摘　　要：目的:探讨DSA仿真内窥镜(VE)技术在动脉瘤介入治疗中的应用价值。方法:回顾性分析21例脑动脉瘤患者的介入手术图像,使用GE ADW4.4工作站对原始数据进行容积再积(VR)和VE重建,确定工作体位,分别在VE和VR重建图像上测量动脉瘤瘤颈直径,并进行比较分析。结果:21例患者中有10例动脉瘤瘤颈在VR图像上显示不佳,在VE图像上清晰显示,两种方法测量的瘤颈直径分别为(3.13±1.09)mm和(2.56±1.34)mm,差异有统计学意义(P<0.05);11例动脉瘤瘤颈在VR和VE重建图像上均显示清晰,两种方法测量的瘤颈直径分别为(2.95±1.39)mm和(2.92±1.48)mm,差异无统计学意义(P>0.05)。所有21例病例中,两种方法测量的瘤颈直径分别为(3.04±1.23)mm和(2.75±1.39)mm,差异有统计学意义(P<0.05)。在VR图像动脉瘤瘤颈显示不清的情况下,VE图像可显示瘤颈并测量瘤颈直径。结论:在VR重建图像显示动脉瘤瘤颈不清的情况下,使用VE重建进行动脉瘤瘤颈直径的测量更加直观、准确。VE重建是VR重建技术的有力补充,可为动脉瘤的介入治疗提供更多信息。Objective：To investigate the clinical value of DSA volume endoscopy （VE）technique in interventional procedure for the treatment of cerebral aneurysm.Methods：Retrospective analysed the images of 21 patients with cerebral aneurysm during treatment with interventional procedures.Using GE ADW4.4 workstation to perform volume rendering （VR）and VE reconstruction of the raw data.After confirming the position during operation,the diameter of aneurysmal neck was measured on VE and VR reconstructed images respectively.Analysis and comparison of the results were per-formed.Results：Of the 21 patients,there were 10 cases had the neck of aneurysm clearly displayed on VE images,while not clearly displayed on VR.The diameter of aneurysmal neck was （3.13＆#177;1.09）mm on VR and （2.56 ＆#177;1.34）mm on VE re-spectively,with significant statistic difference （P ＆lt;0.05 ）.11 cases had the aneurysmal neck displayed clearly both on VE images and on VR images.The diameter of aneurysmal neck was （2.95＆#177;1.39）mm on VR and （2.92＆#177;1.48）mm on VE re-spectively,with no significant statistic difference （P ＆gt;0.05）.In all 21 cases,the diameter of the aneurysmal neck was （3.04 ＆#177;1.23）mm on VR and （2.75＆#177;1.39）mm on VE,with significant statistic difference （P ＆lt;0.05）.VE images can display the neck of aneurysm when VR images did not.Conclusion：In the process of interventional embolization,the aneurysmal neck can be measured accurately by VE reconstruction,which is more objective and accurate.VE reconstruction is a useful com-plementary technique for VR,which could provide more information for the interventional treatment of cerebral aneurysm.
