OBJECTIVE  The aim of this study was to determine if either the rate of onset of clinical signs or duration from initial clinical signs to surgical decompression affected the overall quality or duration of recovery in dogs with intervertebral disc extrusion. STUDY DESIGN  This was a retrospective case series of 131 client owned dogs. Medical records of dogs surgically treated with hemilaminectomy for intervertebral disc extrusion between January 2016 and December 2017 were reviewed for signalment, neurological grade at presentation, rate of onset and duration of clinical signs and surgical variables. These variables were analysed to determine their effect on return of pain sensation, urinary continence and ambulation. RESULTS  Duration of clinical signs prior to surgery and rate of onset of signs did not correlate with return of pain sensation, urinary continence or ambulation. Preoperative neurological grade was the main variable that was found to be associated with outcome. CONCLUSIONS  Delay from initial clinical signs of intervertebral disc extrusion to surgery is unlikely to affect the ultimate outcome or the length of time for a dog to regain pain sensation, urinary continence or ambulation. The rate of onset of signs likewise does not influence these outcomes.

持续时间和临床体征发作对Hansen I型胸腰椎椎间盘突出症犬短期结果的影响。

目的本研究的目的是确定临床体征的发作率或从初始临床体征到手术减压的持续时间是否影响椎间盘突出症犬的总体质量或恢复时间。研究设计这是对131只客户拥有的狗的回顾性病例系列。回顾了2016年1月至2017年12月经半椎板切除术手术治疗的椎间盘突出症的狗的病历，包括信号，表现时的神经系统等级，发病率和临床体征持续时间以及手术变量。分析这些变量以确定它们对疼痛感，尿失禁和下床活动恢复的影响。结果手术前的临床体征持续时间和体征发作率与疼痛感的恢复无关，尿失禁或移动。术前神经系统学分是发现与预后相关的主要变量。结论从椎间盘突出的最初临床症状到手术的延迟不太可能影响最终结果或狗恢复疼痛感，尿失禁或下床活动的时间长度。体征的发作率同样不影响这些结果。
