Endoscopic Third Ventriculostomy

An endoscopic third ventriculostomy (ETV) is a minimally invasive surgical procedure in which an opening is created in the floor of the third ventricle in the brain. This allows cerebrospinal fluid (CSF) to drain from the ventricles— helping restore the flow of CSF and reducing fluid pressure in the brain.

In this illustrated surgical sequence page layout, I broke down the procedure into 5 steps. For each step (aside from the initial incision), I illustrated both an endoscopic view as well as a midsagittal view to help provide anatomical orientation.
