脑脊液漏是脊柱外科手术一种常见的并发症，主要原因是术中发生硬脊膜破裂，是临床上面临的一个难题。脑脊液是一种保护大脑和维持颅内压的生理性液体，脑脊液漏若处理不当，可导致持续性头痛、恶心、呕吐，并增加脑膜炎的风险。正确有效的硬脊膜缝合和修补是恢复的基础，硬脊膜的修复难以通过药物途径得到缓解，因此脑脊液漏及时识别和细致修复，对于恢复和降低并发症至关重要。本文就近年相关不同的研究进行总结归纳，就脑脊液漏的病因和诊断及其修复方法等进行综述，为临床医师提供参考，以避免伤口和椎管内及颅内感染、延迟愈合、假性硬脊膜囊肿形成、脊髓神经受压等并发症发生，能对患者的快速康复有积极意义。“,”Cerebrospinal fluid leakage is one of the common complications of spinal surgeries. The causes of the leak can be dural tears during surgery procedure and this is a medical problem.Cerebrospinal fluid is a physiological fluid that protects the brain and maintains intracranial pressure. If it\'s not handled properly, it will cause persistent headaches, nausea, vomiting, and carry an increased risk of meningitis. Correct and effective dural suture and repair are the basis of recovery. The repair of dura mater is difficult to be alleviated by medicine, so it is very important to identify and repair cerebrospinal fluid leakage in time. In this review, the relevant studies in recent years are summarized. We discuss the pathogenesis of dural tears, diagnosis, repair methods. We provide references for clinicians to avoid delayed wound healing, wound infection, spinal canal and intracranial infection, pseudodural cyst, spinal cord nerve compression and other serious complications. This paper aims to assist in delivering efficacious treatment and recovery for patients.
