In the context of veterinary medicine, minimally invasive techniques for feline spinal surgery remain underexplored, particularly for percutaneous laser disc ablation (PLDA) when using the Holmium:YAG (Ho:YAG) laser. This study aimed to refine the application of the Ho:YAG laser in PLDA by determining the optimal laser intensity and safe insertion angles for the thoracic and lumbar intervertebral discs (IVDs) in cats. Through utilizing computed tomography (CT) for precise guidance, this research involved a cadaveric study of 10 cats to evaluate the spatial configurations that allow for safe needle insertions and effective laser ablation. Various energy settings of the Ho:YAG laser (20 J, 40 J, and 60 J) were tested to ascertain the balance between adequate disc vaporization and minimal adjacent tissue damage. The results demonstrate that a 40 J setting is the most effective in achieving significant disc decompression without compromising surrounding tissue integrity. Additionally, the CT scans proved crucial in confirming the accuracy of the needle placement and the safety of the laser application angles. This study established that the 40 J setting on the Ho:YAG laser, combined with CT-guided insertion techniques, offers a reliable method for PLDA, thus enhancing the safety and efficacy of feline spinal surgeries.
在兽医学领域，猫科动物脊柱手术的微创技术仍未得到充分探索，尤其是使用钬：钇铝石榴石（Ho:YAG）激光进行经皮激光椎间盘消融术（PLDA）时。本研究旨在通过确定猫胸椎和腰椎椎间盘（IVD）的最佳激光强度和安全插入角度，优化Ho:YAG激光在PLDA中的应用。通过利用计算机断层扫描（CT）进行精确引导，本研究对10只猫进行了尸体研究，以评估允许安全插入针头和有效激光消融的空间构型。测试了Ho:YAG激光的各种能量设置（20 J、40 J和60 J），以确定在充分的椎间盘汽化和最小的相邻组织损伤之间的平衡。结果表明，40 J的设置在实现显著的椎间盘减压而不损害周围组织完整性方面最为有效。此外，CT扫描在确认针头放置的准确性和激光应用角度的安全性方面被证明至关重要。本研究确定，Ho:YAG激光的40 J设置与CT引导的插入技术相结合，为PLDA提供了一种可靠的方法，从而提高了猫科动物脊柱手术的安全性和有效性。
