摘　　要：目的探讨多层螺旋CT血管造影(MSCTA)对主-髂动脉狭窄性病变定量分析的方法及临床意义。资料与方法经MSCTA检查并诊断为主-髂动脉广泛性狭窄的35例,应用多平面重组(MPR)、容积再现(VR)、高级血管分析(AVA)等方法,对病变血管狭窄率、病变长度及主-髂动脉分叉角度进行测量。对不同方法测量值均数的差异用配对样本t检验评价。结果MPR组与AVA组测量狭窄率的差异无统计学意义,VR组与AVA组测量长度与分叉角度的差异也无统计学意义(P>0.05)。结论不同图像重组方法在血管病变定量分析上各有优势,其中AVA功能全面、应用简便、可重复性好,可作为定量测量的首选方法,对主-髂动脉狭窄性病变作定量分析,有助于临床选择手术方式。Objective To investigate the method and chnical value of MSCT angiography in quantitative analysis of aortoiliac artery stenosis Materials and Methods 35 cases with aortoiliac artery stenosis confirmed by MSCTA used VR, MPR, AVA to measure the length, stenosis ratio and bifurcate angle of aortoiliac artery. A paired t test was performed to analyze the difference. Results There was no significant difference for MRP and AVA in stenosis ratio （P 〉 0. 05 ）. There was no significant difference for VR and AVA in length and angle either. Conclusion Various image reformations have different advantages in quantitative analysis in aortoihac artery stenosis. AVA is the first choice which is a multifunctional, convenient and repeatable, and it can be helpful for vascular surgeon to choose the operation method.
