ABSTRACT

OBJETIVO: Avaliar a eficácia da técnica microcirúrgica utilizada para ressecção completa dos ependimomas intramedulares sem agregar déficits aos pacientes, em especial, aos pacientes funcionalmente independentes no pré-operatório. MÉTODO: Este estudo avaliou, segundo a escala funcional de McCormick, a evolução pós-operatória de uma série de 20 pacientes submetidos à ressecção microcirúrgica total para ependimomas intramedulares. RESULTADOS: A ressecção completa foi atingida em 19 dos 20 pacientes (95%) e somente um paciente apresentou piora clínica (5%). Nos pacientes com independência funcional pré-operatória, com McCormick grau I e II, não houve piora clínica e todos os tumores foram ressecados completamente. No subgrupo de pacientes grau II, a média do status funcional pós-operatória apresentou melhora estatisticamente significativa. Nenhum paciente com grau IV melhorou após o tratamento cirúrgico. CONCLUSÃO: O tratamento cirúrgico foi eficaz para ressecar completamente os tumores sem agregar déficits neurológicos na maioria dos pacientes. Nos pacientes com McCormick graus I e II pré-operatórios a cirurgia deve ser indicada no momento do diagnóstico.


OBJECTIVE: Evaluate the efficacy of the microsurgery technique used aiming total tumor resection without causing neurological deficits, with special attention to the patients with good functional status before surgery. METHOD: This study has evaluated according to the McCormick functional scale the surgical outcome of a series of twenty patients with intramedullary ependymomas submitted to microsurgical resection. RESULTS: Total surgical resection was achieved in 19 of the 20 patients (95%). Only one patient experienced clinical worsening (5%). Patients classified as McCormick grade I and II who were independent pre-operatively remained so in the post-operative period and had their tumors completely removed. In grade II patients there was a significant improvement in their post-operative status. None of the grade IV patients improved after surgical treatment. CONCLUSION: Surgical treatment has proven to be efficient in completely removing tumors without adding neurological deficits in most patients. In patients with McCormick grades I and II pre-operatively surgery should be indicated early in the diagnosis.
