Minimally invasive surgical approach for intractable seizure

Area of Science:

• Neurosurgery
• Epileptology
• Minimally Invasive Procedures

Background:

• Intractable seizures pose significant challenges for patients.
• Many patients with severe epilepsy are poor candidates for traditional resective surgery.
• Exploring less invasive surgical options is crucial for improving patient outcomes.

Purpose of the Study:

• To evaluate the efficacy and safety of minimally invasive surgical procedures for intractable epilepsy.
• To assess outcomes in a cohort of patients with complex seizure foci.
• To determine the feasibility of surgical intervention in patients with poor surgical candidacy.

Main Methods:

• Surgical procedures included multiple subpial transection, topectomy, and amygdalahippocampotomy.
• Twenty-four patients with intractable seizures underwent these minimally invasive procedures.
• Seizure foci locations varied across hemispheres and lobes, with some involving multiple lobes or the temporal lobe exclusively.

Main Results:

• Follow-up ranged up to 41 months (median 18 months).
• Excellent results were achieved in 10 patients (66%) and good results in 6 patients (38%), totaling 100% with positive outcomes.
• No permanent complications were reported, indicating a favorable safety profile.

Conclusions:

• Minimally invasive epilepsy surgery offers a promising treatment option for intractable seizures.
• These procedures demonstrate high efficacy and safety, even in patients with extensive or complex seizure foci.
• The study highlights the potential for improved seizure control in patients previously deemed unsuitable for surgery.
