Distinct brain network structure of mesial temporal lobe epilepsy compared to that of neocortical epilepsy: functional MRI study with surgically treated patients.
Mesial temporal lobe epilepsy (mTLE) and neocortical epilepsy (NE) have different anatomo-clinical characteristics. The authors hypothesized that this may be reflected in the different functional connectivity of the epileptogenic zone between mTLE and NE. The authors, therefore, examined preoperative resting-state functional connectivity MRI with regional global connectivity (rGC) analysis for surgically treated patients. The goal of this study was to detect the different functional networks associated with the epileptogenic zone between mTLE and NE. ⋯ The authors revealed a distinct brain network structure between mTLE and NE based on rGC analysis with resting-state functional MRI. The authors' unique functional connectivity analysis may be helpful for providing landmarks for lateralization or epileptogenic zones in mTLE and NE.

The value of a neurosurgeon: is neurosurgical compensation proportional to value added? A systematic review of the literature and an update on a changing healthcare economy.
Determining the value of a neurosurgeon is complex. Services provided by neurosurgeons have a range of interested parties-from a patient's singular health interest to a community catchment area rendering on-call emergency services. Such complexity makes it difficult to determine and define value. As healthcare reimbursement changes continue to transition further toward value-based/bundled payments, such determinations remain difficult and confusing. Given these factors, now more than ever before, neurosurgeons need to be active participants in the evolving discussions surrounding healthcare advocacy, value, and compensation in an ever-evolving and convoluted system. The objective of this study was to review and present current trends within the evolving landscape of healthcare economics and their impacts on the perceived value of neurosurgical services. ⋯ Medical compensation continues to evolve toward more value-driven methods. Value created as a neurosurgeon is complex, but it should not be underestimated as a key driver of hospital revenue, with up to $2.6 million created annually from neurosurgical hospital admissions. Further discussion is needed to elucidate alternative innovative payment strategies to ensure physicians remain active in the evolving structure of our healthcare system.

Implementation of high-definition fiber tractography for preoperative evaluation and surgical planning of brainstem cavernous malformation: long-term outcomes.
The aim of this study was to describe the role and long-term outcomes of high-definition fiber tractography (HDFT) in the surgical management of brainstem cavernomas. ⋯ HDFT provides critical anatomical information guiding an optimal surgical corridor and more importantly defining eloquent perilesional boundaries. In this preliminary experience, preoperative planning with HDFT appeared to decrease morbidity in patients who underwent microsurgical resection of their brainstem cavernoma.

Laser interstitial thermal therapy for cavernous malformations: a meta-analysis of individual patient-level data.
Several case series have investigated the use of laser interstitial thermal therapy (LITT) to treat cavernous malformations (CMs), for either seizure control or reduction of neurological symptoms and future hemorrhage risk. However, pooled outcomes are largely unknown. The authors aimed to quantify posttreatment seizure freedom, symptomatic progression or hemorrhage, perioperative complications, and imaging outcomes from the available literature. ⋯ LITT is a promising therapy for CMs with the goal of seizure control or prevention of symptomatic progression or hemorrhage. While there is a notable risk of immediate postablation neurological deficit, most were transient and nondisabling, and this risk must be weighed against that of continued observation or open resection. Considering the limited number of studies, small number of patients, and limited follow-up time available, additional experience and research with larger patient cohorts and longer-term follow-up will be necessary to validate these findings.
