Technical Report: Durable efficacy of an endoscope-assisted syringo-panventriculoatrial shunt for concurrent hydrocephalus and syrinx

Abstract

The management of syringomyelia in association with hydrocephalus can be a challenging pathology to treat with durable results. We present a durable treatment of a patient with symptomatic, idiopathic hydrocephalus, Chiari type I malformation, and syringomyelia with an endoscope-assisted placement of a single syringo-panventricular multiperforated shunt catheter via a transfrontal transaqueductal approach with simultaneous endoscopic third ventriculostomy (ETV). We discuss the technical details required for this single-shunt approach to a complex pathology, and indications for appropriate use of this novel approach in experienced hands. The patient rapidly improved radiographically and symptomatically, with a functioning shunt twelve years postoperatively. For surgeons well-versed in endoscopic techniques, this approach can be safe, durable, and obviate the need for an otherwise complex shunting system with multiple catheters, or a more traditional invasive craniovertebral decompression, in a patient with idiopathic hydrocephalus and a syrinx.
