WebVentriculoperitoneal shunt (VPS) surgery remains the most widely accepted and used option method to treat post-hemorrhagic hydrocephalus (PHH) worldwide while lumboperitoneal shunt (LPS) serves as an effectively alternative treatment. However, the outcomes of VPS and LPS in the treatment of PHH have not been compared in a prospective trial. WebA surgeon will do the VP shunt placement in an operating room. Your child will get anesthesia to sleep during the surgery and not feel pain. A small area of hair might be shaved, then the surgeon will make small incisions (cuts) in the scalp. After making a small hole in the skull, the surgeon will place the tip of the catheter into the brain.
