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.
