AND
2. Child is ≥ 37 weeks post menstrual age,

AND
3. Child must have symptomatic hydrocephalus, defined as:

Ventriculomegaly on MRI (frontal-occipital horn ratio (FOR) \>0.45, which approximates "moderate ventriculomegaly"), and at least one of the following:
* Head circumference \>98th percentile for corrected age with either bulging fontanelle or splayed sutures

* Intracranial pressure (ICP) monitoring showing persistent elevation of pressure with or without plateau waves

AND
4. No prior history of shunt insertion or endoscopic third ventriculostomy (ETV) procedure (previous temporization devices and/or external ventricular drains permissible)

Exclusion Criteria:

1. Hydrocephalus due to intraventricular hemorrhage in a child born before 37 weeks gestational age; OR
2. Anatomy not suitable for ETV+CPC or anteriorly placed ventriculoperitoneal shunt defined as:

* Closure of one or both foramina of Monro
* Thick floor of third ventricle (≥ 3mm)
* Narrow third ventricle (\<5mm)
* Presence of scalp, bone, or ventricular lesions that make placement of an anterior shunt impracticable; OR
3. Underlying condition with a high chance of mortality within 12 months; OR
4. Hydrocephalus with loculated CSF compartments; OR
5. Peritoneal cavity not suitable for distal shunt placement; OR
6. Active CSF infection; OR
7. Hydranencephaly; OR
8. Child requires an intraventricular procedure (e.g. endoscopic biopsy) in addition to the initial first-time permanent procedure for the treatment of hydrocephalus.
