Largest neurosurgical social media group and its impact on communication and research.

BACKGROUND: The use of social media to communicate and disseminate knowledge has increased exponentially, especially in the field of neurosurgery. 'Neurosurgery cocktail' (NC) was developed by a group of young neurosurgeons as a means of sharing didactic materials and clinical experiences via social media. It connects 35.000 neurosurgeons worldwide on multiple platforms, primarily Facebook and Twitter. Given the rising utilization of social media in neurosurgery, the popularity of NC has also increased since its inception. In this study, the authors surveyed the social media analytics of NC for both Facebook and Twitter. Besides, we reviewed the literature on the use of social media in neurosurgery. METHODS: Facebook and Twitter metrics were extracted through each respective platform's analytics tools from December 2020 (earliest available date for data analysis) through January 2021. A literature search was conducted using PubMed (MEDLINE) and Scopus databases. RESULTS: On Facebook, as of January 2021, the group had a total of 25.590 members (87.6% male), most commonly (29%) between 35 and 44 years of age with over 100 countries were represented. As of January 2021, they had amassed 6457 followers on Twitter. During the last 28 d between December 2020 and January 2021, the account published 65 tweets that garnered a total of 196,900 impressions. Twelve articles were identified in our literature review on the use of social media within the neurosurgical community. CONCLUSIONS: NC is one of the most widely utilized neurosurgical social media resources available. Sharing knowledge has been broadened thanks to the recent social media evolution, and NC has become a leading player in disseminating neurosurgical knowledge.

Bypass cerebral de alto flujo con vena safena interna. Revisión del procedimiento y presentación de nuestra experiencia / High flow cerebral bypass with internal saphenous vein. Review of the procedure and presentation of our experience

INTRODUCCIÓN: el bypass cerebral de alto flujo (BPC-AF) es un procedimiento que se realiza cada vez con más frecuencia. En los últimos treinta años se publicaron más de 1000 procedimientos. El manejo de la técnica y la selección de pacientes para este tipo de tratamientos se han ido optimizando a lo largo del tiempo. OBJETIVO: actualizar las indicaciones quirúrgicas para los BPC-AF. Describir nuestra experiencia en 31 BPC-AF con vena safena. MATERIAL Y MÉTODOS: se realizó una búsqueda bibliográfica de los casos de BPC-AF publicados. Se analizó la evolución en las indicaciones para este procedimiento. Se reportó nuestra experiencia en este tipo de cirugía. RESULTADOS: desde la década del 80 se publicaron 4622 artículos sobre bypass, de los cuales 2612 fueron publicados desde el año 2000; 1056 de 2612 casos publicados correspondieron a alto flujo. El BPC-AF está indicado principalmente en a) aneurismas carotídeos gigantes, como primer tratamiento o por fracaso de cirugía endovascular; b) como cirugía de anticipación a la isquemia, cuando hay riesgo de oclusión de un vaso arterial importante, principalmente en el curso de patología tumoral o vascular de la base del cráneo; y c) en casos seleccionados de enfermedad cerebro-vascular que persiste sintomática a pesar del tratamiento médico. Nuestra experiencia incluyó 31 procedimientos realizados en 30 pacientes (16 de sexo femenino y 14 masculinos). La mayoría eran adultos, excepto 1 adolescente y 1 niño. CONCLUSIÓN: las indicaciones actuales del BPC-AF son prácticamente las mismas desde que fue realizado por primera vez, habiendo cambiado la aceptación que actualmente tiene esta técnica quirúrgica y su mayor uso en patología tumoral y vascular de la base del cráneo

INTRODUCTION: extracranial-Intracranial high-flow bypass (EC-IC-HFBP) is a surgical procedure performed with increasing frequency. Over the last thirty years, more than one thousand of this surgical procedures have been published. Technical management and patient selection for this kind of surgeries have been optimized over the time. OBJECTIVE: to update surgical indications for EC-IC-HFBP. To describe our experience in 31 EC-IC-HFBP using saphenous vein. MATERIAL AND METHODS: bibliographic search for EC-IC was performed. Evolution of surgical indications and criteria were analyzed. Our experience with this surgical procedure is reported. RESULTS: from 1980, 4622 articles about cerebral bypass were published, 2612 of them were published from the beginning of the new century; 1056/2612 corresponded to high-flow bypassses. EC-IC-HFBP are indicated a) in giant carotid aneurysms, as first treatment or by failure of endovascular surgery; b) anticipated surgery to prevent ischemia, when there is occlusion risk main arteries, mostly on tumoral or vascular pathology at the skull base; and c) in selected cases of cerebral-vascular diseases that persist with symptoms despite medical treatment. Our experience included 31 EC-IC-HFBP using saphenous vein carried out in 30 patients (16 females and 14 males). Most of procedures were performed on adults, excepting 1 teenager and 1 child. CONCLUSION: actual indications for EC-IC-HFBP are the same that those for the first procedures published;what changed is the general acceptance about this technique and its greater use in skull base tumoral and vascular pathology

El desarrollo e implementación de la resonancia magnética intraoperatoria en neurocirugía (remain) y su aplicación en 83 intervenciones en la Argentina / Development of REMAIN for neurosurgery and application in 83 operative intervention in Argentina

Objective: To show implementation and development of an operating room in which we operated 83 patients using intraoperative MRI (REMAIN). Method: We used a side-opening-magnet, 0.23 Tesla, installed in a surgical area specially designed with all the advances of the modern operating rooms. Results: A great variety of neuro-surgical procedures can be made with REMAIN controls. The obtained images are clear, without devices and with an excellent definition of the anatomical structures and the pathology, that allows the neurosurgeon to make more precise and safer interventions. Conclusions: The images of REMAIN in a surgical scope, make possible that injuries can be identified and located with absolute precision. It is particularly useful in determining with exactitude the tumor-like limits, optimizing the surgical approaches, obtaining complete extirpations of brain injuries and controlling the possible intraoperative complications.
