    No full text
    The clinical findings and the results of surgical treatment in 16 patients with spinal dermoid or epidermoid tumors are reported. In 9 patients the tumor capsule adhered so tightly to the nervous tissue that part of it was left in situ. In a follow-up study ranging from 5 to 30 years with a mean of 14.2 years only 1 patient had a recurrence of the tumor and 10 patients resumed a normal working life

    Ethylene oxide sterilization of autologous bone flaps following decompressive craniectomy.

    In patients undergoing decompressive craniectomy, the bone flap is temporarily preserved either in the subcutaneous tissue of the patient or frozen. However, there are some drawbacks related to these methods. In 16 patients in whom the bone flap was removed for decompressive craniectomy, the bone was firstly washed in hydrogen peroxide and then placed in hermetically-sealed bags and sterilized using ethylene oxide. The bone was repositioned after an average period of 4.3 months. One patient sustained an infection of the surgical wound which required permanent exclusion of the bone flap. In all the others, esthetic and functional results were good after an average follow-up of 20 months. Control CT-scan of the bone flap demonstrated preservation of its structural features with fusion of the bone margins and revitalization of the flap. On MRI a subdural space was again visible. Sterilization of the bone flap with ethylene oxide in patients undergoing decompressive craniectomy avoids some of the drawbacks related to the techniques currently used. The easiness, low cost, good aesthetic and functional results of this procedure make it a valid alternative to other techniques for preservation of autologous bone in decompressive craniectomies

    Decompressive craniotomy (DC) is applied to treat post-traumatic intracranial hypertension (ICH). The purpose of this study is to identify prognostic factors and complications of unilateral DC. Eighty-nine patients submited to unilateral DC were retrospectively analyzed over a period of 30 months. Qui square independent test and Fisher test were used to identify prognostic factors. The majority of patients were male (87%). Traffic accidents had occurred in 47% of the cases. 64% of the patients had suffered severe head injury, while pupillary abnormalities were already present in 34%. Brain swelling plus acute subdural hematoma were the most common tomographic findings (64%). Complications occurred in 34.8% of the patients: subdural effusions in 10 (11.2%), hydrocephalus in 7 (7.9%) and infection in 14 (15.7%). The admittance Glasgow coma scale was a statistically significant predictor of outcome ( p=0.0309).<br>A craniotomia descompressiva (CD) é técnica utilizada para tratamento da hipertensão intracraniana (HIC) pós-traumática. O objetivo do estudo foi determinar fatores prognósticos e complicações nos pacientes submetidos a esta técnica. Realizou-se estudo retrospectivo de 89 pacientes submetidos à CD unilateral para tratamento da HIC pós-traumática durante 30 meses. Utilizou-se testes do Qui-quadrado de independência e teste exato de Fisher para análise de fatores independentes de prognóstico. A maioria dos pacientes era do sexo masculino (87%). A causa mais comum foi o acidente de trânsito (47%). A maioria apresentava traumatismo cranioencefálico grave (64%), 34% já apresentavam anisocoria. O achado tomográfico mais comum foi a associação entre tumefação cerebral e hematoma subdural agudo (64%). Em 34,8% dos pacientes houve complicações inerentes à técnica: coleção subdural (11,2%), hidrocefalia (7,9%) e infecção (15,7%). A escala de coma de Glasgow à admissão correlacionou-se estatisticamente como fator prognóstico (p=0,0309)
