to DSA (P<0.05).Conclusion：16 slice spiral CT multi dimension imaging technology can clearly show the signs of ADA，determine the condition and provide a reasonable basis for the development of treatment programs，it is one of the ideal diagnostic method for ADA.

主動脉夹层动脉瘤(ADA)又称主动脉夹层，是指由各种原因所致的主动脉内膜破裂，使血液进入主动脉壁内造成血管壁分层形成双腔，本病病情复杂、危险，平均发病率为(50～100)/10万人，近年来随着饮食习惯的改变及生活水平的提高，发病率呈逐年升高趋势[1-2]。由于ADA症状、体征变化多样，故极易误诊，导致患者因治疗不及时而死亡，文献[3]报道，ADA患者若未及时干预，约有80%患者可在发病后3个月内死亡，因此早期诊断与积极治疗对于改善ADA患者的预后具有重要的意义。以往，数字减影血管造影(DSA)被认为是ADA的诊断“金标准”，但由于其创伤性、操作复杂、价格昂贵及并发症多等缺点，使得患者的检查依从性较差[4]。目前，多层螺旋CT技术(MSCT)的成熟与发展，为ADA的临床诊断提供了新的方法，其成像范围广，扫描分辨率高且扫描时间短，可对ADA病变进行多平面及多角度显示，临床应用价值较高[5]。本文主要探究了16层螺旋CT多维成像技术对ADA的诊断价值，并与DSA及进行对照，现报道如下。, http://www.100md.com(李佩文 朱新进 庞力沛 温浩茂)
