ABSTRACT
Chiari malformation type III is a rare congenital anomaly. It consists of the posterior fossa contents herniation through an occipital or high cervical encephalocele sac. Although it has traditionally been associated with a high mortality rate, the absence of certain poor prognostic factors and appropriate medical and surgical treatment allow these children to survive and have a remarkable initial functional improvement. Surgical goals are defect repair, preservation of viable brain tissue, adequate skin coverage and hydrocephalus management. Despite all of this, the tendency of these newborns is to maintain a significant disability and if they present poor prognostic criteria, they usually demise within a short period of time. We report the case of a newborn with Chiari malformation type III diagnosed during pregnancy. After characterizing the anomaly with a postnatal MRI, the encephalocele was excised and multi-layer closure was performed. The patient progressively developed hydrocephalus during the postoperative period and required ventriculoperitoneal shunt placement. After an initial uneventful course, our patient suffered several episodes of respiratory disturbances. The child became ventilator dependent and palliative care was established in agreement with the parents after ruling out shunt malfunction.
ABSTRACT
BACKGROUND AND OBJECTIVES: The prevalence of unruptured intracranial aneurysms is 1-3%. The annual rupture rate increases in patients with multiple aneurysms that presented a previous hemorrhage from another aneurysm. OBJECTIVES: To evaluate outcomes of clipping unruptured aneurysms, comparing patients with single or multiple aneurysms clipped, describe the complications related to surgery and to identify risk factors predicting an unfavorable outcome. MATERIALS AND METHODS: Retrospective study including patients who underwent clipping of unruptured aneurysms between 2020-2023 at our center. Occlusion rate, complications, and functional outcome were analyzed. Risk factors for poor prognosis are identified using univariate model. RESULTS: 82 patients with 114 aneurysms were treated with microsurgery. Multiple aneurysms were clipped in 22 patients. A mini-open approach was used in 86,5% of cases. Complete occlusion in angio3D was found in 78.6% of clipped aneurysms. Complication rate was 12.2%, including asymptomatic cases. Mortality was 0%. The probability of 1 point mRS worsening was 7.3% and 2 or more points was 1.2%, with a good functional outcome in 98.9%. Clipping multiple aneurysms, miniopen approaches, or surgery in patients with previous subarachnoid hemorrhage did not increase the risk of complications. Posterior circulation aneurysms surgery increased the risk of ischemia. CONCLUSIONS: The management for unruptured intracranial aneurysms should be multimodal and based on clinical and radiological outcomes. Microsurgery is a valid and safe technique, with 0% mortality and bleeding rates and 1,2% rate of severe morbidity in our series.
ABSTRACT
INTRODUCTION: Subarachnoid haemorrhage (SAH) is one of the most frequent neurosurgical emergencies, most of them due to intracranial aneurysm rupture. Hydrocephalus is a prevalent complication with a high rate of complications. The aims of this study are to identify predictors of shunt-dependent hydrocephalus following aneurysmal SAH and to quantify the complications arising from ventriculoperitoneal shunts. METHODS: This study is about an observational retrospective analytic study of the patients with spontaneous SAH admitted to Miguel Servet Universitary Hospital between 2017 and 2022. Patients' clinical and radiological characteristics, type of treatment, diagnoses and treatment of hydrocephalus, complications of ventriculoperitoneal shunts and mortality are some of the data achieved in this study. A descriptive study of these variables has been done and, subsequently, the most relevant variables have been statistically analysed to identify patients with increasing risk of shunting for hydrocephalus. This study was authorized by the Ethics Committee prior to its elaboration. RESULTS: A total of 359 patients with spontaneous SAH were admitted to Miguel Servet Universitary Hospital between 2017 and 2022, with an intrahospitalary death rate of 25.3%. 66.3% of the total of patients with SAH were due to intracranial aneurysm rupture (nâ¯=â¯238). 45.3% of the patients with aneurysmal SAH required an external ventricular drain (EVD) to treat acute hydrocephalus. 11.7% (nâ¯=â¯28) developed a shunt-dependent hydrocephalus. Statistical significance was found between shunt-dependent hydrocephalus and the following: high score in modified Fisher scale and placement of EVD. The mean interval from EVD to ventriculoperitoneal shunt placement was 26.1 days. The mean rate of reoperation of patients after shunt was 17.7%, mostly due to infection. CONCLUSIONS: The most significant risk factor for shunt-dependent hydrocephalus after aneurysmal SAH was high Fisher grade and previous need of EVD. Shunt infections is the main cause of shunt reoperation. Early shunt placement in selected patients might reduce the rate of infectious complications.

