ABSTRACT

INTRODUCTION: Transfontanellar brain ultrasound is an essential tool for monitoring the size of the ventricles in preterm neonates and has many advantages over other alternative diagnostic techniques, including its accessibility and non-use of ionizing radiation. When considering the normal ventricular size, it is essential to have reference measurements based on age-matched populations. The objective of this article is to present our reference measures, based on a sample of preterm infants that we have studied. METHODS: A retrospective observational study was conducted. Measurements of the Levene index, frontal horn thickness, and Evans index were obtained in preterm neonates from 25 to 45 weeks, over a period of 5 years, between January 2016 and December 2020. After applying the exclusion criteria, a sample of 199 patients and 350 ultrasound scans were obtained. The independent samples t-test and the Mann-Whitney test were used for the comparison of samples. RESULTS: The distribution of the right and left Levene indices was normal (Shapiro-Wilk test with p = 0.16 and 0.05, respectively), unlike the thickness distribution of the frontal horns (p < 0.05 on both sides). No significant differences were detected between the sexes (p = 0.08). A linear correlation was found between the biparietal diameter and the Levene index. CONCLUSION: From the results obtained in our study, we present reference tables for ventricular size, with the 3rd, 25th, 50th, 75th, and 97th, being the first ones made in our country.

ABSTRACT

La anestesia neuroaxial en pacientes portadores de dispositivos de derivación de líquido cefalorraquídeo (LCR) se ha asociado clásicamente a un alto riesgo de complicaciones. Con el fin de recabar toda la evidencia disponible, se realizó una búsqueda estructurada de los trabajos publicados en usuarios portadores de estos dispositivos, sometidos a algún tipo de técnica neuroaxial para procedimientos obstétricos o quirúrgicos no relacionados con el mismo, valorando la eficacia de la técnica y las complicaciones perioperatorias. Solo se encontraron series de casos y casos clínicos (n = 72). Se identificó uno de insuficiente cobertura anestésica, que precisó una modificación de la técnica, así como una complicación intraoperatoria con compromiso de seguridad para el sujeto. No se describió ningún caso de infección ni disfunciones posoperatorias del dispositivo relacionadas con el método anestésico. La evidencia hallada es escasa y de baja calidad, lo que no permite establecer conclusiones significativas, aunque los pacientes podrían beneficiarse de una valoración individualizada. (AU)


Neuraxial anesthesia in patients with cerebrospinal fluid (CSF) shunt devices has traditionally been associated with a high risk of complications. In order to gather all available evidence, a structured search was conducted to include published studies involving users of these devices, undergoing any form of neuraxial technique for obstetric or surgical procedures unrelated to them. Effectiveness of the technique and perioperative complications were assessed. Only case series and case reports (n = 72) were identified. One patient was found to have insufficient anesthetic coverage, necessitating a modification of the technique, and another one had an intraoperative complication which compromised the subject's safety. No infection events or postoperative device dysfunction related to the anesthetic method were described. The evidence found is scarce and of low quality, preventing the establishment of significant conclusions. Nevertheless, patients may obtain benefit from an individualized evaluation. (AU)

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 (n = 238). 45.3% of the patients with aneurysmal SAH required an external ventricular drain (EVD) to treat acute hydrocephalus. 11.7% (n = 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.

ABSTRACT

La meningitis criptocócica es una infección infrecuente y con alta morbimortalidad, cuya presentación en pacientes inmunocompetentes es excepcional. Presentamos el caso de un varón de 67 años que ingresó por un cuadro subagudo de alteración de la marcha e incontinencia urinaria. El examen neurológico reveló incapacidad para mantenerse en pie y deterioro de la memoria. Las pruebas de imagen craneales mostraron hidrocefalia tetraventricular obstructiva con áreas de gliosis en los pedúnculos cerebelosos. Se realizó tratamiento endoscópico de la hidrocefalia, con toma de muestras de líquido cefalorraquídeo en las que se observó crecimiento de Cryptococcus neoformans. El paciente mejoró con el tratamiento endoscópico y tras completar la terapia antifúngica intravenosa con anfotericina B liposomal y fluconazol durante diez semanas. La meningitis criptocócica en pacientes inmunocompetentes se trata con antifúngicos. En raras ocasiones se presenta con hidrocefalia, situación que requiere tratamiento quirúrgico mediante derivaciones del líquido cefalorraquídeo o técnicas endoscópicas. (AU)


