Clinical reports have suggested that myelography and laminectomy may produce more arachnoiditis than myelography alone. The effect of experimental lumbar myelography and laminectomy on arachnoiditis in monkeys was studied. Arachnoiditis was as severe after myelography alone as after myelography and laminectomy. Minimal arachnoiditis was found myelographically and histologically after myelography with metrizamide 300 mg l/ml, and severe arachnoiditis was found after myelography with iophendylate whether or not laminectomy was performed. Laminectomy alone produced insignificant arachnoid changes. Experimental myelography preceding laminectomy did not increase the risk of arachnoiditis.
临床报告表明，脊髓造影和椎板切除术可能比单纯脊髓造影引发更多蛛网膜炎。本研究了实验性腰椎脊髓造影和椎板切除术对猴子蛛网膜炎的影响。单纯脊髓造影后的蛛网膜炎与脊髓造影加椎板切除术后的一样严重。用300mg碘苯六醇/ml进行脊髓造影后，在脊髓造影和组织学检查中发现轻微蛛网膜炎，而用碘苯酯进行脊髓造影后，无论是否进行椎板切除术，均发现严重蛛网膜炎。单纯椎板切除术引起的蛛网膜变化不明显。在椎板切除术前行实验性脊髓造影不会增加蛛网膜炎的风险。
