[Occult anterior sacral meningocele]. / Meningocele sacro anterior oculto.

BACKGROUND: The anterior sacral meningocele is a rare form of spinal dysraphism located in the presacral extraperitoneal space. It is generally asymptomatic and appears as a small pelvic mass. CASE DESCRIPTION: We present a case of a 10 year-old male that develops a bacteria meningitis because of a pararectal abscess that is connected with an anterior sacral meningocele. We successfully treated it using a posterior approach. CONCLUSION: The aim of the surgery is to repair the dural defect and to obliterate the communication between the thecal sac and the herniation defect. The posterior approach is the simplest and most effective surgical technique because the lower risk of neurological injury than the anterior approach.

Meningocele sacro anterior oculto / Occult anterior sacral meningocele

Introducción. El meningocele sacro anterior es una rara forma de disrafismo espinal, localizado en el espacio presacro extraperitoneal. Generalmente es asintomático y suele presentarse como una pequeña masa pélvica. Caso clínico. Presentamos el caso de un niño de 10 años de edad que desarrolla una meningitis bacteriana consecuencia de un absceso pararectal que se comunica con una cavidad meningocélica sacra anterior. Recibe tratamiento quirúrgico realizándose con éxito un abor­daje posterior. Conclusión. La finalidad de la cirugía es reparar el defecto dural y obliterar la comunicación existente entre el saco tecal y el defecto herniario. El abordaje posterior es la técnica quirúrgica más efectiva puesto que tiene menor riesgo de daño neurológico que el abor­daje anterior (AU)

[Sinus pericranii. A case report]. / Sinus pericranii. A propósito de un caso.

INTRODUCTION: Sinus pericranii is an unusual vascular anomaly characterised by communication between diploic and epicranial veins and a dural sinus. It is therefore an abnormal communication between the intracranial and extracranial circulatory systems. CASE REPORT: We report a case of sinus pericranii in an 8-month-old boy, with typical clinical and radiological manifestations. CONCLUSIONS: Sinus pericranii is a rare condition in paediatric pathology, which is generally asymptomatic and is usually found in the area of the anterior fontanelle. The fundamental diagnostic method is magnetic resonance imaging of the brain with and without contrast; surgery is the preferred treatment, although rare cases of spontaneous thrombosis have been reported.

Sinus pericranii. A propósito de un caso / Sinus pericranii, A case report

Introducción. El sinus pericranii es una anomalía vascular poco frecuente consistente en una comunicación entre un seno dural y las venas diploicas y epicraneales. Es pues una comunicación anómala entre la circulación intra y extracraneal.Caso clínico. Presentamos un caso de sinus pericranii en un niño de 8 meses, con unas típicas manifestaciones clínicas y radiológicas. Conclusiones. El sinus pericranii es una entidad poco frecuente en la patología pediátrica, que cursa generalmente asintomática, cuya localización suele ser en el sector de la fontanela anterior. El método diagnóstico fundamental es la resonancia magnética cerebral con y sin contraste, siendo su tratamiento de elección el quirúrgico, aunque se ha descrito enraros casos su trombosis espontanea

[Anterior approach complications in cervical spine pathology]. / Complicaciones del abordaje anterior en la patología de la columna cervical.