Cryptococcal meningitis is an infrequent infection with high morbidity and mortality. Its presentation in immuno-competent patients is rare.We present the case of a 67-year-old male who was admitted for subacute symptoms of gait disturbance and urinary incontinence. Neurological examination revealed inability to stand and memory impairment. Cranial im-aging showed obstructive tetraventricular hydrocephalus with areas of gliosis in the cerebellar peduncles. Endo-scopic treatment of hydrocephalus was performed and cerebrospinal fluid samples taken revealing the growth of Cryptococcus neoformans. The patient improved with the endoscopic treatment and after completing intravenous antifungal therapy with liposomal amphotericin B and flu-conazole for ten weeks.Antifungals are used to treat cryptococcal meningitis in immunocompetent patients. On rare occasions, it presents with hydrocephalus, a situation that requires surgical treat-ment using cerebrospinal fluid diversions or endoscopic techniques. (AU)

ABSTRACT

Hydrocephalus, an extremely rare complication of craniocervical junction injuries, is postulated to result from compression of the fourth ventricular cerebrospinal fluid (CSF) outlets by fractured and displaced bone fragments, a swollen upper spinal cord or adhesions formed after a traumatic subarachnoid haemorrhage. We present the case of a 21-year-old woman for whom an injury to the cervical spine complicated by a type I atlanto-occipital dislocation contributed to the development of non-communicating hydrocephalus. The hydrocephalus was probably a consequence of impaired CSF circulation at the fourth ventricular outlets (the foramina of Luschka and Magendie), caused by post-haemorrhagic adhesions formed after severe injury to the craniocervical junction. (AU)


La hidrocefalia, una complicación extremadamente rara de las lesiones de la unión craneocervical se considera resultado del bloqueo de las salidas del líquido cefalorraquídeo (LCR) del cuarto ventrículo por los fragmentos óseos fracturados y desplazados, la inflamación de la médula espinal superior o las adherencias formadas después de una hemorragia subaracnoidea traumática. Se reporta caso clínico de una mujer de 21 años en el que la lesión de la columna cervical complicada por una luxación atlanto-occipital de tipo I contribuyó al desarrollo de una hidrocefalia no comunicante. La hidrocefalia probablemente fue consecuencia de una obstrucción del flujo del LCR fuera del cuarto ventrículo (agujeros de Luschka y Magendie), debida a las adherencias post-hemorrágicas formadas después de la grave lesión de la unión craneocervical.

ABSTRACT

OBJECTIVE: To use third ventricle morphometric variables as a tool for the selection of patients with idiopathic normal pressure hydrocephalus (iNPH) who are candidates for ventriculoperitoneal shunts (VPS). MATERIAL AND METHODS: Retrospective study enrolling patients with iNPH. Katzman infusion test was performed and a Rout > 12 mmHg/mL/min was considered a positive result. The transverse diameter and the volume of the third ventricle were measured in the preoperative MRI. Postoperative improvement was assessed with the NPH score. The results were analysed with SPSS software. RESULTS: 52 patients with a mean age of 76 years were analysed. There was no difference in the diameter of the third ventricle among patients with a positive result and those with a negative result in the infusion test (12.28 vs 11.68 mm; p = 0.14). Neither were difference detected in the ventricle volume of both groups (3.6 vs 3.5cc; p = 0.66). Those patients who improved after VPS had a smaller third ventricle compared to those who did not respond after surgery (11.85 mm vs. 12.96 mm; p = 0.009). Diameter and volume of third ventricle present a significant strong correlation (Pearson correlation coefficient = 0.72; p < 0.0001). CONCLUSION: Morphometric variables of third ventricle may be useful in predicting a good response to VPS in patients with idiopathic normal pressure hydrocephalus.

