[Is there a relationship between white matter lesions associated with migraine and patent foramen ovale? Analysis of a series of patients with chronic migraine]. / ¿Existe relación entre las lesiones de la sustancia blanca asociadas a migraña y el foramen oval permeable? Análisis de una serie de pacientes con migraña crónica.

INTRODUCTION: White matter lesions are more prevalent in migraine patients than in the general population, especially those with a high frequency of attacks. A patent foramen ovale has been described as a possible link between migraine and white matter lesions. AIM: To determine the existence of a possible relationship between a patent foramen ovale and white matter lesions in a series of patients with chronic migraine. PATIENTS AND METHODS: Observational, single-centre, case-control study. Eighty-nine women with chronic migraine were selected. The persistence and characteristics of the patent foramen ovale were assessed by means of a transcranial Doppler study. The patent foramen ovale was classified as small, moderate or massive. Those detected at rest were considered permanent, and the others were classified as latent. The MRI protocol included T1-enhanced sagittal images, FLAIR-T2-enhanced axial images, and a proton density and T2-FSE combined sequence. The white matter lesions were classified as deep, periventricular or both. RESULTS: The prevalence of patent foramen ovale (53.6% versus 48.5%; p = 0.80) and the proportion of massive, permanent patent foramen ovale were similar among patients with and without white matter lesions. Neither was there any difference in the prevalence (55.6% versus 52.6%; p = 1.00) or the characteristics of the patent foramen ovale as a function of the distribution of white matter lesions. CONCLUSION: The results do not suggest that a patent foramen ovale intervenes in the pathophysiology of the white matter lesions observed in patients with migraine.

TITLE: ¿Existe relación entre las lesiones de la sustancia blanca asociadas a migraña y el foramen oval permeable? Análisis de una serie de pacientes con migraña crónica.Introducción. Las lesiones de la sustancia blanca son más prevalentes en los pacientes migrañosos que en la población general, especialmente en los que tienen una alta frecuencia de ataques. El foramen oval permeable se ha descrito como posible nexo de unión entre la migraña y las lesiones de la sustancia blanca. Objetivo. Determinar la existencia de una posible relación entre el foramen oval permeable y las lesiones de la sustancia blanca en una serie de pacientes con migraña crónica. Pacientes y métodos. Estudio observacional, unicéntrico, de casos y controles. Se seleccionó a 89 mujeres con migraña crónica. La persistencia y las características del foramen oval permeable se evaluaron mediante un estudio Doppler transcraneal. El foramen oval permeable se clasificó como pequeño, moderado o masivo. Se consideraron permanentes los detectados en reposo, y latentes, el resto. El protocolo de resonancia magnética incluyó imágenes sagitales potenciadas en T1, axiales potenciadas en FLAIR-T2 y secuencia combinada de densidad protónica y T2-FSE. Las lesiones de la sustancia blanca se clasificaron como profundas, periventriculares o ambas. Resultados. La prevalencia de foramen oval permeable (53,6% frente a 48,5%; p = 0,80) y la proporción de foramen oval permeable masivo y permanente fueron similares entre los pacientes con y sin lesiones de la sustancia blanca. Tampoco se encontraron diferencias en la prevalencia (55,6% frente a 52,6%; p = 1,00) o las características del foramen oval permeable en función de la distribución de las lesiones de la sustancia blanca. Conclusión. Los resultados no sugieren la intervención del foramen oval permeable en la fisiopatología de las lesiones de la sustancia blanca observadas en pacientes migrañosos.

