颅内动脉瘤栓塞术后随访中3D—DSA双容积重建的单模融合技术的应用效果观察

Observation on the effect of 3D-DSA dual-volume rendering in the follow-up of intracranial aneurysm embolization

目的研究颅内动脉瘤栓塞术后随访中3D—DSA双容积重建的单模融合技术的应用效果。方法采用抽签模式将于本院行颅内动脉瘤栓塞的患者中随机抽选出53例，均以术后随访的形式来观察患者术后颅内状况。结果53例患者总共有颅内动脉瘤60个，所有患者均接受血管内栓塞术的治疗，其中，21例患者行支架辅助弹簧圈栓塞术，32例患者行单纯弹簧圈栓塞术。随访后发现瘤腔残留4个，占6．67％；瘤颈残留10个，占16．66％；动脉瘤完全闭塞有46个，占76．67％。结论将3D—DSA双容积重建的单模融合技术应用于颅内动脉瘤栓塞术后随访中，能有效明确患者在行颅内动脉瘤栓塞术后，其颅内肿瘤是否有复发或残留现象，并有效排除金属伪影之类的干扰因素，确保患者影像重建的可视程度更为清晰和直观，在随访中具有较高的应用价值，值得推广。

Objective To study the effect of 3D-DSA dual-volume rendering in the follow-up of intracranial aneurysm embolization. Methods 53 cases were randomly selected from patients with intracranial aneurysm embolization in our hospital. All the patients were followed up for the postoperative intracranial condition. Results There were 60 intracranial aneurysms in 53 patients. All patients underwent endovascular embolization, in whom 21 patients underwent stent-assisted coil embolization and 32 patients underwent simple coil embolization. Tumor cavity residual accounted for 6.67% （4/60） during the follow up, tumor neck residual accounted for 16.66% （10/60）, and aneurysm completely occluded accounted for 76.67% （46/60）. Conclusions 3D-DSA dual-volume rendering of single-mode fusion technique in the follow-up can be used to determine whether the intracranial tumor has relapse or residual after intracranial aneurysm embolization, and effectively eliminate the interference factors such as metal artifacts to ensure that the visualization of the patients＇ image reconstruction is more clear and intuitive, has a high value in the follow-up, worthy of promotion.
