Abstract: Primary or secondary bone tumors can manifest in different ways, from simple bone pain to possible pathological fractures. Hypervascularized tumors are of greatest concern, with increased incidence of complications. Preoperative embolization of the bone tumor is an effective measure for reducing blood loss during open surgery to excise the tumor. With appropriate experience, the risks of the procedure are minimal and final outcomes are highly satisfactory. The purpose of this paper is to describe the case of a 43-year-old male patient with a metastatic renal cell tumor in the left proximal femur (seen on lower limb computed tomography) who underwent selective preoperative embolization. The procedure resulted in a remarkable absence of bleeding and successful response to subsequent onco-orthopedic surgery.

Resumo: Os tumores ósseos, primários ou secundários, podem se manifestar de várias formas, desde dor óssea até fraturas patológicas. A preocupação maior repousa sobre tumores hipervascularizados, com maior incidência de complicações. A embolização pré-operatória do tumor ósseo é uma medida eficaz para reduzir a perda sanguínea durante a exérese tumoral em cirurgia aberta. Com uma experiência apropriada, os riscos do procedimento são mínimos, com resultados finais bastante satisfatórios. O presente artigo tem por finalidade descrever o caso de um paciente do sexo masculino, de 43 anos, com tumor metastático de células renais em fêmur proximal esquerdo (visualizado por angiotomografia de membro inferior), submetido à embolização arterial seletiva pré-operatória. O procedimento resultou em ausência de sangramento e ótima resposta à cirurgia onco-ortopédica realizada.
