title: Trapped fourth ventricle treated with shunt placement in the fourth ventricle by direct visualization with flexible neuroendoscope.
abstract: Shunt placement was the most common procedure used for ventricular dilatation, but in many neurosurgical centers it has been substituted by flexible neuroendoscope; however, none of them had solved the problem of the trapped and dilated fourth ventricle. The combination of the ventricle-peritoneal catheter placement in the center of the fourth ventricle by direct visualization with a flexible neuroendoscope using a single coronal burr-hole has solved this problem. Eleven patients with a trapped fourth ventricle, with previous third ventriculostomy and aqueductal plasty, were treated with this procedure; all patients were evaluated clinically and with computed tomography 8 to 24 months (mean, 18 months) later. Here, we describe the technical procedure.
