Robot-assisted stereotactic laser ablation in medically intractable epilepsy: operative technique

Area of Science:

• Neurosurgery
• Minimally Invasive Procedures
• Robotic Surgery

Background:

• Stereotactic laser ablation is advantageous for treating brain pathologies compared to open surgery.
• Robot-assisted stereotactic laser ablation offers a potentially accurate, efficient, and minimally invasive approach for targeting brain lesions.

Observation:

• A 19-year-old female with refractory focal seizures underwent robot-assisted laser ablation.
• The Visualase laser catheter was guided by the ROSA robotic system to a periventricular heterotopic lesion.
• Magnetic resonance imaging (MRI) confirmed accurate catheter placement and lesion ablation.

Findings:

• The procedure demonstrated accurate skin entry and trajectory, with the applicator reaching the lesion boundary.
• Laser ablation took under 3 minutes, with the total procedure lasting approximately 90 minutes.
• Post-ablation MRI confirmed successful lesioning; the patient experienced no complications and was discharged the next day.

Implications:

• This combined technique (Visualase, ROSA, intraoperative MRI) offers a safe, effective, and minimally invasive method for treating brain lesions.
• The approach may be adaptable for future placement of multiple electrodes for various neurological conditions.
• This technology advances neurosurgical treatment options for patients with complex brain pathologies.
