Visualase® for Epilepsy and Metastatic Tumors

Visualase® is an advanced, minimally invasive MRI-guided laser ablation technology that delivers high energy to a target area to destroy unwanted tissue. The use of the MRI enhances accuracy.

Advantages of Visualase Laser Ablation Technology at Willis-Knighton:

  • Most procedures are completed in less time as compared to open procedures
  • Most patients have little or no hair removed
  • Minimal sutures required, typically a one-stitch suture
  • Most patients are discharged after a shorter stay as compared to open procedures
  • Reduced scarring compared to open procedures
  • Performed in a sterile environment in the region’s only interventional MRI suite 

Visualase at Willis-Knighton is offered for patients with seizures and brain tumors:

  • Epilepsy due to mesial temporal sclerosis, not well-medically controlled or patient having medicine side effects
  • Epilepsy due to focal cortical dysplasia, not well-medically controlled or patient having medicine side effects
  • Epilepsy due to tumor, not well-medically controlled or patient having medicine side effects
  • Metastatic tumors, particularly in patients with one or two lesions who may have medical difficulty tolerating craniotomy or simply do not want open brain surgery for whatever reason
  • Primary or metastatic tumors that have recurred despite surgery and/or radiation
  • Tumors of the mesial temporal lobe, brainstem, or other difficult to access areas

What happens during Visualase procedure at Willis-Knighton?

  • In a specialized interventional MRI suite, the surgeon guides a small flexible laser to the intended target area
  • With the MRI, the surgeon precisely monitors treatment with software to measure temperature changes
  • Laser light heats and destroys the target area. Temperature maps show the surgeon the tissue being destroyed, minimizing risk of potential damage to surrounding healthy tissue.
  • The laser applicator is removed and the small incision is closed with minimal sutures (typically one stitch).