ABSTRACT

Cerebrospinal fluid (CSF) shunt placement is a commonly performed procedure for patients with hydrocephalus of various etiologies. We present the case of a 68-year-old male patient treated with a ventriculoperitoneal shunt for obstructive hydrocephalus management. Eight years later, a computed tomography (CT) scan detected migration of distal catheter into the pulmonary artery. We conducted a systematic review in Medline database using PubMed search engine to identify previous cases and their management. Our literature review identified eighteen single case reports describing this complication and different strategies to attempt catheter retrieval. To the best authors’ knowledge, this is the first case where conservative management was chosen (AU)


Las derivaciones del líquido cefalorraquídeo son un procedimiento quirúrgico frecuente en el manejo de pacientes con hidrocefalia de diversas etiologías. Presentamos el caso de un paciente varón de 68 años portador de una derivación ventrículo-peritoneal por hidrocefalia obstructiva. Ocho años más tarde se detectó la migración del catéter distal de la derivación hacia la arteria pulmonar en una tomografía computarizada (TC) de tórax. Se ha realizado una revisión sistemática de la literatura en la base de datos MEDLINE utilizando el buscador PubMed para identificar casos descritos de esta complicación y su manejo. Se encontraron 18 casos clínicos que describían esta complicación y diferentes estrategias para intentar recuperar el catéter migrado. Con base en nuestra revisión, el caso descrito es, hasta la fecha, el único en el que se decidió no intentar recuperar el catéter migrado (AU)

ABSTRACT

Introduction: Treatment options for hydrocephalus related to posterior fossa tumors have been extensively studied in the pediatric population, but the value of endoscopic third ventriculostomy in hydrocephalus secondary to vestibular schwannoma in adults, is controversial. A systematic search of the medical literature was carried out in Pubmed/Medline and SciElo for the identification and inclusion of articles, in addition to the preprint servers bioRxiv and medRxiv. The following descriptors were used: "hydrocephalus" and "vestibular schwannomas" or "acoustic neuromas" or "acoustic neurinomas" and "endoscopic third ventriculostomy". The initial search found 195 articles. After selection, 5 articles were chosen for the study. Objective: To specify the role of the endoscopic third ventriculostomy in hydrocephalus secondary to vestibular schwannomas. Development: The articles included a total of 82 patients, in which an improvement of the symptoms was achieved in 86.6% of the cases. The decrease in ventricular diameter was reported in 82.9% of the cases and was only found explicit in 3 articles. Although the failure criteria used were varied, 2 of them predominated: the persistence of progressive symptomatic hydrocephalus and/or the need for shunt placement. Endoscopic third ventriculostomy failure only represented 14.6%. Conclusions: Third ventriculostomy is an acceptable technique with relative success for the treatment of symptomatic obstructive hydrocephalus secondary to vestibular schwannomas.


Introducción: Las opciones de tratamiento para la hidrocefalia relacionada con tumores de fosa posterior han sido ampliamente estudiadas en la población pediátrica, pero es controvertido el valor de la tercer ventriculostomía endoscópica, en la hidrocefalia secundaria a schwanoma vestibular en adultos, previo a la resección del tumor. Se realizó una búsqueda sistemática de la literatura médica en Pubmed/Medline y SciElo para la identificación e inclusión de artículos, además de los servidores de preprint bioRxiv y medRxiv. Se utilizaron los siguientes descriptores: "hydrocephalus" y "vestibular schwannomas" o "acoustic neuromas" o "acoustic neurinomas" y "endoscopic third ventriculostomy". La búsqueda inicial encontró 195 artículos. Después de la selección, se eligieron 5 artículos para el estudio. Objetivo: Especificar el papel de la tercer ventriculostomía endoscópica en la hidrocefalia secundaria a schwanomas vestibulares. Desarrollo: Los artículos incluyeron un total de 82 pacientes, en los que se logró una mejoría de los síntomas en el 86,6 % de los casos. La disminución del diámetro ventricular se reportó en el 82,9 % de los casos y solo se encontró explícita en 3 artículos. Aunque los criterios de fracaso utilizados fueron variados, predominaron dos de ellos: la persistencia de hidrocefalia sintomática progresiva o la necesidad de colocación de derivación. La falla de la tercer ventriculostomía endoscópica solo representó el 14,6 %. Conclusiones: La tercera ventriculostomía endoscópica es una técnica aceptable y con relativo éxito para el tratamiento de la hidrocefalia obstructiva sintomática secundaria a schwanomas vestibulares.

