Conclusion: After laminectomy amniotic membrane is an effective biocompatible material in preventing epidural adhesion, and chitosan membrane has also showed certain effect. 结论:羊膜能预防硬膜外瘢痕向椎管内延伸,防止硬膜外粘连,是一种能有效预防硬膜外粘连的生物相容性材料;几丁糖膜亦显示了一定的预防硬膜外粘连作用。
Amniotic membrane may be a kind of proper transplantation material against the adhesion of spinal canal and tendon after operation. 羊膜可能为一种较理想的防止椎管内及肌腱等术后黏连的移植材料。
Objective: To investigate the role of amniotic membrane in the prevention of epidural adhesion after laminectomy and to find out the related mechanism. 目的:探讨羊膜在预防椎板切除术后硬膜外粘连的作用及可能机制。
We could consider to make use of HA plates wrapped by amniotic membrane to repair these injuries, such as orbital fracture of the larger, heavier adhesion, or old fractures like those patients needing the second surgery. 4临床中诸如眼外伤后眼眶骨折范围较大,粘连较重,或陈旧性骨折、需要二次手术的病人,涉及应用填充物修复防止粘连的问题,可以考虑羊膜包裹填充物移植。