INTRODUCTION: The course of multiple sclerosis is characterised by the development of cerebral atrophy. It is of interest to monitor it in order to evaluate the treatment response, and the preferred technique consists in performing brain volume analyses, which are currently restricted to the field of research. AIM: To analyse the corpus callosum index (CCI) as a possible alternative to the methods based on brain segmentation. SUBJECTS AND METHODS: Our sample was made up of 109 patients with recently diagnosed demyelinating diseases (90 relapsing-remitting multiple sclerosis, 7 primary progressive forms and 12 isolated demyelinating syndromes), and the CCI was calculated in their first magnetic resonance brain scan, together with 101 healthy controls. The sequences of the patients were submitted to a volumetric analysis using the software package MSmetrix. RESULTS: The mean value of the CCI was 0.377 in patients and 0.411 in the controls, and the difference was statistically significant (p < 0.001). The CCI also showed a statistically significant correlation with the brain volume (p < 0.001; r = 0.444) and with the lesional volume in the FLAIR sequence (p < 0.001; r = -0.521), while no association was observed with the volume of grey matter (p = 0.058). CONCLUSIONS: The CCI is related to the overall brain volume obtained by volumetric techniques and may reflect the presence of atrophy in the initial stages of demyelinating diseases, which makes it a fast and easy to calculate alternative.

TITLE: Valoracion de la atrofia cerebral en la esclerosis multiple mediante el indice de cuerpo calloso.Introduccion. La esclerosis multiple se caracteriza en su evolucion por el desarrollo de atrofia cerebral. Su monitorizacion resulta de interes para evaluar la respuesta al tratamiento, y son de eleccion los analisis volumetricos cerebrales, actualmente confinados al ambito de la investigacion. Objetivo. Analizar el indice de cuerpo calloso (ICC) como una posible alternativa a los metodos basados en la segmentacion cerebral. Sujetos y metodos. Se reune a 109 pacientes con enfermedades desmielinizantes de reciente diagnostico (90 con esclerosis multiple remitente recurrente, 7 con formas primarias progresivas y 12 con sindrome desmielinizante aislado) y se calcula el ICC en su primer estudio de resonancia magnetica cerebral, asi como en 101 controles sanos. Las secuencias de los pacientes se someten a analisis volumetrico mediante el programa MSmetrix. Resultados. El valor medio del ICC es de 0,377 en los pacientes y 0,411 en los controles, y la diferencia es estadisticamente significativa (p < 0,001). El ICC muestra una correlacion estadisticamente significativa con el volumen encefalico (p < 0,001; r = 0,444) y con el volumen lesional en secuencia FLAIR (p < 0,001; r = ­0,521), mientras que no se demuestra asociacion con el volumen de la sustancia gris (p = 0,058). Conclusiones. El ICC se relaciona con el volumen encefalico global obtenido mediante tecnicas volumetricas y puede reflejar la presencia de atrofia ya en los estadios iniciales de las enfermedades desmielinizantes, por lo que se presenta como una alternativa de rapido y sencillo calculo.

Técnicas asistidas para el tratamiento endovascular de aneurismas cerebrales complejos o atípicos / Assisted techniques for the endovascular treatment of complex or atypical cerebral aneurysms

A lo largo de los últimos 10 años, el abordaje endovascular de los aneurismas cerebrales ha pasado de ser una alternativa a la cirugía a convertirse en la terapia de elección en la inmensa mayoría de los casos. El constante desarrollo de técnicas asistidas y de nuevos materiales de embolización ha multiplicado sus posibilidades terapéuticas, de modo que en la actualidad es posible tratar con eficacia y seguridad aneurismas que hace tan solo unos años hubiesen sido considerados quirúrgicos. Este continuo avance tecnológico exige a los profesionales implicados en el tratamiento de pacientes con aneurismas cerebrales un alto grado de especialización y una actualización formativa permanente. En el presente trabajo repasamos algunas de las técnicas asistidas más empleadas en la actualidad para el tratamiento endovascular de los aneurismas cerebrales, mostramos sus principales indicaciones, las mejoras que suponen respecto a las técnicas de embolización convencional y sus posibles limitaciones(AU)