We present a unique clinical case of venous congestive encephalopathy in the context of a cerebral arteriovenous fistula with clinical worsening secondary to valvular overdrainage. ICP monitoring, the different pressure settings of the programable CSF shunt and the detailed clinical description that is carried out offer us enough data to understand that this case provides important pathophysiological knowledge to a little-known disease.

OBJECTIVES: The large number of infected patients requiring mechanical ventilation has led to the postponement of scheduled neurosurgical procedures during the first wave of the COVID-19 pandemic. The aims of this study were to investigate the factors that influence the decision to postpone scheduled neurosurgical procedures and to evaluate the effect of the restriction in scheduled surgery adopted to deal with the first outbreak of the COVID-19 pandemic in Spain on the outcome of patients awaiting surgery. DESIGN: This was an observational retrospective study. SETTINGS: A tertiary-level multicentre study of neurosurgery activity between 1 March and 30 June 2020. PARTICIPANTS: A total of 680 patients awaiting any scheduled neurosurgical procedure were enrolled. 470 patients (69.1%) were awaiting surgery because of spine degenerative disease, 86 patients (12.6%) due to functional disorders, 58 patients (8.5%) due to brain or spine tumours, 25 patients (3.7%) due to cerebrospinal fluid (CSF) disorders and 17 patients (2.5%) due to cerebrovascular disease. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was mortality due to any reason and any deterioration of the specific neurosurgical condition. Second, we analysed the rate of confirmed SARS-CoV-2 infection. RESULTS: More than one-quarter of patients experienced clinical or radiological deterioration. The rate of worsening was higher among patients with functional (39.5%) or CSF disorders (40%). Two patients died (0.4%) during the waiting period, both because of a concurrent disease. We performed a multivariate logistic regression analysis to determine independent covariates associated with maintaining the surgical indication. We found that community SARS-CoV-2 incidence (OR=1.011, p<0.001), degenerative spine (OR=0.296, p=0.027) and expedited indications (OR=6.095, p<0.001) were independent factors for being operated on during the pandemic. CONCLUSIONS: Patients awaiting neurosurgery experienced significant collateral damage even when they were considered for scheduled procedures.

INTRODUCTION: Acute negative-pressure hydrocephalus is an uncommon, underrecognized patology with a high morbidity and mortality. We propose an algorithm to facilitate the management of these patients, promoting the early diagnosis and the use of endoscopic third ventriculostomy as initial therapeutic option. METHODS: We performed an observational retrospective study in which patients diagnosed with acute negative-pressure hydrocephalus were included. Patient age and symptoms, primary etiology of hydrocephalus, previous shunt, infection and surgical procedures, time from clinical deterioration to endoscopic procedure, definitive treatment and patient outcomes were recorded. Our management algortihm is exposed and justified. RESULTS: We identified five patients with diagnosis of acute negative-pressure hydrcephalus. In four of them the management algorithm was applied and early diagnosis and endoscopic ventriculostomy were performed. We observed complete succes of the endoscopic procedure in two patients (50%); the other two required permanent shunt, nevertheless resolution of the low-pressure state was achieved. One patient died after systemic infection (20%), 80% of the patients experienced good outcome. CONCLUSIONS: The early identification of a negative-pressure hydrocephalic state is essential to reduce complications. Application of a specific management algortihm and early endoscopic third ventriculostomy could be advantageous to achieve better outcomes.

