ABSTRACT

Objetivou-se avaliar as implicações e os resultados obtidos frente aos tratamentos conservativo e cirúrgico em 37 cães sem distinção de sexo, raça ou idade, que apresentaram fraturas e luxações vertebrais (FLV) toracolombares. Cada paciente passou por anamnese, seguida por exames clínico, neurológico e radiográficos para se obter o diagnóstico neuroanatômico e a severidade da lesão. Os cães foram submetidos ao tratamento conservativo ou cirúrgico de acordo com as características de cada caso. Dos 37 animais deste estudo, 37,7% tinham percepção de dor profunda (PDP) intacta. Vinte animais foram submetidos ao tratamento conservativo, 14 ao tratamento cirúrgico e três animais faleceram antes do tratamento. Dos animais que mantiveram a PDP intacta, a taxa de recuperação foi de 100%, com tempo de recuperação total variando de sete a 75 dias, ao passo que, dos animais que perderam a PDP, nenhum recuperou a deambulação voluntária. Dos 14 animais operados, 42,8% apresentaram alterações vertebrais não visibilizadas ao exame radiográfico convencional, sendo necessária mudança na técnica cirúrgica planejada em 14,2% desses casos. Nos animais que mantiveram a PDP, não houve diferença significante nas taxas nem no tempo de recuperação da deambulação voluntária, independentemente do tipo de tratamento. Entretanto, houve diferença altamente significante entre os graus que mantiveram a PDP intacta com os animais que perderam a percepção de dor profunda em relação à taxa de recuperação. A taxa de eutanásia foi menor que em outros trabalhos descritos na literatura. Dos animais sem PDP submetidos ao tratamento conservativo ou cirúrgico, 31,25% readquiriram a capacidade de caminhar sem recuperar a PDP, sendo essa deambulação involuntária atribuída ao caminhar espinal.


Our aim of this paper was to study the implications and results associated with conservative and surgical treatment of dogs with thoracolumbar Vertebral fractures and luxations (VFL) so that the information obtained can be used to obtain guidelines that lead to greater recovery rates. For such, 37 dogs presenting VFL were examined, without distinction of sex, breed, or age. Each patient had detailed history obtained, followed by clinical, neurologic and radiographic exams for obtaining neuroanatomic location and severity of the nervous and vertebral lesions. The dogs were submitted to conservative or surgical treatment according to each case. Deep pain perception (DPP) was intact in 37.7% of the 37 dogs in this study. Twenty dogs received conservative treatment, 14 underwent surgery and three dogs died before treatment. Of the dogs with intact DPP, 100% recovered, with a recovery time varying between seven and 75 days, while none of the dogs that lost DPP recovered voluntary motion. Of the 14 dogs submitted to surgery, 42.8% had vertebral lesions that weren't detected using conventional radiography, which demonstrates the low sensitivity of this exam, and led to a need for a change in the planned surgical technique in 14.2% of these cases. In dogs with intact DPP there was no significant difference in time or rate of recovery of voluntary motion, regardless of the treatment method. However, there was a highly significant difference between the dogs which retained and lost DPP regarding recovery rates. The percentage of euthanasia was less than in other reports, probably due to the greater awareness and protectiveness of owners nowadays. Of the dogs without DPP treated either surgically or conservatively, 31.25% recovered ambulation without recovery of DPP, characterizing this ambulation as involuntary, attributed to spinal walk.

ABSTRACT

A 1-year-old castrated crossbred male cat was referred to the Veterinary Teaching Hospital for evaluation of urinary retention associated with a subluxation at T12-T13 caused by a car accident. Urethral sphincter denervation by transection of hypogastric and pudendal nerves was performed to allow bladder emptying, but after three months post operation the cat had a urinary retention recurrence. Endoscopic urethral sphincterotomy was done resulting in urinary incontinence for four months.


Um gato de um ano de idade, macho, castrado, sem raça definida, foi encaminhado ao Hospital Veterinário Escola para avaliação de retenção urinária associada à subluxação nas vértebras T12-T13, que foi causada por um acidente automobilístico. Realizou-se a denervação do esfíncter uretral, por transecção dos nervos pudendo e hipogástrico, para permitir o esvaziamento da bexiga, porém três meses após a cirurgia inicial o animal apresentou recorrência da retenção urinária. Esfincterotomia endoscópica uretral foi então realizada, resultando em incontinência urinária por quatro meses.
