腰大池置管持续引流治疗胸椎黄韧带骨化术后脑脊液漏

目的探讨腰大池置管持续引流治疗胸椎黄韧带骨化术后脑脊液漏的效果。方法2003年3月～2011年3月对15例胸椎黄韧带骨化术后脑脊液漏应用一次性颅脑外引流器从L3-4椎间隙行硬膜外穿刺，置管于蛛网膜下腔引流脑脊液。结果切口引流时间2～8d，平均4d；腰大池置管时间3～10d，平均6d。15例术后随访6个月，无一例出现脑脊液复发、切口感染和颅内感染并发症。结论腰大池置管持续引流治疗胸椎黄韧带骨化术后脑脊液漏安全、有效。

Curative Effects of Continued Lumbar Cerebrospinal Fluid Drainage for Postoperative Cerebrospinal Fluid Leakage of Thoracic Ossification of Ligamentum Flavum

Objective To investigate the curative effects of continued lumbar cerebrospinal fluid drainage for postoperative cerebrospinal fluid leakage of thoracic ossification of ligamentum flavum（TOLF）. Methods Epidural puncture was conducted via L3-4 intervertebral space, then the epidural catheter was placed in subarachnoid space and connected with the disposable cerebral external drainage device for drainage of cerebrospinal fluid. Results Incision drainage time was 2 - 8 d, with an average of 4 d. Lumbar cistern intubation time was 3 - 10 d, with an average of 6 d. All the 15 cases were followed up for 6 months, and no recurrence of cerebrospinal fluid leakage, no incision infection or intracranial infection was observed. Conclusion Continued lumbar cerebrospinal fluid drainage is a safe and effective method for the treatment of postoperative cerebrospinal fluid leakage of TOLF.
