Presence of residual material following mini-hemilaminectomy in dogs (n = 9) with spontaneous thoracolumbar intervertebral disc extrusion was prospectively investigated. Volume of extruded disc material within the vertebral canal and the proportion of residual material were determined using pre- and post-operative magnetic resonance imaging. The degree of spinal cord compression, proportion of extradural material considered hemorrhage, and invasion of the articular facets were also determined. Residual material was identified in 44% of the mini-hemilaminectomies. The median percentage of residual material calculated was 7.7% of the preoperative volume. No observed effect of surgical side or site, proportion of extradural material considered hemorrhage, patient weight, and duration of clinical signs was detected.
对9只患有自发性胸腰椎椎间盘突出症的犬进行半椎板切除术,前瞻性研究术后残余物质的存在情况。利用术前和术后的磁共振成像确定椎管内椎间盘突出物质的体积以及残余物质的比例。同时还确定脊髓压迫程度、硬膜外物质中被认为是出血的比例以及关节突的侵犯情况。在44%的半椎板切除术中发现了残余物质。计算得出的残余物质的中位数百分比为术前体积的7.7%。未观察到手术侧别或部位、硬膜外物质中被认为是出血的比例、患者体重以及临床症状持续时间产生的影响。
