## Core Concept
Congenital hydrocephalus is a condition characterized by an accumulation of cerebrospinal fluid (CSF) within the brain, leading to increased intracranial pressure and enlargement of the cerebral ventricles. It often results from an imbalance between CSF production and absorption, or from obstruction of CSF pathways. Treatment aims to alleviate symptoms, reduce intracranial pressure, and prevent further brain damage.

## Why the Correct Answer is Right
The correct approach for treating congenital hydrocephalus often involves surgical intervention to facilitate the drainage of CSF. **Ventricular shunt placement** is a common and effective treatment, where a shunt device is implanted to drain excess CSF from the ventricles to other parts of the body, such as the abdomen, where it can be absorbed. This procedure helps to reduce intracranial pressure and can improve neurological function.

## Why Each Wrong Option is Incorrect
- **Option A:** While certain medications may be used to manage symptoms or to treat underlying causes, they are not the primary treatment for congenital hydrocephalus.
- **Option B:** Conservative management might include monitoring and supportive care but does not address the underlying issue of CSF accumulation and is not sufficient as a standalone treatment for congenital hydrocephalus.
- **Option D:** Endoscopic third ventriculostomy (ETV) is a surgical option for some cases of hydrocephalus, particularly those with obstructive hydrocephalus, but it may not be suitable or effective for all types of congenital hydrocephalus.

## Clinical Pearl / High-Yield Fact
A key point to remember is that **ventricular shunt placement** is a lifesaving procedure for many patients with congenital hydrocephalus, but it requires careful monitoring and may need revisions over time due to complications such as shunt failure or infection.

## Correct Answer Line
**Correct Answer: C. Ventricular shunt placement**