ABSTRACT

RESUMEN El linfoma cerebral primario es una variedad de linfoma no Hodgkin agresivo que se origina en el sistema nervioso central y se diagnostica cuando no hay evidencia de linfoma en ninguna otra parte del cuerpo. Aunque los linfomas sistémicos son más conocidos y estudiados, el linfoma cerebral primario ha sido menos comprendido debido a su baja frecuencia hasta hace algunas décadas. El tratamiento de esta enfermedad sigue siendo objeto de debate. En esta oportunidad se reporta el inusual caso de linfoma B de células grandes (NOS, del inglés Not Other form Specified); asociada a hidrocefalia y su manejo.


ABSTRACT Primary brain lymphoma is a type of aggressive non-Hodgkin lymphoma that originates in the central nervous system and is diagnosed when there is no evidence of lymphoma anywhere else in the body. Although systemic lymphomas are better known and studied, primary brain lymphoma has been less understood due to its low frequency until a few decades ago. The treatment of this disease continues to be debated. On this occasion, the unusual case of large B cell lymphoma NOS associated with hydrocephalus and its management is reported.

ABSTRACT

La derivación ventrículoperitoneal es un procedimiento quirúrgico habitual para eliminar el exceso de líquido cefalorraquídeo (hidrocefalia), asociado a distintas complicaciones. Se presenta el caso de un varón de 60 años con hidrocefalia postraumática al que se le implantó una derivación ventrículoperitoneal. Tras la mejoría clínica inicial, trece meses después desarrolló empeoramiento de la marcha y problemas cognitivos. Las radiografías y tomografía computarizada de tórax mostraron que el catéter distal de la derivación había migrado a la arteria pulmonar. Se extrajo quirúrgicamente el catéter mediante reapertura de la incisión retroauricular previa y tracción manual, sin incidencias. Se implantó un nuevo catéter peritoneal con mejoría clínica inmediata. Dos años después, el paciente permanece asintomático. Este caso ilustra una complicación infrecuente de un procedimiento neuroquirúrgico habitual que puede ser detectada por diferentes profesionales sanitarios; revisamos sus diferentes formas de presentación y estrategias de manejo multidisciplinar a partir de diecinueve casos similares publicados.(AU)


Ventriculoperitoneal shunt placement is a common treatment for hydrocephalus, although not devoid of complications. We report a case of a 60-year-old male who underwent ventriculoperitoneal shunt implantation for the treatment of posttraumatic hydrocephalus. Thirteen months post surgery, after an initial clinical improvement, the patient manifested gait and cognitive disorders. Chest X-rays and computed tomography revealed that the distal shunt catheter had migrated into the pulmonary artery. The catheter was removed by reopening the previous retroauricular incision followed by manual traction, without incidents. A new peritoneal catheter was implanted with immediate clinical improvement and no further complications two years after the second surgery. We communicate a rare complication of a standard neurosurgical procedure that can be detected by different healthcare professionals, and review its various forms of presentation and multidisciplinary management strategies from 19 similar clinical cases found in the literature.(AU)