OBJECTIVE: To analyze cervical discectomy complications with anterior approach. MATERIAL AND METHODS: Retrospectively clinical cases series of 193 patients, between December 1989 to December 2004, in the Hospital Germans Trias i Pujol in Badalona. We analyzed complications arisen with cervical anterior approach and its relation with differents procedures. Demographic variables (age, sex), clinical variables (onset symptoms, cervical pathology cause, complication type, and duration time) and surgical variables (operated levels number, procedure, graft used) were analyzed. We made a statistical analysis with multivariant analysis, T-Student test and Chi-square test to analyze the relation between the complications and different studied variables. RESULTS: We found complications in 50 patients (25.91%). Most frequent has been dysphagia, present in 15 patients. Most of them appear with transitory form (13 patients) and in very few occasions permanent form (2 patients). T-Student test in statistical analysis showed no statistically significant differences (p=0.431) between the ages and complications, and were not statistically significant differences, used Chi-square test, in sex (p=0.515), in onset symptoms (p=0.923), in pathology origin (p=0.364), in a procedure(p=0.295), and graft used (p=0.382). We found statistically significant differences in operated levels number (p=0.018) with a ratio for the advantages (single /multiple) of 2.221. Multivariant analysis with linear regression model considering age, sex and operated levels number, showed that persistist the risk of complications in operated number levels, independently of the age or sex, being the multiple spaces a 117.3% more frequent than the single space (OR 2.173; IC95% 1.104-4.279). CONCLUSIONS: 1. Cervical anterior approach, is a simple technique, and safe surgically procedure with under number of complications. 2. Dysphagia is most frequent complication, but it is inherent to the procedure and it is solved without treatment in most ocasions. 3. Have been many the procedures used for the cervical spine fixation, with more than 40 years of experience, and still it is to define as he is the best one. It would be necessary more studies of prospective multicentric character to be able to compare clinical, radiological results, and the presence of complications.

Complicaciones del abordaje anterior en la patología de la columna cervical / Anterior approach complications in cervical spine pathology

Objetivo. Analizar las complicaciones de pacientes intervenidos mediante abordaje cervical anterior en la patología de la columna. Material y métodos. Estudio retrospectivo de una serie de 193 casos clínicos, entre Diciembre de 1989 y Diciembre de 2004, en el Hospital Germans Trias i Pujol de Badalona, donde se analizaron las complicaciones surgidas con el abordaje cervical anterior y su relación con las distintas técnicas aplicadas. Se analizaron variables sociodemográficas (edad, sexo), variables clínicas (sintomatología inicial, origen de la patología cervical, tipo de complicación, y tiempo de duración de la complicación)y quirúrgicas (número de niveles intervenidos, nivel intervenido, tipo de intervención realizada, tipo de injerto utilizado). A partir de los datos obtenidos se realizó un análisis estadístico con modelos de análisis multivariante, con la prueba de T-Student y con el test de Chi-cuadrado para analizar la relación entre las complicaciones y las distintas variables estudiadas. Resultados. De todos los individuos estudiados (193), hallamos complicaciones en 50 pacientes (25,91%). De ellas, la más frecuente fue la disfagia, presente en 15 pacientes. La mayoría de ellas se presentaron de forma transitoria (13 pacientes) y en muy pocas ocasiones de forma permanente (2 pacientes). El análisis estadístico mediante la prueba de la T de Student mostró que no existían diferencias estadísticamente significativas(p=0,431) entre las edades de los pacientes que habían presentado complicaciones frente a los que no, y tampoco se encontraron diferencias estadísticamente significativas, utilizado el test de la Chi-cuadrado, respecto el sexo (p=0,515), síntomas iniciales p=0,923), origen de la patología (p=0,364), tipo de intervención realizada (p=0,295), y tipo de injerto utilizado (p=0,382,). Donde sí encontramos diferencias estadísticamente significativas fue en el número de niveles intervenidos (p=0,018) con una razón de las ventajas para el número de niveles (único/múltiple) de 2,221. Con el análisis multivariante siguiendo en modelo de regresión lineal considerando edad, sexo y número de niveles intervenidos, observamos que persistía el riesgo de complicaciones del número de espacios intervenidos, independientemente de la edad o el sexo, siendo los múltiples espacios un 117,3% más frecuente que la intervención de un único (OR 2,173; IC95% 1,104-4,279). Conclusiones. 1. La cirugía de la columna cervical por vía anterior, es una técnica simple, y un procedimiento quirúrgicamente seguro con un número bajo de complicaciones. 2. La disfagia es la complicación más frecuente, pero que se encuentra casi inherente al procedimiento y en la mayoría de ocasiones se resuelve sin tratamiento. 3. Han sido muchos los procedimientos utilizados para la fijación de la columna cervical, con más de 40 años de experiencia, y aún queda por definir cual es el mejor. Harían falta más estudios de carácter rmulticéntrico y de cohorte prospectiva para poder comparar resultados clínicos, radiológicos, y la presencia de complicaciones
