Background: Corpus callosotomy for medically intractable epilepsy is an effective ablative procedure traditionally achieved using either standard open craniotomy or with less-invasive approaches. Advances in robotic-assisted stereotactic guidance for neurosurgery can be applied for LITT for corpus callosotomy.
Clinical Presentations: Two patients were included in this study. One was a 25-year-old female patient with extensive bi-hemispheric malformations of cortical development and medically refractory epilepsy, and the other was an 18-year-old male with medically refractory epilepsy and atonic seizures, who underwent a complete corpus callosotomy using robotic-assisted stereotactic guidance for LITT.
Results: Both patients underwent successful intended corpus callosotomy with volumetric analysis demonstrating a length disconnection of 74% and a volume disconnection of 55% for patient 1 and a length disconnection of 83% and a volume disconnection of 33% for patient 2. Postoperatively, both patients had clinical reductions in seizure.
Conclusion: Our experience demonstrates that robotic guidance systems can safely and effectively be adapted for minimally invasive LITT corpus callosotomy.

Outcomes following resective and disconnective strategies in the treatment of epileptic spasms: a systematic review of the literature and individual patient data meta-analysis.

Epileptic spasms (ES) are a unique seizure type typically presenting in the form of infantile epileptic spasms syndrome (IESS) with characteristic hypsarrhythmia on scalp EEG and a preponderance with developmental delay or regression. While pharmacotherapy is the mainstay of treatment, surgical options, including disconnective or resective procedures, are increasingly recognized as viable therapeutic options for recurrent or persistent ES. However, limited data on safety, effectiveness, and prognostic factors hinder informed decision-making regarding surgery indications, timing, and intervention type.

Heterozygous pathogenic variants in MBD5 (MIM*611472) and CCM2 (MIM*607929) cause autosomal dominant intellectual developmental disorder 1 (MIM#156200) and cerebral cavernous malformations-2 (MIM#603284), respectively. Both conditions may present with seizures, epilepsy, and status epilepticus. However, super-refractory status epilepticus, defined as seizures lasting more than 24 h, has not been described in either condition.

Objective: To confirm the incidence of subcutaneous effusion secondary to cerebrospinal fluid leakage after craniotomy, analyze the risk factors for cerebrospinal fluid leakage leading to subcutaneous effusion, summarize the underlying causes of its occurrence and explore the corresponding treatment strategies.
Methods: A retrospective analysis was conducted on 757 patients who underwent craniotomy at our hospital from January to December 2023. The authors documented the sex, age, surgical characteristics, and history of chronic diseases for all patients, including those who developed subcutaneous effusion secondary to cerebrospinal fluid leakage.
Promising therapeutic strategies for Lennox-Gastaut syndrome: what's new?

Introduction: The seizures in Lennox-Gastaut syndrome are typically resistant to treatment. Seven antiseizure medications (ASMs) in the US (six in the UK/EU) are licensed for the treatment of seizures in LGS: lamotrigine, topiramate, rufinamide, clobazam, felbamate (not licensed in the UK/EU), cannabidiol and fenfluramine. Other options include neurostimulation, corpus callosotomy and dietary therapies, principally the ketogenic diet and its variants.
View Article and Find Full Text PDFLennox-Gastaut syndrome (LGS) is a severe developmental and epileptic encephalopathy (DEE) characterized by multiple types of drug-resistant seizures (which must include tonic seizures) with classical onset before 8 years (although some cases with later onset have also been described), abnormal electroencephalographic features, and cognitive and behavioral impairments. Management and treatment of LGS are challenging, due to associated comorbidities and the treatment resistance of seizures. A panel of five epileptologists reconvened to provide updated guidance and treatment algorithms for LGS, incorporating recent advancements in antiseizure medications (ASMs) and understanding of DEEs.