ABSTRACT

Introducción: la hidrocefalia es una patología neuroquirúrgica que presenta varias alternativas de tratamiento. A pesar de esto, el índice de disfunción y reintervención de los pacientes es considerablemente elevado. Objetivo: describir los resultados de la cirugía neuroendoscópica intraventricular en pacientes operados de hidrocefalia obstructiva. Materiales y métodos: se trata de un estudio observacional, descriptivo, transversal, de serie de casos, en el que se describen variables clínicas, de imagen y quirúrgicas de pacientes operados mediante neuroendoscopia intraventricular. Después de aplicar criterios de inclusión y exclusión, la muestra quedó conformada por cinco pacientes. Resultados: la escala de coma de Glasgow de los pacientes al momento de la cirugía, fue mayor de 12 puntos en todos los casos. El 60 % de los casos presentó un grado 4 en la escala de Frisen para evaluar la gravedad del papiledema. El promedio del índice de Evans medido por tomografía fue de 0,39; el del tercer ventrículo fue de 14,75 mm, mientras que el promedio de los cuernos temporales fue de 4,1 mm. En tres casos se presentaron variedades anatómicas dilatadas de los forámenes de Monro, mientras que en dos presentaban diámetros medianos. El tiempo quirúrgico promedio fue de 45 minutos. Entre las complicaciones posoperatorias estuvo la disfunción del estoma quirúrgico en un paciente con tercer ventriculostomía. Conclusiones: la cirugía neuroendoscópica intraventricular es un método efectivo para tratar pacientes con hidrocefalia obstructiva en pacientes seleccionados.


Introduction: hydrocephalus is a neurosurgical pathology that presents several treatment alternatives. Despite this, the rate of dysfunctions and re-interventions of the patients is considered high. Objective: to describe the results of intraventricular neuro-endoscopic surgery in patients operated on for obstructive hydrocephalus. Materials and methods: this is an observational, descriptive, cross-sectional study, of case series, where clinical, imaging and surgical variables of patients operated by intraventricular neurosurgery are described. After applying inclusion and exclusion criteria, the sample was made up of five patients. Results: the Glasgow coma scale of the patients at the moment of surgery was greater than 12 points in all cases. 60% of the cases presented a grade 4 on Frisen scale to assess the severity of papilledema. The average Evans index, measured by tomography was 0.39; that of the third ventricle was 14.75 mm, while the average of the temporal horns was 4.1 mm. In three cases there were dilated anatomical variants of the foramens of Monro f, while in two they presented medium diameters. The average surgical time was 45 minutes. Surgical stoma dysfunction in one patient with a third ventriculostomy was among the postoperative complications. Conclusions: intraventricular neuro-endoscopic surgery is an effective method for treating patients with obstructive hydrocephalus in selected patients.

ABSTRACT

Introduction Preterm-related posthemorrhagic hydrocephalus is a major cause of neurological impairment and a common indication for a ventriculoperitoneal shunt in infants that are prone to diverse complications. Protocols of diagnosis and treatment are in continuous evolution and require evaluation of their results. Objective To review the clinical characteristics and results of a series of preterm-related posthemorrhagic hydrocephalus needing a definitive shunt from 1982 to 2020 in our institution. As a secondary objective we evaluated the safety of the changes in our protocol of treatment from 2015. Methods Retrospective review, clinical investigation. Results 133 patients were implanted a shunt in the study period. Shunt infection was diagnosed in 15 patients. Proximal shunt obstruction as the first complication was diagnosed in 30% of cases at one year, 37% at two years and 46% at five years. 61 patients developed very small or collapsed ventricles at last follow-up. Two thirds of our patients achieved normal neurological development or mild impairment. Changes in protocol did not significantly modify clinical results although improvement in most outcomes was observed. Mean follow-up was over nine years. Conclusions Clinical outcomes are comparable to previous reported data. Changes in protocol proved to be safe and improved our results. Programmable shunts can be used safely in preterm patients although they may not prevent tendency towards ventricular collapse, which is very common after long follow-up (AU)


