“…Mem brane excision is still proposed for patients with arach noid cysts, although our experience would indicate that these patients do well with the insertion of a cystoperito neal shunt. In the D W C there may also be a role for cyst fenestration in those patients who have undergone re peated shunt revisions and in whom further shunting pro cedures may carry a significant risk [31]. Our patients were treated with either cystoperitoneal, ventriculoperi toneal, or a combination of shunts.…”

Fifty children with developmental retrocerebellar cysts of the posterior fossa, treated over an 11-year period, were assessed. The cysts were classified according to a morphological classification based on axial computerized tomography scans in order to assess the usefulness of this classification with regard to treatment and outcome. There were 35 patients with the Dandy-Walker complex and 15 patients with posterior fossa cysts. All surgically treated patients had cerebrospinal fluid shunting as the only form of treatment. Cystoperitoneal shunts were the treatment of choice. Although the morphological classification has relevance with regard to the embryological development of the cyst, it does not influence the selection of treatment nor the surgical outcome following shunt insertion.

“…In patients who experience frequent shunt malfunctions, however, this procedure may be considered an alternative to shunt placement, 1 and it has also been found to be beneficial in older children. Excision of the obstructing membrane, once advocated, is currently not considered the initial procedure of choice due to its associated risks of morbidity and mortality.…”

“…Others feel that the optimal surgical management of these patients is not so clear [32]. Osaka et al [33] recently reported the successful treatment of a patient with a 'disproportionately large, communicating fourth ventricle' following suboccipital craniotomy and excision of a membranous obstruction of Magendie's foramen.…”

Avoiding Complicated Shunt Systems by Open Fenestration of Symptomatic Fourth Ventricular Cysts Associated with Hydrocephalus

Optimal treatment of the hydrocephalic patient with symptomatic Dandy-Walker malformation or trapped fourth ventricle remains controversial. We describe 6 patients with symptomatic Dandy-Walker malformation or trapped fourth ventricle and hydrocephalus that were treated with an aggressive cyst fenestration. Four of the 6 patients had previously undergone five or more failed shunt procedures. There were no complications associated with surgery, and 5 of the 6 patients (83%) have remained asymptomatic with respect to their posterior fossa cysts. One patient has required subsequent fourth ventricular shunt placement. Median follow-up was 26 months (range 12–66 months). We suggest that suboccipital craniectomy and open fenestration is a valid treatment option in hydrocephalic patients with symptomatic Dandy-Walker malformation or trapped fourth ventricle. Although the associated lateral ventriculomegaly will probably still require a ventriculoperitoneal shunt, the absence of a cystoperitoneal shunt system seems to minimize the incidence of complications and reoperation.
