Vagus nerve stimulation in pediatric patients with drug-resistant epilepsy: a step-by-step video.

Vagus nerve stimulation (VNS) is a neuromodulatory treatment involving chronic intermittent electrical stimulation of the left vagus nerve, administered through a programmable pulse generator implanted subcutaneously in the chest. This generator connects to a bipolar lead, with electrodes wrapped around the vagus nerve in the neck. Primarily used as an adjunct therapy for patients with refractory epilepsy who cannot undergo or have not benefitted from resective surgery, VNS is generally well tolerated with few severe side effects.

How I do it: operative nuances of the Encephalo-Duro-Mio-Synangiosis (EDMS) technique for pediatric moyamoya disease and syndrome.

Background: Moyamoya disease, a progressive occlusive arteriopathy mainly affecting the supraclinoid internal carotid artery, leads to abnormal "Moyamoya vessels" and ischemic events in children due to decreased cerebral blood flow. Surgery, especially indirect revascularization, is suggested for pediatric Moyamoya cases.

Method: We present the Encephalo-Duro-Mio-Synangiosis (EDMS) technique, illustrated with figures and videos, based on 14 years' experience performing 71 surgeries by the senior author (SGJ) and the Moyamoya Interdisciplinary Workteam at "Prof.

Surgical Anatomy and Technique of Peri-Insular Hemispherotomy in Pediatric Epilepsy.

Background And Objectives: Hemispherotomy is a highly complex procedure that demands a steep learning curve. An incomplete brain disconnection often results in failure of seizure control. The purpose of this article was to present a step-by-step guide to the surgical anatomy of this procedure.

Neurosurgical simulation models developed in Latin America and the Caribbean: a scoping review.

Simulation training is an educational tool that provides technical and cognitive proficiency in a risk-free environment. Several models have recently been presented in Latin America and the Caribbean (LAC). However, many of them were presented in non-indexed literature and not included in international reviews.

Results of training with a low-cost simulation model for endoscope-assisted scaphocephaly repair.

Objective: Endoscope-assisted repair of sagittal craniosynostosis is an effective technique that requires a learning curve. Surgical simulation models can be applied to acquire the necessary skills for this procedure. Several models with a wide range of costs have been described for training in this technique.

A Low-Cost Simulation Model for Endoscopic-Assisted Sagittal Craniosynostosis Repair.

Objective: The objective is to introduce a low-cost simulation model for endoscopic-assisted sagittal craniosynostosis repair in which bleedings can be simulated and to present the initial experience using the model as a learning tool.

Methods: A 3-dimensional synthetic skull was printed using polylactic acid. The brain, dura mater, sagittal sinus, and skin were constructed using low-cost materials.

[Coma due to syndrome of the trephined].

The syndrome of the trephined or craniectomized is commonly referred as neurological manifestations associated to skin flap depression and reversible after craneoplasty, which allows its differentiation from post-traumatic syndrome. We present the case of a male patient, 36 years old, with history of decompressive craniectomy. He evolved with sudden neurological worsening associated to syndrome of the trephined and recovery after craneoplasty.
