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

摘要:

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。

Abstract:

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 surgi－cal 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-resolu－tion 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.
