There are two known surgical hydrocephalus treatment available: placing a shunt or performing an endoscopic third ventriculostomy. Both methods effectively relieve the excess fluid surrounding the brain and, in turn, the pressure. Take a closer look at this disease, how we determine an appropriate treatment, and what to expect during each.
Hydrocephalus is a serious condition in which excess cerebrospinal fluid builds up in the brain's ventricles. The ventricles already have fluid, helping the brain function properly, receive nutrients, drive out waste, and act as a shock absorber. When there becomes too much, it can lead to:
According to the American Association of Neurological Surgeons (AANS), there are many more signs an individual can experience with hydrocephalus. Some are also more prominent in children, while others are more prominent in adults. Per the National Institute of Neurological Disorders and Stroke (NINDS), hydrocephalus affects one to two in every 1000 children and is typically diagnosed right after birth or in early childhood.
It is good to note that patients can experience different forms of hydrocephalus. It can result from a developmental disorder, head or spinal trauma, or be inherited. Moreover, while some symptoms are rather obvious, the surgeon will still need to perform a consultation to determine which surgical method is most suitable. The surgeon will perform a complete neurological examination in addition to imaging tests, a lumbar (spinal) tap, intracranial pressure monitoring, and an isotope cisternography.
The most common hydrocephalus treatment is inserting a shunt in the skull. A shunt is a device that diverts the excess cerebrospinal fluid away from the brain. Its design consists of a catheter (flexible tube) and a valve.
During the procedure, the surgeon will shave the hair over the surgical area. They then create an incision flap in the skull, allowing clear access to the skull and another in the belly or chest for later use. The surgeon then drills a hole in the skull to pass the catheter through the ventricles of the brain. Sometimes, the surgeon will use a computer to guide them through the process, allowing them to see inside the ventricles, but this is not always necessary.
Another catheter travels down through the chest and stops at the belly—sometimes, it can stop at the chest. The valve is placed just underneath the skin, usually behind the ear, to connect both catheters and allow the fluid to flow properly. When pressure builds up in the brain, the valve will open, allowing the excess fluid to flow down to the catheter in the belly or chest. The valve will have a reservoir, which helps it to pump and collect cerebrospinal fluid if needed. Parents should note that the shunt will remain in the child's body for the remainder of their life.
The second hydrocephalus treatment is called endoscopic third ventriculostomy. It is considered a rare surgical method because not everyone is a candidate. The surgeon uses a camera and computer to visualize the ventricle and surrounding area. They then create an entirely new pathway for the cerebrospinal fluid to flow. If this option is more suitable for the candidate, the surgeon will share more information on the procedure steps.
