Over-drainage after a ventriculoperitoneal (VP) shunt can often lead to chronic subdural hematoma; however, the treatment is unclear. Hematoma drainage is performed after physically stopping the shunt function, such as by ligating or removing the shunt system. However, shunt reconstruction is required after the subdural hematoma improves. This study investigated the usefulness of a programmable valve with virtual off-function for chronic subdural hematoma after VP shunt surgery. We installed a programmable valve with a virtual off-function for chronic subdural hematoma after VP shunt surgery. A programmable valve with a virtual off-function is a valve system that can stop and restart the shunt function at will. After the subdural hematoma has improved, shunt function can be resumed, and pressure can be set to an optimal level. Installing a programmable valve with a virtual off-function is useful as a new treatment method to address over-drainage complications while preserving shunt function.
脑室腹腔（VP）分流术后过度引流常可导致慢性硬膜下血肿；然而，其治疗方法尚不清楚。在通过结扎或移除分流系统等物理方式停止分流功能后进行血肿引流。然而，硬膜下血肿改善后需要进行分流重建。本研究调查了具有虚拟关闭功能的可编程阀门对VP分流术后慢性硬膜下血肿的有效性。我们为VP分流术后慢性硬膜下血肿安装了具有虚拟关闭功能的可编程阀门。具有虚拟关闭功能的可编程阀门是一种能够随意停止和重启分流功能的阀门系统。硬膜下血肿改善后，可恢复分流功能，并将压力设定至最佳水平。安装具有虚拟关闭功能的可编程阀门作为一种新的治疗方法，在保留分流功能的同时解决过度引流并发症是有用的。
