摘要

目的评估神经系统正常的肱骨 "螺旋尾 "犬种中胸椎先天性畸形(CVM)的发病率、类型、部位和品种倾向:研究设计:回顾性病例系列:研究设计:回顾性病例系列。动物:神经正常的法国斗牛犬(n = 63)、英国斗牛犬(n = 42)、波士顿梗犬(n = 4)和巴哥犬(n = 86),前来接受肱骨阻塞性气道综合征治疗:方法:根据 Guiterrez 等人提出的 "改良麦克马斯特椎体畸形分类法",对每只狗的胸部计算机断层扫描平片或胸椎侧位和背腹位数字X光片进行评估,看是否有椎体畸形。结果:法国斗牛犬中有一个或多个椎骨异常的比例为 96.82%,英国斗牛犬为 90.47%,巴哥犬为 76.74%。八哥犬的 CVM 发生率明显低于法国斗牛犬。四只波士顿梗犬均有脊椎畸形,但由于样本量较小,结果不具有统计学意义。在法国斗牛犬和英国斗牛犬中,腹侧畸形(类型 3)的发生率高于所有其他类型,其次是腹侧和中线畸形(类型 7)和对称性畸形(类型 8)。在巴哥犬中,对称性椎骨发育不良(8 型)最常见,其次是腹侧椎骨发育不良(3 型)。受影响最大的椎骨是巴哥犬的 T6-T9 椎骨,法国斗牛犬和英国斗牛犬的 T5-T10 椎骨:本文评估的大多数神经系统正常的肱骨 "螺尾 "犬都有一个或多个先天性胸椎畸形。发现患有脊椎畸形的犬更有可能有一个以上受影响的脊椎骨。性别对 CVM 的患病率没有影响:大量神经系统正常的肱骨 "螺旋尾 "犬患有先天性脊椎畸形。因此,必须实施选择性育种计划来消除这种遗传性疾病。

Prevalence and classification of congenital thoracic vertebral body abnormalities in neurologically normal brachycephalic ‘screw-tail’ dog breeds in referral practice in Australia

Objective

To evaluate the prevalence, type, site and breed predisposition of thoracic congenital vertebral malformations (CVM) in neurologically normal brachycephalic ‘screw-tail’ dog breeds.

Study Design

Retrospective case series.

Animals

Neurologically normal French Bulldogs (n = 63), British Bulldogs (n = 42), Boston Terriers (n = 4) and Pugs (n = 86) presenting for brachycephalic obstructive airway syndrome treatment.

Methods

Either a plain computer tomography scan of the thorax or lateral and dorso-ventral digital radiographs of the thoracic vertebral column of each dog were assessed for any vertebral malformations and classed according to the Modified McMaster vertebral abnormality classification scheme proposed by Guiterrez et al.

Results

The prevalence of dogs with one or more abnormal vertebrae was 96.82% in French Bulldogs, 90.47% in British Bulldogs, and 76.74% in Pugs. Pugs had significantly lower instances of CVMs than French Bulldogs. The four Boston Terriers all had vertebral malformations, but the results were not considered to be statistically significant due to their small sample size. In French Bulldogs and British Bulldogs, ventral hypoplasia (Type 3) occurred at greater rates than all other types, followed by ventral and median hypoplasia (Types 7) and symmetrical hypoplasia (Type 8). In Pugs, symmetrical hypoplasia (Type 8) was the most common and then ventral hypoplasia (Type 3). The most affected vertebrae were T6–T9 in Pugs and T5–T10 in French Bulldogs and British Bulldogs.

Conclusions

The majority of neurologically normal brachycephalic ‘screw-tail’ dogs assessed in this paper possessed one or more congenital thoracic vertebral malformations. Dogs with vertebral malformations were found to be more likely to have more than one affected vertebra. Sex had no effect on the prevalence of CVM.

Clinical Relevance

A substantial number of neurologically normal brachycephalic ‘screw-tail’ dogs suffer from congenital vertebral malformations. Thus, the need for selective breeding programmes to eliminate this hereditary condition is crucial.
