PLoS One:Moyamoya病患者的低灌注区在静息态fMRI会有什么改变呢?

2017-07-06 shaosai MedSci原创

Moyamoya病是一种慢性渐进性进展的疾病,在一定程度上会发生急性缺血性脑卒中。该病的特点是在双侧颈内动脉末端及颈内动脉系分支起始段管腔向心性狭窄并有相应区域的迂曲增多的侧支循环形成。在脑灌注加权成像(PWI)中往往会显示病变区域的低灌注状态。而慢性脑低灌注病变在静息态血氧水平依赖性功能磁共振(rest-fMRI)上所引起的信号改变尚不清楚。

Moyamoya病是一种慢性渐进性进展的疾病,在一定程度上会发生急性缺血性脑卒中。该病的特点是在双侧颈内动脉末端及颈内动脉系分支起始段管腔向心性狭窄并有相应区域的迂曲增多的侧支循环形成。在脑灌注加权成像(PWI)中往往会显示病变区域的低灌注状态。而慢性脑低灌注病变在静息态血氧水平依赖性功能磁共振(rest-fMRI)上所引起的信号改变尚不清楚。

本研究旨在确定慢性脑缺血是否会引起低频波动振幅(ALFF)的变化,并研究在moyamoya病(MMD)患者中ALFF与PWI参数之间的相关性,并将结果发表在PLoS One上。

本研究共纳入了30例术前和术后均行rest-fMRI和PWI检查的患者以及30例进行rest-fMRI检查的健康志愿者。 rest-fMRI显示在MMD患者术前额叶的ALFF减低,而在术后额叶ALFF显示有中度改善,但仍低于正常对照组。 平均通过时间(MTT)和达峰时间(TTP)与额叶ALFF具有显着的相关性,而脑血容量(CBV)和脑血流量(CBF)与额叶ALFF并无明显相关性。 此外,通过单侧血运重建手术后,额叶PWI各参数变化与双侧额叶ALFF变化均呈显着负相关。

本研究结果表明,ALFF降低与PWI参数异常具有明显相关性,随MMD患者脑灌注改变而变化。

STROKE:对Moyamoya病患者来说,做个EC-IC旁路重建术会累及认知功能吗?

采用EC-IC旁路进行脑实质血运重建技术被广泛用于治疗moyamoya病,但该手术对患者认知的影响是尚不明确。
