【摘要】 目的 探讨双容积重建技术(double volume reconstruction technique, DVRT)在颅内动脉瘤介入栓塞术后随访中的应用价值。方法 选取动脉瘤介入栓塞术的36例患者行常规脑血管造影(2D-DSA),对栓塞治疗的血管行三维数字减影血管造影(3D-DSA),并进行双容积重建，重点观察三者对栓塞动脉瘤残留的检出情况。结果 36例患者中2D-DSA检查显示完全栓塞26例，瘤颈残留6例，瘤体残留4例；3D-DSA显示完全栓塞17例，瘤颈残留11例，瘤体残留8例；双容积重建图像显示完全栓塞15例，瘤颈残留12例，瘤体残留9例。2D-DSA与双容积重建对动脉瘤残留诊断的比较差异有统计学意义(Z=-2.54,P<0.05);3D-DSA与双容积重建比较差异无统计学意义(Z=-0.45,P>0.05)。结论 DVRT可清晰显示出对比剂在弹簧圈中显影的程度以及位置，在评价弹簧圈栓塞的效果上能提供比2D-DSA、3D-DSA更丰富的影像学信息。更多还原

【Abstract】 Objective To explore the value of double volume reconstruction technique in follow-up of intracranial aneurysm with interventional treatment. Methods 36 patients with aneurysm embolization were examined with conventional cerebral angiography(2D-DSA), while the vascular with aneurysm embolization was conducted three-dimensional digital subtraction angiography(3D-DSA), and then double volume was reconstructed, the detection of aneurysm remnant was carefully observed. Results Of the 36 cases, 2D-DSA did not show aneurysm remnant in 26 cases, aneurismal neck remnant was displayed in 6 cases, aneurismal body remnant was detected in 4 cases; 3D-DSA did not show aneurysm remnant in 17 cases, aneurismal neck remnant was displayed in 11 cases, aneurismal body remnant was detected in 8 cases; double volume reconstruction image did not show aneurysm remnant in 15 cases, aneurismal neck remnant was displayed in 12 cases, aneurismal body remnant was detected in 9 cases. There was a statistical significance between 2D-DSA and double volume reconstruction image(Z=-2.54, P<0.05) when detecting an aneurysm remnant; and there was no significant difference between 3D-DSA and double volume reconstruction(Z=-0.45, P>0.05). Conclusion The double volume reconstruction technique can clearly show the degree and position of the contrast medium within the coils, which can provide much more imaging information than 2D-DSA and 3D-DSA in evaluating the embolization effectiveness.更多还原
