主动脉夹层与其临床和多层螺旋CT表现的相关性研究_主动脉夹层CT

　　[摘要] 目的 探讨主动脉粥样硬化伴发主动脉夹层与其临床和多层螺旋CT表现的相关性，为临床提供参考。 方法 采用前瞻性研究的方法对我院2010年4月～2012年4月收治的20例主动脉粥样硬化伴发主动脉夹层（实验组）和20例主动脉粥样硬化患者（对照组）的影像学资料及实验室检查指标进行比较分析。 结果 实验组和对照组的一般资料按照性别、年龄、收缩压、舒张压进行比较，除年龄外，性别、收缩压和舒张压差异均有统计学意义（P < 0.05）。实验组和对照组实验室各指标进行比较，除载脂蛋白A1外，实验组的各项指标均高于对照组，差异有统计学意义（P < 0.05）。20例主动脉粥样硬化伴发主动脉夹层患者中，A型有13例，占65%，B型有7例，占35%，比较两型实验室指标，除载脂蛋白外，A型较B型实验室指标均较高，差异有统计学意义（P < 0.05）。 结论 主动脉粥样硬化伴发主动脉夹层患者以A型为主，多排螺旋CT联合实验室相关指标的检查，对综合评估主动脉夹层与主动脉粥样硬化有重要的临床意义。

　　[Abstract] Objective To explore correlation on aortic atheroma comorbid aortic dissection and it"s clinical and MDCT performance. It provides reference for clinical. Methods 20 cases of aortic atheroma comorbid aortic dissection (experimental group) and 20 patients with aortic atheroma patients (control group) imaging material and laboratory tests index were analyzed by the method of prospective study in our hospital from April 2010 to April 2012. Results The experimental group and control group general material according to gender, age, systolic blood pressure, diastolic pressure was compared, in addition to the age, gender and systolic blood pressure and diastolic blood pressure, the difference was statistically significant (P < 0.05). The experimental group and control group compared each laboratory, except apolipoprotein A1, the index of the experimental group were higher than in the experimental group, the difference was statistically significant (P < 0.05). 20 cases of aortic atheroma with hair in patients with aortic dissection, type A had 13 patients (65%), type B had 7 patients (35%), more two types of laboratory index, except apolipoprotein, type A laboratory indexes higher than type B, the difference was statistically significant (P < 0.05). Conclusion For the patients of aortic atheroma comorbid aortic dissection, type A occupied the main, multidetector-row CT joint laboratory examination of the relevant indicators, the comprehensive evaluation aortic dissection and aortic atheroma have important clinical significance.

　　主动脉夹层（aortic dissection，AD）指主动脉腔内的血液通过内膜破口进入主动脉壁层内导致血管壁的分层而形成假性动脉瘤，发病急，进展快，病死率高，是心血管危重急症疾病之一[1]。目前，国内外学者一致的观点是早期诊断和治疗是降低本病死亡率的关键所在[2]。本研究对我院收治的主动脉粥样硬化伴发主动脉夹层与其临床和多层螺旋CT表现的相关性进行探讨，为临床提供参考。
