To identify the prevalence of recurrence of clinical signs after initial successful decompressive surgery for intervertebral disc extrusion in French bulldogs.
A medical record search was performed to identify French bulldogs that experienced an initial successful outcome after surgery for thoracolumbar or cervical intervertebral disc extrusion. Collected information included signalment, neurological examination findings, intervertebral disc extrusion location, presence of vertebral malformations, kyphosis, type and extent of surgery. Decompressive surgery was not followed by extensive prophylactic fenestrations. Follow-up information was retrieved from medical records and telephone interviews with referring veterinary surgeons.
Eighty-four French bulldogs with thoracolumbar (n=55) or cervical (n=29) intervertebral disc extrusion were included. Forty-three (51%) dogs that had decompressive surgery for thoracolumbar (n=29) or cervical (n=14) intervertebral disc extrusion suffered recurrence of signs. The median time between decompressive surgery and recurrence of clinical signs was 9 months and 21 days. Of the 29 dogs suffering recurrence of clinical signs following surgery for thoracolumbar intervertebral disc extrusion, 24 returned for recurrence of clinical signs localised to the thoracolumbar segments, while five returned for recurrence of signs localised to the cervical region. Of the 14 dogs who suffered recurrence of signs following surgery for cervical intervertebral disc extrusion, nine returned for signs localised to the cervical region, while five returned for clinical signs localised to the thoracolumbar region.
This study suggests a high rate of late onset recurrence of clinical signs after decompressive surgery for intervertebral disc extrusion in French bulldogs. This information can aid in the management of owner expectations.
确定法国斗牛犬初次成功减压手术后椎间盘突出的临床体征复发的流行率。
进行了病历检索，以确定接受胸腰椎或颈椎椎间盘突出减压手术并取得初次成功的法国斗牛犬。收集的信息包括品种、神经学检查结果、椎间盘突出位置、椎体畸形、脊柱后凸、手术类型和范围。减压手术后未进行广泛的预防性开窗术。通过病历和与转诊兽医的电话访谈获取随访信息。
共纳入 84 例胸腰椎（n=55）或颈椎（n=29）椎间盘突出的法国斗牛犬。43 只（51%）接受胸腰椎（n=29）或颈椎（n=14）椎间盘突出减压手术的犬出现体征复发。减压手术后至临床体征复发的中位时间为 9 个月零 21 天。29 只接受胸腰椎椎间盘突出减压手术后出现临床体征复发的犬中，24 只复发的临床体征局限于胸腰椎段，5 只复发的临床体征局限于颈椎段。14 只接受颈椎椎间盘突出减压手术后出现体征复发的犬中，9 只复发的临床体征局限于颈椎段，5 只复发的临床体征局限于胸腰椎段。
本研究表明，法国斗牛犬减压手术后椎间盘突出的临床体征复发率较高，且为晚期复发。这些信息有助于管理犬主的预期。
