摘　　要：目的探讨基于3D-DSA双容积重建的单模融合技术在颅内动脉瘤栓塞术后随访中的应用价值。方法回顾性分析2013年5月至2015年4月经血管内颅内动脉瘤栓塞术后随访的137例患者的临床及全脑血管造影检查资料。结果137例患者中共152个颅内动脉瘤,其中多发颅内动脉瘤患者15例。所有患者均行血管内栓塞术治疗,其中117个颅内动脉瘤行单纯弹簧圈栓塞治疗,35个行支架辅助弹簧圈栓塞。随访发现动脉瘤完全闭塞123个(80.9%),瘤颈残留17个(11.2%),瘤腔残留12个(7.9%)。结论基于3D-DSA双容积重建的单模融合技术能够更好发现颅内动脉瘤栓塞术后残留或复发,并能排除金属伪影的干扰,提供更直观、清晰的重建影像,在DSA随访中具有重要应用价值。Objective To evaluate the application of three-dimensional fusion digital subtraction angiography （3D-DSA） in postoperative follow up of patients with intracranial aneurysm embolization. Methods One hundred and thirty seven patients with intracranial aneurysm （152 lesions）, including 42 males and 95 females aged 24-81 years, were treated with endovascular embolization （coil embolization for 117 aneurysms, covered-stent placement for 35 aneurysms） from May 2013 to April 2015. The patients underwent three-dimensional fusion digital subtraction angiography during postoperative follow up, and the angiographic findings were retrospectively analyzed. Results Follow-up found that among 152 aneurysms, 123 were embolized completely, 17 had neck remnants and 12 had dome remnant. Conclusion Three-dimensional fusion DSA can eliminate the interference of the metal artifacts and provide more intuitive, clear and the restructuring images, it is of value in follow-up of patients with intracranial aneurysm embolization.
