高分辨率3D CE-MRV联合3D T1增强在SEEG手术计划中的应用

Value of high-resolution three-dimensional contrast-enhanced magnetic resonance venography combined with three-dimensional T1-weighted magnetic resonance imaging in surgical planning for stereotactic electroencephalography

目的:探讨利用高分辨率3D CE-MRV联合3D T1增强在SEEG手术计划的可行性及准确性。方法:对计划行SEEG手术的12例药物难治性癫痫患者进行定制的MRI检查,利用iplan软件制定手术计划,共植入89根电极,分析手术结果。结果:12例患者共89根电极均顺利植入,术后未发生出血。其中包括2例岛叶癫痫的患者。结论:高分辨率3D CE-MRV有助于寻找无血管通道,3D T1增强有助于了解针道所经过的脑组织结构,两者联合使用可以准确地制定手术计划,减少手术并发症。

Objective:To investigate the feasibility and accuracy of high-resolution three-dimensional contrast-enhanced magnetic resonance venography(3D CE-MRV) combined with three-dimensional T1-weighted magnetic resonance imaging(3D T1-weight MRI) in surgical planning for stereotactic electroencephalography. Methods:A total of 12 patients with medically intractable epilepsy who planned to undergo SEEG surgery were enrolled. Individualized MRI was performed,and the iPlan software was used to develop surgical plans. A total of 89 electrodes were implanted,and the results of the surgery were analyzed. Results:The 89 electrodes were successfully implanted,and no postoperative bleeding was observed. Of all patients,2 had insular epilepsy. Conclusion:High-resolution 3D CE-MRV helps to find the avascular trajectory and 3D T1-weight MRI helps to know the structure of brain tissue in the avascular trajectory. Their combination can accurately develop the surgical plan and reduce complications.
