OBJECTIVE: To study the findings in radionuclide cisternography in patients with obstructive hydrocephalus following third ventriculostomy.
METHODS: Lumbar radionuclide cisternography was performed in 15 patients with obstructive hydro- cephalus before and after third ventriculostomy.
RESULTS: The postoperative cisternography identified radiopharmaceutical reflux into the lateral cerebral ventricles with delayed clearance for 24 h, similar to the findings by cisternography of communicating hydrocephalus.
CONCLUSION: The cause of ventricular radiopharmaceutical reflux is not yet understood, possibly in association with the reversal of normal cerebrospinal fluid flow though the fenestration on the third ventrical floor.
