Spot the correct spelling of a CSF-shunt procedure.

The correct answer is Ventriculoatrial.

Explanation:

A cerebrospinal fluid (CSF) shunt is a medical procedure used primarily to treat hydrocephalus, a condition characterized by an abnormal accumulation of CSF in the brain's ventricles.

The term is derived from two components:

1. Ventriculo-: Refers to the ventricles of the brain, where the excess fluid is drained from.

2. -atrial: Refers to the atrium of the heart, specifically the right atrium, where the fluid is drained into.

Combining these terms yields Ventriculoatrial (or Ventriculoatrial shunt, abbreviated as VA shunt). The other options contain spelling errors:

- "Ventriculoartial" transposes the 'r' and 't'.

- "Ventriculoatriall" has an unnecessary extra 'l'.

- "Ventriculoateriel" misspells the suffix "-atrial".
