海马硬化患者脑室周围白色物质氟马西尼结合和术后结果Hammers A,Koepp MJ,布鲁克斯DJ,邓肯JSE癫痫2005;46(6):944- 948目的在海马硬化(HS)患者中,前颞叶切除术为三分之二的患者提供了长期抑制癫痫发作的可能性。白色物质(WM)[11 C]氟马西尼分布容积(FMZ-Vd)反映WM中神经元细胞体的数量。我们的目的是相关的WM FMZ-Vdin患者与单侧HS和postsurgical outcome.MethodsWe进行[11 C]氟马西尼正电子发射断层扫描([11 C]FMZ-PET)在15例难治性内侧颞叶癫痫(mTLE)和定量MRI诊断单侧HS随后在所有情况下组织学验证。中位随访时间为7年(范围:6-9年)。使用代谢物校正的动脉血浆输入函数和光谱分析生成[11 C]FMZ-Vd的参数图像。统计参数映射(SPM 99)与明确的掩蔽被用来调查整个脑容量,包括WM.Results8例恩格尔IA类的结果(完全无瘤,因为手术),和7个没有无瘤。无癫痫患者与那些谁继续有癫痫发作手术后的比较显示,增加FMZ结合周围的同侧(z = 3.7)和对侧(z = 2.7)ventricles在那些次优outcomes.ConclusionsPreoperative [11 C]FMZ-PET可以检测到脑室周围的WMFMZ结合的增加,这意味着在WM异位神经元,在mTLE患者。这种增加的存在与较差的结果相关。
Periventricular White Matter Flumazenil Binding and Postoperative Outcome in Hippocampal SclerosisHammers A, Koepp MJ, Brooks DJ, Duncan JSEpilepsia2005;46(6):944–948PurposeIn patients with hippocampal sclerosis (HS), anterior temporal lobe resection offers the possibility of a long-lasting suppression of seizures in two-thirds of patients. White matter (WM) [11C]flumazenil volume of distribution (FMZ-Vd) reflects the number of neuronal cell bodies in WM. Our objective was to correlate WM FMZ-Vdin patients with unilateral HS and postsurgical outcome.MethodsWe performed [11C]flumazenil positron emission tomography ([11C]FMZ-PET) in 15 patients with refractory mesial temporal lobe epilepsy (mTLE) and a quantitative MRI diagnosis of unilateral HS subsequently histologically verified in all cases. Median follow-up was 7 years (range, 6–9 years). Metabolite-corrected arterial plasma input functions and spectral analysis were used to generate parametric images of [11C]FMZ-Vd. Statistical parametric mapping (SPM99) with explicit masking was used to investigate the entire brain volume including WM.ResultsEight patients had Engel class IA outcome (completely seizure-free since surgery), and seven were not seizure-free. Comparison of seizure-free patients with those who continued to have seizures after surgery revealed areas of increased FMZ binding around the posterior horns of the ipsilateral (z = 3.7) and contralateral (z = 2.7) ventricles in those with suboptimal outcomes.ConclusionsPreoperative [11C]FMZ-PET can detect periventricular increases of WMFMZ binding, implying heterotopic neurons in WM, in patients with mTLE. The presence of such increases correlates with a poorer outcome.
