“…A região cervical representa aproximadamente 15% dos casos de DDIV (Lemarié et al 2000). Essa alteração ocorre em raças condrodistróficas e não condrodistróficas (Toombs 1992, De Lahunta & Glass 2009), ocasionando extrusão (Hansen tipo I) ou protrusão (Hansen tipo II) do disco degenerado no interior do canal vertebral (Toombs & Bauer 1998, Sharp & Wheeler 2005.…”

O objetivo deste estudo foi identificar cães com doença do disco intervertebral (DDIV) cervical atendidos no Hospital Veterinário Universitário (HVU) da Universidade Federal de Santa Maria (UFSM) entre janeiro de 2003 e outubro de 2008 e obter informações a respeito de raça, sexo, idade, sinais neurológicos, resposta ao tratamento cirúrgico, complicações, tempo de recuperação funcional após a cirurgia e ocorrência de recidiva. Hiperestesia cervical foi observada em todos os cães (n=28). Quanto ao grau de disfunção neurológica foram verificados: grau I (8/28[28,5%]), grau II (3/28 [10,7%]), grau III (5/28[17,8%]) e grau V (12/2 [42,8%]). A duração dos sinais neurológicos antes da cirurgia em sete cães (25%) permaneceu por até 15 dias, em 14 cães (50%) entre 15 e 30 dias e nos outros sete cães (25%) por mais de 30 dias. A recuperação satisfatória e sem recidiva foi observada em todos os cães submetidos ao tratamento cirúrgico e que sobreviveram (n=21). Pode-se concluir que a DDIV cervical em nossa rotina acomete principalmente cães adultos, machos, de raças condrodistróficas e não condrodistróficas, incluindo as de grande porte; a hiperestesia cervical é a principal manifestação clínica; a técnica de fenda ventral promove recuperação funcional satisfatória e sem recidiva; as principais complicações trans-operatórias são a hemorragia do plexo venoso, a bradicardia e a hipotensão; e a duração dos sinais clínicos não interfere no tempo de recuperação pós-operatória dos cães.

“…However, when considering stability and vertebral body strength, there is a limitation in the size of the slot that can be safely performed [2,4]. Furthermore, it has been reported that cervical vertebral instability can occur secondary to ventral slot procedures in the caudal cervical spine [3,7,12]. In small dogs, particularly, adequate slot size may be difficult to achieve for the removal of the protruded disc material.…”

ABSTRACT. Hemilaminectomy was performed to treat cervical disc disease in 18 small dogs. Cervical spinal cord compression was characterized by ventral and/or lateral compression on myelograms. The duration of follow-up examinations ranged from 2 to 72 months. The optimal response time after surgery ranged from 2 days to 3 months. The outcome was determined to be excellent if clinical signs resolved and the dog had completely improved. The outcome was determined to be good if the dog improved, but was not clinically normal or if the degree of the owner's satisfaction was insufficient. Fourteen dogs achieved complete neurologic recovery without complications. One dog was initially neurologically worse after surgery, but ultimately improved to normal neurologic status. These outcomes were judged to be excellent. In the remaining 3 dogs, 2 dogs had relapse of neck pain and one dog remained mildly ataxic. These outcomes were judged to be good. These results suggest that hemilaminectomy is an effective option for surgical treatment of spinal cord compression secondary to cervical disc disease in small dogs. KEY WORDS: cervical disc disease, hemilaminectomy, small dog.

Case Description—An 11-year-old male breeding alpaca was evaluated for a 2-day history of lowered head carriage and lethargy. Clinical Findings—On initial examination, the alpaca had signs of lethargy and lowered carriage of the head and neck, but no specific neurologic deficits. Medical management improved the clinical signs, but 8 months later, the alpaca developed acute, progressive general proprioceptive ataxia affecting all 4 limbs and was referred for further evaluation and treatment. Magnetic resonance imaging and CT identified disruption of the normal osseous architecture of C7 and T1. Medical management was attempted, but because of a lack of improvement, the patient underwent surgery 14 months after initial examination. Treatment and Outcome—A dorsal laminectomy of C7 and T1 via a dorsal midline approach was performed, and the spinous processes of both vertebrae were removed prior to removal of the overlying lamina. Free dorsal expansion of the spinal cord was ensured by resection of the ligamentum flavum. Six months after surgery, the alpaca had returned to successful breeding with 7 hembra bred in the first year after surgery, producing 6 crias, and 4 crias in the second year. The patient was eventually euthanized 28 months after surgery because of neurologic deterioration but was still ambulatory at that time. Conclusions and Clinical Relevance—A good outcome with adequate alleviation of clinical signs and breeding soundness for > 2 years following dorsal laminectomy was achieved in this camelid patient. The surgical approach was similar to that in other species and was associated with mild postoperative morbidity. Veterinarians treating camelids should be aware of the initial clinical signs and treatment options for cervical vertebral stenotic myelopathy. In acute cases, the signs of reduced cervical mobility and pain on manipulation should prompt investigation including appropriate diagnostic imaging. Timely surgical intervention should be considered in patients that respond poorly to medical treatment to avoid irreversible spinal cord injury and optimize outcome.
