Abstract

Objective: To evaluate the feasibility of minimally invasive integrated endoscopic mini-hemilaminectomy and thoracolumbar lateral corpectomy at six intervertebral disc spaces in the canine thoracolumbar vertebral column.

Study design: Experimental, randomized cadaveric study.

Animals: Eight cadaver dogs euthanized for reasons unrelated to this study.

Methods: Preoperative computed tomography (CT) scans were performed for surgical planning. Using an endoscopic system, mini-hemilaminectomy and thoracolumbar lateral corpectomy were performed from the T11-12 through L3-4 intervertebral disc spaces, with cadavers in sternal recumbency or positioned at a 30°-60° angle. Postoperative CT scans were used to measure corpectomy dimensions as a percentage of total vertebral dimensions.

Results: Median ± interquartile range (IQR) corpectomy dimensions were 23.07% ± 16.47% of vertebral body length, 46.76% ± 21.7% of vertebral body height, and 74.44% ± 47.37% of vertebral canal diameter. Targeted dimensions were achieved at all surgical sites from T11-12 through L3-4.

Conclusion: Integrated endoscopic thoracolumbar lateral corpectomy was successfully performed at all intervertebral disc spaces from T11-12 through L3-4 using an endoscopic system, although thoracic sites required more practice.

Clinical significance: This pilot study will guide further clinical applications of minimally invasive neurosurgery in small animal patients.

综合内镜下胸腰椎小半椎板切除术和侧体切除术在尸体犬中的应用。

目的：探讨犬胸腰椎6个椎间盘间隙的微创内镜微创半椎板切除术和胸腰椎外侧椎体切除术的可行性。研究设计：实验，随机尸体研究。动物：8只尸体狗因与本研究无关的原因被安乐死。方法：术前进行计算机断层扫描（CT），制定手术计划。采用内镜系统，从T11-12至L3-4椎间盘间隙行小半椎板切除术和胸腰椎外侧椎体切除术，尸体胸骨平卧或定位为30°-60°角。术后CT扫描用于测量椎体切除尺寸占总椎体尺寸的百分比。结果：椎体切除尺寸中位数±四分位间距（IQR）为椎体长度的23.07%±16.47%，椎体高度的46.76%±21.7%，椎管直径的74.44%±47.37%。从T11-12到L3-4的所有手术部位均达到了目标尺寸。结论：使用内镜系统，从T11-12到L3-4的所有椎间盘间隙均成功实施了胸椎侧位椎体整体内镜切除术，尽管胸椎部位需要更多的练习。临床意义：本研究将指导微创神经外科在小动物患者中的进一步临床应用。

期刊介绍： Veterinary Surgery, the official publication of the American College of Veterinary Surgeons and European College of Veterinary Surgeons, is a source of up-to-date coverage of surgical and anesthetic management of animals, addressing significant problems in veterinary surgery with relevant case histories and observations. It contains original, peer-reviewed articles that cover developments in veterinary surgery, and presents the most current review of the field, with timely articles on surgical techniques, diagnostic aims, care of infections, and advances in knowledge of metabolism as it affects the surgical patient. The journal places new developments in perspective, encompassing new concepts and peer commentary to help better understand and evaluate the surgical patient.
