ABSTRACT
PURPOSE: This paper proposes a practical model of microneurosurgical training using a nonliving swine head. METHODS: Fresh porcine heads were obtained from butchery and dissected at our Laboratory of Microsurgery. Brain and skull base surgery were trained under microscopic magnification. RESULTS: Several neurosurgical procedures could be simulated in the nonliving pig model, including transcallosal approach to the lateral ventricle, lateral sulcus and middle fossa dissection, and posterior fossa surgery. CONCLUSION: The swine model perfectly simulates standard microneurosurgical procedures, and is a useful tool for developing and refining surgical skills. .

Objective: Evaluate clinical outcome of dorsal root ganglia (DRG) pulsed radiofrequency (PRF) treatment in neuropathic pain of patients with radiculopathy regarding improvement of pain and degree of patients? satisfaction. Method: Forty-five procedures in cervical and lumbossacral spine. Data collected by phone call interviews (independent researcher). Evaluation done after one month and at minimum three months follow-up. Analyzed data included objective and subjective improvement, and degree of satisfaction. Results: Outcome much better in 31%, 36% better, 24% unchanged, 9% worse. At initial evaluation, relief was rated: 24% excellent, 16% good, 27% moderate, 33% poor. At late evaluation, 27% excellent, 18% good, 7% moderate, 49% poor. Degree of satisfaction was high (82% of patients reported they certainly or probably would repeat the procedure). Conclusion: PRF was effective and safe in selected patients. Most patients were satisfied and would repeat/recommend the procedure...
Objetivo: Avaliar a evolução clínica do tratamento com radiofrequência pulsada (RFP) de gânglio da raiz dorsal (GRD) na dor neuropática em pacientes com radiculopatia, considerando melhora da dor e grau de satisfação dos pacientes. Método: Quarenta e cinco procedimentos na coluna cervical e lombossacra. Os dados foram coletados por meio de entrevistas telefônicas (pesquisador independente). Avaliação inicial feita após um mês e final no mínimo de três meses de acompanhamento. Dados analisados incluíram melhora objetiva, subjetiva e o grau de satisfação. Resultados: Evolução ?muito melhor? em 31%, ?melhor? em 36%, ?inalterado? em 24%, ?pior? em 9%. Na avaliação inicial: 24% ?excelente?, 16% ?bom?, 27% ?moderada?, 33% ?pobre?. Na avaliação final, 27% ?excelente?, 18% ?bom?, 7% ?moderada?, 49% ?pobre?. O grau de satisfação foi elevado (82% dos pacientes relataram que certamente ou provavelmente repetiriam o procedimento). Conclusão: RFP foi eficaz e segura em pacientes selecionados. A maioria dos pacientes ficou satisfeita e repetiu/recomendou o procedimento...

A neuralgia do trigêmeo é geralmente uma doença de idosos. Raramente, a doença apresenta-se durante a infância. Porisso, procuramos explorar o papel da compressão vascular em pacientes pediátricos com neuralgia do trigêmeo refratária.Apresentamos um caso de compressão venosa relacionado à neuralgia do trigêmeo em uma menina de 17 anos de idade. Aveia petrosa superior foi relacionada ao conflito neurovascular, com resposta incomum para descompressão neurovascular eresolução completa dos sintomas no pós-operatório...
Trigeminal neuralgia in general is a disease of the elderly. Rarely, the disease presents during childhood. Therefore we sought toexplore the role of vascular compression in pediatric patients with medically refractory trigeminal neuralgia. A case of venouscompression related to trigeminal neuralgia is presented in a 17-year-old girl. Upper petrous vein was found to be related to aneurovascular conflict with unusual response to neurovascular decompression with complete resolution of symptoms in postoperativeperiod...
