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. A small flexible laser is guided to the target area. Using the MRI images, the surgeon precisely monitors treatment with software that monitors temperature changes. Laser light heats and destroys the target area with precision, thanks to the MRI images, minimizing risk of damage to healthy surrounding tissue. A small incision is closed with minimally sutures, typically just one stitch.

Patients with seizures and brain tumors who are eligible

  • 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

Advantages

  • Most procedures are completed in less time, compared to open procedures
  • Little or no hair removal
  • Minimal sutures required, typically a one-stitch suture
  • Shorter stay than with open procedures
  • Reduced scarring, compared to open procedures
  • Performed in a sterile environment in the region’s only interventional MRI suite
