摘要
目的探讨双容积重建透明影像在支架结合弹簧圈栓塞颅内动脉瘤中的应用价值。方法2011年11月—2012年9月收治颅内动脉瘤患者30例,行颅内支架结合弹簧圈栓塞治疗。比较患者常规二维造影(2D-DSA)、三维旋转造影(3D-RA)和双容积重建透明影像能显示的支架标记点数目。结果30例患者共植入34枚支架,在所有支架的206个标记点中,2D-DSA、3D-RA和双容积透明影像能清晰显示的标记点分别为146(70.8%)、123(59.7%)和190个(92.2%),三种造影方法间的支架标记点的显示率差异有统计学意义(P<0.05)。结论双容积重建透明影像能清晰显示颅内支架的标记点,在颅内支架的植入术中有巨大的应用价值。
Objective To investigate the application of dual volume reconstruction translucent imaging in performing stent- assisted coil embolization for intracranial aneurysm embolization treatment. Methods During the period from Nov. 2011 to Sep. 2012, a total of 30 patients with intracranial aneurysm were admitted to authors’ hospital. Stent-assisted coil embolization was carried out in all patients. The number of all the stent point-marks visualized on routine 2D-DSA, on rotational angiography (3D-RA) and on dual volume reconstruction translucent images were determined, and the results were compared between each other of the three imaging methods. Results A total of 34 stents (206 stent point-marks in total) were implanted in the 30 patients. Of the 206 stent point-marks, 2D-DSA, 3D-RA and dual volume reconstruction translucent image could clearly display 146 (70.8%), 123 (59.7%) and 190 (92.2%), respectively. Statistically significant difference in the displaying rate of the stent point-marks existed between each other among the three imaging methods (P 〈 0.05). Conclusion Dual volume reconstruction translucent imaging can distinctly display the location of the stent marks, which is of great value in guiding the performance of intracranial stent implantation surgery.
