Pediculectomy and fenestration for spinal cord decompression of the lumbar spine of a bush dog (Speothos venaticus) - case report

Abstract

A captive adult male bush dog (Speothos venaticus) was referred to our Veterinary Medical Teaching Hospital from a local zoo due to a two-week history of progressive hind limb gait impairment and ataxia, non-responsive to clinical management. Computed tomography revealed decreased disc space at L3 - L4 level, with probable disc extrusion narrowing the right side of the spinal canal, compressing the spinal cord. We opted to surgically remove the disc material using both fenestration and right lateral pediculectomy (mini-hemilaminectomy) techniques. Twelve days after surgery there was mild residual proprioceptive ataxia. Gait was fully regained with remission of the neurological deficits around the 30th postoperative day. This is - to the best of our knowledge - the first successful report of a lumbar intervertebral disc extrusion in a bush dog (Speothos venaticus) surgically treated by pediculectomy and disc fenestration.

Descompressão medular e de raiz nervosa pela técnica cirúrgica de pediculectomia: Relato de caso

“…Segundo Arias et al (2007) e Martins & Ferreira (2018) o trauma medular é uma das entidades neurológicas mais frequentes e mais graves na prática clínica, cabendo ao médico veterinário considerar a lesão medular aguda uma emergência, pois a instituição rápida do tratamento é fator crítico na limitação da degeneração e necrose do tecido neuronal. A compressão da medula espinhal leva ao comprometimento da marcha e até mesmo a paralisia em cães domésticos (Marinho et al, 2020).…”
