Laser interstitial thermal therapy in neurosurgery: a single-surgeon experience of 313 patients.
Real-time MRI-guided focused laser interstitial thermal therapy (LITT) is a minimally invasive surgical treatment choice for challenging intracranial lesions that are either resistant to conventional therapies or located in deep or critical areas of the brain. However, existing studies on LITT within surgical neuro-oncology are relatively small and have limited follow-up periods. The authors aimed to present a comprehensive analysis of their experiences with LITT in surgical neuro-oncology, with the intent to provide a clearer understanding of the safety and efficacy of this procedure. ⋯ LITT stands as a secure and feasible ablative treatment choice for intracranial lesions, potentially suitable for specific patient cases otherwise not amenable to surgical intervention. These findings further corroborate the safety of the procedure and its favorable outcomes, underscoring its potential significance in clinical practice.

Stratified assessment of treatment approach for craniocervical junction arteriovenous fistulas: a multicenter cohort study and literature review.
Craniocervical junction arteriovenous fistulas (CCJ-AVFs) are complex vascular shunts that present a challenge for treatment. The aim of this study was to compare the clinical outcomes of microsurgery and endovascular embolization for CCJ-AVFs and to determine whether the treatment approach affected the obliteration rate and neurological improvement. ⋯ This study supports microsurgery as the best treatment modality for CCJ-AVFs, exhibiting the highest rates of complete obliteration. Conversely, embolization via the VA can result in a lower occlusion rate and less neurological improvement. In CCJ-AVFs with CA feeders, embolization via the CA can be a safe and effective alternative to microsurgery.

Thoracic neurogenic tumors usually present as benign nerve sheath tumors that can be resected via transthoracic or posterior approaches, depending on the anatomical location. Robot-assisted thoracic surgery (RATS) is increasingly being used for the transthoracic approach, but evidence is very limited. The authors initiated the current study to evaluate the efficacy and safety of RATS for thoracic neurogenic tumors. ⋯ RATS for thoracic neurogenic tumors is feasible and safe. Tumors at the thoracic apex are at high risk of neurological deficit and should be approached with care. Close interdisciplinary collaboration between neurosurgeons and thoracic surgeons is necessary for optimal patient selection and a good postoperative outcome.

Defining light transmission aggregometry cutoff values for clopidogrel and aspirin resistance in flow diversion treatment of intracranial aneurysms.
Concern about thromboembolic events after flow diversion (FD) warrants dual antiplatelet therapy for 3 to 6 months. Platelet function tests are routinely performed prior to the procedure to detect clopidogrel responsiveness, as resistance is associated with CYP2C19 gene polymorphisms. This study aimed to identify optimal cutoff values in light transmission aggregometry (LTA) for clopidogrel and aspirin as predictive indicators of thromboembolic complications. ⋯ This study analyzed the largest FD-treated cohort in which optimal LTA platelet function thresholds for clopidogrel were evaluated and is the first to assess LTA values for aspirin. The authors found that values ≥ 40% for clopidogrel and ≥ 13.5% for aspirin were optimal for predicting thromboembolic complications after FD in treating aneurysms.

Sex-dependent characteristics and outcomes after clipping of unruptured intracranial aneurysms: a multicenter propensity score-matched study.
Disparities in the epidemiology and growth rates of aneurysms between the sexes are known. However, little is known about sex-dependent outcomes after microsurgical clipping of unruptured intracranial aneurysms (UIAs). The aim of this study was to examine sex differences in characteristics and outcomes after microsurgical clipping of UIAs and to perform a propensity score-matched analysis using an international multicenter cohort. ⋯ Despite overall differences between male and female patients in demographics, comorbidities, and treated aneurysm location, sex did not relevantly affect surgical performance or perioperative complication rates.
