Gliederung

Text

Objective: Magnetic resonance imaging guided laser ablation surgery (MRIGLAS) was demonstrated to be a viable tool especially for epilepsy and neurooncological patients. Apart from its variety of applications, different potential operative or technical nuances and options exist. In the present technical report, the authors firstly described the use and ability of a Riechert-Mundinger (RM) stereotactic frame combined with a novel drill guide kit for MRIGLAS.

Methods: A stereotactic frame-based setting was invented by combination of a conventional RM frame with a recently developed drill guide and centering screwing aid for bone anchors (Inomed) for application together with the Medtronic Visualase® system. The apparatus was initially used for MRIGLAS in a human head phantom and for stereotactic biopsy and consecutive MRIGLAS in an exemplarily brain tumor case thereafter.

Results: The neurosurgical use and potential of a RM stereotactic frame and an additional drill guide and screwing aid for MRIGLAS was assessed. Both MRIGLAS in a skull model and a stereotactic biopsy with subsequent MRIGLAS in a neurooncological patient could be easily and safely performed by the novel system. Duration of surgery was not prolonged when compared to alternative methods and no technical problems or perioperative clinical complications could be observed.

Conclusion: By implementation of a novel technique, both MRIGLAS in vitro in a phantom and in vivo in a patient was successfully performed. In our promising initial but limited preliminary experience, the combination of a RM stereotactic frame and an additional drill guide tool provides neurosurgeons with the opportunity to reliable confirm the diagnosis by a frame-based stereotactic biopsy and allows for safe and simple real-time MRIGLAS.
