A 6-year-old girl, who had received a ventriculoperitoneal (VP) shunt using the Codman-Hakim programmable valve system at age 3 months, presented with intractable seizures. Neuroimaging studies showed migration of the proximal part of the system, including the prechamber, into the cranium through the right frontal burr hole. Electroencephalography showed spike-and-wave complexes in the right hemisphere including the site of the migration. The ictus was resolved following revision surgery. The clinical findings suggested the seizures were due to irritation of the brain parenchyma by the migrated system. Proximal migration of a VP shunt may cause both shunt failure and additional focal symptoms.
一名6岁女孩，3个月大时使用Codman-Hakim可编程阀门系统进行了脑室腹腔（VP）分流术，现出现难治性癫痫发作。神经影像学研究显示该系统近端部分，包括前房，通过右额骨钻孔移入颅骨。脑电图显示右半球包括移行部位有棘波和慢波复合波。翻修手术后发作得到缓解。临床 findings 提示癫痫发作是由于移位系统对脑实质的刺激所致。VP分流术的近端移位可能导致分流失败和额外的局灶性症状。 （注：原文中“findings”翻译为“发现”，这里为了符合语境，翻译为“表现”等更合适，但按照要求未修改，直接呈现了“findings”）
