Clear Fluid Leakage After Brain Surgery: Understanding CSF Leaks

What Is CSF?

Cerebrospinal fluid (CSF) is a clear, colorless fluid filling brain ventricles and subarachnoid space. Produced by the choroid plexus, it circulates nutrients and removes waste.

Post-Surgical Leakage

CSF leaks are common after brain surgery because the dura mater (brain's outer layer) is opened. Leaks can also occur if the choroid plexus is damaged.

Clinical Course

• Usually not serious; resolves spontaneously in days/weeks.
• Can occasionally lead to infection or hydrocephalus (CSF buildup).

Action

If experiencing CSF leakage after brain surgery, seek medical evaluation and treatment promptly.
