Intradural Extramedullary Spinal Metastasis of a Kidney Cancer: Case Report

Objective To report a case of intradural extramedullary metastasis originated from a kidney neoplasm. Metastases in this topography occur in a low frequency, especially considering that the primary tumor was located along the urinary system. Case Report Amale adult begins to present with pain in the lower limbs and develops flaccid paraparesis of the pelvic limbs, also attacking the control of the sphincter. The patient had a previous history of right nephrectomy due to a kidney neoplasm. After investigation with imaging exams, ametastatic lesion was found to be the source of the symptoms. The patient was surgically treated by the neurosurgery team of the hospital. Conclusion Cases like this are not common, and considering the low incidence of these cases and the nonspecific symptoms, such as pain, we do not always come up with the hypothesis of a metastasis in this topography. The surgical treatment, although it is a palliative feature, has an important part inmaintaining the performance and the quality of life of the patient.

Decompressive Craniectomy (DC) - Comparative Study of 30-Day Mortality in Surgeries of Severe Brain Trauma with Subdural Hematoma, with and without DC

Objective Compare 30 days mortality of patients harboring acute subdural hematomas in two series, one treated only by wide aspiration of hematoma and other with aspiration followed by decompressive craniectomy. Methods Comparing retrospectively two series of ASD with and without DC. Involved 81 TBI patients with acute subdural hematoma and GCS 8 (Jan 2000 to Nov 2014) arranged into two groups. Group 1 - 58 cases underwent to DC. Group 2 - 23 patients underwent only hematoma aspiration. Results Group 1 showed 44.8% mortality directly due to brain lesion within 30 days. The most frequent associated lesion were contusion in 37.2%. Group 2 the mortality within 30 days was 47.8%. The majority of deaths (82%) resulted from uncontrollable brain swelling, midline shift was present in 94.7% of patients. Conclusion High admission GCS and age less than 50 remain better outcome predictor in 30 days survival for patients undergoing surgery of traumatic ASDH.

Objetivo Comparar a mortalidade em 30 dias de pacientes que sofreram hematoma subdural agudo em duas séries, uma tratada por aspiração do hematoma e outro por aspiração seguida de craniectomia descompressiva. Métodos Comparar retrospectivamente duas séries de HSD com e sem CD. Envolveu 81 pacientes com TCE com hematoma subdural agudo e GCS 8 (Jan 2000 a Nov 2014) em dois grupos. Grupo 1­58 casos tratados submetidos a CD. Grupo 2­23 pacientes submetidos a drenagem do hematoma somente. Resultados Grupo 1 apresentou 44,8% de mortalidade diretamente devido a lesão cerebral dentro de 30 dias. A mais comum lesão associada era contusão em 37,2%. Grupo 2 a mortalidade dentro de 30 dias foi 47,8%. A maioria dos óbitos (82) resultou de edema cerebral incontrolável, desvio de linha média estava presente em 94,7% dos pacientes. Conclusão Alto GCS de admissão e idade menor que 50 anos permanecem melhores preditores de desfecho na mortalidade em 30 dias para paciente submetidas a cirurgia de hematoma subdural agudo.

Pericallosal Aneurysms: Effectiveness of Endovascular Management

Objective Clarify the safety and efficacy of the endovascular treatment of distal anterior cerebral artery (DACA) aneurysms, reporting outcomes of the aneurysms coiled in our service were compared with series of microsurgical treatment. The impact of embolization on ruptured or unruptured aneurysms remains controversial according to the current data, considering aneurysm from this topography should be aggressively treated due to their high incidence of rupture, currently there is a tend to prefer endovascular treatment. Methods We conducted a retrospective cohort study with 1092 patients admitted with cerebral aneurysm from October 2005 to March 2015 in our service. There were 31 cases of DACA aneurysms treated with the endovascular technique. These were compared with same topography aneurysms underwent to clipping. Results A total of 21 (67%) of 31 cases presented with ruptured aneurysms, 13 (59%) suffered clinical or radiological vasospasms, with modified Rankin Scale (mRS) scores of 3­5 in 7 patients (31%), and 4 deaths (mRS 6), reaching 92% of occlusion at one year. Conclusion Endovascular approach is associated with high angiographic occlusion rates and security.

Objetivo Para esclarecer a segurança e eficácia do tratamento endovascular dos aneurismas distais da artéria cerebral anterior distal (DACA), foram relatados os resultados de aneurismas embolizados em nosso serviço e comparados com séries de tratamento microcirúrgico. O impacto da embolização em aneurisma roto ou não roto permanece controverso com base nos dados atuais, considerando que o aneurisma dessa topografia deve ser tratado agressivamente devido à elevada incidência de ruptura, há uma tendência em preferir tratamento endovascular. Métodos Realizamos um estudo retrospectivo de 1092 pacientes admitidos com aneurisma cerebral entre Outubro de 2005 a Março de 2015 em nosso serviço. Haviam 31 casos de aneurisma da DACA tratados com a técnica endovascular. Estes foram comparados com aneurismas da mesma topografia tratados através de microcirurgia. Resultados Um total de 21 (67%) dos 31 pacientes apresentaram aneurisma roto, 13 (59%) sofreram vasoespasmo clínico ou radiológico, desfecho Escala de Rankin modificada (ERm) 3­5 em 7 (31%) pacientes e 4 mortes (ERm 6). A taxa de oclusão imediata foi de 96% e a taxa de oclusão em um ano de 92% com apenas uma recanalização. Conclusão A abordagem endovascular está associada com altas taxas de oclusão angiográfica e segurança no procedimento.
