Accessibility Aqueductal stenosis is one of the known causes of hydrocephalus and the most common cause of congenital (present at birth) hydrocephalus. A prospective comparison of 81 patients treated with either third ventriculostomy or primary shunting revealed no difference in outcomes between the two groups (800 days median follow-up) or between those who sustained ventriculostomy failure and required later shunting (24). This requires careful imaging and other workup as described in the following paragraphs.
