RESUMO

Behçet's disease (BD) is a systemic inflammatory vascular disease with several clinical manifestations and geographical differences in disease expression. In Middle Eastern countries it is one of the most common causes of cerebral venous thrombosis. We report a 29-year-old female admitted for acute headache and vomiting. A magnetic resonance image showed a large thrombosis of sagital and transverse sinuses. She developed oral and genital ulcers a week later. Ophthalmologic examination revealed left anterior uveitis and ipsilateral papilledema. Multiple studies ruled out a hypercoagulability syndrome. The patient used oral contraceptives. Anticoagulant therapy was prescribed. A biopsy of a genital ulcer demonstrated diffuse lymphocytic infiltration with vasculitis. After treatment with topical and systemic corticoids, her condition improved. Venous sinus thrombosis followed by oral and genital ulcers is an unusual presentation of Behçet's disease.

RESUMO

OBJECTIVE: To analyze a series of 15 patients with cerebral venous thrombosis (CVT) who had follow-ups at the neurology service of Santa Casa de Belo Horizonte Hospital from April, 2007 to December, 2008. These results were compared with data in literature. METHODS: Cases were evaluated by retrospective study of the epidemiologic characteristics, signs and symptoms, risk factors and prognosis of 15 patients with cerebral venous thrombosis. RESULTS: Diagnoses were reached through magnetic resonance imaging of the brain in 14 cases and through an angiography in one. The main risk factors identified were use of birth control pills (40%) and history of family member with deep venous thrombosis. Thrombophilia was found in two patients (13%). The veins more affected were the transverse sinus (73%) followed by the upper sagital sinus (53%). Four patients had strokes and five had only headaches as isolated symptoms. Twelve patients were treated with heparin and oral anticoagulant. CONCLUSION: Treatment with heparin in the acute phase followed by an oral anticoagulant was shown as safe and efficient to prevent worsening of the disease, recurrence and for quick improvement of neurological symptoms of all treated patients. CVT is one of the possible diagnoses of secondary headache even in patients with no signs and symptoms.

RESUMO

OBJETIVO: Analisar uma série de 15 pacientes com trombose venosa cerebral (TVC) e comparar os resultados com dados da literatura. MÉTODOS: Foram avaliados, por meio de estudo retrospectivo, transversal e descritivo, as características epidemiológicas, o quadro clínico, os fatores de risco e o prognóstico de 15 pacientes com TVC admitidos no serviço de Neurologia da Santa Casa de Belo Horizonte no período de abril de 2007 a Dezembro de 2008. RESULTADOS: O diagnóstico de TVC foi confirmado por exame de ressonância nuclear magnética de encéfalo em 14 casos e por angiografia cerebral em um caso. Os principais fatores de risco identificados foram o uso do anticoncepcional oral (40 por cento) e uma história prévia ou familiar de trombose venosa profunda. Trombofilia foi encontrada em dois pacientes (13 por cento). O seio mais acometido foi o transverso (73 por cento), seguido pelo sagital superior, em 53 por cento. Quatro pacientes apresentaram acidente vascular cerebral e outros 5 apresentaram-se apenas com cefaleia isolada. Doze pacientes foram tratados com heparina e anticoagulação oral sequencial. CONCLUSÃO: A terapêutica com heparina na fase aguda seguida do anticoagulante oral demonstrou-se segura e eficaz na prevenção da progressão da doença, de sua recidiva e na rápida recuperação do quadro neurológico de todos os pacientes tratados. A TVC deve ser considerada no diagnóstico de cefaleia secundária mesmo em pacientes com ausência de outros sinais ou sintomas.

RESUMO

INTRODUCTION: Thrombosis of the cerebral venous sinuses (TCVS) is an infrequent entity that still represents a challenge in health care. PATIENTS AND METHODS: A descriptive study involving the evaluation of the medical records of patients that met the following criteria: over 18 years of age with a diagnosis of TCVS confirmed by CAT scan or cranial MRI, the absence of a history of intracranial surgery in the previous six months and absence of a history of intracranial infection. RESULTS: A total of 15 patients (14 females and one male) were found with an average age of 28.6 years. The time required for the development of the most frequent symptoms was 1 10 days (60%). The usual presentation was a syndrome of intracranial hypertension with focalisation and encephalopathy. Risk factors were identified in 13 patients (87%). TCVS was diagnosed by cranial MRI in the case of 14 patients (93%), by CAT scanning in one (7%) and this was also used to orient diagnosis in 12 cases (80%). The most frequently affected sinuses were the superior longitudinal and transverse, in 10 cases each (66%), and venous infarctions were also detected in 10 patients (66%). In the patients in whom we were able to evaluate clotting disorders, it was found that the only individual who displayed activated protein C resistance was positive, three out of four patients had a protein C deficiency and four out of six had an antithrombin III deficiency. CONCLUSION: TCVS presents as an intracranial hypertension syndrome and it is possible to find risk factors in as many as 85% of the cases.

RESUMO

Se presentan seis casos de trombosis venosa cerebral durante el embarazo y el puerperio. Cinco durante el embarazo y uno en el puerperio. Se discute la etiopatogenia, los aspectos clínicos diagnóstico diferencial, diagnóstico por imagenes y los alcances terapéuticos. Tratamiento activo con anticoagulantes fue llevado a cabo en dos pacientes y los otros fueron manejados sintomáticamente. Tres pacientes fallecieron y tres sobrevivieron todos con secuelas neurológicas.

RESUMO

The diagnosis of the cavernous sinus thrombosis requires a careful clinical evaluation and appropriate radiological methods. In this report we describe the magnetic resonance imaging findings in a patient with the clinical diagnosis of cavernous sinus disorder and its correlation with orbital phlebography and histopathologic studies.

RESUMO

Se presentan 9 casos de trombosis de senos venosos cerebrales diagnosticados en el Hospital San Juan de Dios entre 1954 y 1987. Se encontraron 5 hombres y 4 mujeres con una edad promedio de 27.3 anos. Todos presentaban una o mas condiciones predisponentes: utilizacion de anticonceptivos orales, sepsis, carcinoma, trauma craneano y sinusitis. Los cuadros clinicos neurologicos correspondieron a diversos sindromes clinicos como sindrome de hipertension endocraneana, sindrome convulsivo y sindrome mental, y en todos los casos hubo manifestaciones clinicas relacionadas con la enfermedad de base. Solo en tres pacientes se hizo el diagnostico en vida y en dos de ellos fue posible iniciar terapeutica anticoagulante y evitar la aparicion de secuelas. Los nuevos metodos de diagnostico actualmente disponibles en nuestro medio, facilitan el diagnostico precoz y la iniciacion oportuna de la anticoagulacion, aceptada como el tratamiento de eleccion en esta entidad.
