To determine whether prophylactic fenestration (PF) of adjacent intervertebral discs decreases the recurrence rate (RR) of cervical intervertebral disc extrusion (C-IVDE) in small dogs undergoing ventral slot (VS) decompression, and whether PF increases perioperative complication risk.
Retrospective, multi-institutional cohort study.
A total of 55 dogs.
Medical records of a mixed population of small dogs (<20 kg) treated with VS for C-IVDE with a minimum one-year follow-up were reviewed. During surgery, dogs underwent either single-site PF, multiple-site PF, or no PF. Perioperative complication rate and RR were compared between PF and non-PF groups using generalized linear models. Surgical time and neurologic grade (presurgery, post-surgery, at first recheck) were compared with Mann-Whitney test and chi-squared tests.
A total of 55 dogs were included (PF: n = 18; non-PF: n = 37). Neurologic grades were similar at all timepoints. Median time to first recheck was 14 days (range: 5-56). Median follow-up time was 1380 days (range: 365-2777). Recurrence occurred in 25% of dogs (14/55), all in the non-PF group. Prophylactic fenestration was associated with a lower RR (p < .001). Surgery duration was longer in the PF group (158.0 ± 13.5 min) versus non-PF (118.0 ± 6.8 min, p = .017), but complication rates were similar (18.2%, p = .838) between groups.
Recurrence of C-IVDE is more likely to occur at non-PF group than PF-group in a heterogenous population of small breed dogs. Prophylactic fenestration was not linked to increased complication risk.
Prophylactic fenestration might be safely considered to prevent C-IVDE recurrence.
确定在接受腹侧开槽（VS）减压的小型犬中，对相邻椎间盘进行预防性开窗（PF）是否能降低颈椎间盘突出症（C-IVDE）的复发率（RR），以及PF是否会增加围手术期并发症风险。
回顾性、多机构队列研究。
共55只犬。
回顾了接受VS治疗C-IVDE的小型犬（体重<20 kg）的混合群体的病历，随访时间至少为一年。手术过程中，犬只接受单部位PF、多部位PF或不进行PF。使用广义线性模型比较PF组和非PF组的围手术期并发症发生率和RR。采用Mann-Whitney检验和卡方检验比较手术时间和神经学分级（术前、术后、首次复查时）。
共纳入55只犬（PF组：n = 18；非PF组：n = 37）。所有时间点的神经学分级相似。首次复查的中位时间为14天（范围：5 - 56天）。中位随访时间为1380天（范围：365 - 2777天）。25%的犬（14/55）出现复发，均在非PF组。预防性开窗与较低的RR相关（p < .001）。PF组的手术时间（158.0 ± 13.5分钟）比非PF组（118.0 ± 6.8分钟，p = .017）长，但两组的并发症发生率相似（18.2%，p = .838）。
在小型犬的异质群体中，C-IVDE在非PF组比PF组更易复发。预防性开窗与并发症风险增加无关。
可安全考虑采用预防性开窗来预防C-IVDE复发。