Posttraumatic syringomyelia (PTS) is a well-reported phenomenon that usually takes place in the long-term course of patients following spinal cord injury. Different surgical procedures have been described: spinal cordectomy is usually a last option technique, but might be an excellent choice in patients with severe spinal cord injuries. We present a young patient with complete spinal cord injury after spine trauma, who developed posttraumatic syringomyelia with progressive motor deterioration twelve years after fixation. We performed a novel surgical technique (myelopexy) with excellent resolution of syringomyelia, sparing the negative implications of complete cord transection. Some artistic illustrations made by one of the corresponding authors are included, to better understanding of operative details.

OBJECTIVE: To assess the effect of the first wave of the SARS-CoV-2 pandemic on the outcome of neurosurgical patients in Spain. SETTINGS: The initial flood of COVID-19 patients overwhelmed an unprepared healthcare system. Different measures were taken to deal with this overburden. The effect of these measures on neurosurgical patients, as well as the effect of COVID-19 itself, has not been thoroughly studied. PARTICIPANTS: This was a multicentre, nationwide, observational retrospective study of patients who underwent any neurosurgical operation from March to July 2020. INTERVENTIONS: An exploratory factorial analysis was performed to select the most relevant variables of the sample. PRIMARY AND SECONDARY OUTCOME MEASURES: Univariate and multivariate analyses were performed to identify independent predictors of mortality and postoperative SARS-CoV-2 infection. RESULTS: Sixteen hospitals registered 1677 operated patients. The overall mortality was 6.4%, and 2.9% (44 patients) suffered a perioperative SARS-CoV-2 infection. Of those infections, 24 were diagnosed postoperatively. Age (OR 1.05), perioperative SARS-CoV-2 infection (OR 4.7), community COVID-19 incidence (cases/105 people/week) (OR 1.006), postoperative neurological worsening (OR 5.9), postoperative need for airway support (OR 5.38), ASA grade ≥3 (OR 2.5) and preoperative GCS 3-8 (OR 2.82) were independently associated with mortality. For SARS-CoV-2 postoperative infection, screening swab test <72 hours preoperatively (OR 0.76), community COVID-19 incidence (cases/105 people/week) (OR 1.011), preoperative cognitive impairment (OR 2.784), postoperative sepsis (OR 3.807) and an absence of postoperative complications (OR 0.188) were independently associated. CONCLUSIONS: Perioperative SARS-CoV-2 infection in neurosurgical patients was associated with an increase in mortality by almost fivefold. Community COVID-19 incidence (cases/105 people/week) was a statistically independent predictor of mortality. TRIAL REGISTRATION NUMBER: CEIM 20/217.

The pineal region is a complex anatomical location with multiple surrounding important neurovascular structures.1,2 Several approaches to this region have been described, including posterior interhemispheric, transchoroidal, infratentorial supracerebellar, supracerebellar and infracerebellar trans-sinus, and their modifications. Neuroendoscopy and endoscope-assisted surgery have been widely applied to aid resection of pineal region lesions.3-5 A 40-year-old man presented with tonic-clonic seizures and bilateral papillary edema on fundus examination. Computed tomography showed a midline lesion at the level of the quadrigeminal cistern with mass effect on the aqueduct of Sylvius and posterior wall of the third ventricle, triggering obstructive triventricular hydrocephalus. As a first intervention, a third ventriculostomy was attempted unsuccessfully owing to unfavorable third ventricle floor anatomy. This approach was used to obtain a biopsy specimen, which showed an epidermoid cyst. Ventriculoscopy showed a communication of the pineal recess and quadrigeminal cistern owing to tumor invasion. An external ventricular drain was placed to control the hydrocephalus until complete resection was performed (Video 1). Several days later, tumor resection was carried out via the median supracerebellar infratentorial approach with the patient in semisitting position. After near-total resection under microscope, the third ventricle and both lateral recesses were explored with the endoscope. A small tumor remnant (visible only with endoscope) was identified and removed. This step was essential to achieve complete resection, confirmed by magnetic resonance imaging. The patient was discharged 6 days later without complications. During follow-up, the patient remains asymptomatic. The combination of microneurosurgery, neuroendoscopy, and endoscope-assisted surgery improves management of pineal region lesions and facilitates complete resection.