In the last ten years, the endovascular approach to the management of cerebral aneurysms has gone from being an alternative to surgery to being the first-choice technique in the vast majority of cases. The continuous development of new assisted techniques and of new materials for embolization have multiplied its therapeutic possibilities, so that safe and efficacious endovascular treatment is now possible for aneurysms that would have required surgery only a few years ago. These continuous technological advances require the professionals that treat patients with cerebral aneurysms to achieve a high degree of specialization and to keep up to date through continuous training. In this article, we review some of the most widely used assisted techniques in the endovascular treatment of cerebral aneurysms, discussing their main indications, their advantages over conventional embolization techniques, and their possible limitations(AU)

Nuestra experiencia en el diagnóstico y tratamiento de los seudoaneurismas cerebrales / Our experience in the diagnosis and treatment of cerebral pseudoaneurysms

Objetivo. Presentar nuestra experiencia en el diagnóstico y tratamiento intravascular de los seudoaneurismas cerebrales. Material y métodos. Presentamos 11 casos de seudoaneurismas (2 traumáticos, 2 micóticos, 3 iatrogénicos y 4 asociados a otras causas) en otros tantos pacientes y analizamos los métodos y criterios diagnósticos, la evolución radiológica y clínica, los criterios tomados en cuenta para la decisión terapéutica, el método de tratamiento y las complicaciones. Resultados. El método de referencia para el diagnóstico es la angiografía por sustracción digital y los criterios diagnósticos en la literatura médica incluyen: aneurismas con cambios morfológicos precoces, aneurismas distales o aneurismas proximales asociados a otro distal, en el contexto clínico adecuado. En los 9 pacientes tratados mediante técnica intravascular se consiguió el objetivo del tratamiento, evitar el resangrado. Conclusiones. Ante la sospecha clínica de un seudoaneurisma todo paciente debe ser valorado mediante arteriografía, principalmente aquellos que presentan hemorragias cerebrales inexplicables y los pacientes con septicemia. La angiografía mediante TC o mediante RM puede sustituir a la arteriografía con una buena rentabilidad diagnóstica. El tratamiento de elección debe ser el intravascular de primera intención y no demorarse excepto que exista una razón que impida el acceso al seudoaneurisma, normalmente un vasoespasmo cerebral grave (AU)

Objective. To present our experience in the diagnosis and intravascular treatment of cerebral pseudoaneurysms. Material and methods. We present 11 pseudoaneurysms (2 traumatic, 2 mycotic, 3 iatrogenic, and 4 with other causes). We analyze the methods and diagnostic criteria, radiological and clinical outcome, the criteria used in making decisions about treatment, the method of treatment, and the complications. Results. Digital subtraction angiography is the gold standard for the diagnosis of cerebral pseudoaneurysms; the diagnostic criteria in the literature include: aneurysms with early morphological changes and distal aneurysms or proximal aneurysms associated with another distal one, in the context of the right symptoms and signs. In the nine patients treated with endovascular techniques, the treatment objective was achieved and rebleeding did not occur. Conclusions. In cases with clinical suspicion of a pseudoaneurysm, the patient should undergo angiography. This is especially important in patients with inexplicable cerebral hemorrhage and in those with septicemia. CT angiography and MR angiography have good diagnostic accuracy and can replace conventional angiography. However, the treatment of choice is endovascular and treatment should not be delayed unless access to the pseudoaneurysm is impeded, usually due to severe cerebral vasospasm (AU)

Cavernoma intraventricular del foramen de Monro: particularidades derivadas de su localización atípica / Intraventricular cavernoma in the foramen of Monro: particularities due to its atypical location