Antecedentes La hidrocefalia poshemorrágica del prematuro continúa siendo una causa importante de lesión cerebral perinatal y una indicación frecuente de cirugía derivativa valvular en un grupo de pacientes particularmente vulnerable y expuesto a complicaciones. Los protocolos de diagnóstico y tratamiento están en continua evolución y requieren un análisis de los resultados asociados a ellos. Objetivo Revisar las características clínicas y los resultados de tratamiento en una serie de prematuros con hidrocefalia poshemorrágica en los que se implantó una derivación ventriculoperitoneal permanente en nuestro hospital entre 1982 y 2000. Como objetivo secundario evaluamos la seguridad de los cambios introducidos en nuestro protocolo desde 2015. Material y método Estudio clínico retrospectivo, serie de casos. Resultados 133 prematuros requirieron una derivación ventriculoperitoneal permanente en el tiempo de estudio. En 15 de ellos se diagnosticó una infección del sistema de derivación. La obstrucción proximal de la derivación como primera complicación posquirúrgica ocurrió en un 30% de los pacientes al primer año, en el 37% de los pacientes a los dos años y en el 46% de los casos a los 5 años de seguimiento. 61 pacientes desarrollaron un colapso ventricular clínico o radiológico. Dos tercios de los pacientes presentaron un desarrollo psicomotor normal o un retraso de carácter leve. Los cambios incorporados en nuestro protocolo de tratamiento no modificaron la evolución clínica significativamente, aunque se asociaron a una evolución globalmente más favorable. La media de seguimiento fue superior a los 9 años. Conclusiones Los resultados clínicos presentados se encuentran en línea con las series publicadas, Los cambios incorporados en nuestro protocolo actualizado demostraron ser seguros y pueden asociarse a una evolución más favorable (AU)

Changes in protocol did not significantly modify clinical results although improvement in most outcomes was observed. Mean follow-up was over nine years. CONCLUSIONS: Clinical outcomes are comparable to previous reported data. Changes in protocol proved to be safe and improved our results. Programmable shunts can be used safely in preterm patients although they may not prevent tendency towards ventricular collapse, which is very common after long follow-up.

ABSTRACT

ABSTRACT This case report describes the clinical characteristics and ophthalmic management of a patient who developed corneal perforation due to severe enophthalmos consistent with "silent brain syndrome." A 27-year-old man with a history of congenital hydrocephalus and ventriculoperitoneal shunt was referred with complaints of "sinking of the eyeballs" and progressively decreasing vision in the left eye. Examination revealed severe bilateral enophthalmos in addition to superonasal corneal perforation with iris prolapse in the left eye. The patient underwent therapeutic keratoplasty the next day. Orbital reconstruction with costochondral graft and shunt revision of the intracranial hypotension were performed the next month to prevent further progression.


RESUMO Este relato de caso descreve as características clínicas e o manejo cirúrgico de um paciente que teve perfuração da córnea devido à enoftalmia grave consistente com a "síndrome do cérebro silencioso". Um homem de 27 anos com história de hidrocefalia congênita e derivação ventrículo-peritoneal foi encaminhado com queixas de "afundamento dos globos oculares" e diminuição progressiva da visão no olho esquerdo. O exame revelou enoftalmo bilateral importante, além de perfuração superonasal da córnea com prolapso iriano no olho esquerdo. A paciente foi submetida à ceratoplastia terapêutica no dia seguinte. Foi realizado no mês seguinte a reconstrução da órbita com enxerto costocondral e revisão do shunt para evitar progressão e piora do caso.

ABSTRACT

La derivación ventrículo biliar se describe como un procedimiento alternativo eficaz en el tratamiento de la hidrocefalia. Presentamos el caso de un paciente de 19 años de edad diagnosticado de quiste aracnoideo supraselar e hidrocefalia, portador de doble sistema valvular de derivación ventrículo peritoneal y cisto peritoneal desde la infancia. Tras varios recambios por fallo peritoneal, fue sometido a derivación ventriculoauricular, con complicaciones asociadas y posterior recolocación a peritoneo. Tras nueva disfunción valvular por complicaciones peritoneales, se planteó la derivación ventriculobiliar como tratamiento alternativo para este paciente, que resultó segura y eficaz en la resolución de la clínica del paciente, siendo dado de alta, manteniendo estabilidad clínica durante más de 2 años de seguimiento.

