Hemivértebra é uma anormalidade genética que acomete a coluna
vertebral dos cães, ocorrendo com freqüência em animais braquiocefálicos de
cauda “retorcida”, sendo encontrada nos formatos de cunha ou de borboleta. Esta
alteração congênita pode aparecer em qualquer seguimento da coluna vertebral,
entretanto é habitual encontrarmos nas vértebras torácicas e lombares.
Geralmente esta afecção é assintomática e os achados radiográficos são
incidentais. Em casos mais graves, essa anormalidade pode acarretar paresia
caudal dos nervos motores craniais, ataxia e paraparesia, podendo evoluir
durante o crescimento do animal. Em casos mais simples, quando há um
diagnóstico precoce, utiliza-se terapia farmacológica com uso de corticóides,
em casos mais severos ou quando os fármacos não se mostram eficazes a correção
cirúrgica (laminectomia descompressiva) passa ser a opção de tratamento.