A pesar de que los cavernomas son malformaciones vasculares relativamente frecuentes en el sistema nervioso central, su localización intraventricular, especialmente en la región del foramen de Monro, es muy poco común. Esta localización atípica les confiere una serie de rasgos diferenciales, tanto clínicos como radiológicos, que pueden dificultar en extremo su diagnóstico preoperatorio y conducir a procedimientos ineficaces, como la radioterapia o el abordaje quirúrgico neuroendoscópico, e incluso peligrosos para el paciente, como la biopsia estereotáxica.Dado lo infrecuente de la patología y con el fin de ilustrar estas dificultades diagnósticas, se presenta a continuación un caso de cavernoma intraventricular de la región del foramen de Monro (AU)

Although cavernomas are relatively common vascular malformations in the central nervous system, they are rarely located in the ventricles and are even more rarely located in the region of the foramen of Monro. This atypical location results in a series of differential clinical and radiological characteristics that can make the diagnosis of these lesions extremely difficult and lead to inefficacious procedures like radiotherapy or a neuroendoscopic surgical approach or even to procedures that endanger the patient like stereotactic biopsy.We present a case of intraventricular cavernoma in the region of the foramen of Monro with the aim of illustrating the difficulties involved in the diagnosis of this rare lesion (AU)

Fístulas arteriovenosas renales como causa de hipertensión arterial refractaria / Renal arteriovenous fistulas as a cause of refractory hypertension

Las malformaciones arteriovenosas renales congénitas son una entidad de baja prevalencia y, por tanto, una causa muy poco frecuente de hipertensión arterial.Sin embargo, la potencial posibilidad de ofrecer un tratamiento curativo hace muy importante su diagnóstico, permitiendo modificar el curso natural de la patología hipertensiva refractaria a tratamiento farmacológico.Se presenta el caso de un paciente con fístulas arteriovenosas renales congénitas bilaterales que se trataron mediante 2 técnicas diferentes de embolización en función de la morfología de la fístula y la intensidad del flujo, que consiguió el control sintomatológico de la clínica hipertensiva derivada de dicha patología (AU)

The prevalence of congenital renal arteriovenous malformations is low; for this reason, they are a very uncommon cause of arterial hypertension.However, arterial hypertension due to congenital renal arteriovenous malformations is potentially curable; thus, it is important to reach the correct diagnosis so that the natural course of the hypertension refractory to drug therapy can be modified.We present a case of a patient with bilateral congenital renal arteriovenous fistulas that were treated with two different embolization techniques in function of the morphology of the fistula and the intensity of the flow; treatment achieved control of the clinical symptoms of hypertension (AU)

[Median arcuate ligament syndrome: a controversial entity.]. / Síndrome del ligamento mediano arcuato: una entidad controvertida.

Median arcuate ligament syndrome is a disorder resulting from compression of the origin of the celiac trunk by the arcuate ligament, a fibrous arch that connects the right and left diaphragmatic crura. This is a controversial entity because the clinical manifestations are often nonspecific and isolated compression of the celiac trunk is relatively common in asymptomatic individuals. We report two cases of median arcuate ligament syndrome and review the radiographic features necessary for the imaging workup of this entity.

Síndrome del ligamento mediano arcuato: una entidad controvertida / Median arcuate ligament syndrome: a controversial entity

El síndrome del ligamento mediano arcuato resulta de la compresión del origen del tronco celíaco por el ligamento arcuato, una banda fibrosa que une las 2 cruras diafragmáticas. Se trata de una entidad controvertida, dado lo inespecífico de su sintomatología y la relativa frecuencia con la que se presenta la compresión aislada del tronco celíaco en sujetos asintomáticos. A propósito de 2 casos se revisan los hallazgos por imagen que permitirán al radiólogo llevar a cabo una adecuada valoración de esta entidad (AU)

Características clínico-patológicas del carcinoma de células renales detectado incidentalmente mediante estudios radiológicos / Clinicopathologic features of renal cell carcinoma incidentally detected through radiological studies

