147例犬椎间盘疝出疾病回顾性分析

Retrospective analysis of 147 cases of canine intervertebral disc herniation

旨在分析犬椎间盘疝出疾病的发病情况及相关的风险因素,为临床上犬椎间盘疝出疾病的诊断、治疗和预防提供参考。本研究收集了147例经临床体格检查、神经学检查、核磁共振影像检查综合确诊为椎间盘疝出的病例,回顾性分析了犬椎间盘疝出的类型、发病部位,以及与动物品种、性别、年龄之间的关系。结果显示,4种椎间盘疝出类型中,椎间盘脱出发病数最多,占43.9%;椎间盘疝出部位中,C6-T2脊髓节段发病数最少,T3-L3脊髓节段发病数最多;综合分析动物品种、发病年龄和椎间盘疝出类型,软骨发育不良品种的椎间盘疝出更易发生于成年期,且以椎间盘脱出为主,而其他犬种椎间盘疝出更易发生于老年,以椎间盘突出为主。本研究综合分析椎间盘疝出疾病的发病特点和流行病学特征,填补国内研究空白,为该病临床诊疗提供参考资料。

This study was to investigate the incidence and related risk factors of intervertebral disc herniation, aiming to provide reference for clinical diagnosis, treatment and prevention of this disease. This study collected 147 cases of intervertebral disc herniation which were confirmed by clinical physical examination, neurological examination and magnetic resonance imaging, and retrospectively analyzed the type and site, as well as the relationship with animal species, gender and age of the disease. The results showed that the most common type for intervertebral disc herniation is disc extrusion(43.9%). The least common site of intervertebral disc herniation was spinal cord segments C6-T2, and the most is spinal cord segments T3-L3. By comprehensive analysis of animal species, age and type of herniation, intervertebral disc herniation in chondrodystrophic breedswas more likely to occur in adulthood and mainly caused by disc prolapse. In nonchondrodystrophic breeds, intervertebral disc herniation was more likely to occur in aged and mainly caused by disc protusion.
