腰椎术后硬膜外瘢痕研究进展

Research progress of epiduralscar after lumbars pinesurgery

腰椎间盘突出症患者在行椎板切除减压或椎间盘切除术后,仍存留下肢顽固性疼痛不适症状。这些不适的症状有可能由术后获得性椎管狭窄,相邻节段退变,椎间盘复发,腰椎滑脱以及硬膜外瘢痕等原因引起。其中,硬膜外瘢痕(神经根粘连、硬膜外纤维化)可能占20%~36%。有学者研究怎样减少硬膜外瘢痕的材料或方法,也有学者致力于术后硬膜外瘢痕的治疗。本文就硬膜外瘢痕研究进展做一综述。

Lumbar disc herniation in patients with laminectomy or discectomy after lower limb remained intractable pain symptoms. These symptoms of discomfort may be acquired by postoperative spi- nal stenosis, adjacent segment degeneration, intervertebral disc and lumbar spondylolisthesis recurrence caused by epidural scar and other reasons. Among them, the epidural scar （nerve root adhesion, epidural fibrosis ） may account for 20% to 36%. Some scholars have studied how to reduce the epidural scar mate- rials or methods, but also some scholars committed to the treatment of epidural scar after surgery. This paper made a review on the research progress of epidural scar.
