title: Endoscopic surgery for intracranial cerebrospinal fluid cyst malformations.
abstract: Endoscopic surgery represents a new and very useful modality of treatment for intracranial cysts. The authors review the cases of 19 patients with intracranial malformative CSF cysts (seven intraventricular, six paraventricular, and six arachnoid) who underwent endoscopic fenestration by using a burr-hole approach. The various endoscopic approaches and techniques of fenestration, according to the type and location of the cyst, and the causes of unsuccessful outcome are critically discussed. The authors recommend endoscopic fenestration as the treatment of choice for patients with para- and intraventricular cysts, in whom the procedure may help to avoid the microsurgical approach and shunt placement in nearly all patients. In patients with arachnoid cysts, the endoscopic procedure, although associated with a lower rate of successful outcome, may be performed as the primary procedure in most cases because it is a minimally invasive procedure; the traditional surgical treatment may be performed without additional risk in which endoscopic surgery has failed.
