急性婴儿偏瘫易并发于急性发热性疾病和局灶性惊厥,在这些儿童中,有的可相继发生永久的运动缺陷和癫癎。这种以偏侧抽搐和偏瘫开始,随后发生永久的运动缺陷和癫癎的疾病,Gastant等命名为H.H.E综合征(hemiconvulsions、hemiplegia、epilepsy)。对其病因的考虑包含病毒感染,动脉闭塞和静脉血栓形成,但都很少被实验室检查所证实。在这些病毒感染的小孩中,急性偏瘫的发病机制了解得很少,它被认为可能是病毒感染后引起局灶性血管炎,继发脑梗塞或是直接引起的脑组织软化过程。但无论那一种机制都缺乏放射和病理检查的证据。
Acute infantile hemiplegia is easily complicated by acute febrile illness and focal convulsions, and in these children, permanent motor deficits and epilepsy may occur one after the other. This type of hemiplegia, hemiplegia, epilepsy, begins with hemiplegia and hemiplegia, followed by permanent motor deficits and epilepsy. Gastant et al. Considerations for its etiology include viral infections, arterial occlusions, and venous thrombosis, but are rarely confirmed by laboratory tests. In children infected with these viruses, the pathogenesis of acute hemiparesis is poorly understood and is thought to be caused by focal vasculitis, secondary cerebral infarction or a direct result of brain tissue softening after viral infection. But neither mechanism lacks evidence of radiation and pathology.
