【摘要】：目的:探讨双容积图像融合技术在颅内动脉瘤介入血管内栓塞术中的应用价值。方法:对梅州市人民医院介入手术室2016年1-6月46例颅内动脉瘤破裂出血患者,栓塞前均行2D-DSA及3D-DSA检查,确定责任动脉瘤后行颅内动脉瘤介入栓塞术,术者认为栓塞满意后即刻行3D-DSA复查,应用数字减影三维重建技术中的双容积图像融合技术在AW(Advantage Workstation;GE Medical System)后处理工作站进行图像融合,评价动脉瘤栓塞的效果。结果:46例患者共发现52枚动脉瘤(4例为多发动脉瘤),均顺利进行介入栓塞术(其中38枚动脉瘤单纯行弹簧圈栓塞,14枚动脉瘤在支架或球囊辅助下栓塞),均在AW后处理工作站上完成图像融合,在融合图像的46例患者中:30例动脉瘤内无造影剂充填,10例瘤颈处见造影剂显影,瘤体部无造影剂显影,6例瘤体内见造影剂显影。结论:根据双容积图像融合技术来评估动脉瘤栓塞术后的残留情况来判断弹簧圈栓塞的致密程度及残留瘤腔大小,有助于术者判断动脉瘤栓塞术后是否继续进行栓塞或指导下一步的治疗方案,并且为以后的术后随访复查提供重要信息。
[Abstract]:Objective: to evaluate the value of double volume image fusion in interventional endovascular embolization of intracranial aneurysms. Methods: 46 patients with ruptured intracranial aneurysms were treated in the interventional operating room of Meizhou people's Hospital from 2016 to June 2016. Both 2D-DSA and 3D-DSA were performed before embolization, and 3D-DSA was performed immediately after the successful embolization. Using the double volume image fusion technology in the digital subtraction 3D reconstruction technology, the image fusion was carried out on the post processing workstation of AW(Advantage Workstation GE Medical system. Results A total of 52 aneurysms were found to be multiple aneurysms in 46 patients. All of them underwent interventional embolization successfully (among them 38 aneurysms were embolized by coils alone and 14 aneurysms were placed in stents or spheres). The image fusion was completed on the AW post processing workstation. In 46 patients with fusion images, contrast media were found in the neck of 10 patients without contrast media filling in 30 cases of aneurysms. Contrast agent was found in 6 cases of tumor without contrast agent. Conclusion: the density and residual size of coil embolization can be evaluated by double volume image fusion technique after embolization of aneurysm. It is helpful to judge whether the aneurysm should continue to be embolized or to guide the next treatment plan, and to provide important information for the follow-up and reexamination.
