Where is the shunt typically inserted?

• A. Peritoneum
• B. Ventricles
• C. Subarachnoid space
• D. Scalp

Answer: (A)

The shunt is typically placed so that its distal end ends in the peritoneal cavity. In hydrocephalus seen with spina bifida, the common setup is a ventriculoperitoneal shunt, where CSF is drained from a ventricle through the shunt into the peritoneal cavity, where the peritoneum absorbs the fluid. The peritoneum offers a large absorptive surface, handles the ongoing growth of pediatric patients, and provides a reliable, well-established route. Other distal sites (like the pleural space or heart) exist but are less common, and the subarachnoid space isn’t used as the drainage termination. The proximal end is placed in the ventricle, which is where CSF collects and needs drainage.
