【摘要】 目的 探讨高分辨率C形臂CT扫描联合金属条纹伪影消除技术(SMART)在颅内动脉瘤介入治疗术中的应用价值,并评价其有效性。 方法 2018年1月至5月郑州大学第一附属医院郑东院区采用支架辅助弹簧圈栓塞连续治疗41例(42枚)颅内动脉瘤患者,术中和术后对支架置入区域分别作常规DynaCT和高分辨率Dyna microCT扫描,扫描图像经常规重建和SMART重建。2名神经介入专家对重建图像质量(支架金属丝显影程度、弹簧圈金属伪影程度等),并结合操作位造影对支架打开程度、动脉瘤栓塞致密程度等,进行观察和定量统计分析。结果 42枚颅内支架(Neuroform EZ支架26枚,低剖面可视化腔内支架LVIS 16枚)顺利辅助完成42枚动脉瘤栓塞(40例患者为单枚,1例为双枚)。与常规DynaCT重建和Dyna microCT重建相比,Dyna microCT联合SMART重建图像所示支架金属丝显影清晰,弹簧圈金属伪影消除明显,图像质量显著提高(P<0.05)。根据后者重建图像并结合操作位造影发现2枚支架局部打开不全,给予微导丝成襻支架内抚摸或球囊扩张后贴壁情况改善;4例患者瘤颈区栓塞未致密,调整微导管头端位置后继续栓塞术,直至栓塞效果满意。结论 高分辨率Dyna microCT联合SMART能有效降低颅内动脉瘤栓塞术中支架和弹簧圈金属伪影,提高图像质量,有利于术者判定载瘤动脉内金属支架打开情况和动脉瘤瘤颈区栓塞是否致密,继而选择相应的治疗策略。这种新颖成像技术对于颅内动脉瘤介入治疗中评估具有较大应用价值。