BACKGROUND: One of the most feared and dangerous scenarios that can appear during an endoscopic endonasal surgery (EES) is the iatrogenic injury of the internal carotid artery (ICA). Several methods, along with a variety of outcomes, have been described to deal with this complication. To the authors' knowledge, this is the first report on the use of a Yasargil-type aneurysm clip to solve an ICA injury, preserving the artery's patency and having a long-term follow-up. The authors discuss the advantages and disadvantages of other vessel preservation techniques compared with clipping. OBSERVATIONS: A visually impaired 56-year-old woman was diagnosed with a giant nonfunctional pituitary tumor that invaded the sphenoidal sinus, anterior and posterior ethmoidal cells, and both cavernous sinuses, with suprasellar extension and optochiasmatic compression. The patient underwent EES, and during the final resection phase her left ICA was injured, with massive hemorrhage. LESSONS: ICA injury during endoscopic skull base surgery carries high mortality and morbidity; it is essential to maintain carotid flow when possible to avoid short-term and long-term consequences. There are several techniques depicted in the literature to deal with this situation. The authors report the use of a Yasargil mini-clip to deal with the injury for a positive outcome: primary hemostasis, vessel preservation, and no postoperative complications.
ABSTRACT
PURPOSE: The fusion of the upper cervical spine in children is demanding due to its reduced size, its anatomical complexity, or a severe pathology of the cranio-cervical junction. In some pediatric patients with today's more popular C1-C2 or, occipito-C2 techniques, it is impossible, or very risky to perform a short upper cervical fixation. METHODS: We present the utility and good results of ipsilateral laminar C2 screws insertion technique in two pediatric cases with low C2 laminar profile. Case 1: a 5-year-old child with a C1-C2 unstable subluxation, and a condylar assimilation of C1, where we performed an occipito-C2 fixation using an occipital plate and this modified translaminar C2 screw technique. Case 2: a 8-year-old Down syndrome boy who suffered an unstable subluxation of C1-C2 upon whom we performed a C1-C2 screw fixation using the same technique. RESULTS: Both cases have been followed up over a period of 7 and 2 years respectively, with good clinical results. CONCLUSIONS: We describe the technique and the feasibility of the ipsilateral insertion of translaminar C2 screws in children with low laminar profiles, as a good alternative to other techniques when the anatomy of the C2 does not permit its use or make them very risky.

