Endoscopic Third Ventriculostomy with Choroid Plexus Cauterization

Also known as: ETV/CPC.

What is endoscopic third ventriculostomy with choroid plexus cauterization?

Normally, fluid is formed in the brain (cerebrospinal fluid-CSF) by the choroid plexus (contains blood vessels) in the spaces of the brain tissue (ventricles) and flows through a pathway around the brain and spinal cord. It is continuously being made and reabsorbed.
When the fluid cannot flow or is not absorbed properly, fluid builds up-this is called hydrocephalus. Endoscopic third ventriculostomy with choroid plexus cauterization is a surgical treatment option for hydrocephalus, or fluid on the brain.

What happens during the procedure?

Endoscopic third ventriculostomy and choroid plexus cauterization are performed during the same surgery. A hole is made in the skull, and an endoscope is used to make a hole in the bottom of a ventricle. This reestablishes a normal spinal fluid flow. Choroid plexus cauterization involves burning the tissue that produces spinal fluid so that it doesn’t produce as much.

Is any special preparation needed?

Endoscopic third ventriculostomy with choroid plexus cauterization is a fairly complex procedure. A number of imaging tests are required before a baby/child will undergo the surgery.

What are the risk factors?

Cerebrospinal fluid pathway closure (20%-50%), infections, and fever are all potentially severe complications. Other complications include short-term memory loss and endocrine abnormalities.
