Hydrocephalus, a condition characterized by an abnormal accumulation of cerebrospinal fluid (CSF) in the brain, can lead to increased intracranial pressure and resultant neurological complications. The most effective and permanent treatment for hydrocephalus involves surgical intervention. In this article, we will explore the key surgical treatment options for this condition.
Temporary measures such as external ventricular drainage (EVD) are often utilized in scenarios where the underlying cause of hydrocephalus is transient. For instance, acute hydrocephalus due to bleeding into the ventricular system can be managed using EVD, where a catheter is placed into the ventricular system to drain CSF outside, thereby relieving pressure and improving the patient's condition.
In some cases, direct elimination of the obstruction causing hydrocephalus, such as a tumor or cyst, can effectively cure the condition. However, in a significant number of instances, the underlying cause cannot be eradicated, necessitating treatment directly addressing the hydrocephalus itself.
Two types of surgery predominantly serve this purpose: shunting and endoscopic third ventriculostomy (ETV).
The more common of the two procedures, shunting, involves the implantation of a device to redirect CSF from the brain to another part of the body for absorption, often the abdominal cavity— a procedure known as ventriculo-peritoneal shunting.
The shunt usually comprises three parts: a ventricular catheter, a valve, and a peritoneal catheter. The ventricular catheter is inserted into the brain ventricles through a small hole in the skull, while the peritoneal catheter is placed under the skin, extending from the head to the abdomen, where it is then placed into the abdominal cavity. These catheters are connected by a valve, which facilitates fluid drainage when the pressure rises.
ETV offers an alternative surgical solution, creating an artificial window to allow the CSF to bypass the blockage. A thin endoscope is inserted into the ventricle through a small hole in the skull. The endoscope is advanced into the third ventricle, where a window is created in the ventricle floor, allowing the CSF to flow directly into the subarachnoid space.
Both shunting and ETV provide effective means to treat hydrocephalus. Shunting's main disadvantage lies in the implantation of a foreign device, which stays in the patient's body for the rest of their life. It may get infected or experience mechanical failure. ETV, although elegant and simple, is most effective when hydrocephalus results from a blockage of fluid flow.
Following hydrocephalus surgery, patients usually experience a significant improvement in their symptoms. However, the recovery journey is different for each individual. Patients often need to stay in the hospital for a few days for close medical supervision.
During the initial recovery phase, discomfort and headaches are common but can be managed effectively with prescribed medications. Gradually, patients can start to resume their regular activities, while adhering to the prescribed rehabilitation plan. This plan may include physical therapy sessions to aid the healing process.
Regular follow-up appointments with the neurosurgeon are critical to monitor the patient's progress, manage any post-operative complications, and make necessary adjustments to the treatment plan.
In some cases, despite successful surgery, patients might continue to experience persistent symptoms, or additional surgeries might be necessary. Patience is crucial during the recovery period, as the healing process post-brain surgery typically spans weeks to months.
Importantly, emotional support, including counseling or participation in support groups, can be very beneficial during recovery. Dealing with a neurological condition like hydrocephalus can be emotionally challenging, and recovery involves not just physical healing, but psychological well-being too.
Every patient's recovery journey is unique, and open communication with healthcare providers can help address any concerns and questions along the way.
Common symptoms of a brain tumor can vary greatly and depend on the tumor's location, size, and growth rate. They may include headaches, seizures, changes in personality or behavior, memory problems, and difficulty with balance, speech, hearing, or vision.

Treatment options for a pituitary adenoma include observation, medication, surgery, and radiation therapy. The best treatment option depends on the size and type of the tumor, the patient's overall health, and personal preferences.

Scoliosis treatment depends on the degree of the curve and the patient's age. Non-surgical treatments include physical therapy, brace use, and pain relievers. In severe cases, surgery may be required to correct the curve. Learn more about scoliosis is treated in our Scoliosis Treatment section.Learn More
The diagnosis of TOS is made in conjunction with the patient's history, symptoms, physical examination, imaging tests, and neurophysiological tests. Treatment can include physical therapy, pain management, and surgery in severe cases. Learn more about treatment options in our Thoracic Outlet Syndrome Treatment section.Learn More
Warning signs of a brain aneurysm can encompass sudden and severe headaches, blurred or double vision, neck pain, fainting or dizziness, and sensitivity to light. However, many aneurysms may not show symptoms until they leak or rupture. Learn more about this in our Brain Aneurysms section.Learn More
The need for surgery typically depends on the size, location, and growth rate of the aneurysm. Generally, aneurysms larger than 7mm, those located at certain parts of the brain, or those showing signs of growth on consecutive scans may require surgical intervention. To understand the specifics, it's best to consult with a neurosurgeon. More on this topic in our Brain Aneurysms section.Learn More
Currently, there's no standard blood test that can definitively diagnose brain cancer. While certain markers or changes may suggest a tumor's presence, imaging tests like MRI or CT scans remain primary diagnostic tools.

The growth rate of brain tumors can vary based on the type and grade of the tumor. Some tumors grow slowly and might not cause symptoms for years, while others can grow rapidly and present symptoms within weeks or months. The onset of symptoms also depends on the tumor's location and size. Learn more about the progression of brain tumors in our Brain Cancer section.Learn More
After brain surgery, patients might experience fatigue, mood fluctuations, or cognitive changes. Recovery time varies, and regular follow-ups are essential to monitor healing and detect any complications.

As we age, the spine undergoes natural degenerative changes. Discs may lose hydration and elasticity, vertebral bones might thin, and there can be a gradual narrowing of the spinal canal, which might lead to spinal stenosis or other conditions.

Recovery from vertebroplasty is typically quick, with most patients resuming normal activities within a few days.Learn More
Both procedures involve stabilizing fractured vertebrae, but kyphoplasty includes the inflation of a balloon to create space before cement is injected, whereas vertebroplasty injects cement directly without balloon inflation.Learn More
Patients with certain types of fractures, severe osteoporosis, or those with an active infection might not be suitable candidates for kyphoplasty. Always consult with a spinal specialist.Learn More
The three primary types of scoliosis are idiopathic (cause unknown, most common in adolescents), congenital (due to bone abnormalities present at birth), and neuromuscular (stemming from nerve or muscle disorders).
