Tratamiento combinado, mediante embolización y cirugía, de los aneurismas cerebrales rotos con hematoma cerebral e hipertensión intracraneal: Análisis retrospectivo y revisión de la bibliografía / Combined surgery and embolization to treat ruptured cerebral aneurysms with cerebral hematoma and intracranial hypertension: a retrospective analysis and review of the literature

Objetivo: Valorar si la técnica de embolización urgente del aneurisma cerebral y posterior cirugía del hematoma es segura y eficaz en pacientes con hematoma y signos de hipertensión intracraneal por rotura de aneurisma cerebral. Métodos: Se incluyeron 23 pacientes consecutivos con aneurisma cerebral roto y mal estado clínico debido a un hematoma intracraneal, ambos tratamientos completados en las primeras 4 horas del inicio de la clínica. Todos los pacientes presentaban signos clínicos de hipertensión intracraneal y/o alteración del nivel conciencia, incluido coma por deterioro rostrocaudal. Se valoró la eficacia de la técnica mediante el grado de cierre de los aneurismas y el pronóstico de los pacientes un mes después, y la seguridad, mediante el análisis de las complicaciones de los tratamientos. Resultados: El 91,3% de los pacientes tenía un aneurisma localizado en la arteria cerebral media (ACM). Todos los pacientes presentaban un valor de 4 en la escala de Fisher y de IV-V en la escala de Hunt y Hess. El tiempo medio desde la identificación del aneurisma en la tomografía computarizada hasta la embolización del aneurisma fue de 115 minutos. Se usó balón de remodeling en el 78% de los casos, con el que se logró un cierre adecuado en el 82,6% de los pacientes. Durante la cirugía se colocó un drenaje ventricular en 9 (39,1%) pacientes. Al mes, 13 (56,5%) pacientes eran independientes, con una mortalidad del 13%. No existieron resangrados. Conclusión: En nuestra experiencia, el tratamiento combinado mediante embolización del aneurisma y descompresión quirúrgica con evacuación del hematoma es segura y efectiva, y es una alternativa al tratamiento quirúrgico aislado

Objective: To determine whether the urgent embolization of a cerebral aneurysms and posterior surgery on cerebral hematomas is safe and efficacious in patients with hematomas and signs of intracranial hypertension due to the rupture of cerebral aneurysms. Methods: We included 23 consecutive patients in poor clinical condition due to an intracranial hematoma caused by a ruptured cerebral aneurysm who were treated with both embolization and surgery within 4 hours of the onset of symptoms. All patients had clinical signs of intracranial hypertension and / or altered levels of consciousness, including coma due to rostrocaudal deterioration. We evaluated the efficacy of the combined technique by determining the degree of closure of the aneurysms and the patients' prognosis one month after the procedures; we evaluated safety by analyzing the complications of the treatments. Results: All but two of the patients (21/23; 91.3%) had an aneurysm of the middle cerebral artery. All patients scored 4 on the Fisher scale and were classified as Hunt and Hess IV or V. The mean time from the identification of the aneurysm on computed tomography to embolization was 115minutes. A balloon remodeling technique was used in 18 (78%) patients; embolization achieved adequate closure in 19 (82.6%) patients. During surgery, a ventricular drain was placed in 9 (39.1%) patients. One month after treatment, 13 (56.5%) patients were functionally independent and 3 (13%) had died. No episodes of rebleeding were observed. Conclusion: In our experience, combined treatment including embolization of the aneurysm and surgical decompression with evacuation of the hematoma is a safe and effective alternative to surgical treatment alone

[Description of a series of hospital patients with a spinal fistula]. / Descripcion de una serie hospitalaria de pacientes con fistula espinal.

INTRODUCTION: Although spinal fistulas account for 70% of all spinal arteriovenous malformations, they are an underdiagnosed condition. The arteriovenous shunt produces vascular congestion that gives rise to a progressive myelopathy, sometimes irreversible if it is not treated in the early stages. AIM: To describe the clinicoradiological characteristics of a series of patients with spinal fistulas. PATIENTS AND METHODS: A retrospective search was conducted for patients diagnosed with a spinal fistula who were hospitalised in the neuroscience area of a tertiary care hospital. RESULTS: A total of 19 patients (7 females and 12 males) were identified, with a mean age of 56 years. The spinal fistula was type I in 79% of patients, and a dorsal location was the most frequent. Most of the cases (90%) presented a progressive course. Magnetic resonance imaging was used in the diagnosis in 74% of the patients. In four cases angiography was required to reach a diagnosis, and in one of them it was necessary to perform an intraoperative biopsy. Three lumbar punctures were performed, two of which revealed lymphocytic pleocytosis and high protein levels in cerebrospinal fluid. The average diagnostic delay was nine months. Seventy-nine per cent of the patients were treated and only 10% of them improved. CONCLUSIONS: When faced with a clinical picture suggestive of a spinal fistula, a diagnostic spinal angiography must be carried out, although the patient under study may present atypical cerebrospinal fluid characteristics and normal results in magnetic resonance imaging of the spinal cord.

TITLE: Descripcion de una serie hospitalaria de pacientes con fistula espinal.Introduccion. Aunque las fistulas espinales suponen el 70% de las malformaciones arteriovenosas espinales, son una entidad infradiagnosticada. El shunt arteriovenoso produce una congestion vascular que da lugar a una mielopatia progresiva, en ocasiones irreversible si no se trata de forma precoz. Objetivo. Describir las caracteristicas clinicorradiologicas de una serie de pacientes con fistula espinal. Pacientes y metodos. Se realizo una busqueda retrospectiva de pacientes con diagnostico de fistula espinal ingresados en el area de neurociencias de un hospital de tercer nivel asistencial. Resultados. Se identificaron 19 pacientes (7 mujeres y 12 varones) con una edad media de 56 años. La fistula espinal fue de tipo I en un 79% de los pacientes y la localizacion dorsal fue la mas frecuente. La mayoria de los casos presento un curso progresivo (90%). Un 74% de los pacientes se diagnostico mediante resonancia magnetica. En cuatro casos fue necesaria la realizacion de una angiografia para llegar al diagnostico, y en uno de ellos se preciso una biopsia intraoperatoria. Se realizaron tres punciones lumbares, en dos de las cuales se objetivo pleocitosis linfocitaria e hiperproteinorraquia. El retraso diagnostico medio fue de nueve meses. Se trato a un 79% de los pacientes, y de ellos solo mejoro el 10%. Conclusiones. Ante una clinica sugestiva de fistula espinal, debe realizarse una angiografia espinal diagnostica aunque el paciente estudiado pueda presentar caracteristicas licuorales atipicas y normalidad en la resonancia magnetica medular.
