Abstract

Background

Trapped fourth ventricle (TFV) is a rare and difficult to treat condition. Most patients have a past inciting event (infection, IVH, trauma) and history of prior CSF diversion. The symptoms are due to the mass effect on brainstem and cerebellum. Rarely, TFV can also be associated with syrinx formation due to a dissociated craniospinal CSF flow near the fourth ventricle outlets. We present our experience and outcomes of open posterior fenestration in 11 cases, along with an overview of the surgical management of TFV.

Methods

Between 2011 and 2018, 11 patients of TFV were operated by the posterior approach fenestration of the fourth ventricle outlets and arachnoid dissection. The clinical and radiological findings of the patients were retrieved from the hospital database. The surgical technique is described in detail. The patients’ neurological status and imaging findings in the follow-up were recorded and compared.

Results

The average age of the patients was 23.55 years. The most common presenting symptoms were headache (9/11) and gait imbalance (7), with TB meningitis being the commonest etiology. Ten patients had a history of prior CSF diversion with two presenting with shunt malfunction. Mean follow-up duration was 33.33 months. The improvement in neurological status was observed in 9/11 patients, 2 remained status quo. On follow-up imaging, 8/11 (72.72%) patients had a decrease in the size of TFV while syrinx improved in 3/5 (60%).

Conclusion

Multiple surgical approaches have been described for TFV. Endoscopic fourth ventriculostomy with aqueductoplasty is gaining popularity in the past two decades. However, an open posterior fenestration of the midline fourth ventricle outlet (magendieplasty) along with sharp arachnoid dissection (adhesiolysis) along the cerebello-medullary cisterns and paracervical gutters is relatively simple and provides physiological fourth ventricular CSF outflow. This is especially useful in TFV with syrinx as the craniospinal CSF circulation is established.

Comments

The authors retrospectively review a single-centre case series of 11 patients who underwent surgery for symptomatic trapped fourth ventricle between 2010 and 2018. All underwent an open procedure involving a posterior fossa craniotomy and removal of the posterior arch of C1, with extensive adhesiolysis along the cerebellomedullary fissure, foramen of Magendie and upper cervical spine, and expansile duraplasty. Mean follow up was 33.3 months (all over six months) with clinical improvement in nine patients. The authors conclude that open surgery is an effective and safe method to treat a trapped fourth ventricle. While the surgical risk of an extensive open procedure in a chronically scarred posterior fossa and craniocervical junction may be considered to be higher than in image-guided shunting of the fourth ventricle, this technique allows some restoration of normal anatomy and CSF flow. This study offers further insight into a rare neurosurgical problem and is a valuable contribution to the existing literature.
