Description
Summary:Partial hemipelvectomy refers to the surgical removal of a pelvic segment, which is performed for pelvic bone neoplasms, severe fractures, or poor bone union. This study presents the cases of seven dogs, six of which have neoplasms involving the hip joint and one with severe pelvic canal narrowing due to a poorly consolidated trauma. Partial caudal hemipelvectomy was performed for all the dogs to improve the quality of life and delay euthanasia. Of the seven cases, six required the use of a polypropylene mesh for the pelvic wall closure, with 85.71% of them acquiring manageable complications in the postoperative period. Despite these complications, an overall improvement in the quality of life was reported to be signifcant in the operated animals due to the removal of the cause of pain or discomfort. Thus, it was concluded that partial hemipelvectomyis benefcial for dogs with pelvic conditions. Furthermore, the main complication due to the lack of a pelvic wall for primary occlusion was circumvented by using a polypropylene mesh, showing that possible complications in this procedure can be appropriately managed. Key words: chondrosarcoma, osteosarcoma, lipoma, complications. A hemipelvectomia parcial consiste na remoção de segmento pélvico, indicada para neoplasmas com envolvimento de ossos da pelve, fraturas graves ou má união óssea. Esse trabalho apresenta sete pacientes caninos, dos quais seis portadores de neoplasmas envolvendo a articulação coxofemoral e um com grave estreitamento do canal pélvico, resultado de traumatismo mal consolidado. Com o intuito de fornecer qualidade de vida aos cães e postergar a eutanásia, todos foram operados pela técnica de hemipelvectomia parcial média a caudal. Dos sete pacientes, seis necessitaram do uso de tela de polipropileno para fechamento da parede pélvica e apresentaram 85, 71 % de complicações manejáveis no pós-operatório. No entanto, a melhora na qualidade de vida dos animais operados foi signifcativa, tendo sido removida a causa da dor ou desconforto desencadeado pela alteração anatômica local. Conclui-se que a técnica é benéfca aos pacientes, tendo como principal complicação, a falta de parede pélvica para oclusão primária, contornada com uso de tela de polipropileno pelos autores. Palavras-chave: condrossarcoma, osteossarcoma, lipoma, complicações.
