目的 探讨C臂CT(Dyna CT)技术在颅内支架置入术中的应用价值.方法 选取39例行颅内支架置入术的患者,术中应用C臂CT技术扫描实时评价颅内支架置入情况.结果 39例患者共置入47枚支架,术中常规造影确认支架位置适当,再经C臂CT多平面重建得到影像显示证实支架贴壁良好.结论 应用C臂CT技术可以术中实时及术后很好显示支架轮廓以及管腔内的情况,进一步了解支架与周围组织的关系.该技术评估支架置入情况具有非常高的临床实用价值.%Objective To evaluate the clinical application of DynaCT technique in performing intracranial stent implantation. Methods Thirty-nine patients who were planed to receive intracranial stent implantation were involved in this study. During the procedure DynaCT scanning was employed to monitor the real-time situation of stent implantation. Results A total of 47 stents were implanted in intracranial vessels in the 39 patients. By using conventional angiography during operation the position of these stents was observed and was assured to be in the proper position. The adherence of these stents to the vascular wall was demonstrated with DynaCT multi-planar reconstruction images and the stent adherence in good condition was ensured. Conclusion DynaCT applied during and after intracranial stent implantation is very helpful for displaying the contours of the stents as well as the vascular lumen and for providing a detail picture of the relationship between the stent and the surrounding anatomy. Therefore, DynaCT scanning is of great clinical signif'icance for performing the intracranial stent implantation. (J Intervent Radiol, 2011 , 20 : 314-318)