Objetivos: Evaluar el motivo de diagnóstico del carcinoma renal y su variación a lo largo de los años en los Servicios de Radiodiagnóstico 1 y Urología 1 del Hospital Universitario Central de Asturias (HUCA), comparando los periodos 1970-1995 y 1996-2005 y determinar si el hallazgo incidental puede explicar de forma independiente el pronóstico de estos tumores o es dependiente de sus características clínico-patológicas. Material y métodos: Se llevó a cabo una revisión exhaustiva de las historias clínicas, de manera retrospectiva, de 373 carcinomas de células renales sometidos a resección quirúrgica entre los años 1970 y 2005, recogiéndose unos datos según un protocolo establecido. Resultados: De los 373 tumores de nuestra serie, 146 (39,1%) fueron diagnosticados según nuestros criterios de forma incidental, mientras que 227 (60,9%) lo fueron por presentar clínica sospechosa de presencia de un tumor. Cuando realizamos el recuento distribuyendo estos pacientes en dos grupos, por un lado los diagnosticados entre los años 1970-1995, y por otro lado los diagnosticados entre 1996-2005, observamos un incremento significativo en el número de tumores diagnosticados de forma incidental en el segundo periodo. Encontramos como factores independientes en la supervivencia cáncer específica la presencia de metástasis, la invasión microvascular de la pieza quirúrgica y el tratamiento de la recidiva (quirúrgico vs otros), mientras que los factores independientes de la recidiva resultaron ser el grado nuclear, la presencia de adenopatías y el estadio T3, por tanto la presencia de clínica no fue un factor independiente de recidivani de supervivencia cáncer específico. Conclusiones: Clásicamente el carcinoma de células renales se diagnosticaba cuando presentaba síntomas locales (la hematuria y el dolor lumbar, eran los más frecuentes), síntomas derivados de las metástasis o por la expresión de un síndrome paraneoplásico. Desde la generalización de la ecografía y la tomografía computerizada (TC) en el estudio de la patología abdominal ha aumentado de forma espectacular el descubrimiento de adenocarcinomas renales asintomáticos. Cabe destacar, en nuestro estudio, que a pesar de que los pacientes diagnosticados con tumores incidentales presentaron un mayor tiempo libre de enfermedad y de supervivencia sin embargo, la presencia de clínica no fue un factor independiente ni de recidiva ni de supervivencia cáncer específico (AU)

Objectives: To evaluate the reason for diagnosis of renal cell carcinoma and its variation over the years in Radiology 1 and Urology 1departments of the Asturias Central Universitary Hospital (HUCA) comparing periods 1970-1995 and 1996-2005 and determine whether incidental findings may explain in an independent the prognosis of these tumors or it is dependent on its clinic pathologic characteristics. Material and methods: We conducted retrospectively, an exhaustive review of medical records of 373 renal cell carcinoma patients that underwent surgical resection during the period 1970-2005, collecting data according to a set protocol. Results: Of the 373 tumors in our series, 146 (39,1%) were diagnosed according to our criteria incidentally, while 227 (60,9%) were diagnosed due to clinical suspicion of a tumor presence. We observed a significant increase in the number of tumors incidentally diagnosed in the second period, when we performed the counting distributing these patients into two groups, firstly those diagnosed between the years 1970-1995 and, secondly, those diagnosed between 1996-2005. We found metastasis, microvascular invasion of surgical piece and treatment of the recurrence as independent factors for specific cancer survival, while nuclear grade, the presence of lymphadenopathies and T3 stage were found as independent factors for recurrence. Conclusions: Classically renal cell carcinoma was diagnosed when local symptoms were present (hematuria and back pain, were the most common), symptoms associated with metastasis, or the expression of a paraneoplastic syndrome. The discovery of asymptomatic renal cell carcinomas has dramatically increased, since the widespread use of ultrasound and computed tomography (CT) in the study of abdominal pathology. It is worth mentioning that, in our study, although patients diagnosed with incidental tumors had a longer time free to recurrence and survival, however, the presence of clinic was not an independent risk factor for recurrence or cancer-specific survival (AU)
