INTRODUCTION: The emergence of high-resolution brain imaging technologies has enabled early identification Unruptured Intracranial Aneurysms (UIAs). UIAs can evolve into subarachnoid hemorrhage (SAH), and prophylaxis complications includes neurosurgical clipping endovascular treatment, yet the optimal treatment choice remains incompletely understood. METHODS: PubMed, Embase, Cochrane were searched for randomized clinical trials observational studies comparing with surgical management...

AbstractThis study was designed to the microvascular anatomy of basilar artery between superior cerebellar and vertebrobasilar junction (i.e. lower artery). Twenty unfixed brains were injected with silicone rubber solution studied a Zeiss OPMI microscope. The length this segment 28.1 + 1.35 mm its course straight in 9 (45%) brains, curved 7 (35%) tortuous 4 (20%). total number perforators found 20 340 an average 17 per brain. Of these, 118 (34.7%) median 222 ( 65.2%) lateral. Median branches...

As malformações congênitas constituem alterações de estrutura, função ou metabolismo presentes ao nascer, que resultam em anomalias físicas mentais, podendo não ser simples múltiplas e maior menor importância clínica. O objetivo é analisar a freqüência das extremidades maternidades da cidade Maceió. Realizou-se um estudo coorte transversal prospectivo 2500 recém-nascidos no período julho 2002 junho 2003, junto às Casa Maternal Santa Mônica, Hospital Memorial Arthur Ramos Misericórdia Foram...

The pterional craniotomy, described by Yasargil and Fox in 1975, constitutes the most traditional important surgical access vascular neurosurgery. Minimally invasive alternatives include minipterional (MP) lateral supraorbital (LSO) craniotomies, which avoid complications such as injury to frontal branch of facial nerve, temporal muscle dysfunction, depression craniotomy site, sinus opening, cosmetically unacceptable outcomes. We evaluated compared exposures provided MP LSO craniotomies...

Introduction: gliomas are brain and spinal cord tumors that originate in glial cells whose progression invades the adjacent tissue among them one of most challenging located cerebral lobe insula. These arteries supply noble structures their damage can cause sensory, motor language damage. Objective: To describe impact extent resection, overall survival functional results after surgery for insular gliomas, when these or not involved by lenticulostriate arteries. Methods: Integrative review on...

Abstract Objective This article is divided into three parts. In the second part of this review, authors focus on describing endolymphatic sac tumor and presenting illustrative cases. Methods A review previous studies, from 1957 to 2021, basic translational research using human animal (ES) tissue or cells, as well other reviews theme. Results The ES an inner ear structure, which responsible for homeostatic regulation, fluid volume control, immune response etc. One possible alterations ELST, a...

Abstract Objective To describe the microsurgical anatomy and physiology of endolymphatic sac (ES) that a neurosurgeon should know. Methods Review previous studies from 1927 to 2021, basic translational research using human animal ES tissue or cells, as well reviews about subject. The present article is divided into three parts. In this first part, we review ES. Results structure situated in inner ear, together with cochlea, vestibular system, other structures. Differently its adjacent...

Introduction: Medulloblastomas are the most common solid tumors of childhood and classified into 4 molecular subgroups: WNT, SHH, Group 3 4. Many studies seek to develop new chemotherapy drugs for medulloblastomas by identifying genes whose expression is targets drugs, such as membrane receptors associated with cell replication. Objective: To evaluate association CD114 mortality in patients medulloblastoma. Methods: Review carried out collecting information published on virtual platforms...

El conocimiento profundo anatomía microquirúrgica y abordajes quirúrgicos para el estos primera etapa aprendizaje un manejo ideal. Este artículo se divide en dos partes: parte presentará resultados relevantes meningiomaspetroclivales. En segunda parte, autores correlacionan esta con 30 casos operados por autor principal (GRI). Métodos: Se disecaron...

Abstract The learning curve reflects surgeons' experience in managing several patients with the same disease. In skull base surgery, professional's place on could be related to number of times procedure was performed. Where does begin? What amount training is necessary prior its application surgical settings? were results first few tumor surgeries performed by a surgeon who goes produce excellent results, and how reflected start their curve? only way for neurosurgeons improve from...

Abstract In this second part, the authors review and suggest a methodology for studies in skull base surgery training microsurgical laboratory, based on their experiences reflections. Not only are foundations acquisition of skills presented, but also what is needed to be an effective skullbase surgeon with good results. The present article reflects particular philosophy professor Evandro de Oliveira serves neurosurgical community new state-of-the-art laboratory hands-on courses Brazil, at...