Ventriculo-gallbladder shunt is described as an effective alternative procedure in the treatment of hydrocephalus. We present the case of a 19-year-old patient diagnosed with suprasellar arachnoid cyst since his childhood and hydrocephalus, with a double shunt; ventriculoperitoneal and peritoneal cyst shunt. After several replacements due to peritoneal failure, he underwent ventriculoatrial shunt, with associated complications and subsequent repositioning to the peritoneum. After new valve dysfunction due to peritoneal complications, ventriculo-gallbladder shunt was proposed as an alternative treatment for this patient, which was safe and effective in resolving the patient's symptoms, and the patient was discharged, maintaining clinical stability in the follow-up more than 2 years later.

ABSTRACT

Objetivo. Determinar el papel de la resonancia magnética (RM) cerebral en fetos que presentan ventriculomegalia aislada (VMA) en la evaluación ecográfica del cerebro fetal. Métodos. Se evaluaron retrospectivamente los hallazgos por ecografía y RM de 197 fetos diagnosticados con VMA entre noviembre de 2018 y noviembre de 2020. Se excluyeron los fetos con cariotipos anormales, anomalías adicionales o etiologías relacionadas a ventriculomegalia. Se comparó los resultados de ecografía y RM tanto en términos de medidas ventriculares medias como de grado de VMA. Resultados. Las mediciones de la RM fueron significativamente mayores en la VMA leve (10,33±0,38 mm frente a 11,11±0,51 mm, p<0,001) en comparación con la ecografía. En la VMA leve, la RM midió los ventrículos más anchos que la ecografía, con una diferencia media de 0,78 mm. No hubo diferencias significativas en las mediciones por ecografía y RM en cuanto a los valores medios de la VMA moderada y grave. Hubo buena concordancia entre la ecografía y la RM en la detección de la gravedad de la VMA derecha, izquierda y la media (Κ=0,265, Κ=0,324 y Κ=0,261, respectivamente). Los análisis de regresión lineal revelaron una relación estadísticamente significativa entre las mediciones de ecografía y RM de la VMA derecha, izquierda y la media (p<0,001, p<0,001 y p<0,001, respectivamente). La RM mostró una concordancia perfecta con la ecografía en detectar la lateralidad de la VMA (Κ=1,0, p<0,001). Conclusiones. En fetos con VMA leve detectada por ecografía se debe considerar la evaluación por RM del cerebro fetal para un diagnóstico preciso. Este enfoque puede proporcionar una estrategia eficaz en el manejo prenatal y el asesoramiento de estos embarazos.


Objective: To assess the role of brain magnetic resonance imaging (MRI) in fetuses presenting with isolated ventriculomegaly (IVM) in the ultrasound (US) evaluation of the fetal brain. Methods: US and MRI findings of 197 fetuses diagnosed with IVM between November 2018 and November 2020 were retrospectively evaluated. Fetuses with abnormal karyotypes, additional anomalies, or known etiologies for ventriculomegaly were excluded. US and MRI findings were compared both in terms of mean ventricular measurements and IVM grade. Results: MRI measurements were significantly higher in mild IMV (10.33 ± 0.38 mm vs. 11.11 ± 0.51 mm, p< 0.001) compared to US. In mild IVM, MRI measured ventricles larger than US with a mean difference of 0.78 mm. There was no significant difference in US and MRI measurements in terms of mean values in moderate and severe IVM. There was good agreement between US and MRI in detecting right, left and mean IVM severity (Κ=0.265, Κ=0.324, and Κ=0.261, respectively). Linear regression analyses revealed a statistically significant relationship between US and MRI measurements of the right, left, and mean IVM (p<0.001, p<0.001, and p<0.001, respectively). MRI showed perfect agreement with US in detecting IVM laterality (Κ=1.0, p<0.001). Conclusions: In fetuses with mild IVM detected by US, fetal brain MRI evaluation should be considered for accurate diagnosis. This approach may provide effective strategies in the antenatal management and counseling of these pregnancies.
