Ultrasonography can be used in utero to diagnose aqueductal stenosis by showing dilation of the lateral and third ventricles.
2.
If the procedure does not successfully cure the aqueductal stenosis, a second surgery can be performed to enlarge the incision or implant a shunt.
3.
Signs of aqueductal stenosis other than those mentioned in Causes of stenosis include detection of an enlarged lateral and third ventricle in conjunction with a smaller fourth ventricle.
4.
Patients under the age of two, diagnosed with aqueductal stenosis without a history of preterm birth or other associated brain anomalies are being included ( International Infant Hydrocephalus Study ).
5.
An alternative treatment for obstructive hydrocephalus in selected patients is the endoscopic third ventriculostomy ( ETV ), whereby a surgically created opening in the floor of the third ventricle allows the CSF to flow directly to the basal cisterns, thereby shortcutting any obstruction, as in aqueductal stenosis.