ABSTRACT
OBJETIVO: El envejecimiento de la población es una realidad objetivable para la que los sistemas de salud no están adaptados. La Organización Mundial de la Salud ya ha avisado de la importancia de la implementación de medidas específicas, que abarcan desde la formación pregrado hasta la instauración de un número adecuado de geriatras, para seguimiento de los pacientes mayores. Nos proponemos analizar si la intervención del geriatra en el seguimiento del paciente neuroquirúrgico aporta beneficios. MATERIAL Y MÉTODOS: Se lleva a cabo un estudio descriptivo de cohortes, parcialmente prospectivo, analizando a todos los pacientes mayores de 75 años ingresados a cargo del servicio de Neurocirugía y que fueron atendidos en seguimiento compartido por Geriatría desde junio de 2015 hasta febrero de 2017. Se comparan con los pacientes mayores de 75 años ingresados en Neurocirugía entre octubre de 2013 y mayo de 2015 (periodo equivalente) en el que los geriatras solo intervinieron como unidad de valoración sociosanitaria a la hora de derivar al paciente a otro nivel asistencial. Se analizaron edad media, sexo, entidad neuroquirúrgica que motivó el ingreso, estancia media, complicaciones infecciosas, referencia escrita de síndrome confusional, ingreso en unidad de cuidados intensivos, necesidad de interconsulta con otros servicios, reintervención quirúrgica, mortalidad durante el ingreso, derivación a recurso sociosanitario, reingreso al mes y mortalidad al año. RESULTADOS: Se comparó a un total de 173 pacientes en seguimiento conjunto con 189 del periodo previo. Ambas cohortes presentaron características demográficas similares. Durante el periodo de manejo conjunto se redujeron la estancia media hospitalaria, la incidencia de complicaciones infecciosas, la necesidad de ingreso urgente en unidad de cuidados intensivos, la necesidad de interconsulta con otras especialidades, la tasa de readmisión a los 30 días y la mortalidad anual, todas ellas con diferencias estadísticamente significativas. CONCLUSIONES: El seguimiento compartido entre Neurocirugía y Geriatría disminuye la estancia media, la morbilidad, la necesidad de interconsulta con otras especialidades, el reingreso precoz y la mortalidad al año en los mayores de 75 años. Además, prioriza una atención centrada en la persona, disminuye costes y racionaliza los recursos
OBJECTIVE: Population ageing is a reality for which national health systems are not adapted. The World Health Organisation has already raised awareness about the implementation of specific measures, from undergraduate training to dedicated elderly care units, to tackle this situation. In this article, the aim is to analyse the potential benefits of geriatric monitoring on elderly neurosurgical patients. MATERIAL AND METHODS: A descriptive analysis was performed in this medical centre, comparing the information collected from elderly patients (over 75 years of age) admitted into the neurosurgical department during 2periods: June 2015 to February 2017, in which a shared geriatric monitoring was implemented, and between October 2013 and May 2015, equivalent period, in which only the geriatrician performed the evaluation of the patients' general condition, before referring them to other social-healthcare units. A number of factors were considered, including mean age, gender, the neurosurgical condition that led to admission, mean stay, infectious complications, acute confusional syndrome, admission into an intensive care unit, need for support from other medical departments, reoperations, mortality during hospitalisation, referral to social-health units, readmission within a month, and mortality within a year. RESULTS: A total of 173 patients on shared monitoring were compared to 189 patients from the previous period. Both groups had similar demographic characteristics. During the analysis, a significant reduction was observed in shared monitoring as regards, mean hospitalisation, infectious complications, admissions into an intensive care unit, the need for support from other medical departments, readmissions within a month, and mortality within a year. CONCLUSIONS: On patients of over 75 years of age, shared geriatric-neurosurgical monitoring reduces mean hospitalisation, morbidity, the need for support from other medical departments, early readmission, and mortality within a year. This strategy prioritises patient care, reduces costs, and rationalises resources

ABSTRACT
El Pott's puffy tumor (PPT) es una rara entidad que en la actualidad representa un abombamiento del cuero cabelludo asociado a un absceso subperióstico y a una osteomielitis craneal, pudiendo acompañarse o no de infección intracraneal. Suele asociarse a la sinusitis frontal, tratándose de una complicación típica, aunque poco frecuente de la misma. Por su parte las osteomielitis causadas por Actinomyces son raras y suelen tener lugar a nivel mandibular, no encontrándose apenas casos de osteomielitis craneal causada por este género bacteriano, en especial tras traumatismo craneoencefálico. Presentamos un caso especialmente poco usual al tratarse de un PPT frontal tras traumatismo cerrado, con componente intracraneal y en el que tras cirugía se aisló Actinomyces como copartícipe de dicha infección, junto con Fusobacterium y Propionibacterium
Pott's puffy tumour (PPT) is a rare entity that involves scalp swelling associated with subperiosteal abscess and cranial osteomyelitis, occasionally accompanied by intracranial infection. It is usually affiliated with frontal sinusitis, which is a typical but infrequent complication. On the contrary, Osteomyelitis by Actinomyces is rare and usually occurs at the mandibular level, with very few cases of cranial osteomyelitis caused by this bacterial specie, especially after traumatic brain injury. We report an exceptionally unusual case of a PPT frontal tumor after blunt trauma (closed head injury), with an intracranial lesion whereby Actinomyces was isolated after surgery, as a co-participant of the mentioned infection besides Fusobacterium and Propionibacterium
