These illustrations were created for the article Endoscopic aqueductal stenting in the management of pediatric hydrocephalus in the Journal of Neurosurgery.

The mesencephalic aqueduct, or Sylvius aqueduct, normally ensures communication between the third and fourth ventricles. In the event of aqueduct stenosis, cerebrospinal fluid accumulates in the upper ventricles, causing hydrocephalus. To drain this fluid, two methods are compared here: endoscopic ventriculostomy, involving perforation of the third ventricle floor; and insertion of a stent into the aqueduct to restore its original function.
