Abstract

Objective: This article describes a method of performing an intracerebral tumor resection utilizing a novel dilator attachment with a system designed for minimally invasive spinal surgery.

Methods: A novel dilator was designed and utilized in conjunction with a retractor system originally designed for minimally invasive spine surgery. Tumor resection was then performed utilizing a method less invasive than a typical cortisectomy but allowing more freedom than could be accomplished with an endoscope.

Results: Two patients underwent a standard craniotomy followed by tumor resection using the novel dilator with the Pipeline Minimally Invasive Retractor System® (DePuy Spine, Raynham, MA). The dilator was introduced into the tumor cavity followed by sequential insertion of the working ports until a working port of 20 mm had been inserted. Both patients had adequate resection of their tumors with minimal neurological deficit.

Conclusion: Tumor resection can safely be accomplished using a minimally invasive spine retractor system with a novel dilator adapted for the system. This reduces the size of the cortisectomy and therefore reduces the risk of post-operative neurological damage while still allowing ample room for adequate tumor resection.
