Bilateral Torkildsen Procedure

T HE operative procedure ventriculocisternostomy, first proposed by Torkildsen, 2 has become an accepted and effective method in relieving a non-communicating hydrocephalus. In a previous communication, presented before this group in 1947, our ~ accumulated experiences were set forth in utilizing this procedure. Since this report the operation has been performed in an additional 16 cases. I t is the purpose of this discussion to report 3 instances in which a double drainage of the lateral ventricles seemed preferable to a single ventriculocisternal communication. In addition, attention is focused on the possible utilization of this procedure in dealing with certain craniopharyngiomas and other massive growths that completely usurp or distort the mid-supratentorial ventricle.
