Document challenges of cochlear implantation in the presence of a ventriculoperitoneal shunt (VPS) with a programmable valve.
A 7-month-old, postmeningitic, hydrocephalic infant with profound sensorineural hearing loss.
Ventriculoperitoneal shunt revision with a nonprogrammable valve and bilateral cochlear implantation. Magnetic fields generated by cochlear implant (CI) transmitting coil magnets were measured ex vivo.
Successful implantation and elimination of potential hazardous interaction between CI and VPS.
Index patient reviewed and magnetic field strength presented.
Strong magnetic fields can potentially alter the pressure setting of programmable shunt valves, causing overdrainage or underdrainage and potential serious consequences. Clear communication between the involved medical specialties is required for optimal management of patients requiring both VPS and CI.
记录在存在带有可编程阀门的脑室腹腔分流术（VPS）的情况下进行人工耳蜗植入的挑战。
一名7个月大、患过脑膜炎、脑积水且患有重度感音神经性听力损失的婴儿。
用不可编程阀门进行脑室腹腔分流术修复及双侧人工耳蜗植入。在体外测量了人工耳蜗（CI）发射线圈磁体产生的磁场。
成功植入以及消除CI与VPS之间潜在的有害相互作用。
对索引患者进行了复查并呈现了磁场强度。
强磁场可能会改变可编程分流阀的压力设置，导致引流过度或引流不足，并可能产生严重后果。对于同时需要VPS和CI的患者，相关医学专科之间需要进行清晰的沟通以实现最佳管理。
