脑微出血（CMB）的梯度回忆回声（GRE）磁共振成像（MRI）在儿童中很少见，但在成人血管手术后被描述。体外膜氧合（Extracorporeal membrane oxygenation， ECMO）与儿童血管损伤和神经系统事件有关，但迄今为止还没有关于接受ECMO治疗的儿童的GRE MRI结果的报道。我们回顾了一家学术医疗中心5年来所有接受体外膜肺氧合治疗的儿童血管神经学咨询的MRI扫描。在12例中，有6例是获得性GRE，其他病例不稳定或有MRI禁忌症。6例（100%）GRE病例（平均年龄2.1岁，7例女性，5例男性）均表现为CMB。CMB为多发病变（bbbb3），位于皮质或脑叶区，颈动脉右侧分布明显占优势（5/6例）。除CMB外，无颅内出血。在ECMO后的GRE MRI上可以发现CMB，可能反映了气体栓塞引起的血管损伤。
Cerebral microbleeds (CMB) on gradient-recalled echo (GRE) magnetic resonance imaging (MRI) are rarely seen in children, yet have been described following vascular procedures in adults. Extracorporeal membrane oxygenation (ECMO) has been associated with vascular injury and neurological events in children, but there have been no reports to date of GRE MRI findings in children treated with ECMO. We reviewed MRI scans for all vascular neurology consultations in children treated with ECMO at an academic medical center over a 5-year period. In 6 of 12 cases, GRE was acquired as others were unstable or had contraindications to MRI. All 6 of 6 (100%) GRE cases (mean age 2.1 years, 7 female, 5 male) demonstrated CMB. CMB were multiple (>3 lesions), situated in cortical or lobar regions, with a striking predominance (5/6 cases) for the right carotid distribution. Other than CMB, no cases demonstrated intracranial hemorrhage. CMB may be noted on GRE MRI after ECMO and may reflect vascular damage from gaseous emboli.
