Hydrocephalous

Hydrocephalous is excessive water inside the brain or obstruction to the normal flow of Cerebrospinal fluid (CSF) in brain. It usually affects infants and older adults. The excessive amount of fluid put pressure on brain and can cause brain damage. Increase in CSF might lead to headache, vomiting and blurring of vision. In infants, it can occur due to birth defects or be acquired later in life. The other causes include meningitis, brain tumors, traumatic brain injury and hemorrhage. Hydrocephalous is treated by inserting Ventriculo-Peritneal shunt to bypass CSF into the abdomen or by Endoscopic third ventriculostomy, both procedures have pros/cons.

Common signs include headaches, vomiting, blurring of vision, and, in infants, an enlarged head. Causes range from birth defects to acquired reasons such as infections (e.g., meningitis), brain tumors, traumatic brain injury, and hemorrhage. Diagnosis is confirmed with brain imaging, such as an ultrasound, CT scan, or MRI.

Treatment Options

  • Ventriculoperitoneal (VP) Shunt: A flexible tube is inserted to divert CSF from the brain to the abdomen for absorption. Patients need regular monitoring for shunt function and possible complications.

  • Endoscopic Third Ventriculostomy (ETV): The surgeon creates a small hole in the floor of the third ventricle to allow blocked CSF to flow out of the brain.
    Both techniques have their own pros and cons and may be selected based on age, cause, and patient condition. With early intervention and proper care, most people can achieve good symptom control and quality of life.

Frequently asked questions

It is excess buildup of brain fluid, mainly affecting infants and older adults, but it can occur at any age.

Headache, vomiting, blurred vision, changes in memory, coordination difficulties, and in infants, rapid head growth.

Causes include birth defects, infections like meningitis, brain tumors, trauma, and brain hemorrhage.

By surgical placement of a VP shunt or by endoscopic third ventriculostomy, both allowing fluid drainage from the brain.

While surgical treatment can control symptoms and prevent complications, most patients require lifelong follow-up.
