【摘要】：目的:运用多层螺旋CT血管成像(MSCTA)评价主动脉壁内血肿(IMH)及其预后,并经Logistic回归分析IMH预后因素。方法:回顾分析33例初次行胸腹主动脉MSCTA诊断为IMH并进行保守治疗后再次MSCTA复查患者的临床及影像资料,评估IMH的预后,并将患者初次行MSCTA时的年龄、性别、是否合并有粥样硬化、Stanford分型、受累主动脉直径、血肿最大厚度是否≥11mm、是否合并穿透性动脉粥样硬化性溃疡(PAU)、血肿内是否有局限性强化影8项指标纳入Logistic回归分析,探讨IMH预后的危险因素。结果:33例IMH患者中20例(60.6%)有进展,经Logistic回归分析,得到的回归方程为:Logit(P)=-10.489+1.915X1-2.277X3+3.251X5+3.436X6+2.018X7,年龄、受累主动脉直径、血肿最大厚度≥11mm及合并PAU是IMH预后不良的危险因素,合并粥样硬化为保护因素。结论:根据危险因素和回归预测结果,可对IMH预后做出较准确的评价,并对IMH的治疗计划选择提供理论依据,延长患者生命。
[Abstract]:Objective: to evaluate aortic intramural hematoma (IMH) and its prognosis by multislice spiral CT angiography (MSCTA), and to analyze the prognostic factors of IMH by logistic regression analysis. Methods: the clinical and imaging data of 33 patients with IMH diagnosed as IMH by primary aortic MSCTA and conservative treatment were retrospectively analyzed. The prognosis of IMH was evaluated, and the age and sex of the patients at the first time of MSCTA were analyzed. Whether there were Stanford classification of atherosclerosis, diameter of involved aorta, maximum thickness of hematoma 鈮，
